I suspect that over 90% of NZers would be fine on a 7kW home charger.

 

As batteries get bigger there is less & less need to hit 100%, charging to 70 or 80 percent will be easily enough for most people's commute - and they would still get home with comfortably enough power left to be able to go out for the evening.

 

With long trips the need to charger from near zero to a full 100% will almost never happen when driving a longer range car.  I could get from home to Cape Reinga or from home to Wellington in a Model 3 performance, with only a single stop to top up to 80%.  Basically I'd run out of North Island before the range was a problem.  Even a 100kW charger would be enough so long trips were no biggie.

 

My 24kWh Leaf would be rubbish on a long trip, but it does get me to work & back (70km total for the round trip) at a low cost and with great reliability.

 

 

Oh yeah, the whole spiel some people get into about needing to do Auckland to Wellington without stopping is such a niche scenario. A lot of people never do that and if they do it's maybe once or twice a year - those that do it regularly is a very small number. 

 

The trip I recently did in my Long Range Performance put to bed any issues I had with range. I started off from staying in the lower Tararua area with a charge of 70%. To get back to Auckland the car wanted to make a 20min stop at the Taupo supercharger and then we arrived home with 15% left - that was with the AC working hard to keep the cabin at 19c as we drove through the Hawkes Bay with an outside temp of 30c. The car was back to 80% overnight at home.

I'm not looking to get a full EV vehicle. I am however planning to get a Prius Plug-in Hybrid early 2020. For my use the 8.8kWh--- with an EV Range of approximately 63km --- it will be more than enough to get me to town and back... more than a few times a day (if needed). Will even get me to the golf course and back. I could go a couple of or few months before needing to put any petrol in it.

I'm still using an 8amp charger for my model 3, easily tops up my commute every 2-4 days and makes sure i have plenty of charge for a weekend.

 

 

 

As for plug in hybrid they can work well, just needs the petrol to be kept fresh every 3-4 months so you do end up using some regardless.  Hybrid batteries are hit harder than full EV typically- deeper discharge more frequently.

Long 42 minute video. Something to listen to. Just two talking heads.

This looks encouraging.  Obviously a long way to go to commercialisation but still look promising at this early stage and encouraging to see the reference to low production cost

Nice. Was it IBM that had some other new idea recently reported? If these innovators can reinvent batter tech that is massive for EV range and probably cost as well, the current barriers.

Sulfur batteries have been around a while, more energy/power but more expensive ( factor of 8 or so last I looked) not sure about longevity. 

 

So much new battery tech has drawbacks that need to be overcome, cycles, temp ranges, cost etc, li-ion will be replaced one day in the next few years I expect though.

Well the final result for 2019 registrations are now up,

 

https://www.transport.govt.nz/mot-resources/vehicle-fleet-statistics/monthly-electric-and-hybrid-light-vehicle-registrations-2/

 

Interesting points:

 

We have reached "Peak leaf" - 2019 imports of used leafs were lower than 2018,

 

Subsequently total overall registrations of used EVs has also peaked and actually declined in 2019 vs 2018 (3500 vs 3600)

 

Overall Total EV regs are continuing to grow,(albeit more slowly)  (7000 vs 5500)  but this is being driven by new EVs with over 650 Model 3s  arriving in the 4th quarter..

Sadly with the potential 2021 freebate system coming in 2020 might be slower yet :/

 

 

 

Europe will suck in all the EVs they can sell, leaving us with used leaf, tesla and the high end SUVs that no one else wants.

It's good that NZ-new EVs are driving the growth - these will be available second hand in a few years time.  There are some nice new EV options our there now if you have the ping.

With a 2,500 levy on a ute and 8,000 rebate on a EV mooted by Shaw, for the policy to be cost neutral he would be expecting three times as many oil burners as EVs.

Given that the ratio of SUV:EV purchases are at 64:1 as of the last count (can't find the article anymore, alas, so no source to back me up right now), I think it'll be alright.

As above, 3:1 ratio would be rather good...

Interestingly, according to those stats, PHEV annual mileage is only around 8% higher than BEV annual mileage. This suggests that the longer range of a PHEV (being the main reason to choose one over a BEV) is not really being taken advantage of in a big way.

I ran an Outlander PHEV for a couple years, you are not generally keen to use it on petrol tbh, its not bad but you get used to not filling it with expensive smelly liquids. its like burning cash
