At the recent Electric Vehicles Symposium, Wattshock exhibited their regenerative suspension retrofit shock. This component generates electricity from previously wasted kinetic energy in vehicles.
Wattshock works by exploiting the vehicle's weight by capturing down force through hydraulic pressure to power an alternator. This allows Off Road vehicles to utilize the energy of long travel suspension, or heavy duty suspension, to produce electricity.
The shocks are independent alternators and can replace the engine driven alternator on heavy vehicles. They can increase miles per gallon, decrease emissions, run high load electronic accessories, produce hydrogen by electrolysis and extend battery range. The Wattshock, will help buses, waste collection trucks, fleets and mining equipment increase fuel efficiency by exploiting the weight of the vehicle to generate electricity.
The Wattshock offers an even greater advantage when combined with regenerative braking and the regenerative suspension works whenever the vehicle is moving, not just upon braking. According to Wattshocks, a Toyota Prius could produce 1-2 kW/hr and a Ford F-150 could produce 2-4 kW/hr using Wattshocks. The company claims greater power output than Levant Power Corporation's GenShock because Wattshock uses an hydraulic motor and not a turbine. Wattshock claims to have earlier paptents but it does not use some of the electricity generated for active control of the electric shock absorbers to give a better ride, a Levant speciality.
