Deep-discharge protection method and motor vehicle

摘要

A deep-discharge protection method for protecting a battery of a parking motor vehicle is shown. In this case, a state of charge of the battery is regularly monitored by a battery control unit and is transmitted to an evaluation unit. When a predefined state of charge of the battery is reached, a message is transmitted from a communication unit to a stored address by mobile radio and/or information acquired using a sensor system is used by the evaluation unit to determine whether a situation of the motor vehicle is suitable for autonomous recharging of the battery.

1. A deep-discharge protection method for protecting a battery of a parked motor vehicle, comprising:
regularly monitoring a state of charge of the battery with a battery control unit; transmitting the state of charge of the battery to an evaluation unit receiving with the evaluation unit sensor data corresponding to an environment around the motor vehicle from a sensor system associated with the motor vehicle; initiating, with the evaluation unit, recharging of the battery by a generator in response to the sensor data indicating that the vehicle is in an outdoor location; and when a predefined state of charge of the battery is reached, transmitting with a mobile radio a message from a communication unit to another electronic device that is not operatively connected to the battery with reference to a stored address of the other electronic device to inform a user of the electronic device of the state of charge of the battery.
