Problems solved by technology

However, due to the risk of coolant leakage and the possibility of electrolyte leakage, and the possibility of external moisture entering the battery pack, water will accumulate inside the tray, and the accumulation of moisture will cause a short circuit in the battery pack, resulting in battery pack failure. In severe cases, it may even cause the battery pack to explode, causing a major safety accident

Abstract

The invention discloses a battery pack tray and a battery pack. The battery pack tray comprises two side beams which are oppositely arranged, and each side beam is internally provided with a cavity; at least one side beam is provided with a water absorption assembly, and the water absorption assembly comprises a water conveying piece and a water absorption piece; the cavity is filled with the water absorption part, the water conveying part is communicated with the cavity, and the water conveying part is configured to guide liquid in a battery pack into the cavity. According to the battery pack tray provided by the embodiment of the invention, when moisture exists in the battery pack tray, the moisture enters the cavities of the side beams through the water conveying pieces, and the water absorbing pieces in the cavities can play a role in absorbing and storing water, so that the moisture in the battery pack is reduced, and the risk of faults caused by short circuit of the battery pack is effectively reduced; and the use safety of the battery pack is improved.

Description

technical field [0001] The application belongs to the technical field of lithium ion batteries, and in particular relates to a battery pack tray and a battery pack. Background technique [0002] With the continuous increase of the promotion of new energy vehicles in my country, pure electric vehicles with green and environmental protection characteristics have become an inevitable trend in the future development of the automobile industry, which will gradually replace traditional fuel buses and become the daily means of transportation for ordinary people. The power source of electric vehicles is lithium-ion batteries. As an important component of electric vehicles, the safety performance of lithium-ion batteries has always been concerned. The battery tray is a key component of the battery pack that carries the battery module and connects the entire vehicle. Its mechanical properties and functional safety are very important, which puts forward higher requirements for the stru...
