of 48 V on-board power supply battery
The open circuit voltage and the complex internal resistance between 1 Hz and 1 kHz must be determined on a 48 Volt on-board power supply battery, from which the status variables of ageing, charge condition and AC and DC internal resistance are to be mapped. Capacitive residual components can be determined without complicated discharge measurements in this way.
