At present, new energy vehicles often use battery swap connectors to achieve the connection between the whole vehicle and the battery pack, that is, to charge or discharge the battery pack. The defect is that the existing battery swap connector is mainly used to charge and discharge the battery pack, and the current conduction is a single one-in and one-out, and it does not have a shunt function; therefore, a high-performance high-voltage junction box is required to achieve this. The high-performance high-voltage junction box has a complex structure, which makes the material cost and production cost of the whole vehicle very high, and the cost of the whole vehicle has no advantage. At the same time, the high-voltage junction box is large, and multiple outgoing lines are concentrated together, which is not conducive to equipment arrangement and heat dissipation.
