EV batteries can be cooled using air cooling or liquid cooling. Liquid cooling is the method of choice to meet modern cooling requirements. Let’s go over both methods to understand the difference. Air cooling uses air to cool the battery and exists in the passive and active forms.
This need for direct cooling arises due to the significant heat generated by the high current flowing into the battery during fast charging. Effective battery cooling measures are employed to efficiently dissipate excess heat, thereby safeguarding both the charging rate and the battery from potential overheating issues.
Compatible with Battery: Coolants must work well with the type of battery in the vehicle. Meeting these requirements helps keep the battery cool, protects the system, and ensures the vehicle runs smoothly. It is also known as immersion and is usually used in heavy-duty and high-performance electronic devices.
Air cooling through natural ventilation is the cheapest and most simplistic mode of cooling for a battery pack but it does not provide sufficient cooling for most EV applications due to its low heat capacity and heat transfer coefficients .
By preventing excessive heat buildup, this cooling system significantly reduces the risk of battery fires and the release of toxic gases, thereby enhancing the safety of both the vehicle and its occupants. Another aspect of user safety is battery cell containment.
The most efficient technique of a battery cooling system is a liquid cooling loop, particularly designed to dissipate heat from the battery packs into the air. The cooling system’s heavyweight affects the EV range as it has to work more to neutralize the payoff load. It also leaves less room for other systems and materials.

At present, the mainstream cooling is still air cooling, air cooling using air as a heat transfer medium. There are two common types of air cooling: 1. passive air cooling, which directly uses external air for heat transfer; 2. active air cooling, which can pre-heat or cool the external air before entering the battery system.
Misting fans are not to be confused with misting systems. They''re not interchangeable, although they are both useful. A misting fan will add air circulation as well as air cooling to the mix. While spreading air with powerful fan blades, a misting fan expels fine water mist to activate evaporative cooling.

What will shorten battery life is temperature: If it gets hot, it will shorten the battery life. Best thing to do, if you are able, is to remove the battery while you''re at home and keep it somewhere cool. If it''s a Li-ion battery, then they don''t like to be completely discharged, so make sure you charge them regularly. Wikipedia:

The battery is not charging, and when I use an ohms meter between the alternator output terminal and the battery +, I read 7.5 ohms. When the motor is running I see 14.45v between the alternator terminal and ground. Rather than mess about with wiring looms etc. I would prefer to run a new cable from the alternator to the battery. Are there any ...
