This is a miata rear? so I'm assuming the person building is using speaker wire to power the motors?

 

I just hear sting in the background saying: "I want my COVID vaccine"

 

 

Yes, it's a Miata subframe. No, it's not speaker wire.

 

 

It seems that, most of the time when I see an EV-converted street Miata, it's some variant of this:




Or this:





Or this:





Or this:





Or this:






It is only very, very rarely, that I see anything resembling this:





And that distresses me.

I just hope that the last example is just a mockup and a proper battery enclosure will be added at some point. I have been present in LiPo fires in e-cars; not fun.

 

It's not, and they're LiFePO4 cells. The sort you can drive a nail through.

The guy has documented the build process of the battery packs, and he did wind up destroying a few of the cells in various ways. None caught fire.

That said, I wouldn't endorse going *quite* that DIY / cheap. Pre-made packs are available which enclose the cells in a rigid plastic case. These are more commonly what you see stacked in large arrays in EVs.

 

Been watching this series of electrifying a NB.

Technology has certainly improved. If they can get the weight down to what the car had with its ICE and provide a range of 200 miles I can see this being a viable consideration. If U.S. gas prices reach what they are in Europe, I would think demand for EV conversion kits would go nuts. My other car is a plug-in hybrid with 30 miles of EV range. My job is 12 miles away so my RT is all electric if I wish. Charging this car at night with a 110v outlet costs me less than 38 cents.

 

Is that the video series where the guy has 3d-scanned the inner bits of the car to design the layout of the system? If so, quite impressive work.

I'm in a nearly ideal position for EV ownership. My daily commute is about 6-7 miles round trip, most of it at 15-20 MPH. On rare occasion, I have to drive downtown, which is a whopping 6 miles each way.

So range isn't an issue. 30 miles would be more than adequate. Ironically, it's hard to find pre-made LiFePO4 cells which have a low enough Ah rating that I could assemble a pack which is physically small while still providing adequate voltage.

My biggest challenges are lack of free time and, like most city-folk, lack of build space and charging capacity at home.

 

Yes they do make a 3d scan of the engine bay, trunk space, and for the transmission to help with mating it with an electric motor. Space would be my challenge as well.

I thought these cells & this build were pretty attractive

 

Apparently this was in AZ today?

 

There was confirmation of a tornado near Kingman earlier today.
