A Review of Electromagnetic Energy Regenerative Suspension

The energy regenerative process of the existing air-type and hydraulic-type active suspensions is relatively complicated: the vibration energy needs to be converted into internal energy, and then converted into electrical energy using a motor [7, 8].Both of them need to add subsidiary institutions, which increases the difficulty of control and lowers the energy conversion

Potential of different forms of gravity energy storage

Energy storage [7] represents a primary method for mitigating the intermittent impact of renewable energy. By dispatching stored energy to meet demand, a balance between supply and demand can be achieved.
