Charging Precautions for Lithium Packs in Freezer Rooms

Many logistics and food processing facilities run freezer rooms with sub-zero temperatures to store temperature-sensitive goods, and electric forklifts equipped with lithium packs are widely used for daily material handling in such scenarios. Improper charging of lithium packs in low temperature freezer rooms will not only reduce battery cycle life, but also bring potential safety risks if operations are not carried out in a standardized way. First of all, operators need to move the lithium pack or the whole forklift out of the freezer room to a designated normal temperature charging area before charging, instead of performing charging operations directly in the low temperature environment inside the freezer. The electrolyte activity of lithium batteries will drop sharply at temperatures below zero, direct charging will lead to lithium precipitation on the electrode plate, which will cause irreversible damage to the internal structure of the battery. Secondly, before connecting the charging plug, operators need to check the surface temperature of the lithium pack to confirm that it has risen to between 0 and 40 degrees Celsius, which is the standard operating temperature range for normal charging. If the battery is still covered with condensed frost that has not melted completely, do not plug in the power supply for charging, you should wipe the water and frost on the shell, interface and cable of the battery completely with a dry non-conductive cloth to avoid short circuit risk caused by water immersion. Thirdly, during the whole charging process, special personnel should be arranged on duty to monitor the changes of battery temperature, current and voltage in real time, and do not overcharge the lithium pack beyond the specified charging time. When the battery is fully charged, cut off the power supply in time and pull out the charging plug. After the battery is fully charged, it is recommended to let the battery stand for 30 to 60 minutes to return to normal working temperature before it can be driven back to the freezer room for operation. For users who use BYD Forklift equipment for daily cold storage handling, the above operation specifications can effectively maintain the stable performance of the supporting lithium power system.

In addition, operators should regularly carry out safety inspection on the charging equipment, cable and interface of lithium packs, and replace the aging wires and damaged accessories in time, so as to eliminate hidden dangers from the source. Strict implementation of these standardized charging precautions can not only effectively extend the service life of lithium packs, reduce equipment operation and maintenance costs, but also ensure the safety and stability of electric forklift operation in the freezer room, and avoid unnecessary production downtime caused by battery failure.
