Abstract

Embodiments of the present invention provide a battery pack heating device and a control method. In the embodiment of the present invention, the heating device for the battery pack is installed outside the vehicle in a portable manner, and includes: an electric energy conversion assembly, including an energy storage device, a first switch group, and a second switch group; a heating interface, the heating interface passes through the first A switch group is connected with the energy storage device to form a first heating circuit, and the heating interface is connected with the energy storage device through the second switch group to form a second heating circuit, and the heating interface is used for connecting with a The battery pack of the vehicle is connected; the heating control module is used to control the direction of electric energy transfer between the battery pack and the energy storage device. Therefore, the technical solutions provided by the embodiments of the present invention can solve the problem of low heating efficiency existing in the indirect heating method in the prior art.

Description

【Technical field】 [0001] The invention relates to the technical field of batteries, in particular to a battery pack heating device and a control method. 【Background technique】 [0002] Intelligence and electrification are one of the important development directions in the field of intelligent transportation, especially in the field of electrification. With the advancement of materials and technologies, the energy density of battery packs is getting higher and higher, and vehicles are also using various types of batteries. As an energy source, compared with traditional vehicles that mainly use fossil fuels as energy sources, more and more modern vehicles use battery packs represented by lithium batteries as energy sources. The research data shows that in the environment of minus 30 degrees, the charge and discharge performance of the battery pack is basically zero, so the study of the battery pack is very important to improve the adaptability of the vehicle to the environment...
