How Long Does It Take to Charge the Lithium Battery of an Electric Vehicle?


Generally, a newly purchased lithium battery for an electric vehicle is brand new with a large capacity, so it will take a relatively long time to charge. It may not turn the indicator light off even after more than 10 hours of charging. Later, the charging time will get shorter and shorter. It will probably be reduced to about 6 hours after around 2 months, and then remain constant for about half a year. After that, the battery capacity will continue to decline, and it can be fully charged in 3 to 4 hours after 1 year. Of course, by then the battery is almost due for replacement or maintenance.


Regarding the charging time for the first charge, since the batteries of electric scooters have not been used when they leave the factory and have never gone through the processes of charging and discharging, it is necessary to ensure the normal operation of the batteries. Under normal circumstances, it is advisable to control the charging time to about 5 to 6 hours, just to fully charge the batteries. For subsequent uses, the charging time can be a bit longer.


After the first charge, although it is no longer the first charge strictly speaking, the second charge can also be considered as charging a new vehicle. At this time, you can let the battery power of the electric scooter run almost out and then conduct a long charging session, which can last for 8 to 9 or even 10 hours. The purpose is to allow a complete cycle of chemical reactions in the electric scooter.


Correct Charging Methods for Lithium Batteries of Electric Vehicles


  1. After buying the vehicle, the lithium battery should have about 80% of its power left. It should be charged as soon as you get home. The appropriate charging time is to continue charging for 4 hours after the charger indicator light changes. Do this three times.

  2. From then on, you should charge the battery every day, but do not charge it for too long. It is advisable to charge it for one hour after the charger indicator light changes. When charging, it is better to undercharge a little rather than overcharge. Otherwise, the battery may bulge and swell due to water loss, causing irreparable damage to the lithium battery.

  3. Do not let water enter the lithium battery box to prevent the batteries inside the casing from short-circuiting.

  4. Once a month, completely discharge the whole battery group (ride until the undervoltage indicator light is on), and then charge it continuously for 12 hours.

  5. If possible, swap the individual cells in the whole group of electric vehicle lithium batteries. For batteries that have passed the warranty period, add 3 to 4 milliliters of deionized water to each cell every three or four months.

  6. Once you find that the charger does not turn green or turns green immediately after starting to charge, you must check whether there is a problem with the charger or water loss.


Correct Usage Methods for Lithium Batteries of Electric Vehicles


The activation of lithium batteries in electric vehicles does not require any special methods. The lithium batteries will be activated naturally during the operation of the electric vehicle. If you deliberately use the widely spread method of charging for 12 hours for the first three times to activate the batteries, it will be in vain and have no effect.


When the lithium battery in the electric vehicle shows a low power warning during driving, you should charge the lithium battery as soon as possible.


Charge the battery according to the standard time and procedures, even for the first three times. In particular, do not conduct an extremely long charging session that exceeds 12 hours.
