Mirror Removal - Legalities?

I have had a few old cars 1962-1970. For them, if you completely remove the mirror, there is no problem with rego. ADR 14 (From July 1988) seems to be the relevant one: http://www.infrastructure.gov.au/roads/motor/design/adr_online.aspx Looks like you can ditch the passenger mirror in 7/88 onwards c...

Hi Power Batteries

I made enquiries with: China Hipower New Energy Group AKA China Shandong Hipower New Energy Group www.chinabatteries.net and www.chinahipower.com.cn mostly because they have 10Ah and 20Ah LiFePO4s, meaning a 415V AC industrial conversion didn't mean $12,000 of TS LFP40AHA. Has anyone seen/heard any ...

Hi Rod,

Power steering?

Welcome Amanda, another way to keep power steering is to get an electric power steering pump. The toyota MR2 has one, which I think will work with just about any normal (hydraulic) power steering. Other cars with pure electric power steering include the Holden Combo, and therefore possibly other Ope...

Car choice - drag coeffiwhatsie?

From my mucking around with EV calculators it looks like air resistance only matches rolling resistance at 60mph, and is double rolling resistance at 90mph. Rolling resistance is proportional to weight, and constant for all speeds. (edit: Um, this only holds for really heavy cars, like PbA conversio...

Prices for LiFePo4 Batteries

I don't know much about the BEV BMS, except it's $28 and from Blade Electric Vehicles (BEV). BMS can mean Battery Monitoring System or Battery Management System. I think a BMS should "monitor" the cell condition (voltage/State of Charge/ Temperature etc.) and "manage" (electrically do something to p...

Prices for LiFePo4 Batteries

Hi Hyper24, yes, would be cheaper for the same size (kWh) pack, but the voltage would be twice as high. (or you'd have to run the cells in parallel, which I didn't think about until now). Factoring in the BEV BMS: LFP40 @ $55 + $28 = $83 = $2.075/AH LFP90 @ $140 + $28 = $168 = $1.867/AH so the 90s w...

dc motor-good,better,best

Hi Vince, welcome to Australian EV land :-) I'm a recent convert too, but I think I can accurately regurgitate the information I've read. 1. DC series wound motors - the majority are "Advanced DC" or "Netgain Warp". The Netgain are heavier wound which gives a peak power at higher RPM. I think a Warp...

My understanding is that, Europe, UK already had an intermediate registration class between a car and a motorbike - a "quadricycle". I think this has none of the crash requirements of the car rules, just a weight limit, which the EVs can get under using modern materials. UK I think historically had ...

dc motor/dc generator,

More or less, yes, if it's a permanent magnet motor, but a device designed to be a generator should do a better job per dollar than a device designed to be a motor. Wikipedia has heaps on generators and alternators. You can put smooth DC into a motor, but you won't get smooth DC out of a motor. Also...

Regenerative braking

Hi Acmotor, I think it would be more natural to have some (or even all) of your regen brake available through the accellerator. ICE jockeys are used to some slowdown when you take your foot off the loud pedal. I heard that the AC-150 switches the brake lights on if the car is decelerating at more th...

Brett, none of your points grate with me, mate :-) The biggest incentive for EVs that I can see is that you don't have to pay fuel excise on your fuel. I.E. the fuel users are subsidising the EVers. I have no idea how big this is, though, so lets work it out: http://law.ato.gov.au/atolaw/view.htm?do...

I think I'm getting a handle on this maths and my high school Physics. If said vehicle is the vehicle I think it is it has tyres same radius as 185R14 = 185/82R14 -> radius of 185*0.82+14/2*25.4 = 329mm = 0.33m.

as far as I know in NSW you get 2 meters, 1 for your off-peak circuit, 1 for everything else. Everything else is always charged at the normal rate, your off peak stuff is charged at the off peak rate, but it is switched on only during off-peak time. There is a new scheme which you are put on if you ...

Direct drive points.

Striker,

I think the ideal car for you is an Escort panel Van:
1. Ford - a real ford, not a rebadged mazda
2. light weight ~750kg.
3. high load capacity for batteries
4. rear wheel drive for drag racing
5. cheap

Compliance for pre-ADR cars

Hmm, just read NCOP 14 again, a nice little phrase in 2.8 is "increase in
weight" -- hopefully if I don't increase the kerb weight, all should be OK since I won't be increasing the strain on components :-)
