Abstract: This application discloses a charging pile and a charging pile control method. The method includes: obtaining a first temperature of at least one charging apparatus that is in a first state and that is in a charging pile; obtaining a second temperature of at least one charging apparatus that is in a second state and that is in the charging pile, where the second state is a sleep state; calculating a temperature difference between the second temperature and the first temperature; determining whether the temperature difference is greater than a first threshold, where the first threshold is an upper-limit temperature of the temperature difference; and when the temperature difference is greater than the first threshold, starting a heat dissipation fan of the charging apparatus that is in the second state.

Abstract: This application relates to the field of electronic device technologies, and provides an electronic component with an enclosure frame, a circuit board with an electronic component, and an electronic device, to effectively protect the circuit board from being corroded, thereby prolonging a service life of the electronic device. This application is applied to a charging pile for charging a new energy electric vehicle. An electronic component with an enclosure frame includes an enclosure frame and an electronic component. The enclosure frame defines a cavity that is closed or that has one open end; when the electronic component with an enclosure frame is connected to a circuit board, the enclosure frame and the circuit board can define a cavity that is closed or that has one open end.
