Abstract

The invention relates to an electric vehicle with a thermal management system. The electric vehicle is provided with at least one electric drive (28), a traction battery (12) and at least one thermalenergy source (14), wherein the traction battery (12) can be electrically coupled with the drive (28) and the thermal energy source (14) can be thermally coupled with the traction battery (12). The invention further relates to a method for adjusting the temperature of the traction battery (12) of the motor vehicle (1).

Description

technical field [0001] The invention relates to an electric vehicle with a thermal management system. In particular, the invention relates to a motor vehicle equipped with a thermal energy source and having at least one electric drive. Furthermore, the invention relates to a method for regulating the temperature of a traction battery of a motor vehicle. Background technique [0002] Electric vehicles powered by battery packs or accumulators usually have a traction battery, by means of which the electrical energy required for the electric drive can be stored. The life and capacity of this traction battery is dependent on temperature. The maximum efficiency and full charge capacity of such traction batteries are usually only obtained within a narrow temperature range. In particularly cold weather conditions, most commercially available traction batteries, such as lithium-ion batteries, have an increased internal resistance which leads to a loss of capacity. [0003] Due to...
