[variation 2 of embodiment 1]
From charging station 30 when electrical storage device B charges, with different in the travelling of vehicle 10, can set desirable charge condition (charge rate).Here, the voltage Vb of electrical storage device B is accompanied by the charging of electrical storage device B and rises, but when the deterioration of electrical storage device B was carried out, because the increase of internal resistance, ohmic loss also increased, so the escalating rate of voltage Vb descends.In addition, ohmic loss and charging current square proportional is so the decline of the escalating rate of the big more then voltage of charge rate Vb is remarkable more.Therefore, can be based on the deterioration state of estimating electrical storage device B from the escalating rate of the voltage Vb of charging station 30 when electrical storage device B charges.
