The invention discloses a vehicle storage battery health degree assessment method, a storage medium, electronic equipment and a vehicle. The method comprises the following steps: acquiring power-on state data of a vehicle in past preset time, and acquiring a voltage value of a storage battery in past preset time; health degree evaluation index data of the storage battery are obtained according to the power-on state data and the voltage value, and the health degree evaluation index data comprise at least one of discharge depth index data, over-discharge condition index data, over-discharge deviation condition index data and dynamic load voltage index data; and according to the health degree evaluation index data, obtaining a health degree comprehensive score of the storage battery. According to the method, a series of health degree evaluation index data influencing the performance of the storage battery are obtained by obtaining the power-on state data of the vehicle in the past preset time and the voltage value of the storage battery in the past preset time, and the health degree comprehensive score of the storage battery is obtained based on the health degree evaluation index data.
