For owners of electric vehicles, they are eager for fast charging. The liquid-cooled supercharging technology can enhance the user experience and guarantee the safety of supercharging, which is expected to be the development trend of the industry.
DC charging pile, also known as fast charging pile, consists of three main parts: charging module, charging connector and cable, and main control board. When high power charging is carried out, the peak current can reach 600A, and the heat generated by the high current charging process is more, so the charging pile heat management requirements are also more stringent. Heat dissipation is a problem that needs to be solved when charging piles are used for high power fast charging.
Charging pile accelerated construction, is expected to drive the charging connector market demand. Connector is the carrier of electrical connection between charging pile and electric car, which can realize the communication connection between charging pile and car, and is an essential part for charging pile to realize charging function.
FAFA-E has developed a water-cooled portable charger for electric vehicle charging. Compared with the traditional DC charging connector and cable, this product adds cooling pipes to the connector, cable and charging post loop, adds coolant to the internal pipes of the cable, and drives the coolant circulation flow through the power pump, which in turn brings out the heat, such an operation mechanism prevents the charging system from overheating problems caused by high current.
The liquid-cooled cable generates a lot of heat during operation, and it gets hot due to carrying high currents. The high-power liquid-cooled charging connector is driven by an electronic pump to circulate the coolant and take away the heat from the cable and charging connector, back to the tank (where the coolant is stored), and then driven by an electronic pump through a heat sink to dissipate the heat. The charging connector and the cable work in this cycle, so that the small cross-sectional area of the cable can be loaded with high current, to achieve the requirements of low temperature rise.
