The present disclosure relates generally to a vehicle technical field, more particularly to a battery connector, a battery module and an electric vehicle.
An electric vehicle uses a battery module as a power source to supply electricity for operation. In related art, battery modules of the electric vehicle are connected with each other via fuse devices. When the fault of a control circuit occurs, the fuse device could sever the connection between the battery modules timely so as to cut off the power source to avoid accidents. However, there is no any arc extinguishing measure applied to the traditional fuse. When the fuse melts, an electric arc may generate, and the electric arc may breakdown the battery to cause risks of burning and explosion, thus threatening safety of passengers. In addition, since there is no shell to support the fuse, a crack may occur at a weakest portion of the fuse, and then a safety performance and reliability of the battery module may be decreased.

A battery connector 1 for an electric vehicle according to embodiments of the present disclosure will be described with reference to
As shown in
Specifically, the connecting sheet 10 has a fusing portion 13, and a cross sectional area of the fusing portion 13 is less than a cross sectional area of rest part of the connecting sheet 10. When an overcurrent or short circuit current passes through the fusing portion 13, the fusing portion 13 itself generates heat and melts, such that the connecting sheet 10 will be disconnected to protect the battery. When a fault occurs to a control circuit, the fusing portion would melt so as to disconnect two adjacent batteries.
A cross section of the fusing portion 13 is obtained by cutting the fusing portion 13 along a width direction of the fusing portion 13. Specifically, a front-rear direction shown in
The fusing portion 13 is encased in the protective component 20. Then, an electric arc generated during melting of the fusing portion 13 would be limited within the protective component 20, and the electric arc would be extinguished quickly, so as to avoid destroying other portions of the connecting sheet 10, therefore preventing breakdown of the battery and avoiding an explosion of the battery. It should be noted that, “the fusing portion 13 is encased in the protective component 20” may be that an inner surface of the protective component 20 and a surface of the fusing portion 13 are closely fitted with each other, or that the inner surface of the protective component 20 defines a protective chamber 24 and the fusing portion 13 is disposed within the protective chamber 24.
During operation of an electric vehicle, the battery connector 1 may be continuously shaking, and since the cross sectional area of the fusing portion 13 is less than the cross sectional area of the rest part of the connecting sheet 10, the fusing portion 13 may be easily broken due to the continuously shaking, as compared with the rest part of the connecting sheet 10. In some embodiments, the protective component 20 is connected to portions of the connecting sheet 10 adjacent to two ends of the fusing portion 13, and thus the protective component 20 may act as a supporting casing for the fusing portion 13 to increase a connection reliability of the fusing portion 13, thus improving a reliability of the connecting sheet 10.
With the battery connector 1 according to embodiments of the present disclosure, the fusing portion 13 having the cross sectional area less than that of the rest part of the connecting sheet 10 is disposed to the connecting sheet 10, and the fusing portion 13 is encased in the protective component 20, such that connection between batteries can be realized, and when a fault occurs to the control circuit, the connection between batteries can be cut off timely, so as to protect the battery. Moreover, the electric arc generated due to the melting of the fusing portion 13 can be extinguished quickly to avoid breaking down the battery, thus decreasing the risks of burning and explosion, and reducing safety hazards on passengers. In addition, the protective component 20 can improve a connection reliability of the fusing portion 13 and prevent the fusing portion 13 from being broken due to the shaking of the battery connector 1.
In some embodiments of the present disclosure, as shown in

For example, as shown in
In one embodiment, as shown in
In some embodiments of the present disclosure, the fusing portion 13 has at least one through-hole 131, such that the electric arc generated during the melting can be divided into several small electric arcs, and thus the power of the electric arc is reduced, which facilitates quick extinguishing of the electric arc. In some embodiments of the present disclosure, as shown in

In another example, directions of mounting the first magnetic member 23 and the second magnetic member are the same as stated above, that is, both of upper ends of the first magnetic member 23 and the second magnetic member are N poles, and both of lower ends of the first magnetic member 23 and the second magnetic member are S poles. If the direction of current passing through the fusing portion 13 points to right (i.e., right as shown in
In some other embodiments of the present disclosure, both of upper ends of the first magnetic member 23 and the second magnetic member are S poles, and both of lower ends of the first magnetic member 23 and the second magnetic member are N poles. As shown in
An installation direction of the battery connector 1 is related to a polarity relationship (i.e., N-S directions) of the first magnetic member 23 and the second magnetic member 23, and also to the opening direction of the concave portion 14. It should be noted that there is no particular limitation to the mounting positions of the first magnetic member 23 and the second magnetic member 23, the polarity relationship (i.e., the N-S directions) of the first magnetic member 23 and the second magnetic member 23, the current direction and the opening direction of the concave portion 14, as long as the electric arc generated during the melting of the fusing portion 13 can be pulled toward the concave portion 14 under the force applied to the electric arc in the magnetic field according to left hand rule.
