Re: How DC chargers work

Thanks jonescg. Your figures make sense.
I just asked because of reports like this:

Tesla explains why it limits Supercharging speed after high numbers of DC charges

Re: How DC chargers work

Are these proposed 350kW, and possibly 800kW charging stations, predicated on the general adoption of solid state and/or ultracapacitor batteries? Wouldn't current Lithium-ion batteries be seriously degraded by the heat generated (unless charging rate is drastically controlled)?

Cheers

Re: Zappi EVSE

Hi Tassie6er Wow! Your Model S must be capable of return journeys to any point in Tassie on a single charge. Tasmania must be the ideal state to own an EV, with reduced range anxiety and with the grid mainly fed from green hydro. How long does it take to charge that huge battery from the Zappi? Chee...

Re: Zappi EVSE

I too support Open Source where I can; I run various flavours of Linux on each of myPCs. The OpenEVSE looks the goods but I've not been able to find it from an Aus supplier. After some previous experience with imported electrical/electronic gear I'm wary of items that may not meet Australian Standar...

Zappi EVSE

The Zappi 7kW EVSE is apparently available for pre-order from evolutionaustralia.com.au priced at AU $1099. Expected to be available in limited quantities in early September. i am particularly interested in this product because it promises to be a neat means of charging an EV solely from Solar PV ge...

Re: Emergency spare wheel

Hi Dave, Thanks for the link. The discussion in that forum is quite interesting. It allays any concerns re: swapping wheels on the Zoe; and I can now tick that one off as 'problem solved'. Just for interest, I looked up the specs for the Renault Kangoo Z.E van. It has a kerb weight of 1585kg and the...

Re: Emergency spare wheel

Hi all, Getting back to my original post, bemoaning the lack of a spare wheel in the Zoe, can anyone confirm if the vehicle actually has recognizable jacking points? I have been looking through the Zoe Drivers' Handbook, downloadable from: http://myrenaultzoe.com/index.php/zoe-description/documents/...

Re: Emergency spare wheel

Hi David, my tyre repair kit is made up of bits and pieces gathered over several decades. I originally bought a small tyre repair kit in the 70s. I still have the wrapper cum instructions that came with it and can tell you that it was branded Victor and cost $13. It consisted of 1 rasp tool (reamer)...

Hi Mike, I think you've nailed it :lol: I forgot to add in my initial post that for a <4mm hole there's no way I would even consider using the supplied sealant. I too carry a plugging kit. It is fairly basic comprising of: a reamer, a threader , a couple of plugs and a tiny jar of vaseline. Together...

Re: Emergency spare wheel

Hi T1 Terry, I don't know if the new stuff is better, but in my old Cox ride-on mower the tyres came pretreated with something called Sheeld. In the blurb that came with the mower there was much hype about protection from punctures. Sure enough, the first time I had a puncture, the stuff fizzed out ...

Emergency spare wheel

The Renault Zoe, in common with many other 'modern' vehicles, does not come equipped with a spare wheel & tyre. I must admit, when I looked under the boot floor covering I was taken aback, to say the least. There it was: a little compressor gadget and a spray can. No wonder the boot capacity is so s...

Re: Zoe range vs temp & speed

Hi people, Thank you for providing some very useful information on this topic. Thank you Dave for the in-depth research in your last post. I am now definitely leaning towards the Zoe as the best answer to our urban transport needs. The battery thermal control is the clincher. I found this 7 part tec...

Re: Zoe range vs temp & speed

Hi Dave, You're not wrong about the dangers of 400Vdc, especailly coupled with the very high Amps available. I have had some fun plugging your table into a spread sheet and performing some simple calculations. What stands out is the reduction in range due to temperature differences for each constant...

Hi Dave, That's great table you produced from the simulator. It makes it so easy to understand how the range is affected by variations in sustained speed and ambient temperature. Iv'e copied it into my information file for the Zoe. I must tell my wife that, if we buy it, she should only drive the Zo...

Hi Once we had returned to the dealership (Sydney) from our test drive of the Zoe, the salesperson was very keen for us to put down a deposit. He explained that the vehicle had to be ordered and that it would take some weeks to delivery. In the meantime, he suggested we also order what he called the...

Re: Zoe on steep hills

Hi It's reassuring to see that the Zoe can easily negotiate quite steep driveways. I had my first test drive of a Zoe Intens last week from Sydney City Renault. It felt quite zippy but, because of the 60 kph limits in that area, I did not get the chance to try it at highway speeds. How does it perfo...
