46 pin 6098-7543 Auto Wiring Harness Plug Cable Electric Plug Connector

The battery module uses a formed busbar strip made of multi-layer copper skin, which is reliably connected by bolts. The busbar belt is very soft to avoid cracks at the root of the busbar and bolt connection caused by vehicle vibration. The outside of the busbar is made of insulating material for withstand voltage insulation. Usually in the series high-voltage circuit, set maintenance switch, positive and negative bus relay, pre-charging relay, pre-charging resistor and fuse, as shown. The maintenance switch is set in the middle of the series circuit, and there is a fuse inside the maintenance switch. If the loop current is too large, the fuse is disconnected, and when the maintenance switch is pulled out, the high-voltage loop is in an open state. The positive and negative busbars are respectively connected with relays to the output terminals of the external load. Only when the positive and negative busbar relays are connected can the external power supply or battery charging be performed. The high-voltage bus is also equipped with current detection devices. Currently, there are non-inductive shunts connected in series on the bus and Hall sensors installed outside the bus. Both sensors send the detected bus current to the main control box, which is used to control the bus output to prevent overcurrent, and the current should not be too large during charging and energy recovery.
