The invention discloses a charging method for a storage battery of a new energy vehicle, and belongs to the technical field of vehicle batteries. The method is applied to a vehicle control unit and comprises the steps that under the condition of an active awakening state, the charge state of a storage battery and the charge state of a power battery are obtained; under the condition that the charge state of the storage battery is smaller than a first charge threshold value, the current environment temperature is obtained; based on the current environment temperature, a charging threshold value corresponding to a temperature interval where the current environment temperature is located is determined, the environment temperature is divided into a plurality of temperature intervals, and different temperature intervals correspond to different charging threshold values; and controlling the power battery to charge the storage battery in response to the condition that the charge state of the power battery is greater than or equal to a charging threshold value corresponding to the temperature interval in which the current environment temperature is located. According to the method, the electric quantity of the power battery is taken into account under the condition of ensuring that the storage battery is charged, and the drivability of the vehicle is ensured.
