[0029] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0030] Reference below Figure 1-Figure 5 A battery pack 1 according to an embodiment of the present invention is described.

[0031] like Figure 1-Figure 5 As shown, the battery pack 1 according to the embodiment of the utility model includes: a box 10, a battery 20, a domain control module and a control component. The box 10 is a structural member for placing the battery 20, and the battery 20 can be set in the box 10, so as to protect the battery 20. The battery 20 is the main part of the battery pack 1 and can provide energy for external devices. The domain control module is a regional control module, and the control component can play a control role.

[0032] The domain control module includes: a first electric control module and a second electric control module, both of which are arranged in the box 10, and the first electric control module and the second electric control module are arranged at intervals. In other words, the electric control module is divided into a first electric control module and a second electric control module, and the first electric control module and the second electric control module are arranged at intervals. The first electric control module and the second electric control module can be controlled at different positions, so that partition control can be performed, and the integration of the battery pack 1 can be improved, and the sealing and mounting structures of the control components on the vehicle can be reduced. In this way, the number of components can be reduced, and the space occupied by the components can be reduced, and the overall production cost of the vehicle can be reduced, and the weight of the vehicle can be reduced.

[0033] In an optional embodiment, the first electric control module is arranged at the front end of the box 10, and the second electric control module is located behind the first electric control module. That is to say, the first electric control module is arranged at the front end of the box 10, and the second electric control module is arranged inside the box 10, so that the first electric control module and the second electric control module can be separated, and the arrangement of the first electric control module and the second electric control module on the box 10 is convenient. Among them, the second electric control module can be arranged inside the box 10, and can also be arranged at the rear end of the box 10.

[0034] Among them, Figure 3 and Figure 4 As shown, the box body 10 includes: a front side beam 11, the front side beam 11 is provided with a receiving cavity 12, the compressor controller 50 is arranged in the receiving cavity 12, the first electric control module includes: a compressor controller 50 or a front motor controller 60, the compressor controller 50 or the front motor controller 60 is arranged in the receiving cavity 12, or the first electric control module includes: a compressor controller 50 and a front motor controller 60, the compressor controller 50 and the front motor controller 60 are both arranged in the receiving cavity 12, and the front motor controller 60 is arranged at intervals from the compressor controller 50. That is to say, the first electric control module may include any one of the compressor controller 50 and the front motor controller 60, and may also include the compressor controller 50 and the front motor controller 60 at the same time.

[0035] Specifically, the front side beam 11 is located at the front end of the box body 10, and can play a supporting and protective role at the front end of the box body 10. The front side beam 11 is provided with a receiving cavity 12, which can play a role of receiving and placing. The compressor controller 50 is arranged in the receiving cavity 12, so that the compressor controller 50 can be better installed and fixed, so that the setting of the compressor controller 50 can be made more stable and reliable. Moreover, the compressor controller 50 is located at the front end of the box body 10, which is convenient for external devices to obtain power through the compressor controller 50.

[0036] The front motor controller 60 is arranged in the accommodating chamber 12, and the front motor controller 60 is arranged at a distance from the compressor controller 50. The front motor controller 60 is arranged in the accommodating chamber 12, so that the front motor controller 60 can be better installed and fixed, so that the setting of the front motor controller 60 can be more stable and reliable, and the front motor controller 60 is located at the front end of the box body 10, which is also convenient for external devices to draw power through the front motor controller 60. The front motor controller 60 is arranged at a distance from the compressor controller 50, so that interference between the front motor controller 60 and the compressor controller 50 can be avoided, which affects the normal operation of the front motor controller 60 and the compressor controller 50.

[0037] The second electric control module includes: a power distribution module 30 and a vehicle charger 40. The power distribution module 30 can distribute power and output appropriate electric energy for corresponding devices. The vehicle charger 40 can be used to charge electronic devices, such as mobile phones and other digital products, so that users can charge electronic devices in the car. The control component can play a corresponding control role.

[0038] The power distribution module 30, the on-board charger 40 and the compressor controller 50 are electrically connected to the battery 20, respectively. It can be understood that the power distribution module 30 is electrically connected to the battery 20, so that the electric energy in the battery 20 can be input to the power distribution module 30, and then the power distribution module 30 is adjusted and distributed to output the corresponding electric energy for the corresponding device. The on-board charger 40 is electrically connected to the battery 20, so that the electric energy in the battery 20 can be input to the on-board charger 40, so that it can be used to charge electronic equipment. The compressor controller 50 is electrically connected to the battery 20, so that the electric energy in the battery 20 powers the compressor controller 50, so that the operation of the compressor controller 50 can be controlled according to demand.

