Description

technical field [0001] The invention belongs to the technical field of potential energy recovery and reuse, and in particular relates to a potential energy recovery and reuse energy storage device test system and method. Background technique [0002] Port cranes are the main loading and unloading equipment in specialized container terminal yards, and the gravitational potential energy in the process of lowering the cargo is converted into thermal energy of resistance. The potential energy recovery and reuse energy storage device manufactured by supercapacitor technology absorbs and stores the energy when the crane is lowered, decelerated and braked through supercapacitors, and then releases energy for use by the drive motor during lifting, which plays a role in absorbing and feeding back energy and The function of balancing the load when the system requires high power. [0003] The potential energy recovery and reuse energy storage device is a device that uses supercapacito...
