摘要： The state of charge (SOC) estimation device includes a memory and a controller component. The memory stores data on a first correlation between an elapsed time and an estimation error in SOC estimation. The controller component executes a first estimation process and a second estimation process. The first estimation process is for estimating a first SOC and a first estimation error of the electric storage device in a non-charge/discharge state based on a terminal voltage and the elapsed time. The second estimation process is for estimating a second SOC and a second estimation error of the electric storage device in a charge/discharge state based on an accumulated charge/discharge current. The controller component calculates a total error from the first estimation error and the second estimation error. The controller component estimates the first estimation error when the elapsed time becomes equal to or longer than a reference time.
