EVDrive 27/2013 eGrizzly Status Report

EVDrive 26/2013 The EVTV Battery Pack

Cable Harness

I am building myself a new cable harness for my need.

It starts pretty tough but then it becomes more easy...

The best part is, if everything is connected and works perfect.)

Water Cooling

Water cooling is working.

Radiator And Pump

Radiator and pump are installed.

Radiator Mounting

But then it came all different with the fan...

New Electric

Today I visited Anne from New Electric again.

We had a great lunch.

 I picked up 80 CALB CA60AH cells for the ATV.

Detail And Finish

EVDrive 25/2013 back to the future

The Back Box

With the back box I can change the polarity of the field coils in a series wound motor.

I can spin the motor CCW and CW.

EVDrive 24/2013 Rotation Change

EVDrive 23/2013 eGrizzly First Ride

Weekend Shift

A job in a nature reserve came in.

She is not really ready, but ready enough for a test job.

The special feature: driving on the beach and "in" the sea.

Finding Mr Right Place

In addition to my normal work, I have spent this week to find the perfect place for the DC-DC converter. It has to be dry, heat conductive, airy, secure, be easily accessible and Deep wading.

Not so easy on an ATV.

Work Is Worth

It seems slower than it is.

The small details are very time-consuming.

But the work is worth it.

Mounting Adapters

To build the mounting adapters takes forever this week.

One rear mount

A front Mount

Three points are enough for now.

The Perfect Spot

The best Controller position is found (I Guess).

I think I have checked all possible mounting positions...

Controller Fitting

I bought a Soliton Junior from rebbl.nl for this project.

I would say: excellent choice.

EVDrive ATV Drive Test 22/2013

EVDrive 21/2013 Direct Drive Test

This is a direct drive test with the max. set up at the Soliton1 at 120 volts and 500 amps.

Take Off

Guess What..

Direct Drive Mounting

The WarP 9 or better the brush holder is not really made for running clockwise.

So my main drive is coming from the CE head.

STOP

I already had the old broken motor on the hook to bring it back in the ATV to fix it. But suddenly I said to myself: "Stop this..."

I never finished the test.

My thought was that the battery pack will be too heavy. But then an another idea came to my mind...

But first testing!

Aestivation

This project fell to sleep a little. I am getting more things together on my 2CV test bench car and next on the Toyota Landcruiser.
But the Grizzly will be an awakening.

EVDrive 02b/2012 test charge with the Brusa NLG513

EVDrive 02a/2012 test charge with the Brusa NLG513

Could not wait..)

I did a very raw test drive with a 12v Battery. I was happy like a little boy...))

I measured 10V and 120-130A at about 10Km/h.

Starting at about 280A and a very close circle at about 180A dropping to 9,5V.

Motor fitting

Motor timing and cable change from CCW to CW

Mockup clearance test

Frame work to bring in the WarP9

Heating up the adapter to 80 ° celsius to bring it on the shaft

It is made much to tight, so I was not able to bring it on the whole shaft.

Motor End Yoke Adapter is "done"

EVDrive 01/2012 test run with 70 LiFePo4, the Soliton1 and a WarP9

I have to change my machinist.

The work lasts too long, it is not ready and he is on holidays now...

Motor End Yoke Adapter with the 1.125 inches drilling

My mechanic says in a week ...

That means, perhaps in the end of this week....or the beginning of next week...?...

End Yoke

It's looking like the end yoke has to be done in a special production.

Universal joint

I need a end yoke for a 1.125 inches shaft and a 0.250 inch keyway, that fits to my Koyo U joint.

The Dana 1310 is much to big.

Original Koyo U joint in the Grizzly

A= 64mm

B=57,1mm

D=25mm

d=14,67mm

LI= 43,7mm

Direct Drive

I will try a Direct Drive test with a WarP9.

First quick motor size check
