Abstract

The invention relates to a method for controlling preheating of a vehicle battery and further relates to a system for controlling preheating of the vehicle battery and a vehicle comprising the same. The method comprises the following steps that the residual electric quantity information and temperature information of the battery are obtained; the residual electric quantity of the battery is compared with a preset electric quantity; when the residual electric quantity of the battery is lower than the preset electric quantity, the temperature of the battery is compared with a preset temperature;when the temperature of the battery is lower than the preset temperature, a target charging pile is inquired and determined, and the distance from the vehicle to the target charging pile is obtained;the safe electric quantity needed for the vehicle travelling by the distance is calculated; through subtraction of the residual electric quantity of the battery and the safe electric quantity, the usable electric quantity, capable of being used for preheating the battery, in the battery is calculated; and through the usable electric quantity, the battery is preheated.

Description

technical field [0001] The present disclosure relates to a method of controlling preheating of a vehicle battery, a system for controlling preheating of a vehicle battery, and a vehicle including the system for controlling preheating of a vehicle battery. Background technique [0002] In today's world, vehicles have become an indispensable means of transportation for people's work and life. With the shortage of oil resources, the improvement of environmental protection requirements and the development of technology, more and more vehicles are driven by using electric energy in whole or in part. more common. [0003] A battery pack is a key component in a vehicle that drives a running vehicle by using electric energy in whole or in part. The battery pack needs to be recharged as it depletes. Temperature has a great influence on the charging performance of the battery. One of the conditions that the battery needs to meet while charging is to reach a certain temperature. Un...
