Abstract
To provide a battery system that can detect connecting locations of a plurality of battery packs with a simple structure, the battery system includes a plurality of terminal blockstoto which the plurality of battery packstoare connected. Each battery pack includes a first battery power supply terminal, a second battery power supply terminal, and a battery ID terminal. A power supply voltage is applied between the first and second battery power supply terminals, and the battery ID terminaldivides the power supply voltage into a first voltage to be applied between the first battery power supply terminaland the battery ID terminal, and a second voltage to be applied between the second battery power supply terminaland the battery ID terminal, when the battery pack is connected to the terminal block. A voltage dividing ratio of the first voltage or the second voltage with respect to the power supply voltage is made to be different among the plurality of battery packs depending on the terminal blocks, and the control circuitdetects the voltage dividing ratio and determines the terminal blocks to which the battery packs are connected.
