AI Technical Summary

Technical Problem

The existing battery module heating devices cannot maintain a constant temperature for a long time in a low temperature environment, which affects the stability of the module.

Method used

A battery assembly structure with heating and insulation function is designed, including a lower case, silicone sheet, heating sheet, epoxy plate, insulation mechanism, BMS mechanism and upper case. By setting the silicone sheet between the heating sheet and the lower case, an insulation mechanism is connected to the epoxy board to cover the battery cell, achieving long-term insulation in a constant temperature state.

Benefits of technology

It effectively prevents the rapid loss of heat after heating, realizes constant temperature insulation of the battery cell in a low temperature environment, avoids the reduction of the battery cell performance, reduces the heating time and number of times, and reduces the loss of electricity.

Abstract

The invention relates to the technical field of battery module heating and heat preservation equipment, in particular to a battery assembly structure with heating and heat preservation functions, which comprises a shell, a silica gel sheet, a heating sheet, an epoxy plate, a heat preservation mechanism, a BMS mechanism and an upper shell, the bottom wall of the lower shell is connected with the silica gel sheet, the top of the silica gel sheet is connected with the bottom of the epoxy plate through the heating sheet, and the epoxy plate is in contact fit with the bottom of a battery cell. The silicon sheet is arranged between the heating sheet and the lower shell, the epoxy plate is connected with a heat preservation mechanism so as to wrap the battery cell, the battery cell and the temperature switch are electrically connected with a BMS mechanism in the lower shell, the temperature switch is electrically connected with the heating sheet, and an opening in the top of the lower shell is connected with the upper shell through a bolt. The battery cell is coated by the heat insulation layer, so that heat generated after heating can be prevented from quickly losing through the lower shell, the device can be used for preserving heat of the battery cell in a low-temperature environment for a long time in a constant-temperature state, and the performance of the battery cell in the low-temperature environment is prevented from being reduced.
