The present disclosure relates to a vehicle control technology field, and more particularly to an electric vehicle and a discharging apparatus thereof
With the development of science and technology, fuel vehicles are being replaced by environment friendly and energy saving electric vehicles. However, the popularization of the electric vehicles encounters some problems, among which high driving mileage and fast charging technology has become major problems in the promotion of electric vehicles.
Currently, large-capacity batteries are used in most electric vehicles. However, although these batteries may enhance the endurance time of the electric vehicle, they make a charging time too long. Although a specialized DC (direct current) charging station may charge a battery quickly, problems such as high cost and large occupied area make the popularity of such an infrastructure encounter a certain difficulty. Moreover, because of a limited space of an electric vehicle, an in-vehicle charger may not satisfy the requirement of a charging power due to the limitation of its volume.
A charging solution currently used in the market comprises the following solutions.
Solution (1)
As shown in
Solution (2)
As shown in
Therefore, most AC charging technologies currently used in the market are a single-phase charging technology, which has disadvantages including low charging power, long charging time, large hardware volume, single function, restriction by voltage levels of different regional grids, etc.
In addition, the electric vehicle only supplies the electric energy stored in the power battery to the motor so that the motor drive electric vehicles to move. While the electric vehicle is in OK gear, after the electric vehicle collects the gear signal and the throttle signal, the motor driving controller inverts DC supplied by the battery into AC and outputs the AC to the motor. Then the motor rotates to drive the electric vehicle. The power battery with large capacity and good quality is mounted in the electric vehicle as an energy storage device. The power battery is merely used as a power supply device, which limits uses of the energy stored in the power battery.
With the development of science and technology, people's life has become more and more comfortable, and developments of various fields more and more touch life. The electric vehicle only supplies the electric energy stored in the power battery to the motor so that the motor drive electric vehicles to move. While the electric vehicle is in OK gear, after the electric vehicle collects the gear signal and the throttle signal, the motor driving controller inverts DC supplied by the battery into AC and outputs the AC to the motor. Then the motor rotates to drive the electric vehicle.
Embodiments of the present disclosure seek to solve at least one of the problems existing in the related art to at least some extent.

The electric vehicle broadens an application range of electric vehicles, such that the electric vehicle may provide a convenient household power supply for people at any time. A second object of the present disclosure is to provide an electric vehicle.

The electric vehicle can be normally used for supplying electric energy as long as the household appliance is connected with the multi-plug socket. The discharging apparatus for the electric vehicle broadens the application range of electric vehicles, such that the electric vehicle may provide a convenient household power supply for people at any time.

The controller 140 is configured to communicate with the instrument 130 and to detect whether the charging connection device 120 is connected with the AC charging interface 110 after receiving a discharging preparation instruction sent from the instrument 130 when the instrument 130 receives a trigger signal. If the charging connection device 120 is connected with the AC charging interface 110, the controller 140 switches to an external discharging mode. In some embodiments of the present disclosure, the external discharge mode may be a three-phase discharge mode or a single-phase discharge mode.
Specifically, the instrument 130 and the controller 140 are communicated via a CAN bus of a local area network of the controller 140, and the controller 140 and the battery manager 150 are communicated via the CAN bus.
Furthermore, the controller 140 is further configured to determine whether the electric vehicle is currently in P gear after it is determined that the charging connection device 120 is connected with the AC charging interface 110, and if yes, the controller 140 switches to the external discharging mode. The controller 140 is further configured to detect in real-time whether an internal circuit of the controller 140 has a fault and to detect in real-time whether the exterior equipment has a fault during discharging. The controller 140 is further configured to stop outputting the AC (such as a single-phase AC or a three-phase AC) if it is determined that the internal circuit of the controller has a fault and/or the exterior equipment has a fault. The controller 140 is further configured to stop outputting the AC after receiving a discharging finish instruction from the instrument 130. The controller 140 is further configured to detect a current discharging current in real-time. The AC may be 220V/50 Hz. In another embodiment, the three-phase AC may be used, and a discharging voltage of the three-phase AC may be adjusted to meet a usage standard of the household appliance.
The battery manager 150 is configured to communicate with the controller 140 and to control an external discharging circuit in a high-voltage distribution box of the electric vehicle to be connected after the controller switches to the external discharging mode.
Specifically, the battery manager 150 is further configured to detect in real-time a current electric quantity of the power battery and whether the power battery 160 has a fault, if it is determined that the power battery 160 has a fault, the battery manager 150 sends a battery fault instruction to the controller 140, and the controller 140 stops outputting the AC after receiving the battery fault instruction.
The power battery 160 is connected with the high-voltage distribution box and is configured to provide a DC by the external discharging circuit in the high-voltage distribution box.
