Preventative maintenance for lithium-ion batteries to prevent thermal runaway involves a combination of regular inspections and appropriate storage and handling practices. Here are some guidelines:
Maintenance Schedule
- Monthly: Perform visual inspections to identify any signs of physical damage, corrosion, or electrolyte leakage. Ensure terminal connections are clean and tight.
- Every Six Months: Charge the battery to approximately 50% of capacity at least once every six months to prevent deep discharge and degradation.
- Yearly or As Needed: Based on usage, consider replacing the battery if its run time drops below 80% of the original or if charging time increases significantly.
Essential Practices
- Cleaning: Regularly clean the battery, terminals, and connections to prevent corrosion and maintain electrical conductivity.
- Temperature Control: Store batteries in a cool environment (between 5°C and 20°C or 41°F and 68°F) to prevent overheating and potential thermal runaway.
- Monitoring: Use thermal imaging or temperature sensors to monitor battery temperatures regularly, especially in environments where heat accumulation is possible.
- Software Updates: Ensure the Battery Management System (BMS) is updated and functioning correctly to monitor and manage battery parameters effectively.
By following these guidelines, you can help prevent thermal runaway and extend the lifespan of lithium-ion batteries.
