Thread: Goingbush's Electric Vehicle project

How about mounting the socket on a bracket in behind the front number plate somewhere?

Chris

Battery Boxes made from folded and welded 1.5mm steel .
Trial fitting before I work out the mounting brackets.


All boxes are 320mm high to accomodate 280mm high cells plus room for wiring & clamps. Front box containing 12 cells, sits below the top of the chassis to lower center of gravity, but not so low that the diff will touch it .


mounted behind that is a box for 9 cells.


Underseat boxes hold 12 cells each, they are a tight fit width wise.
My 45x 200AHA prismatic cells have arrived at the Australian importer Home , just waiting for delivery.

This is a fascinating project.

Electric cars need drip trays as well??

Might have to start using sawdust !! I do have a seal kit for the gearbox, I best put it in before its too late !!

Woo Hoo, Batteries arrived . no excuses now . Time to get stuck into project

Test fit in one of my Under seat boxes , once I put a bit of coreflute around the inside edges it will be like a bought one.
Wasn't until I put the cells in the box that I worked out how I'd be clamping them down. I think I'll put 3 x lengths of 1/4 All-thread from side to side and squeeze the box sides in on the battery pack. They say to pack them nice and tight to stop the possibility of swelling during charging.

Mounting the front boxes is a pain , remembering they have to take 12G in a frontal impact to satisfy VicRoads . Meaning any occupants will be dead , but they want batteries contained, not necessarily intact .

Front box is great , it sits below the chassis mounted into oil cooler chassis tabs 4 x 1/4 UNF bolts , total sheer force 4000kg (only need 1500kg total) & the two 1/2" UNF shocker bolts at the rear of front box , something like 10,000kg sheer force.

Mounting of rear box is a problem, I have to mount it high to clear the motor & offset to one side because of steering box arm , This gives me a place to mount my 40Ah 12Volt Ancillary battery ( Golf Buggy battery) .

A bit more progress.


Hopefully the lengths of all-thread which pull the sides of the boxes to squeeze the cells tight together will suffice as a clamp.


Interestingly that small 12V SLA 18AH weighs more than one 200AH Prismatic cell !!
