The number of the shunt box 1100 is seven, and each shunt box 1100 is stacked, each shunt box 1100 is connected with two battery clusters, and at least two direct currents are output. The at least two direct currents comprise a first direct current and a second direct current. The number of the current converter 1200 is equal to the number of the shunt box 1100, each current converter 1200 is arranged on one side of each shunt box 1100, each current converter 1200 is electrically connected with a corresponding shunt box 1100, and each current converter 1200 is used for converting each first direct current into an alternating current. The second direct current is input into a first power supply end. Compared with a traditional shunt device 1000 which can only output one current, each shunt box 1100 in the present application can output two currents, the shunt efficiency is improved, in addition, each current converter 1200 is electrically connected with a corresponding shunt box 1100, and each current converter 1200 can convert each first direct current into an alternating current, that is, the shunt device 1000 in the present application can simultaneously output alternating current and direct current, and the application range of the power supply end is increased.

[0044] Please refer to Figure 1 and Figure 3 In some embodiments, the shunt device 1000 further comprises a support 1600. The support 1600 is arranged along a preset direction. The preset direction is an X direction in Figure 4 Each shunt box 1100 is stacked on the support 1600 along the preset direction, and each shunt box 1100 is at least partially exposed from the support 1600. Each current converter 1200 is stacked on the support 1600 along the preset direction, each current converter 1200 is arranged opposite to each shunt box 1100, and each current converter 1200 is at least partially exposed from the support 1600.

[0045] It can be understood that the support 1600 is a multi-layer shelf, and the support 1600 is made of hard material to provide a stable support structure. The shunt box 1100 and the current converter 1200 are arranged on the support 1600, which reduces the space occupied by the shunt device 1000 and improves the space utilization.

[0046] In some embodiments, the converter 1200 is an energy storage converter, and each converter 1200 includes a connection terminal. Each connection terminal is exposed from the support member 1600 to provide a connection channel for quick assembly and disassembly of the connection terminal from other components.

[0047] Please see Figure 1 and Figure 2 In some embodiments, each of the distribution boxes 1100 includes: a box body 1110, an input connector 1120, and an output connector 1130. The box body 1110 is prismatic and includes: a containment portion and a support portion. The support portion extends along... Figure 4 The Y-direction is set in the middle, and the Y-direction is perpendicular to the X-direction. The supporting part is a square plate. The enclosure part is arranged around the periphery of the supporting part and is connected to the supporting part to form a receiving space 1111. There is one input connector 1120, and the input connector 1120 is located on the side of the enclosure part away from the receiving space 1111. One input connector 1120 is connected to two battery clusters. The number of output connectors 1130 is equal to the number of input connectors 1120. The output connectors 1130 are located on one side of the input connectors 1120. One output connector 1130 outputs one first DC power and one second DC power.

[0048] In other embodiments, the number of input connectors 1120 can be adjusted to two, three, four, five, etc., according to actual needs, which will not be listed here.

[0049] Please see Figure 2 In some embodiments, one of the output connectors 1130 includes a positive connector 1121 and a negative connector 1122. There are two positive connectors 1121 and two negative connectors 1122. The two battery clusters are electrically connected to the two positive connectors 1121 and the two negative connectors 1122, respectively.

[0050] Please see Figure 2In some embodiments, each of the shunt boxes 1100 further comprises a first copper bar 1140, a second copper bar 1150 and a first circuit breaker 1160. The first copper bar 1140, the second copper bar 1150 and the first circuit breaker 1160 are all arranged in the accommodating space 1111. The first copper bar 1140 is arranged on the bearing part, and the first copper bar 1140 is electrically connected with the output connector 1130. The first circuit breaker 1160 is arranged on the bearing part. The second copper bar 1150 is arranged on the bearing part, the second copper bar 1150 is electrically connected with the first copper bar 1140, and the second copper bar 1150 is connected with the first circuit breaker 1160.

[0051] In some embodiments, a charging pile is arranged on the first power supply end. The output connector 1130 is electrically connected with the first power supply end. When the first power supply end is in a power supply state, that is, the charging pile is in an operating state, one way of the second direct current is output from the first circuit breaker 1160 to the output connector 1130 and then output from the output connector 1130 to the first power supply end.

[0052] It can be understood that the second direct current output by the first power supply end is output in the charging pile. In a conventional charging pile, direct current is converted into alternating current so that the charging pile can provide alternating current. However, in the process of converting direct current into alternating current, the energy loss is large. Compared with an alternating current charging pile, the direct current charging pile in the present application can reduce the energy loss caused by the conversion of direct current into alternating current, thereby reducing the power consumption cost.

[0053] In some embodiments, the output connector 1130 is electrically connected with one of the current conversion members 1200. One way of the first direct current is output from the second copper bar 1150 to the output connector 1130 and then output from the output connector 1130 to one of the current conversion members 1200, so as to convert one way of the first direct current into one way of alternating current.

[0054] It can be understood that two battery clusters are electrically connected with one shunt box 1100, and two ways of current can be output by one current box. Compared with a conventional shunt device 1000 which can only output one way of current, the shunt device 1000 in the present application can simultaneously output two ways of current, has high shunt efficiency, and can simultaneously output direct current and alternating current, thereby having a wide range of applications.

The first circuit breaker 1160 is electrically connected to the positive copper bar 1141 and the negative copper bar 1142.

[0057] It can be understood that the first copper bar 1140 is used to converge the direct current and output the converged direct current in two ways, one way is output through the second copper bar 1150, that is, the first direct current, and the other way is output through the first circuit breaker 1160, that is, the second direct current.

[0058] In some embodiments, the first circuit breaker 1160 is a direct current circuit breaker, and the first circuit breaker 1160 can control the on-off of the second direct current between the first circuit breaker 1160 and the first power supply end, so as to play a circuit protection role on the first power supply end.

[0061] In some embodiments, the second circuit breaker 1500 is an alternating current circuit breaker. One of the alternating currents output by the corresponding current conversion member 1200 is input into the corresponding second circuit breaker 1500 and is output from the corresponding second circuit breaker 1500 to the bus bar 1300. The second circuit breaker 1500 is used to protect the alternating current, and each of the second circuit breakers 1500 is used to control the on-off of the alternating current between the corresponding current conversion member 1200 and the bus bar 1300.
