[0047] It should be noted that, Figures 1 to 6The schematic diagram of the battery energy distribution unit, the battery pack and the components in the vehicle is shown, and the specific structure of the battery energy distribution unit, the battery pack and the remaining components in the vehicle is not limited to Figures 1 to 6 The example.

[0048] The present application will be described in detail below in conjunction with the drawings and specific embodiments:

[0049] Referring to Figures 1 to 4 The embodiment of the present application provides a battery energy distribution unit, which is arranged in a battery pack and comprises a shell 100, an electronic device assembly 200, a control board 300 and at least one connecting assembly 600.

[0050] The electronic device assembly 200 is electrically connected with a high-voltage circuit and a low-voltage control circuit. The shell 100 has a mounting cavity, and the electronic device assembly 200 is arranged in the mounting cavity.

[0051] The control board 300 is arranged in the mounting cavity, and the electronic device assembly 200 is inserted on the control board 300 through the connecting assembly 600 and is electrically connected with the control board 300.

[0052] The control board 300 is used for a battery management system to monitor the state parameters of the battery pack, and the control board 300 is also used for controlling the opening and closing of the high-voltage circuit and the low-voltage control circuit through the electronic device assembly 200.

[0053] Through the above arrangement, the battery management system can be integrated into the battery energy distribution unit, the functions are concentrated, and the overall installation is facilitated.

[0054] The battery management system (Battery Manangement System) is also called BMS, which is used for intelligently managing and maintaining each battery unit, monitoring the state of the battery, preventing overcharging and overdischarging of the battery, and prolonging the service life of the battery.

[0055] The battery energy distribution unit (Battery energy Distribution Unit) is also called BDU, which controls the power-on and power-off process, the pre-charging process and the charging process of the high-voltage circuit. Whether the characteristic parameters of the BDU product meet the qualified conditions has an important influence on the service life, the control strategy and the high-voltage safety of the vehicle.

[0056] In the above embodiment, by integrating the BMS and the BDU, a BDMU (Battery energy Distribution Manangement Unit) with the BMS function is formed.

[0057] And by setting the connecting assembly 600, the electronic component assembly 200 is plugged with the control panel 300, so that the wire harness for electrically connecting the electronic component assembly 200 and the control panel 300 can be omitted, the assembly of the electronic component assembly 200 and the control panel 300 is facilitated, and during later maintenance, due to the omission of the wire harness, the effect of convenient maintenance is achieved.

[0058] In a possible implementation, the bottom wall of the shell 100 is used to connect with the top surface of the cold plate 500 of the battery pack. In the related art, the battery pack has a plurality of battery cells (not shown in the figure), and the battery cells generate a large amount of heat during operation. In order to dissipate the heat of the battery cells in time, the cold plate 500 is laid at the bottom of the battery pack. The cold plate 500 can effectively remove the heat of the battery cells through physical contact, so that the battery cells can maintain a suitable working temperature. The specific structure of the cold plate 500 is not limited in the embodiments of the application.

[0059] The shell 100 is cooled by the cold plate 500 provided in the battery pack, which is equivalent to cooling the battery energy distribution unit and the battery management system at the same time, and indirectly cooling the electronic component assembly 200 and the control panel 300. Compared with the traditional cooling method using a cooling copper bar, the cooling efficiency is improved, and the cooling performance of the battery energy distribution unit and the battery management system is improved.

[0060] In a possible implementation, in order to facilitate the processing and assembly of the shell 100, the shell 100 includes a first shell 110 and a second shell 120.

[0061] The first shell 110 is connected with the cold plate 500, and the second shell 120 is arranged on the first shell 110. The first shell 110 and the second shell 120 jointly define the mounting cavity.

[0062] The control panel 300 is arranged in the first shell 110.

[0063] In this way, by arranging the first shell 110 and the second shell 120 in a cover arrangement, the mounting cavity can be conveniently opened and closed, and the installation and maintenance of the parts inside the mounting cavity are facilitated, and the installation efficiency of the shell 100 is improved.

[0064] One of the first shell 110 and the second shell 120 has at least one first clamping piece 111, and the other has at least one second clamping piece 121.

[0065] The first clamping piece 111 and the second clamping piece 121 are one-to-one correspondingly clamped.

[0066] In this way, through the clamping of the first clamping piece 111 and the second clamping piece 121, the detachable connection of the first shell 110 and the second shell 120 can be quickly achieved, and the assembly efficiency of the shell 100 is improved. In a specific implementation, one of the first clamping piece 111 and the second clamping piece 121 is a clamping ring, and the other is a clamping head, which is inserted into the clamping ring. Of course, here it can also be another form of one-to-one corresponding clamping of the first clamping piece 111 and the second clamping piece 121, and the present application does not limit this.

[0067] In one possible implementation, referring to FIGS. 1-2, Figure 2 and Figure 3 The electronic device assembly 200 includes at least one of a main positive relay 210 and a main negative relay 220.

[0068] The main positive relay 210 and the main negative relay 220 each have at least one plug-in piece 230.

