description A method for determining the state of health of a power battery of an electric vehicle, and a server. The method comprises: acquiring battery data of a power battery and a vehicle feature of an electric vehicle (S21); according to a real-time battery-associated parameter, and a normal attenuation model corresponding to the vehicle feature, calculating a normal state-of-health attenuation value of the power battery (S22); according to a real-time fault type parameter and a fault attenuation model which corresponds to the vehicle feature, calculating a faulty state-of-health attenuation value of the power battery (S23); and according to the normal state-of-health attenuation value and the faulty state-of-health attenuation value, determining a comprehensive health evaluation value of the power battery (S24). When the state of health of a power battery is assessed, the state of health of the power battery can be quickly assessed without the need to control the power battery to perform charging and discharging, a
