Abstract

The invention discloses a battery pack with thermal conducting adhesives. The battery pack comprises a shell and a plurality of battery units, wherein the shell is provided with a cooling device, the battery units are arranged in the shell, the thermal conducting adhesives with an electric insulation characteristic and a thermal conducting characteristic are arranged outside the battery units and are in contact with the outer surfaces of the battery units.

Description

technical field [0001] The invention relates to a battery pack filled with heat-conducting glue, in particular to a heat-conducting glue with electrical insulation properties and good heat conduction performance is filled between each battery unit of the battery pack, and then combined with air-cooled or water-cooled cooling. The device can indeed quickly reduce the working temperature of each battery unit, and can average the temperature difference between each battery unit. In addition, because the battery unit is covered with an elastic heat-conducting adhesive, it can also achieve functions such as absorbing vibration and reducing noise. battery pack. Background technique [0002] Due to the flammability of lithium metal in battery cells, especially lithium batteries, lithium batteries have safety concerns. When their purity is insufficient or improperly used, due to excessive internal resistance or instantaneous current Defects may cause overheating, which may cause co...
