You REALLY want to help newbies at this? Post up a correlation between electric motors and ICE setups. They are NOT the same HP or performance, but there MUST be a correlation to help people get an idea on what they need to select to get the performance they want.
I'm an ICE gearhead from way back, and I've been researching a conversion for years now but I had all but given up. I worked out the details for a supercharged 427/8 speed for my project, but decided to take one more stab at electric. The only way I've been able to get my head even halfway wrapped around a conversion correlation was when I stumbled across a Tesla S motor up for sale that listed its power specs. From there I was able to get a point baseline for performance so I finally have some sort of an idea on what I want. Example, a Tesla S has a 0-60 time of around 3 seconds and a quarter mile time in the 10-13 second range, weighs in around 4300lbs and uses (according to the site selling one) a 400KW motor. I know the numbers aren't completely accurate, just what I remember them being. At any rate, I finally felt confident about what I think I need in an EV motor that I finally moved into the next phase, asking manufacturers for information about specific motors.
People can read the HP and TQ for an ICE vehicle, and know what sort of performance to expect. If there was a way to read the HP and TQ for an EV and know what to expect, more people might be willing to pull the trigger. So, for those of you who blazed a trail, please, go a step further and make a Rosetta stone. You built it so you know what's in it. A chart that lists everyone's car and its drivetrain specs and an analysis of how it drives would be great. Something in a standardized format with defined parameters to compare one to another in an apples to apples style format would make this a lot easier. A visit to your local dyno shop for a couple of runs, followed by a trip to the drag strip for times would be an even bigger help. This sort of information would bridge the gap between ICE and EV for the mechanially minded, who are the only ones who would be attempting a conversion. Those who aren't mechanically inclined would be more likely to buy an OEM. I realize this is both asking for a lot of work on everyone's behalf while also asking for a lot of money to be spent, but it would help drive more conversions. I can even suggest a few fields:
- Car weight before conversion
- Car weight after conversion
- Car cd (available online)
- Drivetrain specs
- Power specs
- Range
- Power consumption at WOT
- Power consumption on level ground at 10-100MPH in 10MPH increments
- Power consumption when pulling a hill (steep, moderate, shallow) at city/highway speed
- Towing capacity
- 0-60, 1/8 mile, 1/4 time (1/4 mile tracks can provide all 3)
- HP/TQ rated on a dyno. The dyno will read your EV like it is an ICE, and will convert it into a graph an ICE minded person can understand.
- Any other data fields you think would be useful
This information can also give you a baseline record for your own use, or if you want to see how someone else's controller or battery works with your motor so it's not all one way here. Everyone can benefit.
