Crown Bus Electric Conversion

Good Evening,

I need help with some basic advice. I am planning to buy a Crown Bus and I want to install Tesla motors and Batteries. Does anyone in this Forum did that before?

What are the pros and cons to take in consideration?

Thanks

Gonna have to subscribe to this one. I can only imagine a bus with unlimited off the line torque. Won't be a good cross country bus, but I like the possibilities

Tessa car motors will not be strong enough, you need to look at whatever motor they are using in the electric trucks and buses on the market now

779 horse power should even move a bus

Electric motor Front and rear motor combined output up to 779 bhp (581 kW), 920 lb⋅ft (1,250 N⋅m), 3-phase AC induction motor

The motors and batteries should be the easy part, but for me the electronics would be a major learning curve. What kind of range are you hoping for?

I have thought of just using one motor and putting it on the driveshaft for braking( and regen), and for a boost on grades, otherwise the bus engine would do it normal thing. Kind of a hybrid thing.

Are you an engineer and fabricator? Also wealthy? If so this may be your swap.

You did not state wether you want to add Tesla motors and batteries or replace the engine with a totally electric drivetrain?

That's what I think they're talking about.

I am assuming he must have real skills, or at least someone to help who does, I hope. yea money helps to. Have no idea what Tesla batteries go for let alone the motors. For me a dream idea.

My bus did much better pulling a trailer in the mountains then I expected, so pleased about that. But if lots of money falls out of the sky.... the hybrid idea is there....

Could be, since Iron Man's Arc Reactor is make believe,

Maybe the OP is hoping somebody has miniaturized Wardenclyffe Tower, AKA the Tesla Tower, and is willing to share...002b.jpeg
Now if I can only find someone to double check my ciphering for a dog nose cold fusion reactor, I'd be most appreciative...

Yes they do, but they can not maintain that power level without overheating, if you read tests of tesla's at tracks, they tend to overheat and shutdown. It takes about 12 HP to keep a car moving at 60 MPH, for a bus it is more like 60 HP for that speed, meaning the motor needs 6 times the cooling, which the tesla motors don't have the capability to do. There are companies making electric trucks and buses, those are the motors you need

I also posted about bus motors able to run 1100 miles per charge

While very interesting, those are purpose built from the ground up. Its not something thats gona be retrofitted and even if it were it would be astronomical in terms of price and complexity. Just buy one already built.

50 years from now when internal combustion engines are a thing of the past, there will be tons of surplus bus batteries and motors to pick from in salvage yards across the country.
But today is not 50 years in the future so all of the engineering, research, trial fitments are only just beginning for commercial sized vehicles.

Right now, unless you are Soros rich, converting an existing bus to full on electric is pie in the sky, but we'll all be watching you to see how far you chase your dream.
GOOD LUCK!!!, seriously...

I think it said it wasn't in production yet - I thought it was interesting that that sort of range was even possible - it's what we are going to see on the roads in the not too distant future - a related item came up in my search that claimed electric cars will soon be cheaper to buy than gas fired cars in the near future - I don't doubt it

Says they've already delivered at least 100 units.
