How Forklift Battery Range Drops in Freezer Warehouses

Freezer warehouses usually maintain a constant low temperature ranging from -18℃ to even below -30℃ for long-term storage of frozen food, medical supplies and special industrial materials, which creates huge challenges for the normal operation of electric forklifts that work inside for a long time. The core reason for the range drop of electric forklift batteries in such scenarios comes from the change of internal electrochemical characteristics under low temperature environment. Low ambient temperature will reduce the activity of the internal electrochemical substances of the power battery, increase the internal resistance significantly, and the available discharge capacity of the battery will decrease correspondingly, which directly leads to the obvious drop of the continuous working range of the forklift. Many logistics operators find that a fully charged electric forklift that can work for 8 hours at normal temperature can only support 4 to 5 hours of continuous operation in the freezer warehouse without proper pre-heating measures. There are also other auxiliary factors that further enlarge the range drop. The frequent door opening and closing of the freezer warehouse leads to alternating temperature changes, the slight condensation on the surface of the battery components will also increase the extra power consumption of the protection system, further accelerating the loss of effective range.

You do not need to replace the whole set of power system blindly, through regular battery performance testing and targeted low-temperature transformation, most electric forklifts can maintain more than 80% of the normal temperature working range under the low temperature environment above -25℃. It is also recommended that the operation team arrange the driving route reasonably, reduce the unnecessary long distance travel inside the low temperature area, arrange proper intermittent rest for the forklift to stay in the normal temperature buffer zone for a short period, and avoid over-discharging the battery in the low temperature state, which can effectively prolong the service life of the forklift battery and reduce the overall operation cost of the cold storage.
