The embodiment of the present application provides an acquiring method and device of residual energy of a power battery. The acquiring method includes: acquiring an available capacity of a first type of cells and an available capacity of a second type of cells; determining a minimum available capacity of the available capacity of the first type of cells and the available capacity of the second type of cells as an available capacity of the power battery; determining available energy of the first type of cells in accordance with the available capacity of the power battery, a current temperature, and a quantity of cells of the first type of cells; determining available energy of the second type of cells in accordance with the available capacity of the power battery, a current temperature, and a quantity of cells of the second type of cells; and determining the sum of the available energy of the first type of cells and the available energy of the second type of cells as a quantity of residual energy of the power battery. The acquiring method is used for effectively and accurately acquiring the residual energy of a power battery with multiple types of cells.
