Registering an Electric Conversion in Maryland

One of the sticking points people have when deciding whether to do a conversion is worrying about if they’ll even be able to tag it upon completion. Will an electric vehicle conversion pass state inspection?

If you just bought your conversion candidate, the quick way around this issue is to get the car inspected before it’s converted.  Once it’s street legal in the state you can carry out your conversion without getting it re-inspected upon completion.  When you receive your emission test notice in the mail, simply check the box on the back that indicates your car is electric drive.

Of course, with the MR2 everything was done the hard way.  An inoperable car was bought out of state and then converted, meaning it had to pass inspection as an electric vehicle.  The process actually went well with only a few bumps.  The first garage I took it to declined to do the inspection.  Maybe I should have given them warning that I was bringing in a conversion, but I did put in a call to the MD State Police Automotive Safety Enforcement Division (ASED) to confirm that the only special consideration in inspecting an EV conversion was to cross through the inapplicable areas on the inspection form, like those pertaining to emission equipment and the exhaust system.  Feeling a bit more hopeful, I got on the phone and after explaining the situation and giving them the number to the appropriate officer at ADEP, I found another station that was willing to do the job.

I spent a few hours the afternoon of the inspection talking with Scott the mechanic as he performed the inspection.  He was very curious about all the aspects of the MR2 as he enjoyed modifying cars himself but never considered turning one into an EV.  Unfortunately, the rotors were underthickness but after spending a Sunday afternoon doing a brake job, the inspection certificate was finally awarded.

So at least in Maryland, red tape isn’t a disincentive to performing your own electric vehicle conversion.

Resurrection through Conversion

A few people have asked my why did I bother using a nearly 20 year old car as the basis for a relatively expensive conversion.  A good question with several answers.

Even if tomorrow every new car for sale was electric, there would still be about 100 million gas cars out there with years of useful life left in them.  It wouldn’t make much sense to trash perfectly good machinery, even if it is gas powered.

That’s where the beauty of a conversion shines through.  A good, rust-free body is kept in service but cleaned up with a battery electric drivetrain, saving the pollution and expense that comes with building an all-new electric car.

Applied to the MR2, with its fatal rod knock and age this car would likely have been sent to the crusher or rusted away unused in a field without the new lease on life the electric powertrain gave it.  It would have been a shame if one more example of one of the all-time great sports cars for the commoner were destroyed, a fate that has befallen many a Fiat X1/9, Mazda RX-7, or any British car.

Putting an electric powertrain in an old sports car is a great way to enjoy their simplicity and fun without the maintenance difficulties and pollution that old gassers inevitably produce.

That’s the big picture.  The other factors in the MR2’s favor are the fact that it’s already a small and efficient vehicle so it would make the most of the batteries, I’ve liked this model for years and tis particular example came up for sale at just the right time, price and condition.

EVision Installation, cont.

The EVision is now up and running, beeping and flashing as it keeps track of amps and voltages. Here’s the display on the dash:EVision in DashOut of the box, the display is configured to mount upright. The MR2 dash doesn’t have a large enough ledge for the base to fit so I turned the internals upside down inside the housing so that the base could be screwed to the underside of the hood. It looks good there, blocking out the non-functional tachometer, though the display does wash out in direct sunlight as the binnacle doesn’t shade the EVision display as well as the other instruments. Maybe in the future I’ll better integrate it into the main cluster, dropping some of the non-functional gages as well.The HMI (Human-Machine Interface) takes the place of the gear shifter in the center console:Console ControlsThe EVision HMI is similar to the iDrive system in BMWs in that the knob responds to rotation by cycling through menus designed in the software program and selects items by pushing down on the knob.  The white LED is surprisingly bright at night, if the black plastic switchboard was changed to a clear plastic it might be enough to illuminate the other switchgear.  The other controls are the drive selector switch in the middle, full/low power toggle on the left and regen on/off on the right.
