On April 29, Huawei Digital Power Technology Co., Ltd. published a patent for “a charging pile and its control method”. The abstract shows that the charging pile includes a power conversion circuit for providing charging power for electric vehicles, and a controller for obtaining the temperature of the charging pile. When the temperature of the charging pile is less than or equal to the preset temperature threshold (for example, the temperature at the beginning of charging is low), the charging pile is controlled to be charged at a higher power than the full load; When the temperature rises above a preset temperature threshold, it charges with a smaller full load power.

The present application discloses a charging pile and a control method, wherein the charging pile includes: a power conversion circuit for providing charging power for an electric vehicle; a controller for obtaining the temperature of the charging pile; when the temperature of the charging pile is less than or equal to a preset value When the temperature threshold is set, the charging power is controlled to be greater than the full-load power; when the temperature of the charging pile is greater than the preset temperature threshold, the charging power is controlled to be the full-load power.

When the temperature of the charging pile is less than or equal to the preset temperature threshold, for example, in the initial stage of charging, the temperature of the charging pile is low, and the charging pile is controlled to charge the electric vehicle with a charging power greater than the full load power. Larger charging power for charging, increasing the charging speed. When the temperature rises above a preset temperature threshold, the electric vehicle is charged at a smaller full-load power. The minimum charging power provided by the application is full load power, and the average charging power during the charging process is larger than the traditional charging power, which improves the charging speed and shortens the charging time.
