Air Force tests all plug-in vehicle fleet in California; part of large DoD V2G project

Green Car Congress

The 42-vehicle fleet marks a milestone in partnership between federal, state and private energy organizations, as well as in DoD’s demonstration of emerging vehicle-to-grid technology. The vehicles have the capability to direct power both to and from the electrical grid when they’re not being driven. Coritech DC (V2G using SAE Combo).

Maxwell supplying ultracaps to ABB for hybrid version of Philadelphia rail energy recuperation system

Green Car Congress

When decelerating or braking, a traction vehicle (train, tram or trolleybus) is feeding the regenerated braking energy back into the DC power network. Rather than having the braking energy be dissipated, the ENVILINE Energy Recuperation System (ERS) saves the surplus braking energy of the train by returning it back to the AC grid.

The Relay That Changed the Power Industry

Cars That Think

Advances in power electronics Power system faults can happen when a tree or vehicle hits a power line, a grid operator makes a mistake, or equipment fails. A protection scheme should quickly isolate the fault from the rest of the grid, thus limiting damage on the spot and preventing the fault from spreading to the rest of the system.

The Vacuum Tube’s Forgotten Rival

Cars That Think

An old-fashioned triode vacuum tube does that using a voltage applied to its grid electrode. Amplification occurs because a relatively small DC control current can modify a much larger AC load current. Researchers soon constructed what was called core memory from dense grids of magnetic cores. An amplifier, by. David Schneider.
