Abstract

The invention provides a composite energy storage system, a control method thereof and mobile equipment. Specifically, the composite energy storage system comprises an integrated controller and an energy storage structure, the integrated controller comprises: an information measurement unit, which is used for detecting a designated position of the energy storage structure to obtain a voltage valueand a current value of the designated position; a mode selection unit, which is used for calculating the power demand of the energy storage structure according to the voltage value and the current value, and determining the working mode of the energy storage structure according to the power demand; wherein the working mode comprise a pre-charging mode, a driving mode, a first power supply mode, asecond power supply mode, a first energy recovery mode and a second energy recovery mode; and a mode output control unit, which is used for controlling the energy storage structure to work accordingto the working mode, so that the integrated controller improves the energy efficiency of the composite energy storage system by adjusting the working mode of the energy storage structure, and a relatively good practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of composite energy storage, in particular to a composite energy storage system, a control method thereof, and a mobile device. Background technique [0002] Energy storage systems are widely used in mobile and electrified systems, such as electric vehicles, mobile robots and mobile communication devices, and are playing an increasingly important role. Long battery life requires the energy storage system to have a large energy density, while fast charging and fast energy output require the energy storage system to have a large power density. However, current energy storage systems, especially battery energy storage systems, are difficult to simultaneously address the demands of high energy density and high power density. [0003] Existing methods mainly realize the requirements of large energy density and high power density through a composite energy storage system, wherein the composite energy storage syst...
