[0055] As mentioned in the background technology, the battery energy distribution unit and battery management system of new energy vehicle battery packs require numerous connecting harnesses to connect various components. These harnesses occupy too much internal space, resulting in excessive size and inconvenience for integration.

[0056] To address the aforementioned technical issues, this application provides a battery energy distribution unit, a battery pack, and a vehicle. In this solution, a housing with a mounting cavity is provided, and a control board is positioned on the inner wall of the mounting cavity near the battery cell. A first relay group and a second relay group are both inserted into the control board on the side opposite to the battery cell, and are arranged adjacent to each other. A fuse is positioned below the second relay. This arrangement fully utilizes the space within the mounting cavity, reducing volume. Furthermore, the way components are inserted into the control board reduces the number of wiring harness connections, further reducing the volume of wiring harnesses and facilitating integration.

[0057] It should be noted that, Figures 1 to 7 This diagram illustrates a simplified representation of the battery energy distribution unit, battery pack, and other components in the vehicle. The specific structures of the battery energy distribution unit, battery pack, and other components in the vehicle are not limited to these examples. Figures 1 to 7 of examples.

[0058] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0059] Reference Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment provides a battery energy distribution unit for installation within a battery pack, including a housing 100, an electronic component assembly 200, and a control board 300.

[0060] The housing 100 has a mounting cavity, and the control board 300 is used to be mounted on the inner wall of the mounting cavity near the battery cell of the battery pack.

[0061] The electronic device assembly 200 includes a first relay group, a second relay group, and a fuse 240. The first relay group includes a main positive relay 210 and a main negative relay 220, and the second relay group includes a pre-charge relay 270 and a heating relay 280.

[0062] The main positive relay 210, the main negative relay 220, the fuse 240, the pre-charging relay 270 and the heating relay 280 are arranged in the mounting cavity.

[0063] The first relay group and the second relay group are arranged left and right adjacent to each other.

[0064] The main positive relay 210, the main negative relay 220, the pre-charging relay 270 and the heating relay 280 are arranged on the side of the control panel 300 away from the battery cell and are electrically connected to the control panel 300.

[0065] Here, it can be understood that the control panel 300 is arranged on the inner side wall of the mounting cavity close to the battery cell of the battery pack, and the battery pack has a rack for providing the mounting of the battery cell, and the above arrangement is equivalent to arranging the control panel 300 close to the rack, and the rack has high strength and stability and has a certain protection effect on the control panel 300.

[0066] The main positive relay 210 and the main negative relay 220 are arranged left and right adjacent to each other, and the pre-charging relay 270 and the heating relay 280 are arranged left and right adjacent to each other.

[0067] The fuse 240 is arranged below the pre-charging relay 270 and the heating relay 280.

[0068] The fuse 240, the pre-charging relay 270 and the heating relay 280 are arranged on one side of one of the main positive relay 210 and the main negative relay 220.

[0069] Part of the control panel 300 is used for the battery management system to monitor the state parameters of the battery pack, and part of the control panel 300 is used to control the opening and closing of the high-voltage electrical circuit and the low-voltage control circuit of the battery pack.

[0070] In the above embodiment, the battery management system can be integrated into the battery energy distribution unit, the functions are concentrated, and the overall installation is facilitated. The battery management system (Battery Manangement System) is also called BMS, which is an intelligent management and maintenance of each battery cell, monitors the state of the battery, prevents overcharging and overdischarging of the battery, and prolongs the service life of the battery.

[0071] 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 electrical circuit. Whether the characteristic parameters of the BDU product meet the qualified conditions has an important influence on the service life, control strategy and high-voltage electrical safety of the vehicle.

[0072] In the above embodiment, by integrating the BMS with the BDU, a BDU with BMS function, i.e. a BDMU (Battery energy Distribution Manangement Unit) is formed.

[0073] In addition, the main positive relay 210, the main negative relay 220, the pre-charge relay 270 and the heating relay 280 are all arranged on the side of the control board 300 away from the battery cell and are electrically connected with the control board 300.

[0074] In this way, the connection of a plurality of wiring harnesses is saved, the electrical connection of the main positive relay 210, the main negative relay 220, the pre-charge relay 270 and the heating relay 280 with the control board 300 is facilitated, the space of the installation cavity in the housing 100 can be saved, in addition, the main positive relay 210 and the main negative relay 220 are arranged adjacent to each other, and the pre-charge relay 270 and the heating relay 280 are arranged adjacent to each other. The fuse 240 is arranged below the pre-charge relay 270 and the heating relay 280. The fuse 240, the pre-charge relay 270 and the heating relay 280 are all arranged on one side of one of the main positive relay 210 and the main negative relay 220. The above arrangement makes the main positive relay 210, the main negative relay 220, the pre-charge relay 270 and the heating relay 280 and the fuse 240 compact in layout and easy to integrate.

[0075] In a possible embodiment, a shunt 260 is further included, which is arranged on the side of the control board 300 away from the battery cell and is electrically connected with the control board 300.

[0076] The main positive relay 210 and the main negative relay 220 are arranged between the shunt 260 and the fuse 240.

[0077] In the above embodiment, referring to Figure 2 As shown in the figure, the main positive relay 210 and the main negative relay 220 are arranged between the shunt 260 and the fuse 240, which is equivalent to that the shunt 260, the main positive relay 210, the main negative relay 220 and the fuse 240 are arranged in sequence horizontally, which is compact in structure and can reduce the volume of the control board 300 and the waste of unnecessary space.

