New energy battery cabinet aluminum plate damaged

What material is used in power battery aluminum trays?

Chalco's production of power battery aluminum trays mostly uses 6-series 6061 aluminum plate as the raw material for battery aluminum trays, which can meet the characteristics of high precision, corrosion resistance, high temperature resistance, and impact resistance to protect the battery core.

Why are aluminum plates prone to compression damage?

Furthermore, as the impact energy increased, battery cells were prone to compression damage. Additionally, under similar conditions, the impact resistance of aluminum plates significantly lagged behind that of steel substrates within battery systems.

Do battery pack bottom plates resist foreign object impacts?

In this study, it was observed that battery pack bottom plates of different materials exhibited varying capacities, resisting foreign object impacts. Results indicated that an impact energy of 150 J was equivalent to a 10 kg foreign object colliding with the bottom of the battery pack at a speed of ~20 km/h.

What causes battery failure in New energy vehicles?

This study investigated the failure characteristics of the battery system caused by bottom collision of new energy vehicles, analyzes the complex scenario conditions during the bottom impact process, and proposes a new energy vehicle bottom impact simulation method through the connection of data and mechanism models.

Which aluminum alloy is used in power batteries?

Aluminum alloy is a commonly used material for power batteries, and there is an urgent need to focus on research, development, and upgrading of products and alloy materials. At present, the conventional aluminum alloys used in power batteries mainly include 1-series, 3-series, 5-series, and 6-series.

What are the functions of a battery cover plate?

The cover plate has functions such as current conduction, pressure relief, fuse protection, and reduction of electrical corrosion. The material is changed from stainless steel to copper-aluminum composite material. The rupture disk is designed to play a major role in battery safety protection.
