Abstract

A vehicle electricity storage system includes a control device including: a calculation unit configured to calculate an internal resistance value of the battery based on the voltage value and the current value; a derivation unit configured to derive an estimated internal resistance value, which is an estimated value of the current internal resistance of the battery, based on the calculated internal resistance value calculated and the current voltage value; and a setting unit configured to set a charging electricity upper limit value, which is an upper limit value of charging electricity for charging the battery, based on the derived estimated internal resistance value, the current voltage value, and a current value at present. The derivation unit is configured to derive a greater value as the estimated internal resistance value, as a difference between an upper limit voltage value of the battery and the current voltage value becomes smaller.
