seligtype3 1969 Volkswagen Type 3

If the rear section of the frame around the motor was a removable section from the main frame the motor could be fitted and removed without removing the whole assembly.

Howto convince your partner to let U build an EV

Richo: Is that the one where at the end one of the guys (an oil futures trader prior to the crisis) is driving his hummer around, behind a pair of large horses? That was hilarious. Yep that's the one! I remember that but it was more than a couple of years ago. what was the name of it? T1 Terry

Often if you take the ignition switch with you to a locksmith they can recut a key that won't pull out in the on position. You then put that key away for rego time Image

How low do you go?

Terry, I have a concern that you are placing more emphasis on the 600A regen than it deserves. You won't get it that often and certainly not for long. 57kW of regen sounds a bit painful. What are you trying to stop? 10 tonnes of motorhome or actually converted bus. 11mtrs long, 3.8 mtrs high and ro...

Quite right Johny, sort of thinking in print to get some sort of balance to the project and get peer feed back from those with a lot more clues on this stuff before I dive in. My first thoughts were toward an electro magnetic retarder but then I looked to a method of capturing that waste energy and ...

There's always more than one way to skin a cat but there's also an easy way and a hard way. The torque wrench on the plate bolted to the coupling would still work, a suitable rated torque wrench can be hired cheaply. Doing the bolts up and undoing them later from the diff end would be a long slow pr...

EV2Go's - Lithium Powered Trike

The bolts are already through the coupling as you slide the motor and torque tube onto the diff. The bolts are located and tack welded to a plate at the motor end so they can't spin and some form of retainer like a circlip stops the plate from sliding back toward the motor. This way the threaded sec...

How low do you go?

Just for the exercise I went through the numbers, to absorb 600amp regen @ 96v would require 2112 cells, @ $7.99 = $16874.88 plus freight from the states, maybe not. They do have a 4C recharge and 30C discharge spec though.

Won't heat be an issue? There are some very nive air vents that feed in from each side already there so some adaption the these would help. Is the controller air cooled or water cooled?

How low do you go?

The TS specs list max charge current 3C at -45degc to +85degc. If regen is equal to max motor amps I could need the batteries to absorb up to 600amps without the terminal voltage climbing to cell destruction. The Headway cells look great for 600amp draw with 5C capability I need 12 in parallel x 32 ...

Lithium Sulfur Batteries

According to Jack Rickard TS have told him they would have batteries available to him mid next year for his latest monster project. Still not sure how much strength to place on any of that but time will tell.
Were they lithium sulphur the power cells that were used in the Mars explorer?

Hi Johny, I've been trying to find spec sheets for Headway cells but I must be looking in the wrong places. It appears the A123 cells are unobtainium unless you buy heaps of electric drill packs and pull them to pieces, that doesn't sound cost effective. The Headway cells seems a little blurred too,...

A mix of Valvoline Tectyl, fishoil and diesel will make a far better rust proofing agent than tar. 50% Tectyl, 50% fishoil and a further 10% by volume of diesel, best to add the diesel just before you plan to spray it to avoid evaporation and settling.

How low do you go?

call it 115 kW electrical, or 157 A for a 730 V nominal pack, which is 4C). Of course, the pack will sag to way less than nominal, so we'll probably need around 6C peak. We're hoping that peaks of 6C won't reduce the life of the pack too much. If the TS 40ah batteries are rated at 0.5C standard (se...

C/4 = 0.25C is quite far from savage discharge (actually its almost bang on ideal). Bugga, have I been caught by non consistant quoting of measurement methods again, so C/4 is the capacity divided by 4.
