Abstract: The present disclosure provides a method and system for determining a pure electric available power and a vehicle, the method being applied to a vehicle including a fuel cell, the vehicle further including a battery pack and a motor, the fuel cell and the battery pack being electrically connected to the motor, wherein the method includes: monitoring a current travelling state of the vehicle and a current on-off state of the fuel cell; acquiring a maximum peak power outputted by the motor, a maximum output power of the battery pack and a starting-up power of the fuel cell; and according to the current travelling state, the current on-off state of the fuel cell, the maximum peak power, the maximum output power and the starting-up power, determining the pure electric available power. The present disclosure may quickly determine the pure electric available power, without complicated logical operation, and the operation states of the vehicle, the fuel cell system, the motor and the battery pack are taken into consideration at a same time, whereby the determined pure electric available power is closer to the actual available power.

Abstract: A method for heat preservation of a battery of a vehicle by feeding electric power is provided. This method includes: determining an expected vehicle usage time after charging of the battery of the vehicle has been completed and an expected activation time of a function of heating by feeding electric power for heating the battery; and controlling, when the expected activation time is reached, the vehicle to activate the function of heating by feeding electric power according to a current temperature of the battery and the expected vehicle usage time in order that the current temperature of the battery reaches a safety temperature upper threshold to complete heat preservation for the battery. According to the method in the present disclosure, an influence of low temperature on the battery will be avoided, and a waste of electric energy caused due to continuous heating of the battery may be avoided.
