When the temperature of the battery is in a higher or lower state, and the corresponding heating module and the heat dissipation module still cannot reach the normal working temperature range within a limited time, the battery output control module outputs control to cut off the circuit so as to prevent the product from being damaged under the condition of extreme environmental temperature.
