Introduction to cold and moisture-proof structure of lithium battery forklift in -18 ℃ frozen warehouse

In a refrigerated warehouse environment at -18 ° C, the dual effects of low temperature and high humidity can pose challenges to the performance and lifespan of lithium-ion forklifts, so targeted cold and moisture-proof structural design is particularly critical.

Cold and moisture proof design of battery system

The low temperature in the frozen warehouse will reduce the activity of the lithium battery, and the high humidity environment will easily cause the short circuit of the battery. Therefore, the battery system of the lithium battery forklift adopts a multi-layer protective structure. The outside of the battery module is wrapped with high-density insulation and thermal insulation material to reduce the heat loss of the battery at low temperature and maintain the working temperature of the battery within a reasonable range. The battery shell adopts an integrated sealing process, and the corrosion-resistant sealing strip blocks the intrusion path of external water vapor. At the same time, a ventilation valve is reserved to balance the internal and external air pressure to avoid internal condensation caused by temperature difference.

Electronic control system sealing protection

The electronic control system is the core Control Unit of the forklift, and the low temperature and high humidity environment can easily cause circuit failures. The electric control box adopts a fully enclosed structure, and a sealing rubber ring with waterproof and dustproof grade meeting the requirements of the low temperature environment is installed at the joints of the box to prevent water vapor from infiltrating. The internal electronic components are selected with low temperature adaptable products to ensure stable transmission of signals in the -18 ° C environment. Some key components are also equipped with small thermal insulation devices to further improve low temperature adaptability.

Body and walking system Cold and moisture proof

The sheet metal joints of the forklift body are treated with spot welding and sealant to reduce the water vapor intrusion caused by the gap. A thermal insulation protective cover is installed on the outside of the traveling motor to reduce the impact of low temperature on the motor windings and prolong the service life of the motor. Low temperature grease is used for wheel hub bearings and transmission parts to ensure good lubrication performance in low temperature environments and avoid running cards caused by grease solidification.

These cold and moisture-proof structures cooperate with each other to effectively reduce the negative impact of the -18 ° C frozen warehouse environment on lithium-ion forklifts, ensure long-term stable operation of forklifts, and meet the needs of low-temperature storage operations.
