Abstract
A method for operating a battery of a parked motor vehicle includes determining an operating state of the motor vehicle, determining a current charging state of the battery when the operating state of the motor vehicle is a parked state, determining a first upper charging state limit value of the battery, first active lowering of the charging state of the battery when the current charge state is greater than the first upper charging state limit value, determining a second upper charging state limit value of the battery, and ending the first active lowering of the charging state when the charge state of the battery falls below the second upper charging state limit value. The invention also relates to a motor vehicle.
Claims10
A method for operating a battery of a parked motor vehicle, comprising the following steps:
- determining an operating state of the motor vehicle using a control apparatus of the motor vehicle,
- determining a current charge state of the battery by means of the control apparatus when the operating state of the motor vehicle is a parked state,
- determining a first upper charge state limit value of the battery by means of the control apparatus of the motor vehicle,
- first active lowering of the charge state of the battery by means of the control apparatus of the motor vehicle when the current charge state is greater than the first upper charge state limit value,
- determining a second upper charge state limit value of the battery by means of the control apparatus, the second upper charge state limit value being less than or equal to the first upper charge state limit value, and
- ending the first active lowering of the charge state by means of the control apparatus when the charge state of the battery falls below the second upper charge state limit value.
