Do lithium batteries in electric vehicles need to be completely depleted before being recharged?

Lithium batteries in electric vehicles do not need to be completely depleted before being recharged.

Precautions for using lithium batteries:

1. Since lithium batteries are non-memory batteries, customers are advised to regularize the battery after each day of regular charging or. recharging will significantly extend battery life.

Do not charge the battery each time until it is no longer discharged. It is not recommended to discharge more than 90% of the battery capacity. When the undervoltage indicator light of the electric vehicle lights up when the electric vehicle is stopped, it should be charged in time.

2. Lithium batteries not only may cause fires or explosions during the manufacturing process, but also may burn or explode during transportation or use after being assimilated.immediately on electric vehicles. There are many reasons. The main reason is that there are defects in the manufacturing process of lithium batteries, which lead to spontaneous combustion under severe shock, overcharge (the protection plate does not have a cut-off function), excessive temperature and others. terms.

Lithium electric vehicle charging instructions

Lithium batteries have high energy density, small size and light weight. incomparable lead acid batteries.

The battery has some remaining power before leaving the factory, and it can also be used for short-distance trips after the electric vehicle is sold. After the first trip, the battery must be charged for the first time. It is recommended to carry out the first charge for a longer duration (8 to 12 hours).

The battery should be charged in time after use and should not be stored at a loss. If the battery has not been used for more than two months, the battery should be fully charged. If the battery is left for more than 5 months, it must undergo a charge and discharge cycle.

In order to ensure the safety of lithium-ion batteries, there are a series of safety protection designs from battery cells, modules to battery systems to prevent the battery from overcharging, overcharging, overdischarge and overheat. and to alert and protect quickly.

Method of charging the lithium battery of an electric vehicle: use the special chargercial provided by the manufacturer and charge it as you go.

1. When charging for the first time, it is the same as normal charging, no special treatment is required. It can be charged for eight to twelve hours.

2. You must use a special charger provided by the lithium battery manufacturer for charging. When charging, first connect the charger output port to the battery, then connect the charger to the power supply.

3. Since lithium batteries do not have a memory effect, they can be charged at any time, which is good for battery life. It is recommended to charge for eight to twelve hours each time. the longest duration should not exceed one day.

4. If not used for a long time, the lithium battery should be charged for two hours every two months, otherwise the battery performance will be reduced. Furthermore, arePlease do not charge the battery when it is completely discharged. It's best to charge it as you use it and charge it superficially.Put it superficially.

Notes on charging lithium batteries for electric vehicles

1 The battery does not need to be "activated"

Lithium batteries do not need to be charged for more than 12 hours the first three times, and lithium batteries have no memory.

2. Charging the battery

Use the charger specified by the manufacturer to charge. When charging, pay attention to whether the charger model matches the battery model.

3. Avoid charging at high temperatures

Do not charge electric vehicle lithium batteries in an environment where the temperature exceeds 40°C. battery capacity diminute.
