Equalization Charging Routine for Forklift Batteries

Equalization charging is a core part of regular maintenance for most lead-acid forklift batteries, which can effectively solve the problem of inconsistent voltage and capacity among single battery cells caused by long-term repeated charge and discharge cycles, and avoid premature capacity decay of the whole battery pack. Before starting the equalization charging process, you need to confirm the remaining power of the battery pack is between 20% and 30% after normal discharge, do not carry out this operation when the battery is fully charged or severely undercharged. You also need to check the battery shell for no crack or leakage, the connection terminals are free of oxidation and looseness, and the charging site is well ventilated with no flammable and explosive materials around, and the ambient temperature is kept between 0 and 40 degrees Celsius. After starting the equalization charging, monitor the total voltage and current of the battery pack in real time, do not set the charging voltage beyond the maximum value specified by the battery manufacturer. Once the battery surface temperature exceeds 45 degrees Celsius during operation, pause the process immediately and resume it until the temperature drops to the normal range. After the whole equalization charging process is finished, let the battery stand for 1 to 2 hours, then test the voltage difference of each single cell to confirm the value is within the reasonable range before putting the battery into use. Standardized periodic equalization charging can effectively extend the overall service life of forklift batteries and reduce unnecessary equipment operation cost. For frequent used electric forklifts in warehouse scenarios, proper equalization charging routine can also lower the probability of unplanned shutdown and improve work efficiency.

Jianshu New Energy has rich practical experience in electric industrial power system maintenance, the above operation specifications are also suitable for the supporting battery maintenance scenarios of BYD Forklift full product lines. All operators need to receive professional safety training before conducting equalization charging, follow relevant industrial safety regulations strictly, and do not overdo equalization charging too frequently, usually once every 10 complete charge-discharge cycles is enough, excessive operation will cause extra damage to the battery plates.
