Battery charging system for a motor vehicle and method for charging a battery installed in a motor vehicle

摘要

The invention relates to a battery charging system for a motor vehicle, comprising a battery sensor for determining a state of charge of a battery of the motor vehicle, a transmitting and receiving device for transmitting and receiving signals by radio, and a coupled to the battery sensor and the transmitting and receiving device control device, which is formed such that when the battery sensor detects a low state of charge of the battery, the control means causes the transmitting and receiving device to send a request signal to a communication terminal of a user to ask the user whether an engine of the motor vehicle may be started, and when the transmitting and receiving device receives an allow signal from the communication terminal of the user, which allows the engine to be started, the control means generates a control signal for starting the engine.
