Forced air cooling charging solution

When contemplating liquid cooling charging stations, one's thought may naturally gravitate towards industry giants such as ChargePoint. ChargePoint, boasting a formidable market share of 73% in North America, prominently employs liquid cooling charging modules for their DC charging products. Alternatively, Tesla's Shanghai V3 supercharging station, equipped with liquid cooling technology, may also come to mind.

ChargePoint Liquid Cooling DC Charging Station

Enterprises within the EV charging and battery swapping industry persistently innovate their technological approaches. Presently, charging modules can be categorized into two heat dissipation routes: forced air cooling route and liquid cooling route. Force air cooling solution expels heat generated by operational components via fan blade rotation, a method associated with increased noise during heat dissipation and the ingress of dust during fan operation. Notably, DC fast charging stations available on the market typically employ IP20-rated forced air cooling charging modules. This choice aligns with the imperative for rapid electric vehicle charging infrastructure deployment in its early stages within the country, as it affords cost-effective R&D, design, and production of charging facilities.

As we find ourselves ushering in the era of accelerated charging, the demands placed on charging infrastructure grow in tandem. Charging efficiency continually improves, operational capacity requirements intensify, and charging technology undergoes its necessary evolution. The application of liquid cooling technology to the charging domain has begun to take shape. A dedicated liquid circulation channel within the module facilitates the extraction of heat generated during the charging process. Furthermore, the internal components of liquid cooling charging modules remain sealed from the external environment, ensuring an IP65 rating, which elevates charging reliability and mitigates noise from charging facility operations.

Yet, investment costs become an emerging concern. The R&D and design costs associated with liquid cooling charging modules are comparably higher, resulting in a substantial increase in the overall investment required for charging infrastructure. For charging operators, charging stations represent the tools of their trade, and, in addition to operational revenue, factors such as product quality, service life, and after-sales maintenance costs assume considerable significance. Operators must seek to maximize economic returns throughout the life cycle, with initial acquisition costs no longer the primary determinant. Instead, service life and subsequent operational and maintenance expenses become the pivotal considerations.

Charging module heat dissipation techniques

Forced air cooling and liquid cooling represent distinct cooling routes for charging modules, both enhancing the performance, safety, and longevity of charging facilities by addressing issues of reliability, cost, and maintainability. Technically speaking, liquid cooling enjoys advantages in heat dissipation capacity, power conversion efficiency, and protective features. Nevertheless, from the vantage point of market competition, the key issue revolves around enhancing the competitiveness of charging equipment and catering to car owners' needs for convenient and secure charging. The cycle for achieving a return on investment and meeting investment demands becomes a pivotal consideration.
