  • Patent number: 9257728
    Abstract: A battery pack has battery cells and bus bars. Each of the battery cells is covered with an exterior case. All the battery cells are electrically connected in series through the bus bars. The battery cells are divided into a first stacked group and a second stacked group arranged adjacent to each other in a lateral direction of the battery pack. The battery cells in each stacked group are stacked in a thickness direction of the battery pack. The stacked groups have a different number of the battery cells in order to make a stair structure. An electrode terminal of one end terminal of the battery cells connected in series is arranged adjacent to the stair structure. A control board is arranged on a lower step part of the stair structure. Devices formed on the control board detect a state of each battery cell.

  • Patent number: 8849534
    Abstract: A vehicle control system is provided which is designed to stop or restart an engine automatically. The system is equipped with a vehicle speed determining circuit which determines the speed of the vehicle and has a dead zone around where a real speed of the vehicle is zero. The vehicle speed determining circuit has a characteristic in which when falling in the dead zone, the determined speed shows zero. When the determined speed is zero, and the real speed is expected to have dropped to zero, the system applies a first braking force to the wheel to keep the vehicle stopped. When the determined speed has become zero following the automatic stop of the engine, the system applies a second braking force smaller in magnitude than the first braking force to the wheel, thereby decelerating the vehicle slowly to avoid unexpected sudden deceleration.
