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. Where the safety temperature upper threshold is configured as a maximum temperature value for maintaining a normal performance of the battery. A heat preservation system for the battery of the vehicle by feeding electric power is further provided. 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.
