Correct charging method for lithium-ion battery packs in electric vehicles
● Avoid prolonged or deep charging, as this may lead to overcharging. Lithium-ion batteries and chargers automatically stop charging once the battery is fully charged; there is no continuous trickle charging for 10+ hours as claimed by nickel-cadmium chargers. In other words, leaving your lithium-ion battery on the charger after it's fully charged is pointless.
● Avoid overcharging and over-discharging. Over-discharging or self-discharge reactions at low voltage can cause the lithium-ion active materials to decompose and be destroyed, and may not be reversible. Any form of overcharging of a lithium-ion battery will severely damage its performance and may even lead to an explosion. Overcharging of lithium-ion batteries must be prevented during the charging process.
●Since lithium-ion batteries are memory-free, it is recommended that customers regularly charge or top up the battery pack after each or daily ride. This will significantly extend the battery pack's lifespan. It is advised not to ride until the battery pack can no longer discharge before recharging, and it is not recommended to discharge the battery beyond 90% of its capacity.
●When starting an electric vehicle, riding on a steep slope, a dirt road, or in strong headwinds, it is recommended that customers use pedal assistance to maximize the lifespan of the battery and motor.
● The capacity of electric vehicle lithium-ion battery packs is measured at a normal temperature of 25°C. Therefore, a slight decrease in battery capacity and driving range during winter is considered normal. It is recommended to charge the battery pack in warmer environments during winter to ensure it is fully charged.
● When not riding or parked, it is recommended that customers disconnect the lithium-ion battery pack from the electric vehicle or turn off the power switch. This is because the motor and controller consume power even when not in use, and this helps prevent wasting electricity.
● Lithium-ion battery packs have some remaining charge before leaving the factory, allowing for short-distance riding even after the electric vehicle is sold. After the first ride, the battery must be charged for the first time, and it is recommended that the first charge be carried out for a slightly longer period of time.
