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.
