Back Ground

• Batteries of electric and hybrid vehicles generally require protective box designed to shield batteries.
• Protective Battery Box are high strength boxes formed of welded metals, which are heavy, prone to corrosion and have been found to be water penetrable at least the welds.
• Necessary to develop a Battery Box design that utilizes composite/Multi materials to lower the weight of the component, while improving the safety performance compared to conventional vehicle components

Overview

The Multi-material Battery Enclosure has high strength, is light weight and well suited for containing and protecting energy cells or batteries that adjusted to impact resistance, fire resistance, and fluid penetration prevention.

Features

• Develop design concept to utilize Teijin's capability of multi-material technology.
• Structural and frame resistant SMC is applied on cover and tray. Scalable design such as roll forming or extrusion process is applied on the metalic frame.
• Production feasibility has been confirmed by the full scale prototype part.
• Achievement of every key requirements which is based on GB standard has been already confirmed by the full scale prototype parts.
