BYD electric forklift battery maintenance skills: CPD40 battery life extension maintenance method

Key points of daily charging and discharging specifications

Charging environment adaptation requirements

When charging daily, it is necessary to choose a ventilated and cool exclusive area to avoid charging in direct sunlight and close to high-temperature heat sources. During the charging process, it is necessary to confirm that the charging interface is fully plugged in place to avoid abnormal heat generation caused by poor contact. After charging is completed, it is necessary to disconnect the power supply in time. Do not stay in a floating state for a long time to reduce the burden of additional battery loss.

Precautions for discharge operation

During daily operation, it is necessary to avoid deep battery emptying as much as possible. When the remaining power is less than 20%, it should be arranged to replenish energy in time. Do not operate with low power for a long time and high intensity to avoid over-discharge damage to the internal cells of the battery pack, which will affect the overall service life. During operation, it is also necessary to pay attention not to bump the surrounding structure of the battery to avoid external forces causing the internal wiring to loosen.

Routine maintenance operations

Periodic visual inspection

During each operation, you can take time to check whether the battery shell has bumped, deformed, or seeped, and simultaneously clean the dust and water stains on the battery surface to avoid the accumulation of impurities in the heat dissipation gap affecting the heat dissipation efficiency. When cleaning, you can use a dry soft rag to wipe. Do not rinse the battery body directly with water to avoid the risk of short circuit caused by liquid infiltration into the internal circuit.

Storage environment control

If the vehicle needs to be left unused for a long time, it is necessary to replenish the battery power to a range of 60 to 70% in advance, place it in a dry area with a temperature of 10 to 25 degrees Celsius, and replenish the power every other month or so to avoid irreversible capacity attenuation in the long-term storage of the battery. During the idle period, the battery shell should also be well protected to avoid heavy objects being squeezed into the battery structure.

Guidelines for handling abnormal situations

Periodic calibration of parameters

Every three months or so of use, a full charge cycle can be completed to keep the battery's internal power statistics accurate, to avoid discrepancies between the power display and the actual available capacity, and to facilitate users to more accurately judge the remaining battery life and arrange corresponding tasks.

Fault timely inspection

If the battery life is found to decline significantly during daily use, and the charging and discharging process is abnormally hot, do not disassemble the battery pack by yourself. Contact professional after-sales personnel for on-site inspection and disposal in a timely manner to avoid further expansion of the failure and ensure the safety and stability of subsequent use.
