The invention discloses a low-voltage platform vehicle public charging pile capable of realizing fast charging, which comprises a public charging pile body and an EMI filter, the output end of the EMI filter is electrically connected with an anti-surge, the output end of the anti-surge is electrically connected with a rectifier, the output end of the rectifier is electrically connected with a PFC power corrector, and the output end of the PFC power corrector is electrically connected with a power supply. The output end of the PFC power corrector is electrically connected with an isolation DC converter and an auxiliary power supply. Through the arrangement of the public charging pile body, the EMI filter, the surge prevention, the rectifier, the PFC power correction, the isolation DC conversion, the high-frequency rectifier, the filter, the auxiliary power supply, the control circuit and the isolation communication, the problems that the output voltage range of the existing public charging pile is 200V-700V, and a passenger vehicle with a voltage platform lower than 200V cannot use the public charging pile for charging; a solution is provided for solving the problem that the vehicle owner cannot supplement power in case of outdoor power shortage, the charging speed is improved, and the charging time is shortened.

    本发明公开了一种低压平台车辆可实现快充能使用公共充电桩,包括公共充电桩本体和EMI滤波,所述EMI滤波的输出端电性连接有防浪涌,所述防浪涌的输出端电性连接有整流器,所述整流器的输出端电性连接有PFC功率校正,所述PFC功率校正的输出端分别电性连接有隔离DC变换和辅助电源。本发明通过公共充电桩本体、EMI滤波、防浪涌、整流器、PFC功率校正、隔离DC变换、高频整流器、滤波、辅助电源、控制电路和隔离通信的设置,解决了目前公共充电桩输出电压范围为200V‑700V,电压平台低于200V的乘用车将无法使用公共充电桩进行补电,车主将面临户外缺电无法补电的风险,针对此类问题给出了解决方案,并提高了充电速度缩短充电时间的问题。