In some embodiments of the present disclosure, as shown in
In some embodiments, the first shell 21 and the second shell 22 are connected via snap-fit. Specifically, the first shell 21 includes a protrusion and/or a slot formed on a first joint surface thereof fitted with the second shell 22, the second shell 22 includes a slot and/or a protrusion formed on a second joint surface thereof fitted with the first shell 21, and the slot and/or the protrusion formed on the second joint surface of the second shell 22 is or are fitted with the protrusion and/or the slot formed on the first joint surface of the first shell 21.
For example, the first shell 21 includes at least one protrusion formed on the first joint surface thereof, the second shell 22 includes at least one slot formed on the second joint surface thereof, and the at least one protrusion is fitted with the at least one slot. For another example, the first shell 21 includes at least one slot formed on the first joint surface thereof, the second shell 22 includes at least one protrusion formed on the second joint surface thereof, and the at least one slot is fitted with the at least one protrusion. In some other examples, the first shell 21 includes at least one protrusion and at least one slot formed on the first joint surface thereof, the second shell 22 includes at least one slot and at least one protrusion formed on the second joint surface thereof, and the at least one protrusion on the first joint surface is fitted with the at least one slot on the second joint surface, and the at least one slot on the first joint surface is fitted with the at least one protrusion on the second joint surface.
In some embodiments of the present disclosure, as shown in
In some embodiments, as shown in
In some other embodiments of the present disclosure, the first shell 21 and the second shell 22 are welded together. Specifically, a brazing layer (not shown) is disposed between the joint surfaces of the first shell 21 and the second shell 22, and the first shell 21 and the second shell 22 are welded together via the brazing layer so as to define the protective chamber 24. Thus, a sealed protective chamber 24 is formed, and the electric arc generated during the melting of the fusing portion 13 can be isolated from outside air so as to effectively increase an extinguishing speed of the electric arc. It should be noted that, the brazing layer is disposed on at least one of the joint surfaces of the first shell 21 and the second shell 22, and the brazing layer may be melt in a brazing furnace. Under a high temperature, the brazing layers on the first joint surface and the second joint surface 221 are melt, such that the first joint surface and the second joint surface 221 are welded together, and thus the fusing portion 13 is sealed in the protective chamber 24.
In some embodiments of the present disclosure, the protective chamber 24 is filled with hydrogen. Hydrogen not only can take away plenty of heat and decrease a temperature in an arc zone, but also can blow away ionized gas to fill the protective chamber 24 with fresh high-pressure gas, such that an extinguishing speed of the electric arc is increased and an extinguishing effect thereof is improved. In some embodiments, as shown in
In some embodiments of the present disclosure, the first shell 21 and the second shell 22 are made of insulating, anti-flame and high-temperature resistant non-metal materials. Thus, the fusing portion 13 can be isolated from other portions of the connecting sheet 10 to avoid destroying the other portions of the connecting sheet 10 when the electric arc generated during the melting of the fusing portion 13 is extinguished. In one embodiment, the first shell 21 and the second shell 22 are made of ceramic. Ceramic material has rich sources and a low cost, and the ceramic process is mature, such that the cost can be reduced and the production cycle can be shortened.
In some embodiments, the first connecting portion 11, the second connecting portion 12 and the fusing portion 13 are integrally molded. Thus, s structure of the battery connector 1 can be simplified, the production cycle can be shortened, and the cost can be reduced. It should be noted that, there are no particular limitations to the manufacturing method of integrally molding the first connecting portion 11, the second connecting portion 12 and the fusing portion 13. For example, the first connecting portion 11, the second connecting portion 12 and the fusing portion 13 may be integrally molded via impact molding. In some embodiments, the first connecting portion 11, the second connecting portion 12 and the fusing portion 13 are made of metal materials. The metal material has a good conductivity performance, which may be beneficial for the connection between batteries. It should be noted that, there is no particular limitation to the metal materials of the first connecting portion 11, the second connecting portion 12 and the fusing portion 13. For example, the metal material may be copper, silver, tin, or alloys thereof.
