Re: Prelude conversion project - some questions

We can put a heat exchanger on the battery coolant line so that refrigerant can be used directly to cool the battery pack. I'm inclined to think that a fan-forced radiator to ambient will suffice, but we do get some unpleasantly hot days through summer in Perth. Shouldn't be too hard to plumb in if...

Re: Prelude conversion project - some questions

Nice one! Any fancy charging capability? I presume planned for basic J1772, or straight to Mennekes 22kW? :) What's the plan for air-con? I wonder any products out there these days for EV converts to do variable power air-con (instead of full ON-OFF)? That's what I've found very good with OEM EV (es...

Wow, at that price, which includes the charger, definitely compete with basic EV charger! Way worth it. Unless, some people (like myself) love batteries too much and collect more debt by getting PW2. :lol:

Re: Arvio 3.5kWh drop-in-battery-replacement supercapacitor on sale

Hi Supercaps, can you please list your supercap 'cells' (i.e. the capacitor itself) in your store? I wanted to buy the supercap itself, but alas, not listed in your store. You have the module for AUD4,260 currently, but I believe you'll sell more of them if you list the 'cells' itself. At AUD1.20/Wh...

Re: powerwalls

What about SonnenFlat deal? Are you eligible (i.e. not with Ergon in QLD)?

I looked this up after installing my PW2 in WA. If I were eligible, I would definitely go with SonnenFlat, purely because it's more financially makes sense. In WA, the ROI is not yet there to buy PW2.

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...

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.

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 ...

The battery and the 5kW inverter is definitely built-in to the same enclosure (with the big a$$ Tesla logo on it).
