ICE Breaker - converting a 1967 split to electric drive

That's going to be one seriously badass bus! Will there be a bolt on path to convert any Early ('71) Baywindow bus?

Was wondering how you'd deal with battery cooling. Interesting to see how it all fits.

Always thought there'd be loads of space underfloor in a bus for batteries but with the various tubes and things going through...

I've a belly-pan bus (double-door) which may or may not make something like this easier. Probably harder, were I to keep the belly pans since they slope up towards the sides of the vehicle and might restrict battery module height. But would provide protection. Figured I'd cut access hatches in the floor, so batteries are accessible from above.

Thanks for sharing, very interesting.

We put the motor back in the bus today and checked clearances ready for the driveshaft fabrication

yeah, i think jehu is going to make the switch to Tesla modules as well. I bet there will be a video on his youtube channel. He spends a lot of time at EV west these days

I spent some time reviewing the weight of the Bus conversion today;

The original bus weighed 1036kg (2285lbs).

Removing the ICE, Gearbox, Fuel Tank, and replacing the front/rear suspension with Red 9 resulted in the bus weighing 852kg (1878lbs).

Installing the Tesla Drive Unit, 4 Tesla Battery Modules and rear battery rack resulted in the bus weighing 1046kg (2306lbs).

Now for another 8 Tesla Battery Modules (200kg / 440lbs), 2 Battery Boxes (TBD), and a bunch of electronics (TBD).

While heavy, it looks as if my 1500kg (3300lbs) kerb weight target is achievable (same as a Nissan Leaf), while leaving 570kg (1250lbs) for payload

Carefully removing a redundant tab on the Tesla drive unit allows a bolt on IRS and ~350HP motor upgrade without cutting the bus

I'll try and record a video next week

We've been playing with radiator ideas... here's a 380mm x 280mm x 60mm mockup in the 'cooling cabinet' that we're creating on each side of the bus... we'll use these to get the bus moving and then revisit once we know more about airflow and cooling requirements

[Kevin Sharpe]

The Tesla drive unit mounting system has been extended to include the rear torsion tube

[nlorntson]

What does this gain?

[mandraks]

sturdier perhaps? we are going from a 50 horse to a 350 horse motor.

My open source inverter controller turned up today... not long until we start spinning the wheels