[0039] Furthermore, the first electric control module further includes: a thermistor, which is integrated into the compressor controller 50. The resistance value of the thermistor can increase stepwise as the temperature increases, and can protect the circuit when the current surge is too large or the temperature is too high. Integrating the thermistor into the compressor controller 50 can further improve the integration of the battery pack 1.

[0040] Of course, if Figure 4As shown, the first electric control module also includes: a cooling module 70, which is arranged in the accommodating chamber 12 to cool the compressor controller 50, the front motor controller 60 and the thermistor. The cooling module 70 is arranged in the accommodating chamber 12, so that the cooling module 70 can be better installed and fixed, so that the setting of the cooling module 70 can be more stable and reliable. In addition, in this way, the cooling module 70 is closer to the compressor controller 50, the front motor controller 60 and the thermistor, so that the compressor controller 50, the front motor controller 60 and the thermistor can be effectively dissipated. In addition, compared with relying on air heat dissipation, this setting can further improve the heat dissipation efficiency, thereby further reducing the ambient temperature at the compressor controller 50 and the front motor controller 60, avoiding the compressor controller 50 and the front motor controller 60 from being damaged due to excessive heat, and thus improving the yield of the battery pack 1.

[0041] According to an optional embodiment of the present utility model, Figure 4 As shown, the first electric control module also includes: a plug-in board 80, a mounting port 13 is provided at the accommodating chamber 12, the plug-in board 80 is detachably provided at the mounting port 13, and the compressor controller 50, the front motor controller 60 and the thermistor are electrically connected to the plug-in board 80 respectively. The compressor controller 50, the front motor controller 60 and the thermistor are electrically connected to the plug-in board 80 respectively, so that the external device can be plugged and matched with the plug-in board 80, so as to facilitate external power supply. Moreover, the mounting port 13 is provided at the accommodating chamber 12, and after the compressor controller 50, the front motor controller 60, the thermistor and the cooling module 70 are arranged in the accommodating chamber 12, the plug-in board 80 can be installed at the mounting port 13, so that a certain sealing effect can be achieved to prevent the external environment from affecting the compressor controller 50, the front motor controller 60, the thermistor and the cooling module 70. Of course, the plug board 80 can also be removed from the installation opening 13, so that the plug board 80 can be used as a repair panel. When the compressor controller 50, the front motor controller 60, the thermistor and the cooling module 70 are damaged, the plug board 80 can be opened, and the compressor controller 50, the front motor controller 60, the thermistor and the cooling module 70 in the accommodating cavity 12 can be repaired or replaced through the installation opening 13. It should be noted that a first electric control module can be formed between the compressor controller 50, the front motor controller 60, the thermistor, the cooling module 70 and the plug board 80, and the specific setting positions of the compressor controller 50, the front motor controller 60, the thermistor and the cooling module 70 can be set according to actual working conditions.

[0042] It should be noted that if Figure 4As shown, the front side beam 11 is an integral die-cast structural member. In other words, the front side beam 11 is formed by an integral die-casting process, and the integral die-casting process is simple, and through a highly integrated design, it can reduce unnecessary welding, gluing and other processes, and at the same time, it can eliminate the possible risks of air tightness, improve the product yield of the battery pack 1, and reduce the production cost of the battery pack 1.

[0043] In addition, if Figure 5 As shown, the battery pack 1 further includes: a mounting seat 90, which is spaced apart behind the front side beam 11, and the second electric control module further includes: a rear motor controller 100, and the power distribution module 30, the on-board charger 40 and the rear motor controller 100 are spaced apart on the mounting seat 90. The mounting seat 90 can play a role in installation and fixing, and the mounting seat 90 is spaced apart behind the front side beam 11, for example, it can be set in the middle position of the box body 10, or it can be set at one end of the box body 10 away from the front side beam 11, and its specific position can be determined according to the vehicle model. The power distribution module 30, the on-board charger 40 and the rear motor controller 100 are arranged at intervals, so that interference between the power distribution module 30, the on-board charger 40 and the rear motor controller 100 can be avoided, thereby affecting the normal operation of the power distribution module 30, the on-board charger 40 and the rear motor controller 100. The power distribution module 30, the on-board charger 40 and the rear motor controller 100 are all arranged on the mounting seat 90, so that the integration of the battery pack 1 can be improved, and the length of the connector between the power distribution module 30, the on-board charger 40 and the rear motor controller 100 can be effectively shortened. It should be noted that a second electric control module can be formed between the power distribution module 30, the on-board charger 40 and the rear motor controller 100.

