What are the correct methods for charging lithium-ion batteries in electric vehicles?
Electric vehicles use environmentally friendly and lightweight lithium-ion batteries, which have outstanding features such as large capacity, long lifespan, maintenance-free operation, light weight, and no pollution. The charging method for electric vehicle lithium-ion batteries is as follows:
1. Charge according to the standard time and procedure, even for the first three times.
2. When the lithium-ion battery of an electric vehicle displays a low battery warning while driving, the lithium-ion battery should be charged as soon as possible.
3. Lithium-ion battery electric vehicles do not require special activation methods; the lithium-ion battery will activate naturally while the electric vehicle is in motion.
4. Use the vehicle's dedicated charger for charging. First, insert the charger's output plug into the corresponding battery charging socket, and then insert the charger plug into the AC power socket. Observe the indicator lights to determine the charging status (generally, a red light indicates that it is charging, and a green light indicates that it is basically fully charged. The more it discharges, the longer it takes to charge).
5. After the charger indicator light turns green, continue charging for about 1-2 hours, then stop charging.
What issues should be considered when charging lithium-ion batteries for electric vehicles?
1. Do not activate lithium-ion batteries.
Do not charge lithium-ion batteries for more than 12 hours for the first three times. Lithium-ion batteries have no memory effect and can be charged whenever needed.
2. Battery charging
Use the charger specified by the manufacturer to charge the battery. When charging, make sure that the charger model is compatible with the lithium-ion battery model.
3. Prevent high-temperature charging
Do not charge lithium-ion batteries in environments with temperatures exceeding 40 degrees Celsius, as high temperatures will cause battery capacity to degrade.
4. Charge in a timely manner
For lithium-ion batteries, try to charge them as needed to avoid letting the battery run low on voltage before recharging, which can greatly extend battery life.
5. Storage
When the battery is not in use for an extended period, disconnect it from the vehicle and periodically recharge it to prevent self-discharge or over-discharge by the protection board.
