BYD forklift charger control board assembly

First, the basic product information

This product is the charger control board assembly supporting the BYD lithium battery forklift. It is the core cgroup part of the intelligent charger and belongs to the conventional BYD forklift accessories. The product is developed according to the electrical specifications of the original charger, integrates charging control, signal acquisition, communication interaction and other functional circuits, and can replace the main control board of the charging machine failure. It is suitable for maintenance and replacement scenarios such as charging machine failure, charging loss, and abnormal communication.

II. Core Functions

1. Intelligent control of charging process
   

   As the control core of the charger, it can perform multi-stage charging logic such as constant current and constant voltage, and cooperate with the forklift battery BMS system to complete the whole process control such as charging handshake, power regulation, and full power cutoff, and adapt to the charging characteristics of lithium iron phosphate batteries.
   

2. Real-time acquisition of running status
   

   It can collect the input and output voltage, working current, internal temperature and other operating data of the charger in real time, and continuously monitor the running state of the charger to provide data reference for fault investigation.
   

3. Abnormal operating condition protection trigger
   

   When abnormal operating conditions such as overvoltage, overcurrent, overtemperature, or short circuit are detected, the protection mechanism can be triggered in time to stop the charging output, which helps to reduce the risk of damage to the charger and battery due to abnormal operating conditions.
   

4. Human-machine interaction signal docking
   

   It can connect to the charger display panel to transmit information such as charging status, operating parameters, fault codes, etc., so that the operator can intuitively grasp the working status of the charger.
   

III. Product technical characteristics

1. Original specification adaptation design
   

   Developed according to the electrical standards of the original charger of BYD forklift, the interface definition, pin arrangement, and installation size are consistent with the original specifications. It can be replaced and installed in situ under the normal working conditions of the corresponding charging machine model, and generally no additional line changes are required.
   

2. Industrial-grade component selection
   

   The circuit board is made of industrial-grade electronic components, and its temperature resistance and anti-interference performance meet the design standards of industrial equipment. It can adapt to the conventional temperature, humidity and electromagnetic environment of the workshop, and has good operation stability.
   

3. Integrated circuit design
   

   The functions of control, acquisition, communication, and protection are integrated into a single circuit board, resulting in a high degree of integration and a compact structure, which is convenient for internal installation, maintenance, and replacement of the charger.
   

4. Factory performance test qualified
   

   The product has been tested before leaving the factory, such as on-off, function, and voltage resistance. The performance parameters meet the original design standards and can be directly debugged and used on the machine.
   

IV. Adaptation range

It is suitable for the conventional specification intelligent charger corresponding to BYD 80V lithium battery forklift, and it is suitable for CPD20, CPD25, CPD30, CPD35 and other models. It is a commonly used charger repair and replacement part in BYD accessories. It is suitable for the repair and replacement of the charger control board damaged, unable to start charging, abnormal charging parameters, BMS communication failure, protection function failure and other failure scenarios.
