Abstract
Method and apparatus for accurately measuring charge storage system operating conditions in a vehicle. A measurement circuit produces an electrical response at an output which varies linearly with voltage levels measured via a remote connection to the battery terminals. The circuit is calibrated to provide that electrical levels are produced at the output only over a voltage range above a specified voltage level at the battery terminals in order to improve the resolution in detecting these levels using a standard electrical level detector such an ammeter or voltmeter. The measurement circuit is connected to a display circuit for indicating at least one charge storage system operating condition based on the terminal voltage of the battery. Alternatively, the measurement circuit may be connected to a display circuit for indicating the specific gravity of the battery based on the terminal voltage of the battery.
