A hybrid energy storage system (HESS) composed of electrochemical batteries and supercapacitors is considered. The supercapacitors aim to manage the peak power and thus increase the lifetime of the battery. A control scheme of this HESS is obtained by inversion of its energetic macroscopic representation. This control scheme enables different energy management strategies using a distribution input to share the energy between both devices. A switching strategy and a frequency strategy have been tested using this same control scheme. This flexible control scheme has been validated in real time by using a real HESS and a hardware‐in‐the‐loop simulation of the traction system of an electric vehicle.