In some embodiments of the present disclosure, the protective component 20 is connected to portions of the connecting sheet 10 adjacent to two ends of the fusing portion 13. Thus, the whole fusing portion 13 may be disposed within the protective component 20, such that the other portions of the connecting sheet 10 can be prevented from being destroyed by the electric arc generated during the melting of the fusing portion 13, and the connecting sheet 10 can be protected well. It should be noted that, during operation of the electric vehicle, for example, when the electric vehicle runs on a road, the battery connector 1 may be continuously shaking, and since the cross sectional area of the fusing portion 13 is less than the cross sectional areas of the other portions of the connecting sheet 10, the fusing portion 13 may be more easily broken due to continuously shaking, as compared with the other portions of the connecting sheet 10. In some embodiments, the protective component 20 is connected to the portions of the connecting sheet 10 adjacent to two ends of the fusing portion 13, and thus the protective component 20 can act as a supporting housing for the fusing portion 13 to increase a connection reliability of the fusing portion 13, so as to improve a reliability of the connecting sheet 10.
In some embodiments, a surface of the protective component 20 fitted with the connecting sheet 10 is configured as a metalized surface, and the metalized surface is fixed to the connecting sheet 10 via welding. It should be noted that the protective component 20 and the connecting sheet 10 are closely fitted with each other, and under a high temperature, the metal on surfaces of the protective component 20 and the connecting sheet 10 begins to melt, and after being cooled down, the surfaces of the protective component 20 and the connecting sheet 10 are welded together, i.e., the protective component 20 and the connecting sheet 10 are welded together. Thus, the other portions of the connecting sheet 10 can be prevented from being destroyed by the electric arc generated during the melting of the fusing portion 13, and the protective component 20 can act as the supporting member for the fusing portion 13 to increase the connection reliability of the fusing portion 13, so as to improve the reliability and safety of the connecting sheet 10.
According to embodiments of the present disclosure, the battery connector 1 for an electric vehicle includes a connecting sheet 10 and a protective component 20.
Specifically, the connecting sheet 10 has a fusing portion 13, and a cross sectional area of the fusing portion 13 is less than a cross sectional area of rest part of the connecting sheet 10. When an overcurrent or short circuit current passes through the fusing portion 13, the fusing portion 13 will generate heat and begin to melt, such that the connecting sheet will be disconnected to protect batteries. Therefore, when a control circuit has a fault, the fusing portion 13 may melt so as to disconnect two batteries.
The protective component 20 includes a first shell 21 and a second shell 22, the first shell 21 and the second shell 22 define a sealed protective chamber 24 therebetween, and the fusing portion 13 is disposed in the protective chamber 24. A surface of the protective component 20 matched with connecting sheet 10 is configured as a metalized surface, i.e., joint surfaces of the first shell 21 and the second shell 22 are configured as metalized surfaces, and the metalized surfaces of the first shell 21 and the second shell 22 are respectively welded to portions of the connecting sheet 10 adjacent to two ends of the fusing portion 13. Then, other portions of the connecting sheet 10 can be prevented from being destroyed by the electric arc generated during the melting of the fusing portion 13, and the protective component 20 can act as a supporting housing for the fusing portion 13 to increase a connection reliability of the fusing portion 13, so as to improve reliability and safety of the connecting sheet 10.
For example, a surface of the first shell 21 facing and connected to the second shell 22, and a surface of the second shell 22 facing and connected to the first shell 21 are joint surfaces. These joint surfaces are configured as metalized surfaces. The connecting sheet 10 includes a first connecting portion 11 and a second connecting portion 12, and the fusing portion 13 is disposed between the first connecting portion 11 and the second connecting portion 12. An end of the first connecting portion 11 connected to the fusing portion 13 is welded to the metalized surfaces of the first shell 21 and the second shell 22 respectively, and an end of the second connecting portion 12 connected to the fusing portion 13 is also welded to the metalized surfaces of the first shell 21 and the second shell 22 respectively. Furthermore, the first shell 21 and the second shell 22 may be welded together through the metalized surfaces thereof. Thus, the other portions of the connecting sheet 10 can be prevented from being destroyed by the electric arc generated during the melting of the fusing portion 13 to increase the connection reliability of the fusing portion 13, so as to improve the reliability and safety of the connecting sheet 10.
With the battery connector 1 according to embodiments of the present disclosure, the fusing portion 13 having the cross sectional area less than that of the rest part of the connecting sheet 10 is disposed to the connecting sheet 10, and the fusing portion 13 is encased in the protective component 20, specifically in the protective chamber 24 defined by the first shell 21 and the second shell 22, such that connection between batteries can be realized, and when the control circuit has a fault, the connection between batteries can be cut off timely, so as to protect the batteries. Moreover, the electric arc generated due to the melting can be extinguished quickly to prevent the battery from being broken-down by the electric arc, thus reducing the risks of burning and explosion, and avoiding safety hazards on passengers.
In addition, the joint surfaces of the first shell 21 and the second shell 22 are metalized, and the metalized surfaces of the first shell 21 and the second shell 22 are fixed to the portions of the connecting sheet 10 adjacent to the fusing portion 13 via welding. Thus, the protective component 20 can act as the supporting housing for the fusing portion 13 to increase the connection reliability of the fusing portion 13, so as to improve the reliability of the connecting sheet 10.
