PURPOSE: A battery system for a micro-hybrid vehicle containing high power load devices is provided to efficiently supply electricity to the high power load devices by connecting high voltage electric system, low voltage electric systems, and starter circuits using coupling units. CONSTITUTION: A battery system for a micro-hybrid vehicle containing high power load devices includes one or more starter circuits, high voltage electric systems, and low voltage electric systems. A starter circuit includes a first battery(10) and a starter(11). The starter is connected or connectable to the first battery and starts an internal combustion engine on the basis of starting signals. A low voltage electric system includes a second battery(15) and one or more electrical load devices(14-2). The second battery generates a first voltage to be output to the low voltage electric system. A high voltage electric system includes a third battery(20) and an electric generator(13-2). The third battery generates a second voltage, which is higher than the first voltage, to be output to the high voltage electric system. The electric generator operates by the internal combustion engine and generates a third voltage, which is higher than the second voltage, to be output to the high voltage electric system. |
