I'll be spinning this motor to a maximum of 4500 RPM. Typically AC motors spin to 10-15k RPM but mine is wound specifically for low speed which is what allows me to get away with direct drive into the differential.

Today is my last day in the states for the next two weeks, so there will be a lull on the progress front. In any case, I got some work done on the battery mount setup today. Some nut-serts and a coat of paint and the battery mount should be ready to go. When I return I'll be popping the batteries in, connecting up the high voltage wiring and inverter, and giving things a spin! I can hardly wait

 

Well guys, we're back in action and I've got another update to share. Today I plumbed up the high pressure side of the power steering pump and validated that the system is 100% operational now. Additionally, the pack has been physically mounted in the car and connected 2/3 (~250V) electrically. Next up we have to connect the rest of the battery wiring, install and test the motor inverter, and plumb the cooling system. At that point, we should be driving down the road.

Wow it's coming along great !!

 

Pretty amazing how quickly this is coming together!

More progress today! Taking a breather now that the jet lag is catching up to me. Today we got the battery wired up to a full 376 volts and fuse, although that came with a caveat. The DC/DC converter I'm using is only capable of taking 373v on the input side - somehow I missed that when a friend recommended this converter :/ oh well, maybe time to crack open the Nissan leaf parts I have stashed that do the same.

Also, I wired up the coolant pump and plumbed the hoses. Any tips on the best way to adapt the 1.5" and 1.75" radiator hoses to my 3/4" hose inlet and outlet? I'm struggling to find something simple and easy

 

Bryson, are you using a 3rd party host for pics? This project is really impressive btw...

 

Oh, yeah. Slick as can be.


1. Is 373 v close enough to 376 v's so as to be within a safe tolerance? Way beyond my electrical skill level.


2. Cooling! Interesting . The motor or the battery pack or both? Liquic via the Jaguar radiator?


3. My rough and ready approach to the reduction on the hoses would be a visit to the plumbing section of the local hardware store.


A somewhat more elegant approach would be to take the radiator to a shop to solder in the proper size "spigots".

Thank you much! I'm actually using the built in upload feature on this forum, in addition to lots of stuff on photo bucket (out of date, now that I think of it)

I've now found three different specs for this voltage converter: 370V, 373V (included in my paper manual), and 430V (from the site I ordered it!). I'm now wondering if I can simply modify the voltage protection circuit to allow the slightly higher voltage and see where that takes me...

As for cooling, both the motor and the inverter need cooling. A radiator about a third the size of the original would be fine, but I figure there's no harm in having extra cooling! And as you said, I swung by the local home depot and scrounged up some PVC tube to NPT adapters, then used some NPT to hose barb adapters that I already had around. Problem solved!


And today I hit a major milestone - I was super nervous for this - I spun the wheels with my home designed and built inverter! The [absolute] encoder signal coming out of the motor isn't compatible with the chip I'm using to process the signal, so I've gone ahead and ordered another [incremental] encoder which should hopefully solve the problem and get this show on the road!

Wednesday, both the encoder and the waterproof inverter enclosure should arrive, and at that point it's install, test and DRIVE IT!

Yeehaw

 

Today we wired the garage with 240V on a 50A circuit so that I can charge at a full 10kW! Also included in this is the beginning of the gas tank to charge port adaptation

 

Looks like I forgot to post the update of the charger install last night. Well here ya go I guess today is a double update!

 

My jealousy over the speed of your project is palpable!

cant wait to see it finished!

 

I have a set of S1 fuel caps that I would donate to your project for just the postage to you! They were taken off when I changed to S3 caps and tanks.

My ZIP is 91741

 

PM coming your way Roger! Thank you!!

 

Bryson

They are the way to you, due there Tuesday by USPS

Roger

 

thanks again!

 

No lower caps as they were needed for my car..

 

No problem, I'll be making new lowers

 

Wow, just wow!
May be time to get into the marker for electric conversions to classic cars with all the restrictions that are sure to come along.

 

But what about leaky head gaskets, and leaky oil cooler hoses? Leaky front and rear main seals? Wait! What about the cruddy fuel tanks that clog up all the fuel injection parts and stop you from making it home when you least expect it? I don't get it, what are you gonna do?
And now what do you call it? Seimenauar? I'm worried...

 

I just don't know what I'll do!!
