CVT & IVT Gearboxes

The CVT gearboxes from Jatco that are used in the Honda Civic and a Japanese only Nissan (I think) are extremely heavy at a bit over 65Kg. I agree with ACMotor. What we need are high torque, low speed motors for direct drive to the wheels. Gearboxes should be eliminated for efficiency gains and weig...

Holden Aust to cap fuel prices

Chrysler in the USA has a similar scheme to get people to keep buying it's gas guzzling monsters. From what I can see, it's not working that well. People want a real solution to fuel costs and seem to see this for what it is, a band-aid. Two years will skip by pretty fast and then what have you got?...

$6000 EV

6K eh.... I would think if you were making a thousand you might be able to work the costs down to a mark around there. However, the least expensive conversion option is using a DC motor and controller. Series DC motors are mechanically and electrically inefficient compared to AC so in some ways it w...

I saw this manufacturer mentioned in another thread.

Does anyone have any experience with them and possibly pricing? The pack itself looks very useful.

Capacitor banks

The guy that runs metricmind.com has fitted ultracapacitors to his EV. They are connected in a similar fashion to youe second diagram from what I recall. The idea of using the caps as a source of instant hight current is definitely valid and as Peter C points out, the source impedance of a capacitor...

$8/L for petrol!

The market will have moved long before petrol reaches $8 per litre. There is going to be a big shift when it hits $2 per litre. People will be buying smaller more economical cars and in the medium term, less demand will force a price drop. The japanese car industry got a foothold in the USA during t...

EV first timer

The Honda CRV would be a good candidate. They have a really big rear differential set up. It's not just the diff, there's something else hanging off it in the front. Anyway, that would be a good place to put the motor. Good luck on your project. AC and LiFePO4 is the way to go if you want to do a th...

Yeh, I don't like trikes either. They have some good features, mainly aerodynamic but I still dont like the idea of a single rear wheel.

Don't go hybrid to save money !

I agree with the general sentiment but consider if you purchased the hybrid second hand (as I did) and then factor out the normal new-car depreciation. You can't argue with a full four seater that can achieve around 4.9 litres per 100K. The regular vehicles that can achieve this are either diesel or...

Yep, you're right Richo. There's no doubt about it, the whole LiFePO4 argument keeps coming back to Thunder Sky. There isn't a comparable product on the market apart from LifeBatt stuff as far as vehicle use is concerned.

Just as a follow up to this. It would appear that the vendor is having shipping problems due to the Olympic games in China. So don't be surprised if your order takes a while to arrive.