The controller 140 is configured to invert DC provided by the external discharging circuit into AC, and the AC is output to the AC charging interface 110 so as to discharge to the exterior equipment, i.e. to charge the exterior equipment.
With the discharging apparatus for the electric vehicle according to embodiments of the present disclosure, when the electric vehicle is set in a mode of discharging to a household appliance and in OK gear, and the vehicle-to-MPS discharging connection device is connected to the electric vehicle, after the electric vehicle detects a normal connection without fault, the electric vehicle may output a household electricity of the same voltage grade and the same frequency as a power grid via the AC charging interface of the electric vehicle. The electric vehicle can be normally used to provide electric energy as long as the household appliance is connected with the multi-plug socket. The discharging apparatus for the electric vehicle broadens the application range of electric vehicles, such that the electric vehicle may provide a convenient household power supply for people at any time.
As shown in
Specifically, because the electric vehicle is only used as a power supply when it supplies power externally and there is no CP signal (i.e., a control confirmation signal) providing interaction between the exterior equipment and the electric vehicle, the CP signal line is not required to be included in the vehicle-to-MPS discharging connection device, and only a CC signal line (i.e., a connecting confirmation signal line, also referring to a PP signal line in Europe standard) is required. A resistance of the CC signal line is set as 470 Ω to distinguish from a charging state, such that the controller may confirm that the electric vehicle in the mode of discharging to the household appliance.
Furthermore, when the electric vehicle is in OK gear and set in the mode of discharging to the household appliance, and the vehicle-to-MPS discharging connection device is connected to the electric vehicle, after the electric vehicle detects a normal connection without fault, the electric vehicle outputs a household electricity of the same voltage grade and the same frequency as a power grid via the AC charging interface of the electric vehicle. The electric vehicle can be normally used as a power supply as long as the household appliance is connected with the multi-plug socket.
The power system for the electric vehicle according to an embodiment of the present disclosure includes a power battery 10, a charging-discharging socket 20, a bidirectional DC-DC module 30, a driving control switch 40, a bidirectional DC-AC module 50, a motor control switch 60, a charging-discharging control module 70 and a controller module 80. In some embodiments of the present disclosure, the external discharging circuit in the high-voltage distribution box refers to the charging-discharging control module 70, the bidirectional DC-DC module 30 and the bidirectional DC-AC module 50. When the power system is controlled to be at an external discharging state, the external discharging circuit may externally discharge.
The bidirectional DC-DC module 30 has a first DC terminal a1 connected with a first terminal of the power battery 10, and a second DC terminal a2 connected with a second terminal of the power battery 10. The first DC terminal a1 is a common DC terminal for an input to and an output from the bidirectional DC-DC module 30. The driving control switch 40 has a first terminal connected with the second terminal of the power battery 10, and a second terminal connected with a third DC terminal a3 of the bidirectional DC-DC module 30. The bidirectional DC-AC module 50 has a first DC terminal b1 connected with the second terminal of the driving control switch 40, and a second DC terminal b2 connected with the first terminal of the power battery 10. The motor control switch 60 has a first terminal connected with an AC terminal c of the bidirectional DC-AC module 50, and a second terminal connected with a motor M. The charging-discharging control module 70 has a first terminal connected with the AC terminal c of the bidirectional DC-AC module 50, and a second terminal connected with the charging-discharging socket 20. The controller module 80 is connected with the driving control switch 40, the motor control switch 60 and the charging-discharging control module 70 respectively, and configured to control the driving control switch 40, the motor control switch 60 and the charging-discharging control module 70 according to a current operation mode of the power system.
Further, in some embodiments, the current operation mode of the power system may include a driving mode and a charge-discharge mode. When the current operation mode of the power system is the driving mode, the controller module 80 controls the driving control switch 40 to turn on in order to stop the bidirectional DC-DC module 30, controls the motor control switch 60 to turn on to drive the motor M normally, and controls the charging-discharging control module 70 to turn off. When the current operation mode of the power system is the charge-discharge mode, the controller module 80 controls the driving control switch 40 to turn off to start the bidirectional DC-DC module 30, controls the motor control switch 60 to turn off to remove the motor M, and controls the charging-discharging control module 70 to turn on in such a way that an external power source may charge the power battery 10 normally. The first DC terminal al and the third DC terminal a3 of the bidirectional DC-DC module 30 are connected with a positive terminal and a negative terminal of a DC bus respectively.
