Abstract

The invention relates to a power battery preheating method, a power battery preheating device, a vehicle and a storage medium. The power battery preheating device can preheat a power battery before charging so as to save charging time of the power battery. The power battery preheating method includes the steps of receiving a battery preheating instruction from a terminal; and supplying power to aheater through a vehicle-mounted battery of the vehicle according to the battery preheating instruction so as to preheat the power battery of the vehicle.

Description

technical field [0001] The present disclosure relates to the technical field of vehicles, and in particular, to a method and device for preheating a power battery, a vehicle and a storage medium. Background technique [0002] In recent years, under the strong support of national policies and the call for energy conservation and emission reduction, new energy vehicles have gradually become the darling of major car companies, and the penetration rate of electric vehicles and gasoline-electric hybrid vehicles has become higher and higher. For new energy vehicles, power batteries are the core components that power new energy vehicles. [0003] At present, in winter, especially in the north, the weather environment is relatively harsh and the ambient temperature is low, which leads to low charging efficiency of the power battery of new energy vehicles, especially when charging with high power, it will prolong the charging cycle and affect the life of the power battery. make an i...
