The invention provides a primary frequency modulation capacity calculation method and device for an electric vehicle. The method comprises the steps that a first constraint condition and a second constraint condition are determined according to a target vehicle, and a third constraint condition is determined according to a target charging pile; calculating the maximum value of the discharging electric quantity and the charging electric quantity of the vehicle-mounted battery in the first target time period under the first constraint condition to obtain a first target lower bound and a first target upper bound; obtaining a second target lower bound according to the maximum value of the discharge capacity of the vehicle-mounted battery under a second constraint condition; obtaining a second target upper bound and a third target lower bound through maximum values of output and input of the target charging pile under a third constraint condition; and determining a minimum value of the first target upper bound and the second target upper bound as an interval upper bound, and determining a maximum value of the first target lower bound, the second target lower bound and the third target lower bound as an interval lower bound to obtain the frequency modulation capacity. The method solves the problem that a primary frequency modulation method in the prior art does not consider battery safety, user travel requirements and charging pile limitation.
