Liquid cooling tech used in high power charging solution for EVs

Liquid cooling tech used in high power charging solution for EVs
The electrical vehicle industry continues to gather pace. The market is forecast to grow to $731bn by 2027 (Source: IDTechEx). Several factors around vehicle charging will be crucial to underpin future growth. Increased availability of charging stations, for example, will be essential to enable more widespread access to charging and reduce consumer ‘range anxiety’. Yet equally important for growing consumer acceptance of Electric Vehicles (EVs) is the speed and efficiency of charging.
