摘要:
A battery module and an overcharge protecting method are provided. The overcharge protecting method includes following steps: detecting a battery voltage of a rechargeable battery during a charging process; determining whether the battery voltage is larger than or equals to an upper limit voltage; if no, continuously charging the rechargeable battery until the battery voltage reaches a charging cut-off voltage and then the charging process is ended; if yes, stopping the charging process, reducing the value of the charging cut-off voltage and using the reduced charging cut-off voltage as the charging cut-off voltage in the next charging process. In the subsequent charging process, once the overcharge occurs, the value of the charging cut-off voltage is continuously reduced until the overcharge of the rechargeable battery does not occur during the charging process.

A power adaptor is provided. The power adaptor includes a voltage converter, a connecting port, a first transformer and a controller. The voltage converter receives an input voltage and determines whether to convert the input voltage to an output voltage according to an indicating signal. The first transformer includes a primary side and a secondary side. The primary side and the secondary side are coupled to each other, and a first end and a second end of the secondary side are coupled to the connecting port, respectively. The controller generates the indicating signal according to a voltage at the primary side of the first transformer. The connecting port is used to connect to an electrical device, and when the connecting port is electrically connected to the electrical device, a first end and a second end of the secondary side are short to a reference ground end of the secondary side.

The invention discloses a compute system which may detect the state of a power supply. The system includes a power supply and a motherboard. The power supply has a detecting unit for detecting a power state of the power supply. The detected information is converted to a high-frequency signal and outputted to the motherboard via a “power good” pin in an ATX power connector. The motherboard may obtain a voltage, current, power, temperature and other values inside the power supply via the ATX power connector and allow the values to be displayed on the screen to provide a real-time monitoring function for the users.
