Abstract
A method of estimating the residual energy of a battery. The method comprises determining the battery's state of charge (SOC) and dischargeable capacity to determine the battery's state of energy (SOE), determining the battery's reference dischargeable energy (E) and total dischargeable energy (E), and comparing the state of energy to the total dischargeable energy to find the residual energy of the battery. The various functions of the method use battery current, cell temperature, and state of health (SOH) as variables for consideration.
