Audi Bring Out Erot Unloose Energy Harvesting 'Regen' Daze Absorders

We accept reported on a broad hit of unloosen energy regenerative daze absorbers over the years that some oft convert linear motion into electricity. Audi is working on a image called “eROT,” inwards which electrical motors supersede telescopic daze absorbers inwards the cast of electromechanical rotary dampers.

The regulation behind eROT is easily explained: “Every pothole, every bump, every bend induces kinetic unloosen energy inwards the car. Today’s dampers absorb this energy, which is lost inwards the cast of heat,” said Dr.-Ing. Stefan Knirsch, Board Member for Technical Development at AUDI AG. “With the novel electromechanical damper arrangement inwards the 48-volt electrical system, nosotros pose this unloosen energy to use. It also presents us together with our customers amongst alone novel possibilities for adjusting the suspension.”

The eROT arrangement responds speedily together with amongst minimal inertia. As an actively controlled suspension, it adapts ideally to irregularities inwards the route surface together with the driver’s driving style. H5N1 damper feature that is virtually freely definable via software increases the functional scope. It eliminates the usual dependence of the rebound together with compression strokes that limits conventional hydraulic dampers. With eROT, Audi configures the compression stroke to move comfortably soft without compromising the taut damping of the rebound stroke. Another payoff of the novel damper arrangement is its geometry. The horizontally arranged electrical motors inwards the raise axle expanse supersede the upright telescopic daze absorbers, which allows for additional infinite inwards the luggage compartment.

The eROT arrangement enables a instant share equally good the freely programmable damper characteristic: It tin sack convert the kinetic unloosen energy during compression together with rebound into electricity. To create this, a lever arm absorbs the motion of the cycle carrier. The lever arm transmits this forcefulness via a serial of gears to an electrical motor, which converts it into electricity. The recuperation output is 100 to 150 watts on average during testing on High German roads – from 3 watts on a freshly paved spear to 613 watts on a oil secondary road. Under client driving conditions, this corresponds to a CO2 savings of upwards to 3 grams per kilometer (4.8 g/mi).

The novel eROT applied scientific discipline is based on a high-output 48-volt electrical system. As currently configured, its lithium-ion battery offers an unloosen energy capacity of 0.5 kilowatt hours together with peak output of xiii kilowatts. H5N1 DC converter connects the 48-volt electrical subsystem to the 12-volt principal electrical system, which includes a high-efficiency, enhanced output generator.

Initial exam results for the eROT applied scientific discipline are promising, thence its utilization inwards hereafter Audi production models is for certain plausible. H5N1 prerequisite for this is the 48-volt electrical system, which is a cardinal constituent of Audi’s electrification strategy. In the side past times side version planned for 2017, the 48-volt arrangement volition serve equally the principal electrical arrangement inwards a novel Audi model together with feed a high-performance mild hybrid drive. It volition offering potential fuel savings of upwards to 0.7 liters per 100 kilometers.
