Somebody wake me up. This cannot be. It just cannot be. One of the reported problems with the BMW Mini-E is that apparently MOST of the vehicles have a problem with the transmission just magically kicking into NEUTRAL while going down the road – even while accelerating. A lot of the owners are returning the

Regenerative Braking

The AC induction motor and controller give us the option of employing “regenerative braking”. This concept derives from the fact that there really isn’t much difference between a motor and a generator. If you apply voltage to the motor, the shaft turns. On the other hand, if you turn the shaft, voltage comes out. The

We currently have an Intro video showing the features of the car and why we selected it for conversion. We also have our first conversion video which covers the wheels, brakes and suspension. This will give you a sample of the level of detail we intend, and just how boring these videos promise to be.

Thundersky Batteries

We’ve received a lot of questions about the Thundersky LiFePo4 batteries we used in the 1957 Speedster conversion. I’ve done an hour and a half video on the topic of battery chemistry where I stumble through an attempted explanation of how they work. And we bandsaw a Thundersky battery into pieces and take it apart

Porsche Speedster Achieves 100 miles on a single charge

We recently upgraded the 1957 Porsche Model 356 Speedster electric conversion by adding two additional Thundersky LiFePo4 90 Ah batteries in the rear engine compartment. We placed polyethylene grommets over the terminals of the existing exposed batteries in the rear engine compartment to act as standoffs. We found these on the counter at the local

New Blog

Welcome.   In the last year, batteries sufficient to drive a motor vehicle have become available to mere humanoids.  I’ve waited a number of years for this technology as I was never able to pencil an electric car that would satisfy my design parameters with lead acid batteries or the many variants that were available.
