Power supply device and vehicle using the same

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.

1. A power supply device comprising:
a plurality of functional modules; and a main controller that is connected to and controls said plurality of functional modules, wherein each of said plurality of functional modules comprises
a battery block that includes a plurality of battery cells connected in serial and/or in parallel to each other,a communication interface that exchanges data with other of the functional modules or said main controllers,a memory portion that can store data that is exchanged through said communication interface, anda battery state detection portion that can detect at least one of current, voltage and temperature of said battery block, wherein when the functional module is connected to said main controller, the main controller assigns a unique address to the functional module, wherein said functional module stores the unique address, which is assigned by said main controller, in said memory portion, wherein said functional module exchanges data based on the address, wherein said memory portion is a nonvolatile memory, wherein said plurality of functional modules are connected to said main controller through said communication bus in the power supply device assembling process, wherein said main controller assigns the unique addresses to the functional modules through said communication bus in the order of the turning-on of the power to the functional modules, wherein said functional modules store their unique addresses in said nonvolatile memories when recognizing the unique addresses, and wherein said functional modules exchange data based on the unique addresses on next startup.
