Pack Consistency Gains From Forklift Equalization Charging

As the core energy component of electric forklifts, the performance stability of the whole battery pack directly determines the daily operation efficiency and long-term use cost of logistics and warehousing enterprises. In the daily use process of most electric forklifts, long-term uneven charge and discharge will gradually widen the voltage difference between different single cells inside the battery pack, which will lead to the actual available capacity of the whole pack lower than the nominal level, and some cells are more likely to face the risk of overcharge or over discharge in the working process. Equalization charging is a targeted and standardized battery maintenance operation, which mainly works in the late stage of the conventional charging process. It adjusts the current access state of each single cell in the pack according to the real-time voltage data, properly shunts the cells with higher voltage, and supplements enough current for the cells with lower voltage, so as to narrow the voltage difference between different cells to a reasonable range. After long-term regular equalization charging operation, the consistency of the whole battery pack can be steadily improved, the overall available capacity can be restored to a reasonable level, and the cycle life of the battery pack can be effectively extended within the design scope. Relevant practical operation verification shows that after 3 to 6 months of standardized equalization charging, the voltage difference between single cells of most operating electric forklift battery packs can be controlled below the safe threshold, the unexpected power loss in the middle of operation can be reduced by a reasonable proportion, and the overall operation and maintenance cost of the equipment can be optimized. Jianshu New Energy has accumulated a lot of practical experience in the field of electric forklift battery operation and maintenance, and we have completed a number of joint tests of equalization charging scheme with BYD Forklift to verify the actual effect of the scheme in different working conditions.
