I'm trying to size up the conversion of a bus.

I don't yet have said bus but it's likely to be a double decker or single decker if it has to be. Think Leyland Olympian (bus) or Setra s328 (coach).

Average MPG of these jobbies (diesel) is 8MPG

HP for these busses seems to range from 300-500hp and torque around 700nm - 1500nm

Let's say that when it's loaded up I would expect total mass of between 10 and 15 tonnes

Now for my use I would be looking to achieve a range of around 60 miles between charges, used on mostly flat roads but with the capability to make it's way up a mountain once in a while (who wouldn't want to take their bus skiing!)

50mph would be more than sufficient.

So, where would you begin with finding a motor and batteries to carry out such a project?

We're working on another project that needs a big torquey motor. We have a motor for it that would probably be just right for your bus project. It does 1530 Nm peak and 770 Nm continuous with a peak power speed of 2700 RPM and a maximum speed of 6000 RPM.

But we don't have an inverter solution yet. We're hoping to have something to pair with it later this year, but can't make any promises yet. It's not trivial to come up with a 700VDC/900Arms inverter.

But I'll try to come back and ping this thread when we are ready to release, if you haven't found another option.
