Safety Device (CID : Current Interrupt Device)

If external impact is applied or when it is overcharged, over-current and gas are occurred, leading to increase in temperature and pressure. Components are required for releasing gas when the pressure is increased in the cell to prevent explosion. Cap assembly, an essential component for the safety, plays such role.

ESS (Energy Storage System)

We are making terminal bolt, which is the core component used as output terminal on high-density / high-output ESS product. By establishing manufacturing infrastructure for entire process such as forging press, NC processing, and surface processing, we focus on quality management and stable delivery and supply.
