The invention provides a storage battery charging control method and an electric vehicle. The control method comprises the steps that the electric quantity, collected by a storage battery sensing module, of a storage battery is acquired; when the electric quantity of the storage battery is smaller than the cut-off discharge electric quantity, the direct-current converter is controlled to charge the storage battery according to the initial voltage threshold value; in the charging process, the storage battery charging current and the storage battery temperature collected by the storage battery sensing module are obtained in real time; determining a first selected voltage threshold according to the storage battery charging current and a first preset rule, and controlling the direct current converter to charge the storage battery according to the first selected voltage threshold; or, determining a second selected voltage threshold according to the temperature of the storage battery and a second preset rule, and controlling the direct-current converter to charge the storage battery according to the second selected voltage threshold. According to the control method, when the electric quantity of the storage battery is smaller than the cut-off discharge electric quantity, the electric quantity can be supplemented in time, and the charging voltage can be dynamically adjusted to charge the storage battery according to the charging current or the temperature of the storage battery in the electric quantity supplementing process.
