Fully Liquid-Cooled Supercharger Brief Analysis

New Energy Vehicle Pain Points

Despite the rapid growth of electric vehicles, the persistent challenges faced by consumers, such as the difficulties in charging, long charging times, and limited driving range, have continued to hinder their development. These issues have repeatedly become hot topics, highlighting the critical obstacles that need to be addressed in the advancement of electric vehicle technology.

Fully Liquid-cooled Supercharger

The statement “5 minutes of charging for a 300-kilometer range” has now become a reality, seemingly addressing the issue of “slow charging” in electric vehicles. Liquid-cooled fast-charging technology, as a novel solution to the challenges of electric vehicle charging, has emerged as a focal point in the industry. Liquid-cooled fast charging employs a cooling system that utilizes liquid-cooled plates in the battery section and includes a liquid circulation channel between the cables and the charging gun. Within this channel, a cooling fluid is introduced to dissipate heat efficiently. This cooling fluid is circulated by a power pump, effectively removing the heat generated during the charging process.


A fully liquid-cooled design offers superior heat dissipation, reduced noise levels, and extends equipment lifespan to 10-20 years or more. The use of fast-charging stations achieves a charging success rate of over 99%. The comprehensive liquid-cooled fast-charging architecture can cater to the charging requirements of various vehicle models, enabling on-the-spot charging, power sharing, and maximizing the fulfillment of vehicle charging needs. In the future, it will support smooth integration of both AC and DC power with energy storage, facilitating intelligent peak shaving, reducing the need for grid modifications, and enhancing the efficient utilization of electrical resources.


The fully liquid-cooled fast charging system delivers a higher charging current and faster charging speeds. The output current of the charging station is constrained by the charging gun cable, which uses copper conductors for electrical conduction. The heat generated in the cable is directly proportional to the square of the current. Therefore, with higher charging currents, the cable generates more heat. To reduce cable heating and prevent overheating, it becomes necessary to increase the cross-sectional area of the conductors, which in turn results in a heavier charging gun cable. 


Currently, the national standard 250A charging gun typically employs an 80mm² cable, making the charging gun relatively heavy.


In the future, if higher current charging is to be realized, a more integrated battery system and a more efficient liquid-cooled heat exchanger system and liquid-cooled charging gun will be required at the charging source.
