Next, embodiments of the present specification will be described in detail.
As shown in fig. 1 to 4, the distribution box of the present application includes a box body 1, a first charger connector 2, a second charger connector 3, a low-voltage power supply connector 4, a low-voltage charging connector 5, a high-voltage power supply connector 6, a high-voltage charge and discharge connector 7, a circuit on-off device 8, a circuit processor 9 and a low-voltage connector 10, which are respectively provided in the box body 1. In order to make the above-mentioned connectors quickly pluggable and to make the installation of the distribution box clear, the above-mentioned connectors are preferably arranged at intervals on the peripheral side of the box body 1, respectively.
The first charger connector 2 and the second charger connector 3 are respectively used for being connected with a vehicle-mounted charger, so that the distribution box can convert between high-voltage direct current and low-voltage alternating current through the vehicle-mounted charger. When a current flows between the first charger connector 2 and the second charger connector 3, one of the two is used as a current input end, and the other is used as a current output end.
The low-voltage power supply connectors 4 are provided with at least one, and each low-voltage power supply connector 4 is electrically connected to the first charger connector 2, respectively. The low voltage charging connector 5 is electrically connected to each of the low voltage power supply connectors 4 and the first charger connector 2, respectively.

When low-voltage current is input into the distribution box from the low-voltage charging connector 5, the low-voltage current can be supplied to the low-voltage power utilization part through the low-voltage power supply connector 4 and is input into the vehicle-mounted charger through the first charger connector 2. After the vehicle-mounted charger converts the high-voltage current into the high-voltage current, the high-voltage current is input into the distribution box through the second charger connector 3. At this time, the high-voltage current in the distribution box is output through the high-voltage power supply connector 6 and supplies power for the high-voltage power consumption part, and is output through the high-voltage charge and discharge connector 7 to charge the battery.
Accordingly, the high-voltage current in the battery can be input to the distribution box from the high-voltage charging and discharging connector 7, and output from the high-voltage power supply connector 6, so as to supply power for the high-voltage power utilization part.

If the electric power input from the low-voltage charging connector 5 is insufficient to support the electric power required for each electric device, the battery is discharged at this time, and the electric power in the battery is input from the high-voltage charging and discharging connector 7 to the distribution box.
The high-voltage power supply connector 6 includes at least a motor power supply connector 61 and an air-conditioning power supply connector 62.

The low voltage connector 10 may be used to provide low voltage power to the circuit breakers 8 and to control the switching of each circuit breaker 8 in accordance with control instructions received from the circuit processor 9.
The distribution box includes a plurality of circuit sensors (not shown) for detecting a state of the circuit. The circuit sensors are respectively arranged in one-to-one correspondence with the first charger connector 2, the low-voltage power supply connector 4, the low-voltage charging connector 5, the high-voltage power supply connector 6 and the high-voltage charging and discharging connector 7, and the circuit sensors are preferably arranged in the connectors.

Specifically, the circuit sensor can monitor the problems of leakage, overcurrent, short-circuit, over-temperature faults and the like at the first charger connector 2, the low-voltage power supply connector 4 and the low-voltage charging connector 5, so that the circuit processor 9 can more accurately disconnect the circuit on-off device 8 at the connector through the low-voltage connector 10, and further the circuit safety is ensured and the circuit conduction at other connectors is not influenced.
Meanwhile, the circuit sensor can also monitor abnormal conditions of current or voltage at the positions of the motor power supply connector 61, the air conditioner power supply connector 62 and the high-voltage charge-discharge connector 7 so as to ensure the electricity safety of the high-voltage current part.

The fuses 82 are electrically connected to the first charger connector 2, the high-voltage power supply connector 6, and the high-voltage charge/discharge connector 7 in one-to-one correspondence. If the circuit at each connector is abnormal, the circuit processor 9 can control the fuse 82 to be opened so as to protect the circuit. The fuse 82 may be replaced with a relay 81 in order to allow the circuit processor 9 to repeatedly control the on-off of the circuits at the first charger connector 2, the high voltage power supply connector 6 and the high voltage charge and discharge connector 7.
The distribution box comprises an insulating plate 11 and a current conducting plate 12.
