EV batteries might experience reduced efficiency and power output in cold climates. A cooling system equipped with heating capabilities can preheat the battery before use, ensuring optimal operation even in low temperatures. Maintaining a stable temperature range ensures a predictable and consistent EV driving range.
Purely electric cars with high-performance batteries require more elaborate thermal management. The coolant- and refrigerant-based system, also called indirect battery cooling, has three circuits. Two of these have a low-temperature radiator, a coolant pump, a thermostat, and a coolant shut-off valve.
An electric vehicle battery is a rechargeable battery used to power the electric motors of a battery electric vehicle (BEV) or hybrid electric vehicle (HEV). They are typically lithium-ion batteries that are designed for high power-to-weight ratio and energy density.
New data has shown that exposure to heat and the use of fast charging promote the degradation of Li-ion batteries more than age and actual use, and that the average electric vehicle battery will retain 90% of its initial capacity after six years and six months of service.
Electric vehicles (EVs) necessitate an efficient cooling system to ensure their battery packs' optimal performance, longevity, and safety. The cooling system plays a critical role in maintaining the batteries within the appropriate temperature range, which is essential for several reasons we'll review in detail below.
One thing is already certain: Thermal management will play a vital role and this is an area where MAHLE can provide optimal support. The key components for high voltage thermal systems in electric vehicles include the battery cooler. Battery segments and cooling plates form a permanently fixed module.
