BATTERY CAPACITY ESTIMATION METHOD, AND BATTERY MODULE AND ELECTRONIC PRODUCT USING THE SAME

A battery capacity estimation method, and a battery module and an electronic product using the same are disclosed. In the battery capacity estimation method, after a control system of the battery module has judged that a battery has been charged to a fully charged state for a predetermined period and entered a rest state, a detection unit of the control system measures an open circuit voltage and a temperature of the battery, according to which a full charge capacity of the battery is calculated.
