2results about How to "Simplify the wiring harness" patented technology

This invention discloses a plug-in board and adapter, associated electrical components, and an electric vehicle. The plug-in board includes an MCU circuit I, an adapter communication circuit, and a controller circuit. Some models also include a BMS battery management circuit, a vehicle electrical and electronic fuse circuit, a taillight control circuit, a communication line starting power supply circuit, a human-machine interaction circuit, and a battery communication circuit. The plug-in board is soldered to the controller's PCB circuit board via pins, or connected to the pins on the controller's PCB board via a socket. The plug-in board and the controller are housed in a single housing, saving space, material costs, and labor costs. The original controller's MCU chip can be improved to enhance controller performance and enable the application of bus control systems without modification, greatly simplifying the wiring harness and connectors throughout the vehicle.

The application discloses a vehicle integrated lithium battery high-voltage power distribution system and a control method. The lithium battery high-voltage power distribution system comprises a high-voltage distribution box, a plurality of battery boxes and a connecting cable for connecting the high-voltage distribution box and the battery boxes and two groups of the battery boxes, which are stacked from top to bottom. The high-voltage distribution box is integrated with a control panel, a filter, a DCDC, a contactor, a fuse, a hard copper bar and a current sensor. The battery box is integrated with a BMS control box. The battery boxes are also connected with liquid cooling pipelines. The system effectively reduces the space occupied by the high-voltage power distribution system on the chassis by using the integrated design of the lithium battery high-voltage power supply and distribution system. By integrating multiple functional modules in one whole, the device layout and installation space are saved, the complexity of the system and the high-voltage cable wiring are reduced, the generalization and interchangeability of the lithium battery and the high-voltage power distribution system are improved, and the redundancy of the vehicle power supply and distribution system is ensured.
