Cold-Air Charging Effects on Lithium Forklift Battery Life

Many enterprises that operate electric forklifts in cold storage, northern outdoor logistics yards or low-temperature processing workshops often overlook a hidden factor affecting battery performance: continuous cold air blowing directly on the battery pack during the charging process. Most standard lithium forklift batteries are designed to complete charging operations within the ambient temperature range of 0 to 45 degrees Celsius, and if the battery core temperature is dragged below 0 degrees by continuous cold air flow while the charging current is input, the internal electrochemical reaction of the battery will deviate from the optimal path. Long-term exposure to this cold-air charging condition will accelerate the attenuation of battery active materials, reduce the total number of effective charge-discharge cycles, and lead to the gradual reduction of available battery capacity, which will ultimately make the overall service life of the lithium battery lower than the expected standard value. Industry statistics show that continuous improper cold air charging without intervention may reduce the actual service life of lithium forklift batteries by nearly 30% in a 2-year use cycle, bringing additional unplanned equipment replacement costs to logistics and manufacturing enterprises. To avoid such unnecessary loss, operation and maintenance personnel should first check the ambient temperature of the charging position before starting charging, block the cold air outlet facing the charging area, and stop charging immediately if the surface temperature of the battery pack is too low, and start the charging process only after the battery core returns to the suitable temperature range.
