Frequently asked questions

What is SoC in a BESS?
The State of Charge (SoC) indicates what percentage of the theoretically available capacity of a battery is currently occupied.
How is the SoC technically captured?
The value is retrieved via the soc register and is based on current integration as well as voltage monitoring in the system.
Why is an accurate SoC important for profitability?
An accurate SoC allows for effective temporal planning for arbitrage operations and prevents costly deep discharges.
From when does the lifespan decrease with an incorrect SoC?
Continuous charging in the zone above 90% or discharging below 10% leads to chemical degradation of the cells.
How does the SoC influence system usage?
The SoC determines how much energy is available for regulation power or Peak Shaving, which directly influences revenue.
Which standard governs measurement in the BESS?
The IEC 62933 standard defines the requirements regarding performance and monitoring of battery storage systems.
