The rate of charge beyond 80% of the battery's capacity slows dramatically in all EVs so charging to 100% is best avoided because you occupy the charger for far longer than is optimum, it is potentially damaging to the battery chemistry to charge to 100% (as is depleting it to below 10%) and of course it means you will spend longer waiting for your vehicle to charge. It is more usual to part charge between 20% & 80% as charging is available to avoid the above issues and save time overall. Also some chargers will impose a time charge if the charging rate is too low to discourage unnecessary occupying of their facilities though this doesn't seem to have been the case here.(22-01-2024, 11:00 AM)harm_less Wrote: So it appears you've been sucking up the EV FUD that is so prevalent currently. And I'm guessing you're still relying on fossil fuel for your vehicle's energy.
Yes EVs require minerals and hydrocarbons in their manufacture but unlike ICEVs they continue consuming mineral resources during their everyday use. The minerals contained in an EV remain as a recyclable resource unlike the fuel burnt by ICEs that is only ever going to be a single use product, with the emissions ending up in our atmosphere. In New Zealand the source of the electricity used to recharge EVs comes from a grid that is made up of >80% renewables so our country is a perfect use case for EVs as the distances we travel are comparatively small (i.e. within EV battery range) and carbon neutrality for EVs is reached in less than 20,000km. Long distance ourneys are exactly where EVs shine as their running costs are less than for ICEVs and the more they are used the greater the positive benefit of their lower emissions.
So far as your Australian example is concerned Melbourne to Sydney is a 9 hour/900km journey. Firstly this is a brave call for the BMW 7 series with a 74L fuel tank and claimed 7.9L/100km fuel consumption. Also did the BMW driver require a picnic hamper and piss bottles to be able to drive that distance without having to also stop? Not enough detail in your story to support the calculations involved in the $17 but even when RUCs are introduced in April our Polestar2 will still be less expensive to 'fuel' than the fuel costs of an equivalent ICEV even with the more expensive electricity costs of public charging, and Australia don't charge EVs any RUCs.
If you're going to start regurgitating EV criticisms you might want to find reliable sources than you have here or you will be shot down.
Did you read what I posted? I commented that NZ is lucky re renewable- however most other countries- especially those with larger EV fleets rely predominately on gas, oil and coal for electrical generation.
Don't believe me on the test - watch it yourself

And I didn't say the ICE driver didn't stop - he stopped along with the EV driver. But the cost was still cheaper using the ICE car for this example. Sure if you only charge at home it will be cheaper than public networks but for a long trip? You have to use the public network.
Polstar2s are nice cars - and just watched a review on the 2024 where he drove Auckland to Wellington with a single stop in Levin. But it's a $94k car. A similar size would be say a Mazda CX 5. Top of the line is about $66k. $28000 buys an awful lot of gas.
The BMW 7i is a fairly high consumption EV at ~22kWh/100km but as it was put side by side with an equivalent BWW ICE model that's understandable. On that subject our Polestar2 (MY2022) consumes ~18kWh/100km.
The inexperience of the driver in respect to EVs is also made clear when he is commenting about the energy consumption of the likes of windscreen wipers. Pretty much anything on the 12V circuitry of an EV is infinitesimally low in regard to its effect on the high voltage main battery. This inexperience also raises the question of how well he minimised his electricity usage. One pedal driving engaged? (Where the car can be driven with just the throttle pedal which inititates regenerative braking on lifting the throttle). Also the guy driving the ICEV was treating the journey as an economy trial whereas the EV driver just didn't have the skills to do so.
I also note that the public charging rates were stated (65c x2, and 69c/kWh) whereas the only petrol price provided was if you noted that displayed on the pump ($2.09.9/L). Public charging rates are at similar prices to NZ but the petrol price is considerably cheaper.
So far as where you charge is concerned we tend towards plugging in at our host's when visiting out of province. Domestic power plans are usually <1/3 of public charging rates and we shout our hosts out to a meal during our stay so a win-win situation as still cheaper than using public charging for us. I expect this practice to become increasingly common as EVs become more mainstream and owners install wall chargers for their own EV's use. At that stage an offer to 'plug in' will become as common as serving visitors a coffee or a beer is now.
