Analysis

• Measurement of the open-circuit voltage for 48-volt on-board batteries
• Measurement of the complex internal resistance between 1 Hz and 1 kHz
• Evaluation of the state variables aging, state of charge as well as AC and DC internal resistance
• Connection via USB to DigiControl PC software with powerful process data logging

Task

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.
