Configuration watchdog – a special algorithm checks your basic settings in the background and only activates the system if they are plausible. This avoids, for example, that 5 modules can be configured even though the system only recognizes 4.
Possibility for different strategies to calculate SOC and SOH – decide for yourself how your GRNbms suits your project
