Why is liquid cooling necessary? 

Liquid cooling for electric vehicle charging points means that the charge can be transferred to the vehicles much more quickly, without endangering the equipment or the driver using it. 

The faster an electric vehicle is charged, the greater the need for heat regulation. Increased output helps to charge the vehicle faster, but also generates a lot of heat. 

When the electricity flows from the charging point through the cable to the vehicle's battery, internal resistance to the increased electricity flow is responsible for generating this large amount of heat. This makes it necessary for the battery cells and battery pack to be cooled to prevent damage to the equipment and to ensure the vehicle driver's safety.

High power charging (HPC) only possible with liquid cooling

HPC rapid charging points use a liquid cooled cable to control the great heat caused by the charging speed.

 

Cooling takes place in the plug itself, with coolant flowing through the cable and into the contact between the car and plug.

 

As cooling takes place in the plug, the heat is almost immediately diverted as the coolant flows backwards and forwards between the cooling unit and the plug.

 

Liquid cooling means that the charging cable can be thinner and lighter, reducing the cable weight by about 40%.
