Re: Hot rod EV - looking for advice.

I am converting a Pajero which I think is about the same size and weight as your truck. The Pajero has independent front and rear suspension which makes it easier to connect the motors to the diffs because there is no need for a long tailshaft as the diffs don't move. This leaves more room for batte...

Re: Tesla for sale 30k jeg in gumtree

My father used to buy damaged golfs fix them and sell them. This is what I know about the write offs. In Qld the determination if it was a write off is done by some inspectors at the Auction site. They look at the car and make a judgement if the car has been damaged enough to be a write off and if i...

That is for the left hand drive version :lol:
Ask for the right hand drive version. :lol:
I bet they didn't put on the drawing if it was the engine view or the gearbox view.

I may be able to help but I am in Brisbane. I can machine the flange and possibly cut external splines.

Re: EV BATTERY DISCUSSION AND SUGGESTIONS

The cooling system is part of the structure that holds the battery together so that saves weight by not needing the battery case to provide the support. It is also very light and strong because of the shape. Because the cells have the tabs on opposite ends I do not need to put a heavy copper bus bar...

Re: EV BATTERY DISCUSSION AND SUGGESTIONS

If I use the 63Ah cells I get higher energy density than using the Tesla modules because the battery box is very light as it does not have to provide mechanical support for the battery pack. Also I can make the pack suit the space available. The 63Ah cells are new and the cooling system is far super...

Re: EV BATTERY DISCUSSION AND SUGGESTIONS

How many kwh do you need? I am trying to get some people to do a group buy to get the price down for the freight. The cells I want to buy are 3.6v 63Ah. The price per cell from the supplier is US$45. I also have developed a cooling system and all the mounting hardware which I can sell to you as well...

That is on the list. Seriously. I am thinking of using the air con to chill water and then run the water to whatever needs cooling. So running a beer fridge on the front is easy.

Re: Francisco's Electric Pajero

1.2mm steel. I was thinking of using steel and then powder coating it but I think the cost of the powder coating will be more than the extra cost of using stainless steel. I am not sure if it would be a good idea to make it out of aluminium. The total weight of the box in steel is only about 40kg so...

Re: 2011 nissan leaf

One less hurdle for electric cars. Everyone was worried about the cost of replacing the battery when it gets too old. It turns out that it is much cheaper than anyone expected and as more second hand electric cars become available there will be an incentive for aftermarket replacement batteries whic...

Re: Francisco's Electric Pajero

I have been a bit busy working on the battery case. The battery case is proving to be a bit slower than I was expecting. The main reason is the time it takes to get parts laser cut then folded then I have to assemble and check that everything is right. Because I do not have an accurate 3D model of t...

Re: Prelude conversion project - some questions

I am saying they could easily offer say a Nissan Mira or a Honda civic or a Toyota Corolla with electric drive train and a 25kwh battery without having to develop a new car just bolt an electric motor instead of the petrol engine and a battery instead of the petrol tank. Just consider how much it co...

Re: Prelude conversion project - some questions

6kw isn't much. It would easily fit in the engine bay. I am just thinking of the viability of manufacturers to offer electric drive as an option to standard cars. That would make the development cost very small.

Re: Prelude conversion project - some questions

This is looking really good. The battery fits so well in that spot.
Makes you wonder how hard would it really be for car manufacturers to offer an electric drive train on standard models as an option like they do with diesels and LPG.

Re: Hybrid drive caravan?

I did not think it would be a driver-less vehicle because it would not run unless it is connected to the towing vehicle. So it will be driven by the driver of the towing vehicle. So say if you disconnected the plug for the tail lights then the motors would be disabled. The Caravan would stay behind ...

Re: Hybrid drive caravan?

I thought of this idea a few months ago and was told ADR would not pass it so I didn't think further. I wanted to put a much bigger battery. More like 100kwh and 6kw of solar panels. The idea was you can go full electric. The caravan would feed the electric car and its own motors. When you run out o...
