Abstract: A power source supervisory apparatus is provided with a connection path that connects between a first path and a second path, an inter-path switch SW provided on the connection path, a current limiting element disposed to be in series to the inter-path switch SW on the connection path enabling a conduction from a first path side to a second path side under a current limiting state and obstructing conduction from the second path side to the first path side, a supervisory unit that supervises occurrence of a voltage drop on the first path in a state where the inter-switch is closed, and a switch operation unit that opens the inter-path switch SW when the supervisory unit determines that a voltage drop occurs on the first path.

Abstract: A battery pack is provided which includes a battery, a circuit board equipped with load feed lines, bus bars connecting with the battery and the circuit board, first and second switches, and third to sixth switches. The first and second switches are disposed in a housing which is higher in capacity of heat dissipation than the circuit board. The third to sixth switches are disposed on the circuit board. The first and second switches are larger in amount of electrical current flowing therethrough than the third to sixth switches on time average. This enables the size of the battery pack to be reduced without sacrificing the dissipation of heat from the switches.

Abstract: A battery device includes a battery pack, a circuit substrate which acquires battery information on the battery pack or controls charge and discharge of the battery pack, a switch including a first power element or a second power element, and a heat radiator. The switch is a device controlling input and output of electric power to and from the battery pack, and an exterior part of the switch is arranged away from the circuit substrate. The heat radiator is a member made of a material having thermal conductivity, and is in direct contact with or indirect contact via a heat conductor with the exterior part of the switch so that heat of the switch can be transferred.
