The Kit That Turns Gas Guzzlers into Plug-In Hybrids

Sitting in a Connecticut warehouse, the very first Poulsen Hybrid looks like a standard Honda Civic with immobilizer boots attached to its rear wheels. It is, one would have to say, not the most visually elegant of solutions to the pressing problem of using electric power to extend the range of the internal-combustion automobile. But it's also both practical and affordable.

The concept is relatively simple: Two of the company's seven-horsepower (five kilowatt) disc-shaped DC electric motors are bolted onto the rear wheels of the host car, connected by cables to a controller, battery charger and 4.5-kilowatt-hour lithium-ion battery pack in the trunk. The system, adding approximately 200 pounds to the car and taking up 20 percent of trunk space, acts as range extender. The motors do not drive the car, but kick in to provide a power boost between 15 and 60 miles per hour. Regenerative braking helps keep the batteries charged.
