Re: Total Cost of Ownership - ICE and EV

Hi Kim, If you don't need to travel long distance (a.k.a. city dweller only), then the imported version of 2nd hand Leaf will be perfect for you. Depreciation is definitely the biggest cost, dwarfing the fuel and maintenance cost. So, minimising depreciation is the key. Make sure you'll get the Niss...

Re: Assembling a team to develop an EV platform in Brisbane

You make me wonder what's going on with those in Evans Motor team. I was so bloody certain back then (maybe as far as early 2010-ish?) that these guys will take over the world. 8-)

Re: Heating and Range in Electric Vehicle Survey

Huh, must be composed by those researchers live in Melbourne or Tassie. So irrelevant for other users in Oz. Ability not to worry that one's battery degrade due to heat (instead of heating internal cabin issue) is the bees knees for Oz.

Thanks for sharing the progress. You really should run the Battery Test Centre technical team. Some of the results are riddled with technical issues (due to difficulties interfacing with BMS, whether OEM or non-OEM) :x

Yup, I've been watching Carnegie since its early inception. But cost is just simply too much playing in a harsh environment. Impossible to compete with cheaper solar and wind.

Indeedy. I'm very interested to see whether DC microgrid will come into play due to this reason as well. Even Siemens already mentioning MVDC network for AEMO. Why not even go further down to LV network?

Re: How DC chargers work

Hi Brendon, 150kW is not hard to get (although not trivial). From Tritium user manual (albeit, 100kW station only), it recommends 50mm2 cable (150A feed). Bunch of no-gooders broke the world record in Kwinana sometime ago , requiring 800A feed (half Mega-Watt). Too bad, I can't find the detailed inf...

Re: Nissan Leaf Battery Flattening Test

My dealer didn't give that advise.

Although I did notice my SoH increased very, very slightly (around 1%) when I did test to flat, but it quickly revert to normal. See the spike in Feb early this year on mine (ignore other spikes):

Re: The full Hyundai Ioniq range headed down under

Yes but the Ioniq is also very efficient, so that 28 kWh will get you almost 200 km. Still a bit short, but definitely better range than a 2012 Leaf. The Ioniq is definitely in my watch list. I rarely go out of the city, so smaller battery (hence cheaper) makes sense. Fast charger network is far mo...
