1. Overcharging and Over-discharging: When using lithium-ion and polymer batteries for electric vehicles, it is crucial to avoid overcharging and over-discharging. After fully charging, allow for an additional hour of supplementary charging, but avoid overcharging and over-discharging. Overcharging and over-discharging can cause permanent damage to the positive and negative electrodes. Over-discharging causes the carbon layer structure of the negative electrode to collapse, preventing lithium ions from inserting during charging; overcharging causes excessive lithium ions to embed into the carbon structure of the negative electrode, resulting in some lithium ions never being released.
2. Charger: Use the specially designed charger.
3. Short circuit: Short circuits can easily occur during charging. These include internal and external short circuits, so extra caution should be taken.
4. Storage requirements: Polymer batteries: Store in an environment with a temperature of 25±5℃ and humidity not exceeding 50%;
Lithium-ion batteries: in an environment with a temperature of 20±5℃ and a humidity not exceeding 50%.
When storing or not using electric vehicle lithium-ion and polymer batteries for extended periods, they should be fully charged and placed in a dry, cool place. It should be noted that after a period of storage, the battery enters a dormant state, at which point its capacity is lower than normal, and its usage time is also shortened; this is normal.
