摘要:
A power supply device includes functional modules, and a main controller that is connected to and controls the modules. Each module includes a battery block, a communication interface, a memory and a battery state detector. The block includes a battery cells that are connected in serial and/or in parallel to each other. The interface exchanges data with other modules or the controllers. The memory can store data exchanged through the interface. The battery state detector can detect at least one of current, voltage and temperature of the block. When the module is connected to the controller, the controller assigns a unique address to the module. The module stores the unique address, which is assigned by the controller, in the memory. The module exchanges data based on the address.

The battery system is provided with a battery 1 that can be recharged, a fuse 8 connected to the battery 1 that blows with excessive current flow, relays 2 connected to the output-side of the battery 1, and a current cut-off circuit 4 that detects excessive battery 1 current and controls the relays 2. The current cut-off circuit 4 detects excessive battery 1 current, and is provided with a timer section 24 that designates a time delay until the relays 2 are switched from ON to OFF. For the delay time of the timer section 24, the fusing current of the fuse 8 is set lower than the maximum cut-off current of the relays 2 and higher than the maximum allowable battery 1 charging and discharging current. In a situation where excessive current greater than the maximum cut-off current of the relays 2 flows through the battery 1, the fuse 8 is blown during the timer 24 delay time, and the current cut-off circuit 4 switches the relays 2 from ON to OFF when the delay time has elapsed.

A variable displacement compressor comprising a cylinder block having a plurality of cylinder bores. The cylinder block has an extension which extends from an outer periphery of an end surface of the cylinder block which faces a swash plate. The extension has an extension surface which forms a part of a bore surface of each cylinder bore and first and second wall surfaces which extend continuously from opposite ends of the extension surface in a circumferential direction of the extension surface. A part of each extension surface which is connected to the first wall surface which is located on a preceding side of rotation of the swash plate corresponds to a high-load area which is locally subjected to loads from a single-headed piston during a compression stroke. The high-load area has a chamfered region which is formed into a curved surface by chamfering.
