Abstract

An apparatus of delivering the power status data signal of the smart battery includes a control device, a data buffer device and a data storage device. The control device is for outputting a smart battery clock signal, a first clock signal and a second clock signal according to an input clock signal, and for receiving and outputting the power status data signal serially. The data buffer device is for receiving the power status data signal serially and outputting the power status data signal in parallel according to the first clock signal. The data storage device is for storing the power status data signal and outputting the power status data signal in parallel according to the second clock signal.

Claims

1. An apparatus for delivering a power status data signal of a smart battery, the apparatus comprising:

a control device for controlling the smart battery so as to output the power status data signal according to a smart battery clock signal, receiving and outputting the power status data signal of the smart battery serially, wherein the control device outputs a first clock signal a second clock signal and the smart battery clock signal according to a clock signal;

a data buffer device for receiving the power status data signal serially and outputting the power status data signal in parallel in response to the first clock signal; and

a data storage device for receiving the power status data signal in parallel and outputting the power status data signal in parallel in response to the second clock signal.

2. The apparatus according to claim 1, wherein the power status data signal is outputted from the data storage device to a basic input/output system (BIOS).

3. The apparatus according to claim 1, wherein the smart battery clock signal is outputted from the power status data signal delivering apparatus to the smart battery through a first bus, and the power status data signal is outputted from the smart battery to the power status data signal delivering apparatus through the first bus.

4. The apparatus according to claim 3, wherein the first bus is a system management bus (SM bus).

5. The apparatus according to claim 1, wherein the power status data signal is outputted from the power status data signal delivering apparatus to the basic input/output system through a second bus.
