Dependable Reliability and Proven Safety

Since its founding, ELIIY Power has maintained a safety record of “no serious incidents caused by batteries.”

As lithium-ion batteries are superior to lead-acid and other rechargeable batteries in terms of their compact size, light weight and large capacity, their use has expanded across various fields such as mobile devices and electric vehicles. However, with their high energy density, damage or overcharging could lead to smoke or fire, posing the risk of a major accident.

Because ELIIY Power’s products are used in our daily living environment in houses, business offices and facilities, and as part of social infrastructure, we pursue development by first placing the highest priority on safety, in keeping with our philosophy that “the battery itself must be safe.”

A Safe Electricity Storage System Even in Case of An Emergency

Among the many electricity storage systems ELIIY Power has shipped, some have experienced secondary damage due to natural disasters or other unexpected accidents.
To provide safety and security even in case of an emergency , our electricity storage systems are equipped with battery cells based on stringent safety standards that prevent smoke or fire even when punctured, crushed or overcharged.