[0044] It should be noted that the battery 20 is electrically connected to the power distribution module 30, the on-board charger 40 and the rear motor controller 100 on the mounting seat 90, and then a connecting wire is provided, one end of the connecting wire is electrically connected to the power distribution module 30, the on-board charger 40 and the rear motor controller 100 respectively, and the other end of the connecting wire is electrically connected to the compressor controller 50, the front motor controller 60 and the thermistor respectively. In this way, the compressor controller 50, the front motor controller 60 and the thermistor are arranged in the accommodating cavity 12 of the front side beam 11, which can also reduce the space occupied between the first electronic control module and the second electronic control module, and can effectively increase the space utilization rate in the battery pack 1, ensuring that more batteries 20 are arranged in a limited space, thereby increasing the energy density of the battery pack 1.

[0045] In addition, if the battery pack 1 is only provided with the second electronic control module, and the compressor controller 50, the front motor controller 60 and the thermistor are not integrated in the accommodating cavity 12 of the front side beam 11, then the compressor controller 50, the front motor controller 60 and the thermistor need to be connected to the second electronic control module by connecting wires, which will increase the number of wires in the battery pack 1 and make the wiring harness layout in the battery pack 1 more complicated. In this way, in the present application, the number of wires in the battery pack 1 can be reduced and the wiring harness layout in the battery pack 1 can be simplified.

[0046] Alternatively, if Figure 2 and Figure 3 As shown, the battery pack 1 also includes: a cover plate 110, the cover plate 110 is covered on the box body 10, and a maintenance port 111 is opened on the cover plate 110, and the maintenance port 111 is arranged opposite to the mounting seat 90. The cover plate 110 can play a role of covering and sealing. The cover plate 110 is covered on the box body 10, so that the external environment can be prevented from affecting the components inside the box body 10. A maintenance port 111 is opened on the cover plate 110, and the maintenance port 111 is arranged opposite to the mounting seat 90, so that the power distribution module 30, the vehicle charger 40 and the rear motor controller 100 on the mounting seat 90 can be quickly repaired and replaced through the maintenance port 111, and the operation is simpler and more convenient.

[0047] Of course, if Figure 2 and Figure 3 As shown, the battery pack 1 also includes: a maintenance plate 120, which is detachably arranged at the maintenance port 111. It should be noted that the maintenance plate 120 can be assembled with the cover plate 110 in a detachable form such as a rubber ring and a bolt. When the maintenance plate 120 is installed at the maintenance port 111, it can play a certain sealing role to prevent the external environment from affecting the components inside the box body 10. Of course, the maintenance plate 120 can also be removed from the maintenance port 111, so that the power distribution module 30, the vehicle charger 40 and the rear motor controller 100 on the mounting seat 90 can be quickly repaired and replaced directly through the maintenance port 111 without disassembling the entire cover plate 110. In addition, the maintenance plate 120 has a simple structure and is easy to operate.

[0048] In addition, Figure 2 As shown, the box body 10 also includes: a protective beam 14, which is suitable for defining a placement space between the batteries 20, and the mounting seat 90 is arranged in the placement space. The protective beam 14 can play a supporting and protective role, making the overall structure of the battery pack 1 more stable and reliable. The protective beam 14 can define a placement space between the batteries 20, which is convenient for the installation and placement of the mounting seat 90, and can separate the batteries 20 from the mounting seat 90 to avoid interference between the batteries 20 and the devices on the mounting seat 90.

[0049] It should be noted that, in addition to the front side beam 11, the box body 10 is also provided with some other side beams. The front side beam 11, the protection beam 14 and the other side beams together provide mechanical protection for the battery 20, the first electronic control module and the second electronic control module. In addition, the bottom guard plate of the battery pack 1 can provide mechanical protection for the entire box body 10. Among them, the protection beam 14 and the other side beams can adopt structures with similar stiffness and adopt extrusion technology, which is low-cost and has better structural strength.
