CPC provides liquid cooling solutions that can help address challenges to electric vehicle (EV) adoption. Liquid cooling offers benefits over air cooling like higher heat transfer capacity and a fully enclosed design. Introducing liquid cooling into EV fast charging requires considering equipment sizing, modularity, material compatibility, and easy maintenance. CPC's non-spill quick couplings and modular product offerings aim to meet the unique needs of liquid-cooled EV charging applications. Liquid cooling can help amplify the journey to wider EV use.

EV CHARGING WAYS
Image from evbox.com
• AC for the Grid and DC for the Battery
• AC charging – onboard charger helps in DC
conversion.
• DC allows high power & ultra-fast charging
• AC charging is almost flat/constant rate
• DC charging follows a degrading curve and
requires precision control electronics.

Editor's Notes
Additionally, charging stations are often located in high-traffic areas.
Long charging time.
Charging owners must serve more customers to benefit from the infra.
