Abstract

The present invention discloses a method and an apparatus for determining the remaining heating time for heating a power battery to achieve a rechargeable temperature, and relates to the field of electric vehicles. The method comprises: acquiring the initial battery temperature of an electric vehicle power battery when the electric vehicle power battery requires charging; comparing the initial battery temperature and the allowable charging temperature; determining the total heating time for heating from the initial battery temperature to the allowable charging temperature of the electric vehicle power battery if the initial battery temperature is less than the allowable charging temperature; and during the heating process of the electric vehicle power battery, according to the temperature change and the total heating time of the electric vehicle power battery, determining the remaining heating time. According to the present invention, with the method and the apparatus, the remaining heating time for heating the electric vehicle power battery from the non-rechargeable temperature to the rechargeable temperature can be determined.

Description

technical field [0001] The invention relates to an electric vehicle, in particular to a method for determining the remaining heating time of a power battery heated to a rechargeable temperature and a related device. Background technique [0002] Lithium-ion power battery has become the most widely used power battery for domestic electric vehicles, thanks to its high safety and economy. But it has a significant disadvantage, that is, poor low-temperature performance, especially low-temperature charging performance, such as lithium iron phosphate batteries, which are generally considered to be below 0°C, and charging is prohibited, because low-temperature charging will affect its safety and cycle life. Therefore, the lithium-ion power battery system used in electric vehicles is generally designed with a heating system to heat the power battery when charging at low temperature, and then start charging after it reaches the allowable charging temperature, but the existence of the...
