Re: Zoe range vs temp & speed

... Lowest est range we have ever seen after a full charge was 217km. That was after driving at 110kmh with hills. :o That's a really good confirmation that the size of the car doesn't affect much on efficiency when you travel at 110kph (yours roughly 0.18kWh/km). Makes me more impressed with Ioniq...

Re: EV BATTERY DISCUSSION AND SUGGESTIONS

That mass includes the charger, DC/DC converter, HV switch gear, cooling system and related control electronics. If you take that mass out of the system you have something closer to 200 Wh/kg. The 63 Ah cells from LG are Li-NMC, not titanate. Tesla's 2170 cell is indeed impressive. The cell itself ...

I've just found Model-3 pack density is merely 159.5Wh/kg. How on earth yours get that high, even with LTO? I thought LTO is much lower energy density?? I'm super impressed!! :o

Wow, you're definitely one of the lucky one to get i-Miev @15k 4 years ago. Depreciation is always the killer dwarfing everything else. I was so tempted to get i-Miev exactly 4 years ago as well from the dealer advertised at 14k. Too bad the 4-seat simply won't work for my family, so I got Leaf inst...

Re: Ultra fast chargers (350kW/HPC) in Victoria

I understand the logic of the spacing between fast chargers on major roads. When demand becomes higher , in the future, rather than double the number of chargers at these locations, wouldn't it be better to locate extra chargers in between? Echoing you here. I simply don't understand the current fi...

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...
