    摘要： A safety valve 13 is integrally formed in a battery lid 3 together with a peripheral wall portion 14 by press and the like. The safety valve 13 is formed in contact with the peripheral wall portion 14, at the bottom portion of the depressed portion 18 depressed from the upper surface 12a of the base portion 12 of the battery lid 3. The upper surface 13a of the safety valve 13 is located below the lower surface of the base portion 12. When pressing force X parallel to the upper surface 13a of the battery lid 3 is exerted on the inner peripheral surface 14a of the peripheral wall portion 14 while the connection tube and the like is connected, the pressing force X can be supported by the entire thickness (plate thickness) T of the base portion 12.

    摘要： A battery control circuit includes a voltage detection circuit (124) for measuring voltages of electric cells (111), balancing circuits for balancing the voltages or SOCs of the electric cells (111), a signal input/output circuit (129) for communicating with the outside, a power supply circuit (126) having two modes: a normal mode and a low consumption mode, and a time management circuit (127). It receives a signal containing a period of time until the shift of the power supply circuit (126) from the normal mode to the low consumption mode, and stores it in the time management circuit (127). If a command from the outside has not been sent for a predetermined period of time or when an operation stop command has been sent from the outside, the time management circuit (127) causes the power supply circuit (126) to continuously operate in the normal mode. Then, the battery control circuit monitors an operation continuation period in the normal mode, and causes the power supply circuit (126) to shift to the low consumption mode when the operation continuation period matches the stored period of time.
