Abstract
A battery life alarm system and a battery life alarm method are provided. The battery life alarm system includes a first arithmetic unit, a second arithmetic unit and a third arithmetic unit. The first arithmetic unit outputs a capacity ratio according to a sense voltage and a design capacity of a battery. The second arithmetic unit outputs a life ratio according to a used life parameter and a design life parameter of the battery, wherein the used life parameter and design life parameter correspond to the using time or the charge/discharge times of the battery. The third arithmetic unit outputs a life index according to the capacity ratio, the life ratio and a weighted percentage.
Claims20
A battery life alarm system, comprising:
- a first arithmetic unit used for outputting a capacity ratio according to a design capacity of a battery and a sense voltage;
- a second arithmetic unit used for outputting a life ratio according to a used life parameter and a design life parameter of the battery, wherein the used life parameter and the design life parameter correspond to the using time or the charge/discharge times of the battery;
- and
- a third arithmetic unit used for outputting a life index according to the capacity ratio, the life ratio and a weighted percentage.
A battery life alarm method, comprising:
- (a) outputting a capacity ratio according to a design capacity of a battery and a sense voltage;
- (b) outputting a life ratio according to a used life parameter and a design life parameter of the battery, wherein the used life parameter and the design life parameter correspond to the using time or the charge/discharge times of the battery;
- and
- (c) outputting a life index according to the capacity ratio, the life ratio and a weighted percentage.
