The invention discloses a pressure control method and device for an energy accumulator. The method comprises the steps of: determining the working temperature and working condition of a hydraulic system, and adjusting the working pressure range of an energy accumulator according to the working temperature and working condition of the hydraulic system. In the working process of the hydraulic system, the working pressure range of the energy accumulator is adjusted according to the working temperature and the working condition of the hydraulic system, and different working pressure ranges are set for the energy accumulator according to the actual working condition and the working temperature of the hydraulic system, so that the working pressure range of the energy accumulator conforms to the actual working condition of the hydraulic system; and the problem that loss of the hydraulic system is large due to the fact that the working pressure range of the energy accumulator is constant is solved, oil loss of the hy
