摘要：A method and device for estimating remaining available energy of a powerbattery is provided. The method includes: estimating (S102), under current state,maximum available energy of a first cell with minimum State of Charge (SOC), and

maximum available energy of a second cell with minimum of maximum available capabilityin the power battery; estimating (S104) remaining available energy of the first cell basedon its maximum available energy and SOC, and estimating (S104) remaining availableenergy of the second cell based on its maximum available energy and SOC; andestimating (S106) the remaining available energy of the power battery based on thenumber of cells included in the power battery and the smaller one of the remainingavailable energy between the first cell and the second cell.
