Automotive parts developers ZF and Levant Power are developing a regenerative electric suspension system for hybrid cars that could give even more power to hybrid vehicles. 

“We look forward to working closely together with Levant Power. The objective is to develop the world’s first fully active and regenerative suspension, make it ready for volume production and introduce it to the market. Thus, we are promoting efficient innovations that are tailored to meet global requirements,” said Rolf Heinz Ruger, the head of suspension technology at ZF.

The system works with by installing a valve, control unit, electric motor and electrohydraulic gear pump to the damper. The valve uses the oscillation of the damper to drive the electric pump and convert the motion to electricity, which will be routed to the hybrid system. The pump allows the damper to adapt to driving conditions by increasing or decreasing the pressure on the fluid in the damper. 

ZF and Levant have not said how much power the system could scavenge from the movement of the suspension.

The concept allows for more of the car's usually wasted energy to be converted to electricity. The system would likely be used in tandem with a regenerative braking system.
