Re: Around Australia Electric Highway

The Around Australia Electric Highway is suitable only for EVs with 300+ km range.They (AEVA members) have done well to get the 3 phase sockets in lots of places such as roadhouses. Long range EVs with generous on-board chargers can do really well with this infrastructure. However, my LEAF (and othe...

Re: Around Australia Electric Highway

I often see a mention for this and "Qld electric highway" being for any electric vehicle. There is now, and there always will be, EVs with 100km range.

The WA "electric highway" works well with DCFC spaced around 80km apart.

That particular service station was already into EV charging a few hears ago. I charged my LEAF there (with an extension lead) in August 2016 on my way from Collie to Beverley Agriculture Show.

Well done Matt, Ali. Thanks Geoff. Williams local Council was extremely friendly when I was there last year. 240V outlet available in the Lions Park (PlugShare) near the bridge for us little EVers.

Re: Classic EV Conversion - Daimler 250 (V8)

If anyone has the time and knowledge to answer a few questions I would be sincerely grateful. 1. I am reasonably handy but not a mechanic nor an electrician. (I can build and fix things.) How much of the work could I possibly do myself? 2. What kind of a set-up would you recommend? I’d like to have...

Not wanting to sound paranoid, but....

If I wanted to steal your login and password (in case you used the same one for banking), I would hijack a program that accesses the web and present a forged web page of the same (copied) design. And ask for a confirmation of username/password.

Also your "3" was "E" backwards which, I think, would appear ok as a "3".

Evening,

I go into new posts and read the ones that interest me.

Re: Off-grid EVSE

Yes, I can see that it would be like PWM with the controller cutting in and out. As I would be doing the EVSE controller from scratch (PIC microprocessor) I much prefer to "follow the sun" with 1A resolution. I am happy to use the battery voltage as the indication of state of charge. I have a separa...

Re: Off-grid EVSE

As I understand the issue, this regulator may solve the problem of charging the vehicle only when the main battery bank is full or above a predetermined voltage. Any processes can also be turned off when either the main or secondary battery banks drop to a certain voltage or SOC. If you google Plas...

Hi. I just got back to reading this forum. Since the layout change I had struggled to find the "new posts" option. The answer is NO, I have not yet built this charger.

Anyone run their EV from home battery storage?

As we've talked about on the other thread, you are most likely going to be stymied by the 6 Amp lower limit on EVSE. The Leaf/iMiev chargers most likely will not go below this. I wonder if another idea might be to create a low current CHAdeMO charger - totally current controllable? I have installed...

Larry Mudd charges his iMiEV from stored PV, and I believe Jeffthewalker (Jeff Johnson) charges his Leaf from an off-grid system in Beaudesert Qld. Yep, charging from solar/storage as we speak.

Off-grid EVSE

    All very interesting but currently way to technical for me. First I wish somebody would answer the following question: is there a basic problem to charge my iMiEV with a run of the mill DC to 240 V AC inverter (off grid solar +batts). Can it damage the onboard charger or the batteries of the EV...

What EVSE to replace dead Origin/ChargePoint?

That's a 50 Hz transformer. You don't see many of those any more. [ Edit: in consumer goods. ] Transformers only work on fixed AC voltages, in this case 230 V and 19.6 V. Without a lot of work, the best you could do was a transformer with 2 120 V primary windings, and a double pole double throw swi...

What EVSE to replace dead Origin/ChargePoint?

You may need to get help from someone familiar with mains work; you need to be safe, and ensure that the final product is also safe. An EVSE is essentially a switch (relay) and some electronics to turn on and off that switch, so it's not complex in there. [ Edit: added "carefully". Safety first. ] ...

No Jeff they wont.... Thanks Reecho. I know that my 15A JuiceBox can take a range of AC input, including 120V.

I am looking to ease the burden on my off-grid solar/battery system. I will be installing a 120V pure sine wave inverter. The reduced voltage will enable me to draw 720W from my system (120V X 6A). Further down the line I will design/build an EVSE that will increase the amperage draw if the system h...
