6 Frequently Asked Questions about “New energy battery saturation standard value”
Why do operational values limit the SoC range of a battery?
The height of battery current and battery power is decisive for the SOC value to which a battery can be charged or discharged. Therefore operational values limit the SOC range in which a certain constant current or power can be applied on the battery.
How much does a new battery energy storage system cost?
The cost of building a new battery energy storage system has fallen by 30% in the last two years. In 2022, a new two-hour system would have cost upwards of £800k/MW to build.
