Application of J1939 Cable in Commercial Vehicle New Energy System

With the increasing awareness of environmental protection and the adjustment of energy structure, new energy commercial vehicles have gradually become the mainstream of the market. J1939 cables also play an important role in new energy commercial vehicles, providing reliable communication support for the stable operation and efficient management of new energy systems.

In new energy commercial vehicles, the Battery Management System (BMS) is one of the core components. J1939 cable can connect the battery management system with other ECUs of the vehicle, achieving real-time monitoring and management of battery status. Through J1939 cable, BMS can transmit real-time parameters such as battery voltage, current, temperature, etc. to other ECUs, ensuring that the battery operates within a safe and efficient range. Meanwhile, other ECUs can also adjust the vehicle's driving strategy and improve energy efficiency based on the battery status information.

The motor control system is also an important component of new energy commercial vehicles. J1939 cable can connect the motor controller with other systems of the vehicle, achieving precise control and coordinated operation of the motor.

In addition, J1939 cables also support communication between the charging system of new energy commercial vehicles and the vehicles. During the charging process, the charging device can communicate with the vehicle's BMS through J1939 cable to understand the charging status and requirements of the battery, achieving intelligent charging and safety protection.
