Abstract
Provided is a battery system capable of preventing the voltage that is applied to the voltage detection circuit from exceeding the withstand voltage of the voltage detection circuit when the connection between the cells in the battery module is disconnected, and preventing an overcurrent from flowing in the cell voltage detection circuit and the module. The modules are internally provided with a battery voltage measurement circuitfor measuring the voltage of each cell. A reverse voltage protective diodeis disposed in the power supply route of the battery voltage measurement circuit, and adapted such that the anode thereof is connected to the negative electrode of a drive power source of the voltage measurement circuit and the cathode thereof is connected to the positive electrode of the drive power source of the voltage measurement circuit. A fuseas an overcurrent protective element is provided to the power supply route of the battery voltage measurement circuit
