  • Battery pack
    Patent number: 7964300
    Abstract: There is provided a risk-free and easy-to-use battery pack using battery cells 1 as a secondary battery, in which internal gases evaporated by applying overvoltage or the like thereto are processed inside a case to be prevented from leaking to the outside of the case and thereby even if the case has been led to rise in pressure due to a thermorunaway of the battery, the case is free from breaking. To realize this performance, the battery pack 10 is provided with a battery cell housing 17 for housing lithium cells 1 and a gas processor 15 for liquefying the internal gases g generated from the lithium cells 1.

  • Maintenance Bypass Device
    Publication number: 20100187908
    Abstract: There is provided a maintenance bypass device capable of achieving safety and efficiency in replacing work of a UPS. The maintenance bypass device (1) is equipped between a power supply (300) and a load device (400) and in parallel with an uninterruptible power supply unit (100), and supplies power from the power supply (300) to said load device (400) when the uninterruptible power supply unit (100) is being detached. In the maintenance bypass device (1), the connection portions (15, 16) of connecting wires (501, 502) connected to the uninterruptible power supply unit (100) are disposed on a front panel (2) disposed on the front side and are a connector type that enables the connection portions (15, 16) to be connected to and disconnected from the connection wires (501, 502) without using a tool.
