Video: Tesla Roadsters Quick Charge For The First Time Thanks to JdeMO Aftermarket Add-on

As any electric car owner will tell you, the ability to quick charge your car from empty to full using a high-power DC quick charging station makes your car far more practical than a car that needs four or more hours to recharge to full.

From the humble Nissan LEAF and its 50 kilowatt CHAdeMO quick charge port through to the proprietary 100+ kilowatt Supercharger technology built into every Tesla Model S and Tesla Model X, once you’ve owned an electric car with quick charging technology, you won’t want to buy one without it. It’s no surprise then that those who have cars without quick charging capabilities have long yearned for a way to add DC quick charging to their electric cars.

Rapid charging could be coming to a Tesla Roadster near you very soon.

The first vehicle which never included DC quick charging as standard from the factory to gain the capability was the 2012-2014 Toyota RAV4 EV, courtesy of Tony Williams of Quick Charge Power. Having carefully studied both the CHAdeMO protocol and the Tesla-engineered battery pack, drivetrain and power circuitry of the compliance car, Williams engineered, designed and tested a special aftermarket product called JdeMO which, when fitted to a customer’s car, safely allows 2012-2014 Toyota RAV4 EVs to rapid charge from the same CHAdeMO DC quick charging stations as the Nissan LEAF, Mitsubishi i-Miev and Kia Soul EV.

Our regular contributor Steven Noctor has one fitted to his own Toyota RAV4 EV, and reports that the unit has dramatically improved the practicality of operating the all-electric SUV as his family’s main car. With other customers all over the U.S., Quick Charge Power has received a lot of requests from owners of other non-DC quick charging cars, eager to have a similar product for their vehicle.

The upgrade should work for bother Tesla Roadster 1.5 and 2.5 models.

The upgrade should work for all Tesla Roadster 1.5 and 2.x models.

The next car to gain compatibility for this valuable aftermarket add-on? The original Tesla Roadster. And thanks to a YouTube video uploaded this evening, we can share footage of not one but two Tesla Roadsters rapid charging from a public CHAdeMO station for the first time.

The video shows the newly-developed JdeMO for Tesla Roadster fitted to both a Tesla Roadster 1.5 and Tesla Roadster 2.5 model. While the Tesla Roadster 2.5 has enough space next to its physically smaller Power Inverter Module (PIM) to accommodate the JdeMO inlet in the under-trunk area, the video shows a ‘temporary’ JdeMO inlet installed below the rear bumper on the Tesla Roadster 1.5 for testing purposes.

Once Quick Charge Power has completed its testing phase of the development process, we’re guessing it will develop a more appropriate (and permanent) CHadeMO inlet mounting arrangement for Roadster 1.5 owners.

Which brings us to a very important point. While both cars in the video were able to successfully charge first time, the JdeMO product for Tesla Roadster owners is still undergoing its final testing and isn’t (yet) a commercial product. Unlike the JdeMO for 2012-2014 Toyota RAV4 EV — which you can order today for $2,999 via the Quick Charge Power webiste — Quick Charge Power isn’t officially accepting orders for the JdeMO for Tesla Roadster.

The Tesla JdeMO is based on the JdeMO product designed for the second-generation Toyota RAV4 EV.

Instead, there’s a link on the website where interested owners can sign up for addition information — and raise their hand as being interested ahead of official production. As with any commercial product, the company says it needs significant interest from existing Roadster owners before it makes a final decision about production. Given the improvement in charge times JdeMO will offer over the original Roadster (which could at best charge in 2.5 hours from empty to full using a specially-designed 19-kilowatt Tesla high power wall connector), we suspect Roadster owners will be lining up to put deposits down.

In the meantime, we’ll keep track of this exciting new product, and let you know as and when it makes it to production.

    I’m on the list, deposit paid!

  • Very interesting. Good to see older EV’s being able to join the quick charge party.

    WHat this also tells me is that innovators like Tony Williams have moved their creative focus from the Nissan LEAF to Tesla products. The LEAF has been great in that there are third party ad-ons that improve the owner experience. If the mindshare is shifting to Tesla products guess where my dollars will go next.

      Coworker’s 2012 Leaf SL is now over three years old, has almost 30,000 miles (mostly commuting, weekend errands), has lost one capacity bar, however the car is in perfect shape, clean interior, quiet suspension, handles like new, no problems other than flat tires and a defective infotainment unit that was replaced when he got the car. He managed to extend his lease for another year and plans on buying the car at the end. It’s costing him peanuts and he loves the car. Has only DC fast charged it once, rarely charges in public, and I am still trying to get him to stretch his “electric legs” and go on trips beyond the range of the car.

      Nissan claims the 30 kWh batteries would not be available for retrofit on these cars, but I really doubt Nissan will make a stockpile of the 24 kWh batteries for eventual replacements. And if not Nissan someone else like Tony will find a way to retrofit new higher capacity cells into the old packs.

      I love Tesla, that’s where my dollars went next too, but they can’t do it on their own, and are not the answer for everyone.

    I’m excited and I don’t even own a Tesla! My friend Sam does though and this up’s the argument for more DCQC in our state and along interstate highways which fossil fuel companies and their political representatives fear like vampires fear crosses.

    I can’t wait to tell Sam about this! So cool!
