There are several types of vehicle battery coolers, mainly including air cooling system and liquid cooling system.
1. Air cooling system: This system uses a fan to blow cold air to the battery to remove the heat from the battery surface. The air cooling system has a simple structure and is easy to maintain, but the cooling effect is limited in high temperature environments.
2. Liquid cooling system: The liquid cooling system uses a coolant (usually water or a special coolant) to circulate between the battery and the radiator to remove the heat generated by the battery. The liquid cooling system has a better cooling effect and can maintain the stability of the battery over a wider temperature range. Modern electric and hybrid vehicles often use this system to ensure the normal operation of the battery under extreme conditions.
1. Extend battery life: By controlling battery temperature, the cooler can effectively slow down the aging of the battery and extend the battery life, which not only reduces the frequency of battery replacement, but also reduces the long-term use cost.
2. Optimize battery performance: When the battery operates within its optimal temperature range, its performance is more stable and the charging and discharging efficiency is improved, thereby improving the overall performance of the vehicle.
3. Enhance driving safety: Battery overheating may cause battery failure or safety hazards. On-board battery coolers can mitigate these risks and ensure safe operation of the vehicle.
4. Improve energy efficiency: An effective cooling system allows the vehicle to operate with higher energy efficiency, which is especially important for electric vehicles because it directly affects their mileage.
