Classification: CPC H  Y | IPC H

Claim 0:
1. A smart battery device, comprising:
a battery unit;
a temperature-sensing unit, configured to sense an ambient temperature to generate a temperature signal; and
a processing unit, coupled to the battery unit and the temperature-sensing unit, wherein in a charging mode, the processing unit is configured to receive the temperature signal and obtain a power capacity of the battery unit, set a full capacity according to the temperature signal, and generate an indication flag when the power capacity of the battery unit reaches the full capacity, wherein the indication flag is used to indicate that the battery unit is in a fully charged state;
wherein the processing unit further determines whether a temperature of the temperature signal is lower than a first predetermined temperature;
when the temperature of the temperature signal is lower than the first predetermined temperature, the processing unit controls the smart battery device to enter a protection mode;
when the temperature of the temperature signal is not lower than the first predetermined temperature, the processing unit determines whether the temperature of the temperature signal is lower than a second predetermined temperature;
when the temperature of the temperature signal is lower than the second predetermined temperature, the processing unit sets the full capacity to a first predetermined value and generates the indication flag when the power capacity of the battery unit reaches the first predetermined value, and the indication flag is provided to a power receiving device, such that the power receiving device displays that the battery unit is in the fully charged state;
when the temperature of the temperature signal is not lower than the second predetermined temperature, the processing unit determines whether the temperature of the temperature signal is lower than a third predetermined temperature;
when the temperature of the temperature signal is lower than the third predetermined temperature, the processing unit sets the full capacity to a second predetermined value and generates the indication flag when the power capacity of the battery unit reaches the second predetermined value, and the indication flag is provided to the power receiving device, such that the power receiving device displays that the battery unit is in the fully charged state;
when the temperature of the temperature signal is not lower than the third predetermined temperature, the processing unit determines whether the temperature of the temperature signal is lower than a fourth predetermined temperature;
when the temperature of the temperature signal is lower than the fourth predetermined temperature, the processing unit sets the full capacity to a third predetermined value and generates the indication flag when the power capacity of the battery unit reaches the third predetermined value, and the indication flag is provided to the power receiving device, such that the power receiving device displays that the battery unit is in the fully charged state; and
when the temperature of the temperature signal is not lower than the fourth predetermined temperature, the processing unit controls the smart battery device to enter the protection mode;
wherein the second predetermined temperature is higher than the first predetermined temperature, the third predetermined temperature is higher than the second predetermined temperature, the fourth predetermined temperature is higher than the third predetermined temperature, the second predetermined value is lower than the first predetermined value, and the third predetermined value is lower than the second predetermined value.
