Toyoda Gosei, the Japan-based auto component manufacturer has developed a battery case made of plastic to accommodate the large amount of batteries in electrified vehicles (EVs).

These battery cases are used on the Corolla PHV and Levin PHV that Toyota Motor Corporation began selling in China in March 2019. The company specialises in the manufacture of rubber and plastic automotive parts.

According to Toyoda Gosei, these cases increase the life of batteries by maintaining a gap between the stored batteries that allows them to be cooled by outside air brought in through ventilation holes in the sides. The cases are also insulated with internal conductors in the plastic to ensure safe performance. Toyoda Gosei will continue to utilise its expertise as a rubber and plastic specialist in efforts to optimise the cooling systems around batteries and reduce weight to contribute to improved automobile performance.