[0069] The connection assembly 600 is connected to the control panel 300, and the plug-in piece 230 is used to be inserted into the connection assembly 600, so that the main positive relay 210 and the main negative relay 220 are electrically connected to the control panel 300.

[0070] In a specific implementation, the connection assembly 600 includes a connection part 610 connected to the control panel 300 and a clamping part 620 provided on the connection part 610. In the related technical field, the connection part 610 can be electrically connected to the control panel 300 by welding. The clamping part 620 includes at least two oppositely arranged elastic sheets 621, and the plug-in piece 230 can be inserted between the two elastic sheets 621. On the one hand, the plug-in piece 230 can be electrically connected to the control panel 300 through the elastic sheet 621 and the connection part 610. On the other hand, the two oppositely arranged elastic sheets 621 can tightly clamp the plug-in piece 230, thereby improving the connection accuracy and stability.

[0071] Of course, in order to improve the connection stability, the number of plug-in pieces 230 on the main positive relay 210 and the main negative relay 220 is set to at least two, and the connection assembly 600 corresponds to each plug-in piece 230.

[0072] In the above embodiment, the main positive relay 210 and the main negative relay 220 are related technologies in the field, and the positive relay and the main negative relay 220 are electrically connected with the high-voltage circuit and the low-voltage control circuit to control the opening and closing of the high-voltage circuit and the low-voltage control circuit. The connecting assembly 600 is arranged on the control panel 300, and the main positive relay 210 and the main negative relay 220 are plugged with the connecting assembly 600 through the plug-in part 230, so that the main positive relay 210 and the main negative relay 220 are electrically connected with the control panel 300, which eliminates the wire harness for electrically connecting the main positive relay 210 and the main negative relay 220 with the control panel 300, and makes the installation convenient and the integration high.

[0073] In one possible implementation, referring to Figure 1 and Figure 4 and in combination with Figure 5 , the support 301 and the slave board 302 are further included.

[0074] The support 301 is used to be connected with the battery pack, and the support 301 has a support cavity inside, and the slave board 302 is arranged in the support cavity, and the slave board 302 is electrically connected with the control panel 300.

[0075] The slave board 302 has a first plug-in end 303, and the battery pack has a second plug-in end 304.

[0076] The first plug-in end 303 is plugged with the second plug-in end 304, so that the slave board 302 obtains the state parameters of the battery pack and transmits the state parameters of the battery pack to the control panel 300.

[0077] In the above embodiment, the second plug-in end 304 on the battery pack is plugged with the first plug-in end 303 on the slave board, so that the slave board 302 obtains the state parameters of the battery pack and transmits the state parameters of the battery pack to the control panel 300, which eliminates the connecting wire harness between the slave board 302 and the battery pack, further simplifies the internal structure of the battery pack, and makes the maintenance convenient.

[0078] Meanwhile, the support 301 can provide a fixed installation position for the slave board 302, so that the slave board 302 is stable during work and avoids disconnection with the battery pack due to shaking and the like.

[0079] In specific implementation, the number of the support 301 and the slave board 302 can be selected according to actual needs, and the application does not limit the specific number of the support 301 and the slave board 302. Of course, the specific number of the first plug-in end 303 on each slave board 302 is also not limited, as long as the number of the second plug-in end 304 of the battery panel is consistent with that of the first plug-in end 303 and the plug-in is corresponding.

[0080] In a possible implementation, one of the first plug end 303 and the second plug end 304 is a female socket, and the other is a male plug. By setting the female socket and the male plug in a manner of being in butt joint, the first plug end 303 and the second plug end 304 are quickly plugged, and the structure is simple, the installation and dismounting process is convenient, and the maintenance is simple.

[0081] In a possible implementation, referring to Figure 6 Fig. 6, the battery energy distribution unit further comprises a shunt 260, and the shunt 260 is plugged with the control board 300. Specifically, the shunt 260 is plugged with the control board 300 through a floating connector 261.

[0082] Here, by setting the shunt 260 in a manner of being plugged with the control board 300, the connecting wire harness between the shunt 260 and the control board 300 is further omitted, in addition, the floating connector 261 can absorb and correct the direction error in the assembly process, reduce the assembly problems caused by inaccurate positioning, and improve the flexibility of design and the degree of freedom of layout. It can be understood here that in the driving process of the vehicle, it is inevitable to be affected by factors such as vibration. The shunt 260 is connected with the control board 300 through the floating connector 261, the control board 300 and the shunt 260 are plugged in a manner, which can reduce the influence of external impact and vibration, and improve the reliability of the system.

[0083] The application further provides a battery pack, comprising a battery pack body 700 and the above-mentioned battery energy distribution unit arranged in the battery pack body 700.

[0084] Wherein, the specific structure of the battery energy distribution unit has been described above, and will not be repeated here, the battery pack body 700 is the prior art in the related technical field, and it can be understood that the battery energy distribution unit provided by the application can be applied to any battery pack body 700.

[0085] By using the above-mentioned battery energy distribution unit in the battery pack, the battery pack can have fewer connecting wire harnesses, and the connection mode of the internal parts is simplified, thereby facilitating the later maintenance.
