Patent FR-2583583-A1 (FR)
Inventor: STEFFENS WILLI
IPC: G01R31/36
Filed: 1985-12-27
Abstract: In order to monitor continuously the state of charge of a battery, the relaxation voltage of the battery is measured directly, or predicted from measurements taken with no current or only a small current flowing through the battery. From the relaxation voltage, the notional state of charge of the battery, prior to switching on of significant loads or of a charging device, is calculated. During later operation, with the loads and/or charging device in use, the current drawn from or fed to the battery is constantly measured and integrated and the state of charge is continuously estimated from the result of the integration and the notional state measured with the battery previously at rest.
