John Williams Daihatsu Car 4 May 08

John is one of the growing number of EV in Australia. He runs the website EV (link at end of article) and has been useful feedback on this via comments for some time He is putting the wraps on his current EV based on a two seater Daihatsu (it wasn t always a two seater: he the back seats for batteries).

specifications for the EV Conversion:

Controller H2 120V 600A with braking

Motor Advance DC

Charger Zivian H3

Batteries 10 12V lead acid total of (1,200lbs)

A look under the or bonnet as John would

I took the liberty of taking the on the left and marking up the components. will have to jump in and me, as I wasn t quite sure on the and really guessed that the far item was a circuit breaker. sent along an annotated which better shows the and includes the ACC battery.

What I was a circuit breaker is the reversing (double throw, double One of the benefits of having a regen like the Zapi is that you get reverse as a bonus. BTW. the on the controller is a mod that steps up the max capability from 96 to 120vdc.

at some point we can whip up a schematic as well, especially this EV features regenerative which changes the wiring.

As any EV conversion there s often a curve or misunderstanding and John s was no I didn’t realise that the used full pack to drive the contactors and I used with 12V coils. To cut a long short I cooked one contactor and the board. I think I’ve the damage down to a track, 3 and a driver transistor. Hopefully I can it otherwise I’m up for a new logic board or

These two photos show the area of the controller s logic John, being an industrious managed to fix it.

Replaced 3 diodes, a power and a bit of jumper wire for the burnt out totaling $5. It’s now working, a lot than $999 that a place quoted me. In fact I got together and took the car for a short drive last night. It

The Zapi H2, since it is a regen is wired directly to the relays so as to which relay is on and when. was the case with the Zapi H3 was used for a bit on my first EV as you can roughly see on the diagram I put together back

And now for the big challenge: where do you put a thousand of batteries in a small car like John got two of them up front the motor and electronics and the other are now passengers in the back seat and I really like the battery box and John about it:

Battery box was by my neighbor who is a steel fabricator/sheet worker. It s made out of aluminum of and took him about an hour to and weld up while I fixed his network. It will have an lid once he gets around to it for me. It s not hard IF you know how to weld

Being aluminum I have to it with an acid proof or give it a rubber lining to get to the licensing inspection. Underneath it is a frame to give it support will be bolted to the floor of the I ll take a picture of that I remove the batteries to bolt in. At the moment they are just there and everything tends to to join me in the front seat I stop.

As for lining a few folks in the have suggested using the rubbery stuff they use for bed liners. You can buy it in spray cans and in gallon cans to spread on Click the photo to see one of the types I on Amazon.

The batteries are Supreme ( PDF ) deep CR 185 s. They cost AU$3000 for 10 AU$200 shipping from to Perth. They are REALLY at 55kg (121lbs) each.

A of the interior wiring in-progress. can jump in with more on what he s using for instrumentation.

As earlier the H2 is a regen controller and has wired it to eventually use the regenerative but hasn t yet tried it out. One that needs to be done is to change the advancement of the electric brushes. Most DC motors with the brushes advanced a which is fine if you only use the to generate thrust.

Once you using the motor to generate this advance is the wrong way and the brushes to arc. ADC motors can be and it is suggested that they are put to zero advance, which a better balance between and regen, saving wear and on the brushes.

So far John has driven the EV a bit, but he s (wisely) holding off on test runs until the pack is fully secured. for sharing John. Be sure to by and see John at EV Australia .

Thanks for doing up the Jerry.

I took the car for a longer drive on the weekend, about Very happy with the

Acceleration from 0 – 40kmh was and way above the original car.

from 40 – 60kmh was slower but reasonable.

Acceleration from 60 – was reasonably sluggish but acceptable for a

The above was done with at about 1/2 charge. I have wired in the battery charger and give them a good and see how that affects performance.

I pushed it past 80 yet as I still to work on the rear suspension and I really feel every or dip in the road.

Currently I have anything with the instrumentation so have a charge meter or amp gauge. I do have 10 separate LED indicator circuits which I’m of wiring up until I get a real gauge”

Nice going into the car and Jerry I like the one click zoom on the images.

Hi John.

What great I am moving from a 96V Zapi H2 to a Electric Zilla. I will the regen. It s very satisfying the ammeter go into reverse you put your foot on the brake.

