In daily warehouse and logistics operation, the performance of electric forklift is closely related to the operating state of its power battery, and the battery management system acts as the core control unit to monitor and adjust the whole working status of the battery pack in real time. Many frontline operators only master basic forklift driving skills, but lack systematic understanding of the practical operation rules of the battery management system, which may lead to unnecessary battery loss and extra operation cost in long term.

In daily shift handover process, operators do not need to dismantle the battery pack for manual inspection. They can check the core data fed back by the battery management system through the on-vehicle interactive interface, including remaining state of charge, maximum temperature difference between single cells, and accumulated cycle count. If the system continuously prompts abnormal temperature difference after three consecutive startup operations, operators should report the status to the maintenance team in time, and do not carry out heavy load operation forcibly to avoid potential safety risks.

For charging operation, operators should use the matching charging device that fits the battery management system protocol. The system will automatically adjust the charging current curve according to the real-time temperature and remaining capacity of the battery pack, to avoid overcharging or overheating during the charging process. It is not recommended to leave the forklift in low power status with remaining capacity less than 10% for more than 24 hours, otherwise the low-voltage protection mechanism of the battery management system will be triggered, which will lock the output of the battery pack and affect the normal use of the vehicle later.

When the electric forklift needs to be idle for more than 7 consecutive days, operators should adjust the remaining battery capacity to the range between 40% and 60%. In this state, the battery management system will automatically start the dormancy equalization mode, reduce the unnecessary power consumption of standby components, and complete the small current balancing adjustment between single cells at the same time, to avoid capacity attenuation caused by long-term under voltage.
