Battery Care Tips Under High-Frequency Fast Charging

Nowadays, high-frequency fast charging solutions are widely adopted in intensive logistics, warehouse and manufacturing workshops to shorten the waiting time of electric forklift charging and improve the overall operation turnover efficiency. Many operators have noticed that improper battery care under long-term high-frequency fast charging scenarios will lead to accelerated capacity attenuation, shortened service life and even potential safety hazards, so it is necessary to form a set of standardized daily operation rules to maintain the good working condition of the batteries. Before each high-frequency fast charging operation, operators shall first check the appearance of the battery, confirm that there is no deformation, leakage or crack on the shell, and check whether the connection terminals are loose, oxidized or covered with metal debris. Do not insert the fast charging gun for power supply when the terminals are in abnormal state, so as to avoid abnormal local heating and unnecessary loss of internal structure caused by poor contact. During the fast charging process, the heat dissipation area reserved for the battery shall not be completely covered by foreign sundries, and the surrounding environment shall be kept well ventilated. It is not recommended to start fast charging immediately when the battery temperature is too high after long-time continuous heavy load operation or direct sun exposure, you can arrange the battery to stand for 15 to 20 minutes to cool down to the normal ambient temperature before formal charging. It is not recommended to exhaust the battery power to less than 10% of the remaining capacity for a long time before high-frequency fast charging. The use habit of shallow charging and shallow discharging is more in line with the chemical characteristics of batteries under frequent fast charging conditions. You can perform a full charge and then discharge to 20% remaining power every two weeks to calibrate the battery management system, so as to maintain the accuracy of power display.

In daily operation, do not mix fast charging devices that do not match the battery specification at will, to avoid unstable current output that may damage the battery performance. For batteries that need to be left idle for a long time, do not keep the full power state for storage, you can adjust the remaining power to 40% to 60%, and carry out supplementary charging every half a month to compensate for the natural power consumption, so as to avoid irreversible capacity attenuation caused by long-term power loss. Following these standardized care rules can effectively extend the cycle life of the electric forklift battery under high-frequency fast charging scenarios, reduce the overall operation and maintenance cost, and ensure the stable operation of daily work.
