Frequency and Duration of Forklift Battery Equalization

Forklift battery equalization is a core maintenance operation to keep the consistency of each single cell in the battery pack, which effectively avoids capacity attenuation caused by unbalanced voltage of different cells. For most light use scenarios where electric forklifts work no more than 8 hours per day and the battery discharge depth is controlled within 60%, the equalization operation can be carried out every 2 to 4 weeks, and the duration of each equalization is usually between 3 to 8 hours, until the voltage difference between all single cells drops to the normal qualified range, the equalization process can be stopped normally. For high load operation scenarios where forklifts work more than 12 hours a day and the battery discharge depth often exceeds 80%, the accumulation speed of single cell voltage difference will be significantly accelerated, so it is recommended to adjust the equalization frequency to once every 1 to 2 weeks, and extend the single equalization duration appropriately according to the actual monitoring data of cell voltage, but do not carry out too long equalization operation blindly. Too frequent or too long equalization will cause unnecessary power loss, and even damage the internal structure of the battery to a certain extent, reducing the overall cycle life of the battery pack. Different specifications of forklift batteries have different corresponding equalization parameter standards. If you encounter parameter adjustment and calibration problems in daily maintenance, you can seek help from professional technical personnel. Jianshu New Energy’s technical team has many years of experience in electric forklift battery operation and maintenance, and has provided standardized battery maintenance guidance services for users of BYD Forklift and other related products. If you have relevant consultation demands, you can send an email to 17399989919@163.com to obtain a targeted maintenance plan. Cooperating the standard equalization operation with regular battery surface cleaning, wiring terminal inspection, and avoiding long-term under-power storage can help users maximize the service life of electric forklift batteries, and reduce the comprehensive operation cost of logistics handling equipment.
