CAN Bus Battery Charger

CAN Bus Battery Charger (battery charger with CAN bus communication function) is an intelligent battery charger that communicates with other systems or devices through the CAN bus protocol (Controller Area Network). It is often used in occasions that require centralized control, status monitoring and high reliability, such as electric vehicles, electric forklifts, energy storage systems, industrial equipment, etc.

Working principle:

The basic working principle of CAN Bus Battery Charger combines traditional charging technology with digital communication technology:

Battery charging control: Use different charging curves (such as constant current-constant voltage-trickle current, etc.) to charge the battery according to the battery type (such as lead-acid, lithium-ion, etc.).

CAN communication module: The charger has a built-in CAN controller, which communicates with BMS (battery management system), main controller, vehicle network, etc. through the CAN bus.

Real-time monitoring and adjustment:

Receive battery voltage, current, temperature, SoC (state of charge) and other data sent by BMS;

Dynamically adjust charging parameters according to battery status to achieve intelligent charging;

Can send alarms, completion signals and other information back to the main controller.

Safety protection functions: such as overvoltage, overcurrent, overtemperature, short circuit protection, etc., and support remote shutdown of the charger through CAN.

Main features:

Support CAN 2.0A/B or higher protocols (such as CANopen, J1939, etc.)

Intelligently adjust the charging curve to adapt to different battery chemical systems

Real-time communication and remote control functions

Modular design, easy system integration

Built-in multiple safety protection mechanisms

Scope of application:

Electric vehicles (EV, AGV, forklift, sightseeing car)

CAN Bus Battery Charger is responsible for real-time communication with BMS in electric vehicles such as EV, AGV, forklift and sightseeing car, intelligently adjust the charging process to ensure safety and efficiency. Support remote control and fault diagnosis, improve charging efficiency and extend battery life. Its high integration facilitates vehicle management and is suitable for fleet scheduling and intelligent charging systems.

Industrial automation equipment (robots, automatic handling systems)

CAN Bus Battery Charger is used in industrial automation equipment to charge the batteries of mobile devices such as AGVs and robots. It communicates with BMS and control systems through the CAN bus to achieve intelligent charging, status monitoring and remote control, improve charging safety and efficiency, and adapt to the needs of smart factories and unmanned operations.

Energy storage system (home/commercial energy storage, solar energy storage system)

CAN Bus Battery Charger is used in energy storage system for intelligent charging management of battery packs. It communicates with BMS and EMS (energy management system) through CAN bus to achieve real-time monitoring of charging status, parameter adjustment and fault warning, ensuring efficient and safe operation of the system, and is widely used in household, commercial and photovoltaic energy storage scenarios.

UPS system (uninterruptible power supply)

CAN Bus Battery Charger is used in UPS system for efficient and stable intelligent charging of backup batteries. It communicates with BMS or monitoring system through CAN bus to adjust charging parameters, monitor battery status and provide fault alarm in real time, improve system reliability and battery life, and ensure continuous power supply to key equipment during power outages.
