  • DIY Open-Source Plug-in Hybrid Pickup Truck

    No. This is one of those projects that sort of fell between my skill-sets, my budget, and what was affordable and appropriate technology.I still love the idea of the project, but at this point, a used Chevy Volt would be about the same price as what it would cost for the batteries, charger, motor controller, etc. for a DIY project.I really believe that a commercially built plug-in hybrid pickup truck has a HUGE market potential.A Ford F-150 Energi would be a fantastic vehicle.In the mean time, electric vehicles have really been taking off. Even my Mitsubishi iMiEV works great pulling a trailer. So it's a very useful vehicle, but range becomes SO limiting when pulling that extra weight. A plug-in hybrid truck would be great for so many people.I even pitched the details of my plug-in hybr...

Some of the smartest people in transportation in the world were there, and they all liked my design.I'm sure we'll be seeing plug in pickups pretty soon. In the mean time, I have other projects I'm working on, and not the time and budget for the truck.

    Build Your Own Electric Car!

    When the car is turned on, the airbag light flashes a certain number of times. It's a "self-test" and indicates that the airbags are working properly. The controls for the air-bags are a separate car computer from all the other car functions. In the Metro, it's mounted near the bottom of the central console. I did NOT modify the airbags, the daytime running lights, or the seatbelts in any way, so as to keep all the original safety equipment in stock and working condition.

    Been there, done that, wrote the Instructable on it. https://www.instructables.com/id/DIY-Plug-In-Hybrid-Car/ It worked fine, but the main drawbacks were how much cargo space got used up, and the noise from the generator. Generator exhaust was routed through the bottom of the cargo area and through a riding lawn mower muffler!

    I have a friend who built two frames for XR3s. Those are a neat concept and the finished one looks really cool. Building the frame is the hardest part for a hobbyist. My friend had lots of experience with metal, welding, and fabricating, so he built those two frames to sell to other guys who were interested in building XR3s but didn't have the skill and experience for the frame part of it.I still like the idea of doing a diesel/electric plug-in hybrid pickup truck. It would be a similar concept, only using a stock vehicle like a Ford Ranger or Chevy S10.

    My latest project is a solar garage. It provides all the power I need for my entire house and an electric car. Electric Cars and Solar Power go GREAT together! You can see a few photos at: http://300mpg.org/2017/06/26/game-of-drones/

    Build Your Own Electric Car!

    Mother Earth News built a Hybrid with a system similar to what you describe. They had plans available for purchase. A friend gave me an old copy of the plans. Pretty neat stuff!http://www.motherearthnews.com/green-transportation/electric-car-conversion-zmaz79jazraw

    Right now (July 2017) is a GREAT TIME to buy a used electric car. When I originally built this car, there weren't any available. An electric car conversion still makes a lot of sense for a classic car or an unusual car which you wouldn't otherwise have available as an electric. If you just want nice clean transportation for everyday travel, a used Nissan Leaf, Chevy Volt, or similar vehicle makes a good choice.

    You also have to remember that a car needs a differential to split the power from the gas engine or electric motor to the two drive wheels. In most front-wheel-drive cars, the transmission and differential are one combined unit. I would typically just drive in 3rd gear (for my single-speed gear reduction) and the two "half-shafts" from the transmission connect the power to the two front wheels.There are pickup truck conversions which use a large electric motor more or less directly on the differential on the rear of the truck. In a pickup, the transmission is separate from the differential, and it is POSSIBLE to skip the transmission entirely, but still best to have gear reduction.

    The motor that I used didn't have an identification plate on it, so I had no way of reading the actual specs on it. It was originally designed for 36 or 48 volts. I ran the motor in the car mostly at 72V, but also experimented with running it at all the way up to 144V DC.On a series-wound DC motor, speed is proportional to voltage, so a higher system voltage will mean a higher top speed.I've gotten a speeding ticket in this car.

    Hello!I just tested them, and the links worked fine on my computer. Maybe it's just some difference between the web browser on my computer vs. yours. I haven't head any comments from anyone else about the links not working. It's even possible that the particular web page in question was down briefly while you were trying to go to it.Thank you for bringing this to my attention. If the links still don't work for you, please just use a Google search to try to bring them up.Thanks,-Ben Nelson

    It's not really that one or the other - series or parallel - connections are more efficient than each other. In series connections, voltage increases. In parallel connections, current or capacity increases. However, with DC motors, speed is proportional to voltage. Therefore, connecting your batteries in series is the preferred way to go. You get a higher voltage, thus higher top speed from your motor. Also, higher voltage means lower current draw for the same amount of power. Lower current means that you can use thinner cabling, which is less expensive, easier to work with, and saves weight.

    The designs vary a bit. Some of the earlier ones are pretty simple - good to keep a little kid busy for a few minutes. The designs that are more detailed are great for adults. Those are better when you have some quiet time to yourself, and DO take a while!
