Learn how to optimize your energy storage with accurate state of charge estimation
Proper state estimation of batteries is of the utmost importance in all cases where batteries are used. You can only operate your battery energy storage system (BESS) to its full potential while keeping it safe if you know accurately in which condition your storage system is in. State of Charge (SoC) is one of the most important state estimations for batteries. It describes how much charge is left in your battery, which can be used, for example, to provide grid services like frequency regulation or arbitrage.
An inaccurate SoC can cause safety issues and economic losses due to non-reliable storage operation. Not being able to deliver the energy that had been promised to the grid can lead to high fines or even permanent exclusion from grid service markets. Major challenges exist when it comes to calculating State of Charge, often leading to inaccurate SoC readings.
