Temperature Swing Effects on Cold-Storage Forklift Batteries

Cold storage working scenarios usually maintain a constant temperature below minus 18 degrees Celsius, and the frequent entry and exit of forklifts between normal temperature operation areas and low temperature storage areas will bring continuous temperature swing impact to the matching power batteries. Most lead-acid and lithium-ion batteries used for industrial electric forklifts have clear performance variation rules under different ambient temperature conditions. When the forklift moves from the zero-degree or above charging and waiting area into the cold storage area, the surface temperature of the battery pack drops rapidly, the viscosity of the internal electrolyte increases, the chemical reaction activity of the pole piece decreases, and the available discharge capacity will drop by a certain percentage if the operation lasts for more than 30 minutes. When the forklift returns to the normal temperature area after long time operation in cold storage, the condensed water formed by the temperature difference will attach to the surface of the battery shell, which may cause potential short circuit risk if the water accumulation is not cleaned in time. Long term unprotected temperature swing circulation will accelerate the aging of the internal battery structure, reduce the cycle life, and bring unstable power output in peak operation periods. For industrial users who need to run forklifts in cold storage scenarios all year round, it is recommended to formulate targeted battery management specifications, preheat the battery pack to the specified working temperature before entering the low temperature area, arrange the charging process at the ambient temperature above zero, and regularly check the sealing performance of the battery shell to avoid condensed water infiltration.