As shown in
As shown in
Moreover, as shown in
Generally, a leakage current is large in an inverter and grid system without transformer isolation. Therefore, with the power system according to embodiments of the present disclosure, the leakage current reducing module 102 is connected between the positive terminal and the negative terminal of the DC bus, thus reducing the leakage current effectively. The leakage current reducing module 102 includes two capacitors C2 and C3 of the same type, the capacitor C2 is connected between the negative terminal of the DC bus and a three-phase AC neutral point potential, the capacitor C3 is connected between the positive terminal of the DC bus and the three-phase AC neutral point potential, and a high-frequency current may be fed back to a DC side when the power system operates, thus effectively reducing a high-frequency leakage current generated when the power system operates.
In one embodiment, as shown in
The filtering module 103 is connected between the bidirectional DC-AC module 50 and the charging-discharging control module 70. Specifically, as shown in
As shown in
The second pre-charging control module 106 is connected in parallel with the charging-discharging control module 70 and configured to pre-charge capacitors C4, C5, C6 in the filtering module 103. The second pre-charging control module 106 includes three resistors RA, RB, RC connected in series and a three-phase pre-charging switch K9.
In one embodiment, as shown in
In other words, when the power system is powered on, the controller module 80 controls the first switch K1 to turn on to pre-charge the first capacitor C1 in the bidirectional DC-DC module 30 and the bus capacitor C0; and when the voltage across the bus capacitor C0 is a predetermined multiple of the voltage of the power battery 10, the controller module 80 controls the first switch K1 to turn off and controls the second switch K2 to turn on. In this way, the bidirectional DC-DC module 30 and the large-capacity bus capacitor C0 directly connected between power buses (i.e. DC buses) constitute main components for implementing a battery low-temperature activation technology, which is adapted to transfer the electric energy of the power battery 10 to the large-capacity bus capacitor C0 via the bidirectional DC-DC module 30, and to transfer the electric energy stored in the large-capacity bus capacitor C0 to the power battery 10 via the bidirectional DC-DC module 30 (i.e. when charging the power battery 10) after an electric quantity of the bus capacitor C0 reaches a predetermined value. Therefore, the charging and discharging cycle of the power battery 10 makes the temperature of the power battery 10 increase to an optimum operation temperature range.
When the current operation mode of the power system is the driving mode, the controller module 80 controls the driving control switch 40 to turn on to stop the bidirectional DC-DC module 30, controls the motor control switch 60 to turn on to drive the motor M normally, and controls the charging-discharging control module 70 to turn off. It should be noted that, although in some embodiments, the motor control switch 60 includes three switches connected with a three-phase input of the motor, in other embodiments, the motor control switch 60 may also include two switches connected with a two-phase input of the motor, or even one switch, provided that the control on the motor may be realized. Therefore, other embodiments will not be described in detail herein. In this way, a DC from the power battery 10 is inverted into an AC by means of the bidirectional DC-AC module 50, and the AC is transmitted to the motor M. The operation of the motor M can be controlled by a revolving transformer decoder technology and a space vector pulse width modulation (SVPWM) control algorithm.
When the current operation mode of the power system is the charge-discharge mode, the controller module 80 controls the driving control switch 40 to turn off to start the bidirectional DC-DC module 30, controls the motor control switch 60 to turn off to remove the motor M, and controls the charging-discharging control module 70 to turn on in such a way that an external power source such as a three-phase power source or a single-phase power source may charge the power battery 10 via the charging-discharging socket 20 normally. In other words, by detecting a charge connection signal, an AC grid electric system and relevant information on whole vehicle battery management, a controllable rectification function may be performed be means of the bidirectional DC-AC module 50, and the in-vehicle power battery 10 may be charged by the single-phase power source and/or the three-phase power source via the bidirectional DC-DC module 30.
With the power system for the electric vehicle according to embodiments of the present disclosure, the electric vehicle can be charged under a high power by means of a civil or industrial AC grid, such that a user may perform the charging efficiently, promptly, anytime and anywhere, thus saving a charging time. Moreover, a constant-voltage control device or a constant-current control device is not required, thus saving space and cost and having a wide battery operation voltage range.
Specifically, as shown in
The vehicle-to-MPS discharging connection device is mainly used to connect the two electric vehicles.
Specifically, during the V-to-HI, following modules are involved into operation: the instrument, the battery manager, the high-voltage distribution box, the controller, the AC charging interface, and the power battery. The instrument is configured to sample a discharging switch signal and a discharging mode signal, and to display discharging information and fault information. The battery manager is configured to sample state information of the power battery, to determine whether the power battery is allowed to externally discharge, and to control to connect a power supply circuit in the high-voltage distribution box. The high-voltage distribution box is configured to connect the power battery and the controller, such that the power battery may supply DC to the controller. The controller is configured to invert the DC supplied by the power battery into an AC. The controller is communicated with the instrument and the battery manager via the CAN. The AC charging interface is configured to connect the controller and the exterior household appliance, such that the AC provided by the controller can be output externally. The power battery is configured to store electric energy and to externally discharge the stored electric energy if it is required.
