You certainly want a manual transmission.

Typically, you won’t be shifting at all, so an automatic transmission is a complete waste of energy that will ultimately cost you perhaps 10% of your battery capacity.

People would charge their cars mostly during the night. That’s when the demand for electricity is lowest. Only difference it would make is there would be no more “off peak” hours for electricity.
The consumption would be more balanced than today. I think it would be actually a good thing for the power companies. They would need to adjust production much less.

What type of transmission is best to use? Manual or Automatic. Manual would probably be easier as the automatic needs a way to know when to shift..usually by vacuum from the engine. Im sure there is more modern automatic trans that could be used.

What I really love about the electric car revolution is that the technology is available to enthusiasts to DIY. It really harks back to the early days of motoring where loads ot enthusiasts built up their own cars. What really turned me onto the possibilities was when I read an article about electric drag cars, built by the enthusiasts themselves. As battery and motor technology improves things can only get better!

In the meantime I am thoroughly enjoying your blog, and have you bookmarked as a favorite. Keep up the good work!

Without the keyway, your biggest challenge is the coupling slipping under high torque. You can weld it, but you have to make sure the weld is strong and there are no cracks.

You can also check out the other motion control couplings from Lovejoy.

Will, how does the Lovejoy coupler work on the splined shaft of a transmission since it does not have a keyway?

Can you tell me what the part number is for the Lovejoy coupler.
thanks

[...] connecting the electric motor to the existing transmission unit, most EV retrofitters will use the Lovejoy metal coupler. Putting the coupler on the motor shaft is easy. But how do you put the coupler on the transmission [...]

Hi Tim,

The Lovejoy unit is only a coupler that connects the shaft of the electric motor to the core of the transmission unit.

The system that can generate power when the EV slows down is call the regenerative system. I wrote a short article about it. Check it out below.
