Electric Hilux Ute for sale by reverse auction.

With much reluctance the time has come that I would like to move on to my next conversion. To do this I need to make space and sell the Electrolux, my electric Toyota Hilux.

I am holding a reverse auction on the AEVA site if you are interested.

See this site for the auction. Starting price is $5000, reducing by $200 per week.

It is the first road legal industrial AC conversion in Australia.

50 x 20Ah batteries
ASEA 15kw 4 pole aluminium frame motor
Danfoss 5042 VFD
Peak power is 48kw, Peak torque is 360Nm
Seats 4
rego till March (need to check)
located in Sydney Northern Beaches

It has been on the road for 18 months.
The batteries are good for only about 9 km on a warm day. The inverter sometimes takes a while to start in damp weather, but it always starts after about 5 mins to warm up.

This would be an excellent EV for someone to build on and develop as it is already registered as an EV. Or use as a technology test platform for a company.

There is plenty of room under the bonnet and in the tray to easily experiment with different configurations without having to shoehorn in components.

With a 100v motor rewind, a tritium controller and a 320v pack of 40-60Ah Lithium this would be a great vehicle.

Check the old posts in my blog http://a4x4kiwi.blogspot.com for the build details or check the June 2009 edition of Silicon Chip magazine.

Energy storage in capacitors

Energy storage in capacitors

A nice mathematical and practical comparison of Battery and Capacitor stored energy.


Super and ultra capacitors have a way to go.

A 3000F 2.7v from Electronic Goldmine can hold 10.94k Joules of energy: (1/2)*C*V^2

This is only equivalent to the energy stored in a .95Ah 3.2v Lithium Iron Phosphate (LiFeo4) Battery: V*Ah*3600.

Lets hope that Eestor are not vapor -ware.

Optus Cable upgrade to DOCSIS 3. Wahoo.

Before:



Using Free Download Manager that downloads files in multiple parts, I can get about 960kB/s or 7.68Mb/s

After the upgrade, I get the following. 7 x as fast!

Using parallel downloads I now get about 5MB/s Thats about 5 times what I had before. All for the same price I was paying. Thank you Optus.

Think I will just back up the internet.

This is what I get from the Optus site.

i-MiEV Mitsubishi electric vehicle Frequently Asked Questions

We had a show-and-tell of the i-MiEV this morning to the staff. These are the most frequently asked questions.

Q: How far can it go.
A: About 100 km

Q: How fast can it go
A: 130km/hr

Q: How long does it take to charge?
A: About 1 hour per 15km driven. 8 hours from flat.

Q: Where can I charge it?
A: from a 15A power point. These can be identified as they have a larger earth pin than the other 2 pins (normal household power points are 10A)
Q: Where are the batteries?
A: Under the floor.

Q: Where is the motor?
A: In the back under the luggage compartment.

Q: How do I know how far I can drive?
A: The is a 16 pint ‘fuel’ gauge and a trip computer that estimates range left in km.

Q: How much does it weigh?
A: 1080kg

Q: How is B different to D?
A: B provides more aggressive regenerative braking when you lift you foot of the accelerator?

Q: Does it put power back in the batteries when you let your foot of the accelerator or you press the brake?
A: Yes. AC motors in electric vehicles provide regenerative braking.

Q: What if the battery goes flat?
A: Call a tow truck or plug it in.

Q: How much does it cost?
A: We don’t know, they are not for sale yet in Australia. Roche is privileged to be on a special lease program from Mitsubishi for 3 years. As an indication they should be less than USD 30,000 before rebates in the USA.

Q: How much pollution does it cause charging?
A: 1/4 of CO2 compared to ICE (Internal Combustion Engine) equivalent

Q: how much does it cost to run?
A: 1/3 of the cost of an equivalent ICE. 1/9th if charged off peak.

Q: Is it quite?
A: Yes, 5dB lower than ICE. About 1/3.

Q: Is it safe?
A: Yes, it has a 4 star NCAP rating with dual airbags. If fitted with Side and curtain bags, will be 5 star.

Q: Where can I find more information?
A: From Mitsubishi. http://www.mitsubishi-motors.com.au/microsites/i-miev and for more technical details from this presentation http://www.mitsubishi-motors.com.au/microsites/i-miev

Photo essay of the Mitsubishi iMiEV elecrtric vehicle.

Below are photos of our newly delivered Mitsubishi iMiev.

Starting from the front, The headlights are HID.



The small exposed condenser is for the air conditioning.
The heater uses an electric water heater rather than reverse cycle air conditioning.



Due to the the windscreen geometry, there is a single wiper to clear the entire windscreen.



What little electric vehicle maintenance there is consists of checking 3 fluids.
Left: Windscreen washer fluid
Center: Brake fluid
Right: Interior heater fluid



On to the interior. There is plenty of room for these lads. Obviouisly no center console but this is made up for a lot of headroom for a small car.


The dash cluster is quite sparse.
Left: Energy gauge (16 bars, currently full) and drive mode (P for Park)
Center: Digital speedometer surrounded by economy gauge. Blue means regeneration. Green to white indicates more energy usage.
Right: Odometer/ Range left / A & B trip meter/Service / and dash illumination. This is controlled by a button extending from the dash cluster



There is a bunch of warning lights to the left and right on th elower edge of the dash cluster. On the left there is Battery (presumable dc-dc converter), limp home, traction control, 'engine' fail. These appear momentarily when turning the key on.


On the right the warning lights are door open, seat belt, air bag, brake / park brake, ABS and EPS (Electric power steering)


The stereo system has a nice touch screen, but unlike the Prius, does not proved any vehicle integration. It would be good to have nerd mode to show battery volts, current, power, torque, trip computer. It does have bluetooth hands free for your phone and also a navigation system.


In the glove box there are RCA connections for an ipod of DVD / game console (Left Right and Composite video). There is also a USB socket for a memory stick or hard drive. I havnt tried it yet, but the stereo seems to have a Divx decoder built in.



the pedal box is compact and seems comfortable enough. I have to wonder why there is a block of polystyrene to the right of the accelerator.



To the right of the steering column are a TCL disable (Traction control). not traction control is required on all new cars from 1 Jan 2011.
Next there is the read demist, and the electric mirror control.



The gear selector has 6 positions.

P: Park
R: Reverse
N: Neural
D: Drive
E: Economy. Same as drive with lower power limit.
B: Same as Drive but provides more regenerative braking.



Next we have the charge socket cover release lever.
To the right of the drivers knees is a pull leaver that opens the 15A charge socket.



15A charge socket on Right rear of vehicle.



Under the drivers seat is the fast charge socket cover release.



the fast charge socket is located on the right rear guard of the vehicle



The rear seats fold down to increase luggage space.
the floor behind the rear seats is quite high in order to accommodate the inverter and charger.



To be continued: The next write up will be the test drive.
