To illustrate more clearly the embodiments in the present disclosure or the technical schemes of the prior art, a brief introduction of the accompanying drawings in the embodiments or the description of the prior art will be given below. Obviously, the accompanying drawings described below are only some embodiments described in this disclosure. For those of ordinary skill in the art, other drawings can also be obtained without any creative labor from these drawings. In the drawings:
In order to make those skilled in the art better understand the technical schemes in the present disclosure, the technical schemes in the embodiments of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of them. Based on the embodiments of the present disclosure, all other embodiments that are obtained by persons skilled in the art without making creative efforts shall fall within the protection scope of the present disclosure.
In the course of implementing the present application, the inventor of the present application discovers that, in the existing scheme of monitoring the charging temperature of the vehicle-mounted charging device of the new energy vehicle (such as a new energy vehicle-mounted charging socket), generally only one temperature sensor is provided to detect the vehicle-mounted charging device of the new energy vehicle. However, in many scenarios, there may be a case where the positive electrode connection terminal and the negative electrode connection terminal of the vehicle-mounted charging device of the new energy vehicle may possibly have different temperatures, and in addition, the charging temperature of the vehicle-mounted charging device of the new energy vehicle may also be affected by the external ambient temperature. In view of this, in order to improve the accuracy of measuring the charging temperature of the vehicle-mounted charging device of the new energy vehicle, the embodiment of the present application provides an improved temperature measurement circuit of the vehicle-mounted charging device of the new energy vehicle.
As shown in
The first temperature sensor TH1 is provided at a positive electrode connection terminal of the vehicle-mounted charging device of the new energy vehicle and is configured to acquire a first analog quantity temperature signal of the positive electrode connection terminal; the second temperature sensor TH2 is provided at a negative electrode connection terminal of the vehicle-mounted charging device of the new energy vehicle and is configured to acquire a second analog quantity temperature signal of the negative electrode connection terminal; the third temperature sensor TH3 is provided in a housing of the vehicle-mounted charging device of the new energy vehicle and can be far away from the position of a heating component, and is configured to acquire an analog quantity ambient temperature signal of the vehicle-mounted charging device of the new energy vehicle.
In view of in many scenarios, there may be a case where the positive electrode connection terminal and the negative electrode connection terminal of the vehicle-mounted charging device of the new energy vehicle may possibly have different temperatures, by providing temperature sensors respectively at the positive electrode connection terminal and the negative electrode connection terminal, the charging temperatures of the positive electrode connection terminal and the negative electrode connection terminal can be obtained correspondingly, which thus is conducive to obtaining a more accurate charging temperature of the vehicle-mounted charging device of the new energy vehicle. By providing the third temperature sensor TH3 in the housing of the vehicle-mounted charging device of the new energy vehicle and can be far away from the position of a heating component, which thus is conducive to obtaining more accurate ambient temperature. It should be noted that the ambient temperature here refers to the ambient temperature of the positive electrode connection terminal and the negative electrode connection terminal. In the embodiment of the present disclosure, the heating component is any component that may affect the positive electrode connection terminal and the negative electrode connection terminal. For example, in an exemplary embodiment, the heating component may include, for example, a microcontroller unit 20 of a temperature measurement circuit, etc.
In some embodiments, the above measures for locating the third temperature sensor TH3 away from the heating component may include:
For example, within the specified radius (for example, 1 cm) centered on the third temperature sensor: no components are placed on the front and back of the printed circuit board (that is, the PCB board), the PCB board is not covered with copper (two-layer or multi-layer boards), and/or PCB layout of the signal cable connected by the sensor including line width and line resistance are designed as recommended by the sensor manufacturer.
Although the third temperature sensor can be positioned as far away from the heating component as possible, due to limitation of practical conditions (such as the size of the vehicle-mounted charging device, etc.), the isolation distance may not achieve the desired effect. In this case, thermal insulation materials such as thermal insulation cotton or thermal insulation board and the like can be added as needed to avoid interference by the thermal radiation of the heating component.
