Why are lithium-ion batteries used in electric vehicles?

Lithium-ion batteries are currently used in most of the electric vehicles, and predominantly in 2W and 4W, because of their higher energy per unit mass relative to other electrical energy storage systems.

How to charge a lithium-ion battery?

Please refer and follow the standard instructions provided by the OEM Charger or Battery Manual. It is highly recommended to follow safe operation of Lithium Ion Batteries and standard protocols as per the guidelines of OEM. Any sort of battery or/and charger tampering or/abuse may not only degrade the life of the battery, but also can potentially lead to thermal runaway issues.

Give me any guidelines for Using Lithium-ion Batteries?

Use only lithium-ion cells with a designated protection circuit board and indeed with an approved charger. Do not short-circuit, overcharge, crush, drop, mutilate, penetrate with foreign objects, apply reverse polarity, expose to high temperature or disassemble packs and cells.

What are the standard guidelines for Charging Lithium-based Batteries?

Charge at a moderate temperature. Do not charge either at freezing temperature or at hot ambient conditions, and when the battery is directly exposed to the sun light or dust or water or humidity. Apply charging to an empty battery for a smaller amount of time before storing (40 to 50 percent SOC is ideal for the storage of the battery).

How does temperature affect my batteries?

Higher temperature, i.e. above 45°C can cause degradation to the battery and also reduce the efficiency of the battery, and the effect of higher temperature will be worse during the charging process compared to the discharging process. At lower temperatures, below 10°C, charging the battery to full capacity will be extremely difficult and discharging rates will not achieve the best of the battery potential. Hence, it is strongly recommended to charge the battery between 25°C to 35°C, and operate the battery for discharging between 15°C to 45°C.

How Fast Will My Lithium Battery recharge?

The answer depends on the total Amp Hour (AH) rating of your Lithium Battery pack and the current output rating of your charger. The recommended time for charging the Lithium battery is around 3 to 4 hours or higher, as faster charging can cause significant degradation to the life of the battery and also lead to thermal runaway issues
