In recent years, with the rapid development of the new energy vehicle industry, the demand for charging infrastructure has also surged dramatically, prompting a continuous emergence of various new technologies and products. Charging piles, as one of the key infrastructures, have garnered widespread attention. 40kW charging pile modules, liquid-cooled ultra-charging solutions, and bidirectional charging modules have become hot topics, driving the progress and innovation of the industry.
Liquid-cooled charging piles are devices that use liquid cooling technology to charge electric vehicles. Compared to traditional air-cooled charging piles, liquid-cooled charging piles have better heat dissipation effects during high-power charging, which can improve charging efficiency, extend the lifespan of charging equipment, and ensure the safety of the charging process. Today, we mainly share the working principle of liquid-cooled charging piles and the role of the core component, the liquid cooling charging module.
The core of a liquid-cooled charging pile is the liquid cooling system. The liquid cooling system typically consists of coolant, cooling pipes, a cooling pump, and a radiator. Its working principle is as follows:
Heat Transfer
The heat generated by the charging pile during operation is transferred to the coolant through thermal conductive materials.
Coolant Circulation
The coolant, driven by the cooling pump, circulates through the cooling pipes, carrying the heat to the radiator.
Heat Dissipation
The radiator releases the heat carried by the coolant into the external environment, reducing the temperature of the coolant.
Coolant Return
The cooled coolant flows back into the charging pile, continuing to absorb heat.
The liquid cooling module plays a critical role in the charging pile, greatly enhancing the efficiency of energy transfer during the electric vehicle charging process. Its built-in cooling system efficiently transfers the heat released by the electric vehicle battery to the liquid cooling system of the charging pile for dissipation, thereby effectively optimizing energy transfer efficiency.
Moreover, the liquid cooling module system adopts a compact dust-proof and heat exchange design, effectively reducing the gaps between electrical components, lowering the risk of electrical short circuits caused by corrosion and external factors, and thereby reducing the failure rate of the system.
The liquid-cooled charging module boasts strong adaptability and protective performance. By using coolant for heat dissipation, and with its unique internal design to prevent electronic components from being directly affected by dust, salt spray, or water vapor from the external environment.Therefore, liquid-cooled charging modules can perform well under harsh conditions such as high temperature, high humidity, high salinity and dust, such as in extreme environments such as the tropics, seaside or mining areas. Its high protection level ensures the safe use of charging pile equipment.
Maxwell's liquid cooling solutions are designed to meet stringent environmental requirements. The product line includes 40kW and 60kW liquid-cooled charging modules, aimed at advancing the development and application of electric vehicle charging infrastructure.
With an energy conversion efficiency exceeding 95%, the liquid cooling charging system minimizes energy waste, offering eco-friendly and energy-saving benefits.
Additionally, the liquid cooling module enables fast charging, significantly enhancing the convenience and efficiency of electric vehicle use. By playing a key role within charging stations, it not only boosts charging efficiency but also ensures equipment safety, further improving the user's charging experience.
