A method for controlling charging of a secondary cell including a positive electrode containing a positive-electrode active substance having that increases resistance in accordance with an increase in the SOC, a negative electrode; and a non-aqueous electrolyte includes performing constant-current charging at a set current value to a prescribed upper-limit voltage, performing constant-voltage charging at the upper-limit voltage after the upper-limit voltage V1 has been reached, and terminating charging of the secondary cell when the charging current in the constant-voltage charging has decreased to a cutoff current value, the cutoff current value being set to a current value that complies with the relationships in formulas (I) and (II): Cutoff current value A2≧set current value A1×X  (I) X=(cell resistance R1 of secondary cell in target SOC [Ω]×set current value A1 [A])/upper-limit voltage V1 [V].  (II)
