Abstract
The invention relates to an energy supply circuit of electric components, in particular for a motor vehicle, having an accumulator, wherein a discharge monitoring circuit monitors the energy stored in the accumulator. If the energy stored in the accumulator falls below a threshold value, the discharge monitoring circuit switches off the energy supply at least of individual components, in particular of all components.
Claims15
An energy supply circuit comprising:
- a rechargeable battery;
- and
- a discharge monitoring circuit,
- the rechargeable battery configured to supply electricity to electronic components in a motor vehicle,
- the discharge monitoring circuit configured to monitor a level of stored energy stored in the rechargeable battery,
- and to switch off energy supply to all said electronic components upon said level of stored energy falling below a threshold energy value,
- the discharge monitoring circuit also configured to switch back on energy supply from the rechargeable battery to a locking system component of a locking system of the motor vehicle.
