Project Description

Challenge
Previous VRLA battery capacity deployed at off-grid site offered only 2-4 hours backup after several short cycles. Operator contacted Incell in order to reduce diesel and electricity consumption on generator (DG) by reducing its operation to 6hrs per day. Additionally, the new battery system should sustain a cycle life superior to 5 years. Lastly, the site required supplementary battery SoC (10%) in case the DG failed to start properly.

Solution
Incell provided a compact solution that cycled the battery system 4-5 times per day, which enabled the batteries charge during 1.5 hours and discharge during 4-5 hours. The proposed battery can be cycled over 7500 times. Specific DoD (Depth-of-Discharge) was designed to ensure that site uptime was not compromised.
