Abstract
A battery pack can include a battery and a battery management system for detecting a charge amount of the battery, setting an indicated charge amount as the charge amount if the charge amount of the battery is smaller than a first threshold value, and setting the indicated charge amount as that of the following equation 1 when the charge amount of the battery is greater than or equal to the first threshold value. Indicated charge amount=actual charge amount×correction rate=actual charge amount×(1+((100/second threshold value)−1)/(second threshold value−first threshold value)×(actual charge amount−first threshold value))), [Equation 1] wherein the actual charge amount is the charge amount of the battery.
Claims20
A battery pack comprising:
- a battery;
- and
- a battery management system that detects a charge amount of the battery, sets an indicated charge amount as the charge amount when the charge amount of the battery is lower than a first threshold value, and sets the indicated charge amount as given in Equation 1 when the charge amount of the battery is higher than the first threshold value:
- Indicated charge amount=Actual charge amount×correction rate=actual charge amount×(1+((100/second threshold value)−1)/(second threshold value−first threshold value)×(actual charge amount−first threshold value))) [Equation 1]
- wherein, in Equation 1, the actual charge amount is a charge amount of the battery, and
- wherein the indicated charge amount is for displaying on a display as a battery charge state.
An electronic device comprising:
- a display:
- and
- a controller that receives a charge amount of a battery in a battery pack built in the electronic device, sets an indicated charge amount as the charge amount when the charge amount of the battery is lower than a first threshold value, sets the indicated charge amount as given in Equation 1 when the charge amount of the battery is higher than the first threshold value, and displays a battery charge state in the display corresponding to the indicated charge amount:
- Indicated charge amount=actual charge amount×correction rate=actual charge amount×(1+((100/second threshold value)−1)/(second threshold value−first threshold value)×(actual charge amount−first threshold value))) [Equation 1]
- wherein, in Equation 1, the actual charge amount is a charge amount of the battery.
