EV economics

Bidge, I expect that your kit will be a DC conversion. That being the case, any electrician worth his salt would be able to sort it out. From the safety standpoint I'd recommend this if you don't have any experience with this type of thing. Even if the battery pack is 144V, it will still be able to ...

LiFePO4 Battery Life Cycle

LiFePO4 chemistry is relatively new and subsequently not much full scale testing seems to have been done in vehicles. The depth of discharge (DOD) that you subject any battery or cell to will affect its cycle life. Generally, the figures that seem to be bandied about are 2000 cycles plus at a DOD of...

Petrol tax reductions

I know I'm going to sound like a defeatist here but I have watched the party political process for many years of my life. My considered opinion is that if you want the ear and assistance of the gummint you have to be one of two things. Thing one is a "Big Player". That is why Toyota and Mitsubishi h...

TIG as a charger?

Water cooling for AC induction motors is mainly necessary where the motor needs to be compact or is in a housing that permits little airflow. The Siemens motors that you have seen on metricmind are either bespoke automotive motors that have been made obsolete by Ford et al, scrapping their EV lines....

What about an EV hybrid?

Doesn't that bring us to the other "pie in the sky" alternative. The hydrogen fuel cell. First of all, where do you get the hydrogen? Why you get it from either cracking petroleum gas or from water. This requires an energy input, in the case of hydrolysis, electricity. Then you take your Hydrogen an...

Petrol tax reductions

Every time the gummint gets involved in a problem that is market driven (petrol prices) they stuff it up. They arrive too late and apply the wrong leverage to be effective. Usually this results in the wasting of taxpayer dollars. Reducing the fuel tax will do nothing. In a few months, the price will...

G'day from another newbie seeking advice

All the SVX's were autos, never one made in manual. The Vortex should be a cheapish conversion but I thought they looked out of date the week after they came out!

I work in commercial radio broadcasting. I'd say the best way to get some airtime is to present the news room with a press release that is pretty much a news story. Keep it short and concise.

60s Model Mini Minor

The biggest problem I see is the Gross Vehicle Mass, which has to stay within a prescribed amount. I'm not sure if there is a tolerance in the GVM but the 60's mini weighed around 600Kg so it's going to be interesting trying to keep the weight down. A lighter car needs less Kw and less Ah so I guess...

I don't think you're wrong Mark. I think an AC conversion could be in the same ballpark as a DC conversion. In addition to that. There are a huge number of second hand AC motors out there but very few DC. With some shopping around, you could probably find an AC motor for less than the price you esti...

Just to clear a few things up about PM AC motors. Firstly, demagnetising your PMs can occur but only in a badly designed motor. Interestingly, heat will cause demagnetisation not the alternating field. Cogging problems can be overcome by increasing the number of poles. 40 and above seems to be the m...

Personally, I'd hit the auctions for a donor car. Your biggest worry at the auctions is some form of hidden mechanical problems, mainly engine. So if you were doing a conversion, you wouldn't give a toss about the motor as long as it got you back to your shed. I'd be happy if I NEVER went into a use...

Too much of a city car for me but I'm really pleased to see it going into production. It just goes to show how legislation can make a market. The poms have legislation that's friendly to EV's in London. As with the EV-1, legislation was the spur, not the market.

Some very good input on this thread. I disagree with the choice of vehicle. If you want a TV host to drive it, you'd be better off with a flashier car than a "whitegoods on wheels" type conversion.
