Starting battery`s operating condition monitoring device for passenger car, has electronic circuit adapted for power line communication, and electronic receiver with optical and/or acoustic display to receive and to display radio signals

摘要

The device has sensors to determine voltage and temperature of a starting battery (2) to provide the variables as electrical signals. An electronic circuit is adapted for power line communication, with which the signals are transmitted over an existing vehicle wiring (6) for a cigarette lighter box (7) in a passenger compartment (9) of the vehicle. Another electronic circuit (8) converts the signals into radio signal and transmits the radio signals. An electronic receiver (10) e.g. mobile telephone, with an optical and/or acoustic display receives and displays the radio signals.
