A Build-It-Yourself Electric Vehicle

Taco Cowboy writes "Here's yet another exciting project for DIY geeks. Modi-Corp, a Japanese company, has just unveiled a new electric car that you can actually build yourself. Not to be confused with the Toyota 'Prius,' the DIY electric car from Modi-Corp is called 'PIUS.' It's a single-seat electric car that will be released next spring in Japan. The company hopes that the PIUS kits can be used as educational tools, expecting to sell them to universities and mechanical schools with the opportunity to have customizable parts embedded in the EV for testing."

    Seriously? They didn't think to run that past a single english speaker? Or South Park fan?

      I'm pretty shocked that you're shocked you were modded flamebait. You certainly couldn't have expected an Informative mod. Offtopic might have been a fit. Maybe you could have gotten a Funny, but it just wasn't that funny.

      I'm all for bashing Slashvertisment, but it's hard to call this that when it's a) Japan only, b) not yet released or priced, and c) of little commercial interest in the rest of the world.

      Irrelevant, yes. Slashvertisment, not this time.

      I've established from reading the Katakana text that it has a double-wishbone suspension with rigid axles, and disk brakes. It also has a 1500mm wheelbase; a 0.6 kW electric motor; and a 36 Volts, 38 Ah battery. Its tyre size is 3.00-10; the "FR tread" is 1130mm, and the "RR tread" is 920mm. It also seats 1 person, and weighs 200kg.

      I couldn't understand much more of the Kanji-heavy text.

  3. Ariel Atom? by aaronb1138 · · Score: 3, Insightful

    Specs are 15 mile range and 21 MPH top speed. So we're not talking about a kit car, but a low end electric go kart. Seriously, the environment would be much better served if you went with an Ariel Atom since you're going to be killing the efficiency of everyone behind you or the inevitable towing when it only goes 13 miles on a charge after 6 months. I assure you, you will be much cooler and have a lot more fun to boot.

      I was amazed it's performance is that poor.

      I've been designing a home-build EV myself and in some respects it's similar: a 4-wheeled, single-seat space-framed vehicle with a lightweight non-structural aero body wrapping around it. But there the similarity ends. Mine weights 200kg, has a top speed of 130 km/hr, will do 0-100km/hr in 4 seconds, runs at its top speed for 1 hour which gives it a range of 130km at worst, much more if driven sensibly and legally. I only need 15kW motor power and 15kW/hr of LiFePo batteries. Then again it's primarily intended as a fun track car, not a commuter.

      I just don't think they're trying very hard. And it's ugly too - they need a western stylist to fix that.

      It's car-think, period. A 600 watt motor is an absurd amount of power. A streamlined tricycle (Sinner Mango, something like that) happily cruises at 25mph under human power. Me-on-a-cargo-bicycle exceeds both top speed and range of this joke

  5. Hardly Exciting by DoctorTuba · · Score: 2

    This is no more a DIY EV than Lego Mindstorms is autonomous robotics. It's a one size fits all kit and the fit at 15 miles and 21 mph is pretty lousy. It might be a fun toy if priced at under $500, but where's the educational value? I'd guess it uses rudimentary components (simple DC motor, rheostat, lead-acid batteries). You could get the same education building an electric RC car, plane, or boat.

    So much THIS.

    Mid 60's cars are the best electrical systems to work on. Though, I do tend to prefer to throw on the one wire HEI distributor and single wire internally regulated alternator from later years for even greater ease. Not to mention, inside all three or so wire connectors you have for lights, what do we have, regular, industry standard size spade terminals. Just so easy.

    One of the top issues in the used car market isn't that cars aren't lasting mechanically. Many are mechanically good for 15+ years with minimal maintenance. Most issues I am running into are burned out electrical parts and bad wires. This is especially frustrating because the bad wiring issues are due to poor insulation quality, yet stuff 40 years old are still soft, pliable and without cracks. Same issue since the automotive industry jumped on lead-free solder. It's less the complexity and more the construction quality that has made ECU's a huge cash cow in the 5-8 year old car market. And here is another hint: a hall effect or other inductive pickup (Cam / Crank sensors) which is internally solid state by nature, should be UNBREAKABLE. If a solid hunk of plastic with x number of turns of insulated copper magnet wire wound around a soft ferrite core burns out, somebody either designed or built something WRONG.

    I don't think so. Those are good tires, and the brakes are large. The weight is low-ish and centralized.

    How would I know this? I ride a cargo bike, similar tires, similar (smaller) disk brakes, sometimes larger loads, sometimes come down hills at nice speeds (usually limit it to 35mph). Handling is fine; can go no-hands across 3 bumps in succession, or no-hands with a hundred-pound load.

    And with tires and shocks like those on an earlier cargo bike, I once hit an unexpected pothole (poor planning on my part) at over 30mph, and the net effect was a loud "bang!" as I bottomed the shocks, and sharp smack in the hands from the impact coming up the handlebars. The bike rode rock-solid straight through it all.
