Spotting Battery Degradation Signals From Usage Data

Electric forklifts are widely used in modern warehousing, manufacturing and logistics scenarios, and the power battery is the core component that directly determines its continuous operation efficiency. Most operators used to judge battery health only by subjective experience or occasional manual testing, which often misses the early warning period of degradation and leads to unexpected downtime that disrupts normal production arrangements. By sorting out and analyzing daily usage data of the equipment, frontline managers can accurately spot potential battery degradation signals in advance without extra complicated testing processes. The first key signal to track is the consistency of full-charge working duration. If the full load continuous working time of the forklift drops by more than 10% within a short period of time without any change in daily operation intensity, working temperature and load weight, it usually indicates that the battery active material has begun to appear irreversible loss to a certain extent. The second signal to monitor is the change of charging efficiency data. If the total charging time required to reach 100% state of charge increases obviously compared with the normal level in early usage, or the actual available power obtained per unit charging input decreases gradually, it is another typical early sign of battery performance recession. The third noticeable signal comes from the discharge voltage curve during daily operation. If the voltage drops much faster than the normal reference level under the same load condition, the actual capacity of the battery has already deviated from the original rated parameter range. For operation teams that manage a large fleet of electric forklifts, establishing a regular data sorting and checking mechanism can effectively extend the overall service life of power batteries and reduce unnecessary equipment replacement cost. Jianshu New Energy has accumulated rich practical experience in battery health analysis for new energy industrial handling equipment, and related technical teams can also provide targeted professional guidance for users of BYD Forklift to build a complete battery full-cycle management system.
