When users select and use lithium-ion forklifts, the ambient temperature parameter ranges listed on official datasheets are often easily overlooked, but these values are closely related to the operational stability, service life and safety performance of the whole equipment. Most formal official datasheets divide the ambient temperature parameters into three independent and clearly marked ranges after a large number of actual working condition tests, rather than giving a single vague value.

The first core range is the normal continuous operation temperature range, which is calibrated for most conventional indoor warehouses and mild outdoor operation scenarios. Within this range, the lithium battery pack, traction motor, hydraulic system and electronic control components can all work at the rated design state, the full-load operation efficiency will not be reduced, and the power output will not be restricted by the built-in temperature control protection system. Datasheets usually note that this range applies to regular all-day shift operation without additional special operating restrictions.

The second specified range is the short-time allowable operation temperature range, which is set for temporary extreme operating scenarios such as high-temperature summer outdoor yards or low-temperature winter open areas. When the ambient temperature falls into this interval, the vehicle will start the active temperature control system to adjust the working state of core components, and a small range of power limit may be triggered in some cases, which belongs to the preset safe operation state and will not cause permanent damage to the equipment. Official datasheets usually explicitly remind that the continuous working time under this temperature range should not exceed the specified limit, and long-term full-load operation outside the normal operation range is not recommended.

The third marked range is the ambient temperature range for equipment storage. This parameter is formulated to avoid irreversible capacity attenuation of lithium battery cells, slow aging of sealing elements and abnormal performance of electronic components when the forklift is idle for a long time. It is required that the storage environment should not exceed this range even if the vehicle is not put into operation, so as to keep the equipment in good state for a long time.

In addition to the three core ranges, formal datasheets will also add relevant precondition descriptions corresponding to each temperature parameter, to clarify that the calibrated values are obtained under the standard state of normal operation of the matching temperature control components and good ventilation environment. Users can judge whether the equipment matches the actual scenario demand according to these clear parameters, and arrange daily operation and maintenance work in compliance with the specifications, so as to give full play to the use value of the lithium-ion forklift.
