Concentration of high-voltage fast charging

Liquid cooling technology is expected to be popularized to combat the problem of heat generation during high-power fast charging
The high charging power provided by 800V causes high heat generation and overheating problems in the charging system, which is an important challenge for the current fast charging of electric vehicles.
Traditional air cooling technology can hardly meet the heat dissipation requirements of charging stations with hundreds of kilowatts, while liquid cooling is more suitable for high-speed charging and discharging scenarios. Liquid cooling technology installs a special liquid coolant between the cable and the charging gun, which is driven by costa rica number data a pump to circulate in the cable and the charging gun, carrying away the heat during the charging process and returning to the radiator of the liquid cooling source, thereby increasing the power transmitted by the cable and achieving high-speed charging.
Compared with the traditional air cooling mode, liquid cooling mode has the characteristics of high safety, fast charging, long service life, low operating and maintenance costs. For example, Huawei's 600kW full liquid cooling solution, although it has a relatively high initial investment cost, can reduce secondary investment, and the total cost of ownership TCO is reduced by about 40%.