For example, the third temperature sensor can be placed in a position where the external air flow of the printed circuit board is better (for example, the position near an external low-voltage signal connector on the printed circuit board and the like can be selected.
In some embodiments, the first temperature sensor TH1, the second temperature sensor TH2, and the third temperature sensor TH3 may be any suitable temperature sensor. For example, in an embodiment, the first temperature sensor TH1, the second temperature sensor TH2, and the third temperature sensor TH3 may also be a negative temperature coefficient (NTC) thermistor. In another embodiment, the first temperature sensor TH1, the second temperature sensor TH2, and the third temperature sensor TH3 may be a positive temperature coefficient (PTC) thermistor. In another embodiment, the first temperature sensor TH1, the second temperature sensor TH2, and the third temperature sensor TH3 may also be a thermocouple or an armored thermocouple and the like.
The analog-to-digital conversion module 10 is generally a multi-channel analog-to-digital conversion module, that is, it is capable to convert multiple analog signals into corresponding digital signals at the same time. The first temperature sensor TH1, the second temperature sensor TH2 and the third temperature sensor TH3 all output analog signals, and the microcontroller unit 20 can generally only recognize digital signals, therefore, so it is necessary to use the analog-to-digital conversion module 10 to convert the first analog quantity temperature signal into the first digital quantity temperature signal and to covert the second analog quantity temperature signal into the second digital quantity temperature signal correspondingly. In some embodiments, the microcontroller unit 20 itself may have a certain analog-to-digital conversion capability (for example, the microcontroller unit 20 has an analog-to-digital conversion circuit integrated therein), therefore, the analog quantity ambient temperature signal output by the third temperature sensor TH3 can be directly input to the analog-to-digital conversion circuit inside the microcontroller unit 20 for analog-to-digital conversion, so that the digital quantity ambient temperature signal can be obtained.
Of course, in other embodiments, the microcontroller unit 20 may also be selected as a microcontroller unit 20 without capability of analog-to-digital conversion. In this case, the analog-to-digital conversion module 10 should be capable to convert at least three analog signals into the corresponding digital signals at the same time, so that the first analog quantity temperature signal, the second analog quantity temperature signal and the analog quantity ambient temperature signal can be converted into the corresponding digital signals. In some other embodiments, the microcontroller unit 20 may also be selected as a microcontroller unit 20 with multi-channel analog-to-digital conversion capability, so that the first analog quantity temperature signal, the second analog quantity temperature signal and the analog quantity ambient temperature signal can be directly converted to the corresponding digital signals by utilizing the microcontroller unit 20. In this way, the analog-to-digital conversion module 10 is saved.

The microcontroller unit 20 can also be called a single-chip microcomputer, which is the control and processing center of the vehicle-mounted charging device of the new energy vehicle. In some embodiments, the microcontroller unit 20 can also be replaced by other control and processing chips such as a micro processor unit (MPU) and the like.
In the embodiment of the present disclosure, correcting the first digital quantity temperature signal and the second digital quantity temperature signal according to the digital quantity ambient temperature signal refers to correcting the first digital quantity temperature signal according to the digital quantity ambient temperature signal and correcting the second digital quantity temperature signal according to the digital quantity ambient temperature signal. In this way, the charging temperature of the positive electrode connection terminal and the charging temperature of the negative electrode connection terminal can be obtained considering the influence of ambient temperature, so that a more accurate charging temperature of the vehicle-mounted charging device of the new energy vehicle can be obtained.
