Abstract: A system for estimating the state of health (SOH) of a battery of an electric vehicle includes a charger recognition unit, a discharge instruction unit, and an SOH estimator. The charge recognition unit generates a charge recognition signal based on a charge state of the battery. The discharge instruction unit receives the charge recognition signal when the battery reaches at least one predetermined charge voltage value, temporarily stops charging of the battery, and discharges the battery to a certain level. Discharge is performed by operating at least one function of the electric vehicle. The SOH estimator estimates the SOH of the battery based on a voltage change measured during discharging of the battery based on the at least one predetermined current value.
