    Abstract: A vehicle body component mounting system is provided with, along a conveyance path for a vehicle body, an upstream component mounting work area using a cell production system, a central component mounting work area in which the vehicle body is conveyed by an overhead conveyor, and a downstream component mounting work area using the cell production system in this order. Components other than principal components are mounted to the vehicle body using the cell production system. The cell production system is adaptable by increasing the number of component boxes, and thus an increase in the length of the line is prevented. The increase in the length of the line is prevented by using a line production system as a base and also using the cell production system as a part thereof.

  • Publication number: 20130308239
    Abstract: A switching circuit (13) is provided with a charging switch (31) and a discharging switch (32). When the charging switch is turned ON, a battery module (21) is charged by electric power from an electric power supply (ACP, 16). When the discharging switch is turned ON, the power discharged from the battery module is outputted to a load (LD). If there is abnormal heat buildup or some other anomaly in the battery module, a main control unit (11) immediately turns off a breaker unit (14) provided between the switching circuit and the battery module. If the anomaly is noncritical, such as a communication anomaly, and does not immediately threaten the safety of the battery module, a grace period is set and the breaker unit is kept in the on-state until the grace period ends.
