Abstract

The present invention relates to the field of battery charging and preheating devices, in particular to a self-heating type battery module fast charging external preheating device, including: a bottom plate and a battery; the bottom plate is composed of a device bottom plate and a battery bottom plate, and the bottom plate of the device is a groove-shaped structure. The battery bottom plate can be detachably fixed on the opening of the device bottom plate. There are several battery cell grooves on the battery bottom plate, and the battery is fixedly installed in the battery cell grooves; the automatic preheating device is installed in the device bottom The thermal device includes a heat-sensitive elastic part, an energy storage part and a heat conduction element; the heat-sensitive elastic part is arranged at the bottom of the groove of the bottom plate of the device, the energy storage part is fixed on the heat-sensitive elastic part, and the heat conduction element is arranged on the top surface of the energy storage part and between the bottom surfaces of the battery chassis. The preheating device of the present invention not only effectively utilizes the heat of the battery itself, but also realizes automatic rapid preheating according to the operating state of the battery based on the synergistic cooperation between the phase change material, the heat pipe and the thermal spring.

Description

technical field [0001] The invention relates to the field of battery charging and preheating devices, in particular to a self-heating type battery module fast charging external preheating device. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] In recent years, with the intensification of energy and environmental problems, green and efficient energy has gradually entered people's field of vision. Lithium batteries have attracted much attention in the electric vehicle industry. Due to the advantages of high safety, stable voltage distribution and low cost, more and more new energy automobile companies choose lithium iron phosphate batteries as vehicle power s...
