Q3: How can we extend battery life through strategic measures and maintenance?

Q4: What are your strengths, export experience, and domestic and international use cases?

1. Enhance charge and discharge management
-Protect your battery by avoiding deep discharges. For instance, it's recommended to maintain lithium-ion battery levels between 20% and 80% to ensure optimal performance.
-Utilize an advanced intelligent BMS (Battery Management System) to precisely regulate the charging cutoff voltage, keeping ternary lithium batteries at or below 4.2V per single cell.
-Safeguard your battery's health by avoiding charging under extreme temperatures. Refrain from charging at temperatures exceeding 45ºC or below 0ºC.
2. Temperature management
-Incorporate an efficient heat dissipation system, such as air or liquid cooling, to maintain the battery's operating temperature between a safe range of 15 to 35ºC.
-Prevent overheating by avoiding prolonged high-rate discharges, for example, discharges greater than 1C.
3. Regular battery maintenance and monitoring
-Ensure balanced charging by having your BMS regularly calibrate any differences in individual cell voltages through passive or active balancing.
-For long-term storage, it's advisable to keep the battery charged at 50% and recharge every three months to maintain peak condition.
-Monitor the battery for signs of aging. Consider replacing it when capacity degrades by more than 20% or when the internal resistance increases by over 30%.
