Thoughts on a plug-in hybrid conversion
Hello!
I am the founder of a Seattle-based startup. We are developing a family of universal retrofit kits that convert existing vehicles into plug-in hybrids. Our first product will be for pickup trucks, and I am hoping to get some thoughts from this and other RV communities on what features may be desirable, what the major concerns would be, etc. My thinking is that for people who use their trucks for daily driving but also frequent towing, our product could be very attractive, especially because it can be used as a generator.
In a nutshell, the kits add an electric propulsion system good for 30-45 miles of range without removing the engine. The battery pack and power electronics get mounted in the bed like a small bed toolbox. We remove a section of the tubular part of the driveshaft and install a “coaxial drive unit” that has an electric motor stack, a planetary transmission, and a multi-mode clutch that can shift-on-the-fly. The clutch allows EV operation while disconnecting the engine/tranny, engine operation while disconnecting the electric motors, and generator mode which uses the engine to spin the electric motors without turning the wheels. A linkage that connects to the axle tubes provides reaction torque. We’ve prototyped a simplified version of the system and tested in on real roads.
Because the systems are universal, we can mass-produce them, have them installed by third-parties, and hit a much lower price point than other conversions (approximately $7k-10K covering the range from midsize to ¾ ton). I’d love to get the group’s thoughts and gage the level of interest.
