成果简介	NOVELTY - The method involves calculating a first voltage and a first current associated with a battery (113) at each timestamp value in a range of timestamp values, and determining degradation voltage and an energy value corresponding to the battery based on the calculated voltage and the current for each timestamp value in the range of timestamp values. A reference curve is generated with respect to the timestamp values based on determined degradation voltage and the energy value. A second voltage and a second current associated with the battery are calculated at each timestamp. A second degradation voltage and a second energy value corresponding to the battery are calculated based on the calculated second voltage and the second current for each timestamp value. A state of health of the battery is determined based on the estimated deviation. USE - Method for estimating a state-of-health and remaining useful life of a battery i.e. rechargeable lithium-ion battery, in an electronic device (claimed). Uses include but are not limited to a personal computer, a table personal computer, personal digital assistant, a mobile device, a palmtop computer, a laptop computer, a desktop computer, a communications device and a wireless telephone. ADVANTAGE - The method enables reducing time for predicting battery health by avoiding dedicated testing of the battery in the electronic device to predict battery health in real- time for on-device battery during partial or full charging or discharging of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electronic device for determining a state of health of a battery. DESCRIPTION OF DRAWING(S) - The drawing shows a block diagram of an electronic device for determining a state of health of a battery. 100Electronic device 109Database 111Operating system 113Battery 115Display unit
