Key points for maintenance of lithium batteries in summer

1. Avoid high temperature environment
Avoid storage and use in high temperature environment
The current mainstream lithium battery is lithium iron phosphate (LiFePO4) power battery, which is sensitive to temperature changes. Long-term operation under high temperature conditions has potential adverse effects on the reliability and life of lithium batteries.
The optimal operating temperature of lithium batteries is 15℃~35℃. Working at a suitable temperature can keep lithium batteries at their best energy efficiency and charging capacity. Charging in high temperature or closed spaces should be avoided, and the temperature of the working environment of lithium forklifts should be reduced as much as possible, such as ensuring ventilation and taking good sunshade measures.

2. Develop correct charging habits
Reasonably arrange the frequency of charging and discharging
Lithium batteries will generate heat during charging, discharging and use. When the battery is continuously charged and discharged at high load, and the high temperature environment in summer accumulates, the battery temperature will gradually increase, and the battery will overheat. The use of the vehicle should be arranged reasonably, and the lithium battery should be given enough time to stop and cool down to avoid the superposition of charging and discharging heat to damage the battery.

Avoid excessive discharge
In a high temperature environment, the self-discharge rate of the battery will increase, which will lead to a decrease in battery capacity. To avoid over-discharge, it is recommended to charge the battery in time when the battery power drops to 20%.

Separate the charging areas of lead-acid and lithium batteries
The charging areas of lead-acid batteries and lithium batteries should be separated as much as possible to avoid the volatilization of sulfuric acid gas from lead-acid batteries at high temperatures and during charging, which may corrode the modules and circuit boards of lithium battery chargers and easily damage the lithium battery chargers.

Keep the battery and charger clean
Do not charge in high temperature, high dust, or salt spray environments. When charging, keep the surface of the charging interface clean, and there should be no particles, dust, or other debris in the interface. Clean the dust from the charger vents regularly to improve ventilation and heat dissipation capabilities
Strongly recommended
In addition to daily maintenance of lithium batteries, daily monitoring and management should also be strengthened. It is recommended to use KION Forklift Energy Management Platform EMS, which can realize "energy digitalization" management of the entire life cycle of lithium batteries through remote real-time monitoring of batteries, output battery working energy efficiency analysis, battery fault alarms, temperature monitoring, battery health checks, etc.
