Problems solved by technology

However, the high-voltage support structure of the existing battery pack is that the protective support is clamped and installed on the end plate, and glue is applied between the end plate and the battery pack. row, affecting the heat dissipation effect of the busbar
Moreover, the high-voltage support structure of the existing battery pack is prone to produce water film, which will damage the insulation withstand voltage strength of the battery pack and cause the insulation failure of the module.
Therefore, the existing battery pack can no longer meet the urgent requirements of the current industry development for the dielectric strength and safety performance of the battery pack

Abstract

The invention relates to the technical field of batteries, in particular to a battery pile, a battery module and a battery pack. The battery pile comprises a plurality of batteries, an end plate and a protective support, wherein the plurality of batteries are arranged in a first direction; the end plate is arranged at the end part of the battery pile in the first direction; the protective support is arranged on the end plate; the protective support has a first surface and a second surface which are adjacent, the end plate has a third surface and a fourth surface which are adjacent, the first surface and the third surface are oppositely arranged, and the second surface and the fourth surface face the battery in the first direction; the fourth surface is provided with an adhesive layer; the protective support has a first gap at the junction of the first surface and the second surface, and / or the end plate has a second gap at the junction of the third surface and the fourth surface; and a first combination or a second combination or a third combination forms a groove, an opening of the groove faces the battery in the first direction, the first combination comprises the first notch and the third face, the second combination comprises the second notch and the first surface, and the third combination comprises the first notch and the second notch.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack, a battery module and a battery pack. Background technique [0002] With the increasingly stringent requirements of the country and industry on the safety of new energy vehicles and battery packs, especially when the battery pack is in a hot and humid environment, the dielectric strength of the battery pack should be improved to reduce the risk of insulation failure of the battery pack. Improve the module environment and improve the module security performance. However, the high-voltage support structure of the existing battery pack is that the protective support is clamped and installed on the end plate, and glue is applied between the end plate and the battery pack. row, which affects the heat dissipation effect of the busbar. Moreover, the high-voltage support structure of the existing battery pack is prone to produce water film, which destroys the insulatio...
