Abstract
A method for determining an equalizing charge of a battery in which the battery is overcharged beyond a nominal full state of charge includes detecting full charging operating phases in which the battery is at least in the nominal full state of charge and adding up charge quantities which are charged into the battery in the full charging operating phases to obtain a value of the equalizing charge.
Claims20
A method for determining an equalizing charge of a battery in which the battery is overcharged beyond a nominal full state of charge, the method comprising:
- detecting full charging operating phases in which the battery is at least in the nominal full state of charge;
- and
- adding up charge quantities which are charged into the battery in the full charging operating phases to obtain a value of the equalizing charge.
A monitoring device for batteries comprising:
- a device for identifying a current state of charge of a battery;
- a charge measuring unit for continuously measuring charge quantities that are charged into the battery;
- a monitoring unit configured to detect full charging operating phases in which the battery is at least in a nominal full state of charge and to add up the charge quantities that are charged into the battery in full charging operating phases, the monitoring unit further configured to determine an equalizing charge of the battery as a function of the added-up charge quantities.
