Liquid Cooled 500A CCS Plugs

Brief Introduction

With the increase of charging rate, the technical limitations of cables and electrical connectors have gradually become prominent. DC fast chargers require larger conductors to carry higher currents, but this can also result in cables becoming bulky and inconvenient for users to use. Liquid cooled charging cables can effectively reduce the temperature at the DC contacts of cables and vehicle electrical connectors by using thinner wires and liquid cooling technology, while reducing the weight of cables, making them easier to operate and use.

 

Principle of heat dissipation for liquid cooled CCS plugs charging cable:
Drive the flow of coolant through an electronic pump. When the coolant passes through the Liquid Cooled 500A CCS Plugs cable, it takes away the heat from the cable and charging connector and returns to the fuel tank (for storing coolant); Then it is driven by an electronic pump to dissipate heat through a radiator.

 

 

Technical Specification

Contact resistance is an important quality indicator for the connection between cables and terminals, which determines the heat generation at the connection point. To reduce the heat generation at the connection point and improve the current carrying capacity, the Liquid Cooled 500A CCS Plugs cable and charging gun terminal produced by Senku are welded using ultrasonic welding.
Due to the mechanical collision involved in the process of inserting the charging gun, in order to fix the terminals and connecting wires, and to ensure the dustproof and waterproof performance of the gun head, some gun heads are filled with high thermal conductivity sealant inside.

Related Information

In addition to the liquid cooled charging gun, the liquid cooled module is also one of the core components of the liquid cooled charging system. The heat dissipation principle of the liquid cooling module is to circulate the coolant between the internal and external radiators of the liquid cooling charging module through a water pump, taking away the heat of the module.
