Method and configuration for monitoring a vehicle battery
First Claim
1. A method for monitoring a battery, the method which comprises:
- activating a power conservation mode of an electrical system of a motor vehicle, the power conservation mode being a transport mode for reducing consumption of electric power during transport or storage of the motor vehicle;
measuring a duration of activation of the power conservation mode of the electrical system;
repeatedly measuring a quiescent voltage of a vehicle battery of the motor vehicle when the power conservation mode of the electrical system of the motor vehicle is activated;
determining a battery status based on the duration of activation of the power conservation mode and based on the quiescent voltage of the vehicle battery; and
providing information indicative of the battery status such that the information is perceivable outside the motor vehicle when the power conservation mode of the electrical system of the motor vehicle is activated and an ignition lock of the motor vehicle has no vehicle key inserted therein.

Abstract
A method for monitoring a battery includes the steps of activating a power conservation mode of an electrical system of a motor vehicle, measuring a duration of activation of the power conservation mode of the electrical system, and measuring a quiescent voltage of a vehicle battery of the motor vehicle. A battery status is determined based on the duration of activation of the power conservation mode and based on the quiescent voltage of the vehicle battery. Information indicative of the battery status is provided such that the information is perceivable outside the motor vehicle. A flashing pattern of a light emitting diode may for example indicate the battery status. A motor vehicle having a battery monitoring configuration is also provided.

6. A motor vehicle configuration, comprising:
-
a motor vehicle having a vehicle electrical system including an ignition lock, a vehicle key, a control device, a vehicle battery, a voltage sensor and an indicator device; said control device being configured to selectively operate said vehicle electrical system in a power conservation mode and in a normal operating mode, the power conservation mode being a transport mode for reducing consumption of electric power during transport or storage of said motor vehicle; said control device including a timer and being configured to determine a power conservation mode activation duration when operating said vehicle electrical system in said power conservation mode; said voltage sensor being operatively connected to said vehicle battery and being configured to repeatedly measure a quiescent battery voltage when said vehicle electrical system operates in said power conservation mode; said control device determining a battery status as a function of the quiescent battery voltage and the power conservation mode activation duration; and said indicator device being operatively connected to said control device and being configured to provide information indicative of the battery status such that the information is perceivable from outside said motor vehicle when said vehicle electrical system operates in the power conservation mode and said vehicle key is not inserted in said ignition lock. - View Dependent Claims (7, 8, 9, 10, 11)
