Abstract
A battery system includes a battery unit including a plurality of battery cells, a controller electrically connected to the battery unit, a power supply source supplying electric power to the controller, and a voltage detection means disposed between the controller and the power supply source and detecting a voltage value of the power supply source. The voltage detection means includes a first resistor connected in series to the power supply source, a second resistor connected in series to the first resistor, an A/D converter electrically connected between the first resistor and the second resistor so as to branch to the second resistor, and a diode electrically connected between the first resistor and the A/D converter so as to be inversely connected to the power supply source and to branch to the second resistor.
