Provided is a charging controller that controls a process of charging a battery from an external power source. When an outside air temperature is equal to or lower than a predetermined temperature, the charging controller charges the battery from a time earlier than a scheduled time of use of the battery by a predetermined time until the scheduled time of use. Thus, even when the outside air temperature is equal to or lower than the predetermined temperature, the temperature of the battery has been raised by heat generated during the charging by the time of use of the battery.

Acquiring a second temperature of a rotor at a current sampling time according to system parameters and a first temperature of the rotor at a previous sampling time, and estimating a third temperature of the rotor at a next sampling time according to the first temperature and the second temperature, and stopping the self-heating of the traction battery when the third temperature reaches a demagnetization temperature of the rotor. Whether to stop the self-heating of the traction battery is determined by estimating a rotor temperature under the self-heating condition, and comparing the rotor temperature with the demagnetization temperature of the rotor, and thus the self-heating control of the traction battery is realized.

An ECU of a fuel cell vehicle determines whether the vehicle travels on an uphill road or not. When determining that the vehicle travels on the uphill road, the ECU performs at least one of a temperature reduction control for reducing the temperature of a fuel cell stack and a humidification control for increasing the water content of the fuel cell stack, by the time the vehicle reaches the uphill road.

This application provides a charging time estimation method and apparatus, and a storage medium. The method includes: obtaining a current temperature of a to-be-charged device and a current state of charge (SOC) of the to-be-charged device in a calculation period, and obtaining a required current of the to-be-charged device based on the current temperature and the current state of charge; and determining a charging current of the to-be-charged device; and obtaining a charging time.
