The primary purpose of this paper is to investigate energy regeneration and conversion technologies based on mechanical–electric–hydraulic hybrid energy storage
The energy storage principle of this system is that during the boom lowering process, the gravitational potential energy is converted into hydraulic energy via the hydraulic cylinder and
The ex-isting energy storage systems use various technologies, including hydro-electricity, batteries, supercapacitors, thermal storage, energy storage flywheels,[2] and others.
There are two ways to reduce the energy consumption of the manipulator driving system. One way is to improve the driving system efficiency through reducing the valve throttle loss. The other is to recover and reutilize the lost gravitational potential energy.
The gravitational potential energy recovery and reutilization efficiency is greatly improved. The results show that the effect of energy saving is remarkable. Multi-joint heavy-duty manipulators, such as working devices of hydraulic excavators, are mostly driven by hydraulic cylinders.
However, due to the low power density ratio, the EMA is difficult to drive the heavy-duty manipulator independently. For the energy recovery mode, the hydraulic mode has less energy conversion links than the electrical mode.
To get the maximum benefit of the high power density of hydraulic and pneumatic energy storage, Bravo R R S et al. explored a new configuration of hydraulic–pneumatic recovery configuration for heavy vehicles to store braking energy used for propulsion or auxiliary systems, as illustrated in Figure 14. Figure 14.
The recovery efficiency of the gravitational potential energy is about 50%. Shen [ 28, 29] studied the characteristics of the hydraulic excavator driven by a hydraulic transformer. The method can avoid throttling losses in principle and recover the kinetic and the potential energy of the whole machine.
An EMA and a hydraulic cylinder-hydraulic accumulator combination are used to drive the manipulator together. Furthermore, electrically active and hydraulically passive driving systems are employed based on the operational characteristics of the heavy-duty manipulator.