I am to hear about your mistake. That must been quite expensive!

car will be very similar to my Rover Metro which was but did work well. I never got to the 120V upgrade.

JohnW May 05, 19:55 PM #

Fortunately the mistake cost me about $AU200 all up. for a new contactor, $5 for repair of the ZAPI and $90 for 3 relays to drive the existing

I’m working on an updated wiring that I will post, based on the one you gave me James so look fairly familiar. thanks for giving me that it a lot, I just should checked with you on which to use :).

James May May 06, 2008 08:08 AM #

I d have been able to you to use HV contactors.

Please make your flooded batteries are vented whilst charging. You saw happened to my car. There s a of the bonnet area on Jerry s page.

I wish I d fitted a smoke detector too.

May 12, 2008 03:41 AM #

The smoke is a great idea, I’ll to see if I can add one to the battery compartment and the cabin. I don t a choice with the venting, all EV s in Australia have to be inspected and venting is one of the requirements to get it road as are a few other safety features keeping acid out of the drivers etc.

Gavin Shoebridge May 12, 2008 PM #

Very nice work on the John!

Jerry May 12, 2008 PM #

and you are both from down Coincidence? I wonder.

JohnW May 12, 20:59 PM #

Hi Gavin, Actually the way I at it is that WE have it the right everyone else is upside 🙂

BTW. If you don’t mind I’m to add a link to your page my site and add you to my EV map.

Took it for test drive on the weekend. Did with a top speed of 100kmh. It have done more easily but I didn t want to get for speeding. I ve gotten used to the now and acceleration is actually very across the entire speed if I use 3rd to start and move to 4th at about After the trip it took 4 hours to charge with the set up for a 175AH pack (mine is 185AH).

I think it was charging at a less than a 10% rate so would make it about 40% Not too bad considering I was accelerating hard and at speeds higher than I normally. I really do need to get a good set of instruments though to it out properly.

I’ve order a set of springs for the back end which be ready in 2 – 3 weeks, it’s to get anything manufactured any quicker here because of the mining Once I get them in I’ll be and ready for inspection.

JohnW May 27, 03:15 AM #

I m picking up my heavy springs this afternoon. ready to go for the inspection.

I m a student and I m a 1974 Porsche 914 to an EV. I need to my controller and don t know how to. Its a Kodiak do you have any suggestions?



JohnW Jun 04, 20:15 PM #

Hi Justin, I don’t anything about the C600, voltage is it? Do you want to test is you think there is a problem or do you want to check your I seem to recall that people have tested the by connecting the controller to a bank of wattage globes.

What I did was to wire everything up except for the itself and then switch on and for smoke. I was successful on the very attempt, ie I got the smoke I was looking for 😉 I repaired everything I tried and when it didn’t smoke I carefully used a multimeter to the voltage everywhere and then everything off and wired in the motor, up the car and gave it some juice. though read through my posts above, watch out for high voltage it can really

Most importantly though, I advise you to post up your diagram showing the actual and voltages etc, it would saved me a lot of headaches if I had done

Donald Morrison Jun 09, 2008 AM #

Hi John I am like most interested in a EV I have a friend drives a toyota ute converted a 120 volt system and it runs well also use it to pull out his boat that he use to take around boston bay in Port however I intend to build a car my have some information the net would like to hear you have to say regards don Morrison

Hey thanks for getting back to me. I ve been trying to test it to see if the works. Its operating voltage is 55-144V at a max current of 680amps.

I it up to a power supply and a few multimeters and it power. I just want to see if it like its suppose to. I ve been making a test stand for it, the power supply, etc to make it all works before I put it in the car, and to see new parts I need to buy. I the electronic components out of an old ev jeep and I m not what works and what

The good thing is, I recently all of the wiring diagrams and you re right it does help!

JohnW Jun 12, 22:52 PM #

Hi Don, The first to do is make a list of exactly you want to do with the car. I did a one with 2 columns, 1 The absolute 2 The preferred. That way you can balance out the versus performance while guaranteeing that it is useful.

Pay a to my site ( http://www.evaustralia.com.au ) if you want more details on my conversion. I’m than happy to answer any you have.

JohnW Jun 12, 2008 PM #

Hi Justin, Just be really that you have the motor down. It will want to off the table or spin round and up all your cables when you power. I put just 12V on to my 120V and that wanted to take off the floor.

anyone have an electronic of the Zapi H3 manual that wouldn t mind emailing to me.
