摘要：A method and device for estimating remaining available energy of a powerbattery is provided. The method includes: estimating, under current state, maximum

available energy of a first cell with minimum State of Charge (SOC), and maximumavailable energy of a second cell with minimum of maximum available capability in thepower battery; estimating remaining available energy of the first cell based on itsmaximum available energy and SOC, and estimating remaining available energy of thesecond cell based on its maximum available energy and SOC; and estimating the

remaining available energy of the power battery based on the number of cells included inthe power battery and the smaller one of the remaining available energy between thefirst and the second cell.
