Energy storage

A Battery Energy Storage System (BESS) is a technology developed for storing electric charges by using specially designed batteries. The underlying idea is that such stored energy can be utilized later.​ Lithium-Ion batteries are rapidly being introduced in these stationary energy storage applications as an alternative to commonly used Lead Acid batteries. The higher energy storage capability and better charge/discharge performance have led to a rapidly increased use of this technology outside the automotive industry. They have been crucial in the increased popularity of electric and hybrid vehicles. 

These batteries usually are very reliable over their lifespan. Still, unfortunately, in case of a failure, they can lead to severe consequences both for the integrity of the installation and the surrounding environment. 

When Li-ion batteries fail through short-circuiting, overcharging, high temperatures,
mechanical damage, and overheating, this might cause thermal runaway. Thermal
runaway occurs when a battery cell has reached the temperature at which the
temperature will continue to increase on its own, and the electrolyte catches fire.

As a solution to specific risks related to batteries, Dafo Vehicle has developed an early warning detection system solution. The system will detect potential battery failure at the earliest possible stage and take immediate action by cooling, using the suppression agent Forrex EV™. This will effectively stop, or delay, a potentially hazardous situation without the fire developing further.
