Batman: Nissan Leaf

Used ??  Bet the price of them just went up 20% with this announcement.

As an EV owner, the second impediment I hear after “the cost”, is always to do with charging. Not fast enough, not enough chargers, not enough range, etc.

 

Hence my disappointment. Just “get more EVs” and “here’s money” doesn’t address the infrastructure side of things. Where is the coordination for a network of high speed chargers? How about supporting the grid with home generation (ie PV panels) of some of the energy needed to power all these new vehicles? At the same time as encouraging charging at home, local bodies no longer require any sort of parking, let alone parking with access to a charger.

 

So because I live in the upper North Island I’ll continue to run my car on imported Indonesian coal and hope the 5 EVs in the neighbourhood don’t blow the transformer at the end of the street.

 

The government already has an extensive program for funding EV chargers. Here is a high level map of chargers the government has helped fund (here is a spreadsheet of everything). Do you want the government to instead create its own EV charging network?

You're also being a bit dramatic with a statement like "continuing to run your car on imported Indonesian coal". The grid is predominantly renewable with Huntly only capable of providing a very small percentage of the grid capacity. Furthermore, that Coal output is really only in use during heavy on peak periods - not when most people are charging their EV (unless you like paying higher electricity rates)

You'll likely pop your pole fuse before the street browns out.....

Trickle charging on a regular 10 amp outlet is no worse than running a heater....  Even at 7KW you are still pulling about the same as your Electric Range is rated at...

But 5 households that run 60 amps each on the same phase plus all the ‘normal’ houses will put a strain on it. The loads at our house when used concurrently with a 7kW wallbox will require management to stay under 60A.

The Indonesian coal comment is exaggeration for effect. I’m fully aware of NZ’s mix of Coal and Gas, renewables and unreliables for electricity.

HarmLessSolutions:The solution would be to incentivise EV charging during off peak by way of reduced tariffs to level out the load. Nothing like a financial carrot to modify people's behaviour.

 

As already happens on some tariffs.

The other option is some form of “ripple control” as per hot water.

I just have little faith there is a ‘plan’.

We use an 8A and I think we need to upgrade to something else. I'm toying with asking a sparky to go a back to back EO in the garage and a 15A caravan socket outside so we can see about charging 2 cars overnight. Once you go to 30kw the 8A takes a bit too long to be able to charge in the cheap power window and any higher the problem will only be worse.

I'm only thinking 7kw to future proof, if I'm paying for the install one day we'll have a 50kw+ car and the slower chargers just won't cut it anymore. So having both means was could keep a leaf as a commuter car and have the bigger one be our primary vehicle. I have asked EVs enhanced if they plan to address this with the 16 blade as charging their long range pack when it comes available on a 3.3kw plug will take forever. They said you can bolt on a eu charger easily or brought up using your ev to power your home as that uses DC, doesn't really help though and I'd hope they might be able to source some transformers to include with their big battery swap out.

Public AC charging we use if it's there and we are running on the low side but realistically could live without most of the time. I think people forget you can start each day with the full range and you don't need to detour to petrol stations anymore so it's actually easier to run. Fast charging we have only used a handful of times, our local warehouse has a free one that we only use because it's free and nearby, and other than that we did a Christchurch to tekapo trip and used them on that.

Pretty much every electric car in NZ except the older Zoe (which cannot DC charge) can already charge at or close to 50 kW. It's really not that quick when compared to current models charging at 150-350 kW

Sorry I meant battery capacity not charging speed. Those 15A plugs will hit 3.6kw so fine for 24-30kw packs, but will take 14 hours for a full 50kw charge. It will just take too long to do it in the time window. 36kw is the most I could achieve between 9pm-7am which would usually be enough for most days, it's just if we want to go further it will cost more and mean charging when power use on the grid is at it's peak.

For now no matter what I do I'm hampered by the leafs 3.3kw in board charger, the 7kw option was mainly if we were to buy a car with a bigger battery to facilitate getting it charged overnight before the peak timings kick in.

Unit police.

If you want to describe a capacity or quantity of energy, you need to use an appropriate unit like kWh (or if you want to run SI units joule).

The kW (1000 Watts) is a unit of power. 1 Watt = 1 Joule per second.

Using units incorrectly is leading to confusion.

Exactly this.

@everettpsycho Please use the correct units. Do you mean a 50 kWh battery?
