Abstract
In one embodiment of the present invention, a system is provided or measuring the voltages of the traction batteries of an electric vehicle. The system includes switches provided to switchably couple the batteries individually to an amplifier. The system also includes switches provided to assure that the same polarity is always provided to the amplifier; a single-ended amplifier can thus be used. The system includes an analog-to-digital converter coupled in communication with the output of the amplifier, and an optical coupler which couples the output of the analog-to-digital converter to the low-voltage portion of the electric vehicle's electrical system.
