1. Charge it every day
Even if your electric vehicle's lithium-ion battery can last for 2 to 3 days on a single charge, it is still recommended that you charge it every day. This is because a used lithium-ion battery is in a shallow cycle state, and charging it daily will extend the battery's lifespan.
2. Charge in a timely manner
Because lithium-ion batteries in electric vehicles undergo sulfation after discharge, timely charging can remove minor sulfation. Therefore, lithium-ion batteries should be charged as soon as possible after use to keep them at a full charge level.
3. Periodic deep discharge
Performing a deep discharge periodically can also help "activate" the battery, slightly increasing the capacity of lithium-ion batteries. A common method is to periodically perform a complete discharge. A complete discharge is achieved by riding a bicycle under normal load conditions on a flat road until the first undervoltage protection is triggered.
After the battery experiences its first undervoltage protection event, once the voltage returns to a normal level, a full charge at this point will improve the battery's capacity. It's crucial to note that you should never use a lithium-ion battery during its first undervoltage protection event, as this can severely damage the battery.
4. Use the original charger whenever possible.
Generally, lithium-ion battery chargers from different manufacturers have individual requirements, so do not change the charger if you are not sure.
