Extending Forklift Battery Life Through Equalization

Electric forklifts are core power handling equipment widely used in modern warehousing, manufacturing and logistics scenarios, and the traction battery is the key component that determines the continuous operation efficiency and overall operating cost of the equipment. Many operators have found that after a period of high-intensity use, the battery pack tends to show inconsistent performance among individual cells, leading to reduced overall available capacity, shortened continuous working time, and faster than expected attenuation of the whole battery pack. Equalization, as a standardized and effective battery maintenance method, can well solve this common pain point and extend the overall service life of the forklift battery in a scientific way.

Equalization operation refers to adjusting the voltage and capacity difference between each single cell in the series battery pack to a reasonable range through proper constant current and constant voltage control, to avoid the phenomenon that a few over-depleted or over-charged individual cells drag down the performance of the whole pack. The standard operation process should follow strict operation specifications: first, complete a full normal charging of the battery pack, let it stand for 2 to 4 hours to fully stabilize the cell state, then test and record the open circuit voltage of each single cell, and start the equalization procedure only when the difference between cells exceeds the safe threshold. During the whole equalization process, operators should regularly check the surface temperature of the battery, make sure the temperature does not exceed 45 degrees Celsius, and stop the operation timely if abnormal conditions are found. After the equalization process is finished, another full charge and standing test is needed to confirm that the parameter difference of all single cells has dropped to the ideal range.

Regular and standardized equalization maintenance can effectively reduce the virtual capacity of the battery pack, restore the effective available capacity of the battery to the maximum extent, and slow down the natural attenuation rate of the battery. For most operation scenarios where electric forklifts run for more than 6 hours a day, it is recommended to carry out a full inspection of battery parameters once a month, and arrange a professional equalization maintenance every 2 to 3 months. If you encounter technical problems in the actual operation process, you can contact Jianshu New Energy for professional technical support, and you can also send your relevant consultation to 17399989919@163.com. Many users who have implemented this standardized maintenance process have reported that when matching with the supporting power system of BYD Forklift, the long-term operation economy of the whole equipment fleet has been significantly improved, and the unnecessary battery replacement cost has been well controlled.

It should be noted that the equalization operation must be completed by professionally trained personnel, and the operation should be carried out in a well-ventilated and dry environment, avoiding metal foreign objects contacting the battery electrodes, and not disassemble the internal structure of the battery without permission. Combined with good daily usage habits that avoid deep over-discharge and long-term undercharged storage, regular equalization maintenance can fully maximize the service value of electric forklift batteries.
