The more power used to deliver faster charging, the more heat that is generated. Effective thermal management via liquid cooling deals with the heat and these systems need couplings or secure connectors in order to deliver reliable ongoing operation of EV charging stations and EV battery systems.

Attention to thermodynamic principles is critical yet the appropriate specifications for the components in charging stations are often poorly understood. Flow rate, temperature and pressure requirements, side load, chemical compatibility, seal and valve types, and overall quick disconnect structure and material (e.g., stainless steel, brass and newer high-performance engineered polymers) all have significant impact on liquid cooling system functionality. Purpose-built couplings support the quicker charging and fluid handling components and are often incorporated right alongside critical electronic equipment or components. These connectors or quick disconnects (QDs) are not all created equal...

Refresh yourself on calculations to apply and learn pitfalls to avoid in designing a system and specifying critical components like connectors.