With the electric vehicle, a motor driving controller is further expanded in function of inverting the DC into the AC. The improved electric vehicle may supply household AC. Furthermore, when the power grid is out of service or for a place uncovered by the power grid, the electric vehicle may be temporarily used as a charging device to supply household AC to deal with emergencies. It significantly broadens an application range of electric vehicles, thus easing people's life.
A process of the V-to-HI may include a preparation period, a discharging period and a discharging finish period.
Furthermore, when the controller is in service, it is first determined whether there is an electric vehicle gear signal, if yes, the electric vehicle enters the driving mode; and if no, the controller detects a CC signal to determine whether the charging gun is connected to the vehicle after receiving the message indicating “discharging mode” from the instrument. Specifically, the controller needs to determine whether the charging interface CC signal is connected and whether a resistance of CC is 470 Ω. If the CC signal is not detected and the resistance of CC is not 470 Ω, a message indicating “forbid external discharge” is sent to the instrument. If the CC signal is detected and the resistance of CC is 470 Ω, it is further determined whether the electric vehicle is in P gear and whether the motor is in undriving mode. If the electric vehicle is not in P gear and the motor is not in undriving mode, a message indicating “forbid external discharge” is sent to the instrument. If the electric vehicle is in P gear and the motor is in undriving mode, the controller switches the internal circuit thereof to an external discharge mode. A gear shifting instruction is not replied during the discharging. The controller performs a self-detection, and if there is no fault, the controller sends a message indicating “discharging preparation of the controller is in ready”. It is determined whether a message indicating “preparation of the power battery is in ready” is received, and if yes, the message indicating “preparation of the controller is in ready” is sent, an AC output switch is turned on and a message indicating “get ready to external discharge” is sent. If the message indicating “preparation of the power battery is in ready” is not received, the message indicating “forbid external discharge” is sent to the instrument.
When it starts to work, the battery manager first self-detects whether it is able to externally discharge, and if no, a message indicating “forbid to discharge” is sent. A condition of forbiddance of discharge includes any one of an over-high temperature of the power battery, an over-low temperature of the power battery, an over-low voltage of the power battery and an over-low SOC. When receiving the message indicating “preparation of the controller is in ready”, the battery manager controls the external discharging circuit in the high-voltage distribution box to be connected and sends the message indicating “preparation of the power battery is in ready”.
Furthermore, after receiving the message indicating “preparation of the power battery is in ready”, the controller connects an external output and gets ready to work, that is, the household AC is externally supplied, and a message indicating “start to discharge” is sent.
During the V-to-HI discharging period and the V-to-HI discharging finish period, specifically, the instrument keeps displaying the discharging state of the electric vehicle; the controller keeps detecting whether there is a message indicating “the discharging is finished” from the instrument, whether the controller has a fault, whether the exterior equipment has a fault, and whether the power battery has a fault; and the battery manager keeps detecting the state of the power battery and whether the battery system has a fault.
The controller stops externally outputting the AC if any of following cases occurs. When receiving the message indicating “the discharging is finished” from the instrument, the controller stops externally outputting the AC and sends the message indicating “the discharging is finished”, and after receiving the message indicating “the discharging is finished”, the battery manager switches an internal circuit in the high-voltage distribution to reset the electric vehicle in OK gear. When receiving a message indicating “a battery system fault” sent from the battery manager, the controller stops externally outputting the AC, and the instrument displays the fault. When receiving a message indicating “an exterior equipment fault”, the controller stops externally outputting the AC, and the instrument displays the fault, in which the fault of the exterior equipment includes any one of over current, short circuit, connection fault and a combination thereof When it is determined the controller has a fault on itself, the controller stops externally outputting the AC and sends a message indicating “a controller fault”, the instrument receives the message indicating “a controller fault” and displays the fault, and the battery manager switches to a corresponding state according to the fault.
Furthermore, during the external discharging, the controller stops externally outputting the AC if any of following cases occurs: SOC of the power battery is over-low, and a discharge control button is pressed to terminate external discharging.
With the discharging apparatus for the electric vehicle according to embodiments of the present disclosure, when the electric vehicle is in OK gear and set in the mode of discharging to the household appliance, and the vehicle-to-MPS discharging connection device (i.e., the charging connection device) is connected to the electric vehicle, after the electric vehicle detects a normal connection without fault, the electric vehicle outputs a household electricity of the same voltage grade and the same frequency as the power grid via the AC charging interface of the electric vehicle. The electric vehicle can be normally used for outputting electric energy as long as the household appliance is connected with the multi-plug socket. The discharging apparatus for the electric vehicle broadens the application range of electric vehicles, such that the electric vehicle may provide a convenient household power supply for people at any time.
