Re: Inside an iMiEV's LEV50 cell

I second that. The equation has changed over time. Lithium-ion battery advances have made supercaps irrelevant. Indeedy, a while back I've calculated it. Even then supercap was irrelevant. Roughly speaking, for the same super-cap 1kWh energy addition , you can add 24kWh of lithium battery at the sa...

Put a mega-ohm resistor between 0V terminal and chassis? Will that violate any regulation?

Now can we see how far the diesel runs on sunshine?
My guess is 400-ish km. Sunshine --> Model X --> Diesel on Trailer.

Drag race it meanwhile you're at it. Please!

Re: Diesel generator + Tesla vs Diesel car

...They'd averaged 145 Wh/km even when driving at 110 km/h everywhere, so that 18 kWh wasn't used entirely. ... Ah, that's more like it. I didn't expect Tesla is that 'inefficient'. What I didn't expect, how efficient diesel genset is. Converting 4.4 litre of diesel (around 44kWh of contained energ...

Re: Diesel generator + Tesla vs Diesel car

I'm a bit lost. So 18kWh added to cover exactly the 104km distance? Was that pre-calculated so that the Tesla use 18kWh per 100km?

Battery warranty is 5 years or 100,000km from date of first sale.
That's good to know. I'm trying to find the written details on this one but to no avail. This means I have time until 2019! The first owner, which is not me, bought it in 2014.

Re: 2nd Hand LEAF

There's certainly a risk of getting bad batch. If you can somehow find out the history, from being driven from full to empty and still has 120 km or more, then you definitely have a good buy. Since the likelihood of Australian government opening up second hand EV like NZ is very unlikely, you don't ...

Re: 61 EV's charging simultaneously

"Gemtek director Florian Popp said the mass-charging drew more than half a megawatt from the grid."

Wow, that's 8kW per car. So, most Teslas on-site configured for high power?

I wonder what public comments on this event, "Oh, look, EV going to bring our grid down" :roll:

Re: Tesla PW2

The battery and the 5kW inverter is definitely built-in to the same enclosure (with the big a$$ Tesla logo on it). The 'Gateway' box, from what the installer told me (and also from Tesla's block diagram) contains a 'switch'. I'm guessing this is a remote controlled switch (controlled by the PW2) as ...

Re: Where to source electrical hardware

Good point, I've never seen such a high current rated relays (for AC circuit). Looks like you need to go the hard way, i.e. 2-off high current contactors (much easier to get) with modified control circuit (so that one contactor closes where the other opens).
