Valeo is developing battery thermal systems to guarantee the optimal operation of electric vehicles, their lifetime and reliability. Battery lithium-ion cells must be kept between 15 and 35°C to guarantee efficiency as well as durability, while all cells within a battery pack must be kept around the same temperature (less than 5K of variation).
Valeo has a long experience in this field and offers numerous applications for leading OEMs in hybrids, small electric vehicles (EV), plug-in hybrid electric vehicles (PHEV) and long range EVs. We design and manufacture suitable solutions (refrigerant, liquid cooling, air cooling) that cater to different uses.
