Energy storage

How can you safely store lithium-ion batteries?

To reduce greenhouse gas emissions and decarbonize the power system, energy storage is vital. Today several energy storage solutions are available. A Battery Energy Storage System (BESS) is a technology developed for storing electric charges using specially designed batteries. The underlying idea is that such stored energy can be utilized later.

Lithium-ion batteries

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 failure, they can lead to severe consequences for the integrity of the installation and the surrounding environment. 

Dafo Energy Storage Protection

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, and the electrolyte catches fire.

Dafo Vehicle has developed a high-sensitivity sensor solution that works as an early warning detection system as a solution to specific risks related to battery storage containers. A plug-and-play solution able to make an alarm in the venting phase before the battery goes into thermal runaway. 

The system will come with coded cabling, so each component has its place. The CO sensors will be pre-programmed at 50 ppm for alarms, and the system can handle four sensors simultaneously. In the event of an alarm, the CO sensor will send a signal to the control board, which sends out an SMS to the user, and the alarm system/strobe lights will be activated.