Further, when either the positive electrode connection terminal charging temperature or the negative electrode connection terminal charging temperature reaches or exceeds the set temperature, the microcontroller unit 20 can accordingly perform safety control in time, so as to improve the charging safety and charging efficiency of the vehicle-mounted charging device of the new energy vehicle. Specifically, in the existing technology, if the acquired charging temperature is lower than the actual charging temperature, it is easy to cause high temperature of the vehicle-mounted charging device of the new energy vehicle; if the acquired charging temperature is higher than the actual charging temperature, it is easy to lead to the misoperation (for example, cutting off the charging circuit) of the vehicle-mounted charging device of the new energy vehicle, which will affect the charging efficiency. In the embodiment of the present disclosure, the temperature measurement circuit of the vehicle-mounted charging device of the new energy vehicle measures a more accurate charging temperature, thereby avoiding the misoperation or high temperature problem of the new energy vehicle-mounted charging socket caused by inaccurate charging temperature measurement in the prior art with a high probability, and thus improving the charging safety and charging efficiency of the vehicle-mounted charging device of the new energy vehicle.
In some embodiments, the correcting the first digital quantity temperature signal and the second digital quantity temperature signal according to the digital quantity ambient temperature signal, may include:
correcting the first digital quantity temperature signal according to the formula f(x1)=x1×(1+τx1)/(1+ax1); and correcting the second digital quantity temperature signal according to the formula f(x2)=x2×(1+τx2)/(1+ax2), where x1 denotes the first digital quantity temperature signal, x2 denotes the second digital quantity temperature signal, f(x1) denotes the corrected first digital quantity temperature signal, f(x2) denotes the corrected second digital quantity temperature signal, τ denotes a time constant, a denotes a temperature compensation coefficient, and a=(k1×z+b1)×τ+(k2×z+b2), k1 and b1 respectively denote slope and intercept of a straight line corresponding to the two temperature points when the temperature rises by one degree from the lower limit temperature at the specified current, k2 and b2 respectively denote slope and intercept of a straight line corresponding to the two temperature points when the temperature rises by one degree from the upper limit temperature at the specified current.
The specified current can be 500 A, 300 A, etc., which can be selected according to actual needs. The lower limit temperature and the upper limit temperature are both ambient temperatures, which can be determined according to the workable ambient temperature of the vehicle-mounted charging device of the new energy vehicle when implemented. For example, in an exemplary embodiment, the lower limit temperature may be −40° C. and the upper limit temperature may be 80° C. When the connection terminal is heated from −40° C. to −39° C. at the specified current, a straight line can be determined through the temperature point −40° C. and the temperature point −39° C. in the coordinate system of temperature change with time, and k1 and b1 can be obtained based on the straight line. By the same token, when the connection terminal is heated from 80° C. to 81° C. at the specified current, a straight line can be determined through the temperature point 80° C. and the temperature point 81° C. in the coordinate system of temperature change with time, and k2 and b2 can be obtained based on the straight line. In short, there is a linear correspondence between the temperature compensation coefficient a and the digital quantity ambient temperature signal z, and this correspondence can be stored in the form of a relationship curve. When correcting the first digital quantity temperature signal and the second digital quantity temperature signal according to the formula f(x)=x×(1+τx)/(1+ax), the corresponding temperature compensation coefficient a can be determined from the relationship curve through the actually measured ambient temperature.

The second bias circuit 32 can be provided on a line between the second temperature sensor TH2 and the analog-to-digital conversion module 10, which is configured to set a common mode voltage of the second temperature sensor TH2 within the specified voltage range of the second temperature sensor TH2 and detect whether the second temperature sensor TH2 has an open fault. That is, when the analog-to-digital conversion module 10 obtains a signal value that exceeds the specified voltage range of the first temperature sensor TH1, it can be recognized accordingly that the first temperature sensor TH1 has an open fault; when the analog-to-digital conversion module 10 obtains a signal value that exceeds the specified voltage range of the second temperature sensor TH2, it can be recognized accordingly that the second temperature sensor TH2 has an open fault, thus realizing the function of detection of the open fault. The specified voltage range described above can be determined according to the actually used performance parameters of the temperature sensor.