[0078] In a possible implementation, the shunt 260 is further connected to the control board 300 through a floating connector 261. Here, by arranging the shunt 260 to be connected to the control board 300 in the form of plugging, the connection harness between the shunt 260 and the control board 300 is further omitted. In addition, the floating connector 261 can absorb and correct the orientation error during assembly, reduce the assembly problems caused by inaccurate positioning, and improve the flexibility of design and the freedom of layout. It can be understood here that the vehicle will inevitably be affected by factors such as vibration during driving, and the shunt 260 is connected to the control board 300 through the floating connector 261. The control board 300 and the shunt 260 are connected in the form of plugging, which can reduce the influence of external impact and vibration and improve the reliability of the system.

[0079] In another possible implementation, as shown in Figure 2 、 Figure 3 Figure 4 and Figure 5 , the pre-charging relay 270 and the heating relay 280 are arranged above and below the main positive relay 210 and the main negative relay 220. One of the main positive relay 210 and the main negative relay 220 is arranged horizontally adjacent to the fuse 240, and one of the main positive relay 210 and the main negative relay 220 is arranged between the fuse 240 and the pre-charging relay 270 and the heating relay 280.

[0080] In the above embodiment, the pre-charging relay 270 and the heating relay 280 are arranged between the main positive relay 210 and the main negative relay 220. It can be understood that the main positive relay 210 and the main negative relay 220 generate a large amount of heat during operation. By separating the main positive relay 210 and the main negative relay 220 with the pre-charging relay 270 and the heating relay 280, the superposition of heat can be reduced, and the overheating phenomenon caused by the superposition of heat can be avoided. In addition, the pre-charging relay 270 and the heating relay 280 have smaller volume and weight relative to the main positive relay 210 and the main negative relay 220. By arranging the pre-charging relay 270 and the heating relay 280 between the main positive relay 210 and the main negative relay 220, the weight distribution on the control board 300 can be balanced, the installation stress of the control board 300 is uniform, and the stability is improved.

[0081] In a possible implementation, as shown in Figure 1 and Figure 6 , the support 301 and the from plate 302 are further included.

[0082] The support 301 is used to be connected to the battery pack. The support 301 has a support cavity therein, and the from plate 302 is arranged in the support cavity. The from plate 302 is electrically connected to the control board 300.

[0083] The slave board 302 has a first plug end 303, and the battery pack has a second plug end 304.

[0084] The first plug end 303 is used for plugging with the second plug end 304, so that the slave board 302 acquires the state parameters of the battery pack and transmits the state parameters of the battery pack to the control board 300.

[0085] In the above embodiment, 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 the slave board 302 is prevented from being disconnected from the battery pack due to shaking and the like.

[0086] The second plug end 304 on the battery pack is plugged with the first plug end 303 on the slave board 302, so that the slave board 302 acquires the state parameters of the battery pack and transmits the state parameters of the battery pack to the control board 300, the connection harness between the slave board 302 and the battery pack is eliminated, the internal structure of the battery pack is further simplified, maintenance is convenient, and the volume is further reduced.

[0087] 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 end 303 on each slave board 302 is also not limited, as long as the number of the second plug end 304 of the battery board and the first plug end 303 is consistent, and the corresponding plug is implemented.

[0088] 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 abutting, the first plug end 303 and the second plug end 304 are quickly plugged, which has the effects of simple structure, convenient installation and dismounting process, and convenient maintenance.

[0089] 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.

[0090] The first shell 110 is used for connecting with the cold plate 500 of the battery pack, and the second shell 120 is arranged on the first shell 110, and the first shell 110 and the second shell 120 jointly enclose an installation cavity.

[0091] 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.

[0092] The first clamping piece 111 and the second clamping piece 121 are correspondingly clamped.

[0093] 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 realized, 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.

[0094] 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 work. In order to timely dissipate heat from the battery cells, a 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 maintain the optimal temperature. The specific structure of the cold plate 500 is not limited in the embodiments of the present application.

[0095] The first shell 110 is connected with the cold plate 500. In this way, the cold plate 500 on the battery pack is used to dissipate heat from the shell 100, improving the heat dissipation efficiency, which is equivalent to dissipating heat from the battery energy distribution unit and the battery management system at the same time, and indirectly dissipating heat from the electronic component 200 and the control board 300.

[0096] In a possible implementation, the control board 300 has at least one connection port 900. The connection port 900 can be a connection port 900 for communication connection between the control board 300 and the vehicle. The connection port 900 needs to be plugged with a wire harness to realize the communication connection with the vehicle.

[0097] Referring to Figure 7 As shown in the figure, the second shell 120 has a relief groove 122, and the connection port 900 penetrates the second shell 120 and extends into the relief groove 122.

[0098] In the above embodiment, the connection port 900 is conveniently and electrically connected with the vehicle by setting the relief groove 122.

[0099] The present application also provides a battery pack, which comprises a battery pack body 700 and the above-mentioned battery energy distribution unit arranged in the battery pack body 700.

[0100] 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 prior art in the related technical field, and it can be understood that the battery energy distribution unit provided by the present application can be applied to any battery pack body 700.

[0101] By using the above battery energy distribution unit in the battery pack, the number of connection harnesses in the battery pack can be reduced, the connection mode of internal components is simplified, and thus the later maintenance is facilitated.

[0102] The application also provides a vehicle, comprising a vehicle body and the above battery pack arranged on the vehicle body.

The fuse 240, the pre-charging relay 270 and the heating relay 280 are all arranged on one side of one of the main positive relay 210 and the main negative relay 220. By the above arrangement mode, the space in the mounting cavity can be fully utilized, the volume occupation is reduced, and the arrangement mode of the components inserted on the control board 300 can reduce the connection of many harnesses, further reduce the volume occupation of the harnesses, and facilitate integration.