The battery connector 1 according to embodiments of the present disclosure will be described with reference to
As shown in
As shown in
In addition, the fusing portion 13 has a through-hole 131 formed therein, such that the electric arc generated during the melting may be divided into several smaller electric arcs, the power of the electric arc can be reduced, and thus the electric arc can be extinguished quickly. The fusing portion 13 further includes two grooves 134 formed therein, and the two grooves 134 are symmetrically formed at two sides of the through-hole 131. An opening of one groove 134 faces away from the concave portion 14, and an opening of the other groove 134 faces the concave portion 14. Thus, not only the electric arc generated during the melting can be divided into several small electric arcs, but also can the width of the fusing portion 13 be further decreased, so as to make sure that the fusing portion 13 can melt when the control circuit has a fault. Thus, the reliability and safety of the battery connector 1 may be further improved.
As shown in
Both an upper end of the first magnetic member 23 (an end surface of the first magnetic member 23 facing the connecting sheet 10 as shown in
In addition, as shown in
In addition, in the left-right direction as shown in
It should be noted that, a surface of the first shell 21 facing and connected to the second shell 22 is the first joint surface, and a surface of the second shell 22 facing and connected to the first shell 21 is the second joint surface 221.
In addition, the first shell 21 and the second shell 22 are made of insulating, anti-flame and high-temperature resistant non-metal materials, and at least part of the first joint surface and at least part of the second joint surface 221 (for example, end parts of the first and second joint surfaces) are metalized. For example, a brazing layer is disposed on at least one of the at least part of the first joint surface and the at least part of the second joint surface 221. The first connecting portion 11, the second connecting portion 12 and the fusing portion 13 may be integrally molded via impact molding, and the first connecting portion 11, the second connecting portion 12 and the fusing portion 13 are made of metal materials, such as copper, tin.
An end part of the first connecting portion 11 connected to the fusing portion 13 is fitted and welded with the first joint surface of the first shell 21 and the second joint surface of the second shell 22 respectively, and an end part of the second connecting portion 12 connected to the fusing portion 13 is fitted and welded with the first joint surface of the first shell 21 and the second joint surface of the second shell 22 respectively. Under a high temperature, metal on the metalized surface begins to melt, then the first connecting portion 11 is welded to the first joint surface and the second joint surface respectively, and the second connecting portion 12 is welded to the first joint surface and the second joint surface respectively. Therefore, the fusing portion 13 can be limited within the sealed protective chamber 24 defined by the first shell 21 and the second shell 22. Thus, the electric arc generated during the melting can be isolated in the protective chamber to prevent other portions of the connecting sheet 10 from being destroyed by the electric arc. And, the protective component 20 can act as a supporting housing for the fusing portion 13 to improve the connection reliability of the fusing portion 13, so as to increase the reliability of the connecting sheet 10, thus preventing the fusing portion 13 from being broken due to the frequent shaking during operation of the electric vehicle.
In some other embodiments of the present disclosure, the whole first joint surface and the whole second joint surface 221 are metalized, such that the first joint surface of the first shell 21 and the second joint surface 221 of the second shell 22 can be fitted and welded with each other. That is, the first shell 21 and the second shell 22 are connected to each other via welding. In such case, under a high temperature, metal of the metalized surface begins to melt, then the first connecting portion 11 is welded to the first joint surface and the second joint surface respectively, the second connecting portion 12 is welded to the first joint surface and the second joint surface respectively, and at the same time, the first joint surface is welded to the second joint surface. Therefore, the fusing portion 13 can be limited within the sealed protective chamber 24 defined by the first shell 21 and the second shell 22.
The protective chamber 24 may be filled with hydrogen. Hydrogen not only can take away plenty of heat and decrease a temperature in an arc zone, but also can blow away ionized gas to fill the protective chamber 24 with fresh high-pressure gas, thus increasing an extinguishing speed of the electric arc and improving an extinguishing effect thereof. A gas inlet 25 is formed in the first shell 21 and a duct 26 is inserted in the gas inlet 25 to fill hydrogen into the protective chamber 24. When the protective chamber 24 is full of hydrogen, the duct 26 is cut off, compacted and sealed.

Moreover, an electric arc generated due to the melting can be extinguished quickly to prevent the battery from being broken down by the electric arc, thus reducing the risks of burning and explosion, and avoiding safety hazards on passengers. In addition, the protective component 20 can act as a supporting housing for the fusing portion 13 to improve the connection reliability of the fusing portion 13, so as to increase the reliability of the connecting sheet 10.
