gzt: I'm considering an MG Excite 51. What does it cost to insure something like that?

I have an Excite64.

Insurance is $84.47/month (1013.64 pa). It would be less than that if I paid in one lump sum (like mid-$900s I think).

That's with AA. I asked a question in another post, people mentioned in that one, that FMG does some good deals as well.

Note I'm not anti-EV. I know petrol explosion are so common, that they are not newsworthy.

Firefighters do need training and education around handling EV's fires.

His references to the first two incidents being PHEVs but then not defining the following cases in terms of "electric vehicle" vs. hybrid raises more questions than answers.

Add the presence of flammable fossil fuels to a malfunctioning large capacity electric battery and things don't end well but to lay the blame at the foot of EVs is misleading at best and seems like just more FUD from the anti-EV movement.

EV's may not catch fire more often but when they do the fire is very much harder to extinguish and as a result have the potential to cause significantly more damage. Current fire suppression standards in places like parking buildings car ferries etc are totally inadequate for EV fires. Also I think you'll find Fire Brigades are not adequately equipped to fight EV fires in confined spaces like parking buildings.

These are facts not anti EV hype.

I popped in to the take charge expo in Christchurch this morning and really interesting how many more vehicles they had on display compared to last year. They were set up in the same hall as last year and had a lot more variety with some nice stuff being shown off including a few cars not released yet Like the vyd seal. Felt a bit like last chance saloon for the rebate with the salesmen suggesting you need to get a deposit down asap to make sure you are driving away with the rebate.

One car that got me was the ora, I've not been a fan of the styling but the thing isn't as fugly in person as the photos make it look, also super cheap with them available at $35k with the rebate. A bit too small for our needs if we choo in the leaf but at that price it's a tempting commuter car that we never put the kids in.

Do MGs have a feature to cap charge rate? I'd feel better about plugging in some marginal power scenarios if I could reduce to 1200 2000 watt max or something like that. I realise that is a very low rate of charge. That's fine for rare occasions when it's needed.

Haven't seen one on our ZS (although to be fair my wife drives it far more often than me). I use the limiter in the Wallbox instead.

I think mine does (MG4).

In the charging screen (not on the App) there is something about charge rate. Sorry, never needed to lower the charge rate, so don't know if it is what you're after. I'll take a look next time I'm in the car.

Just remember that if you drop it really low then you are really losing efficiency as so much of the car is on regardless of the charge rate. That is why the US with their toy-like voltage really struggle to charge things up without a proper 240v charger.

Well according to this guy the US has 240V in the household

Not if the batteries are LFP chemistry.

Just like we have 400 volts here with 3 phase power.

MG vehicles with LFP batteries (standard range) don't have a limit control in the charging app, you can't set them to stop charging at 80% or similar. The long range versions have LNMC chemistry which doesn't take kindly to regular 100% charging so the app allows a limit to be set.

For those who want don't want to watch the video

Typical USA households have 240v service, essentially 2 phases, 180 degrees out of phase with a center tap.

For small loads, you take a power between a phase an the center tap, and get 120v.

For big loads (clothes dryers, large air conditioners etc), they take their power between the two phases (which appears to the load as a single phase).

The example house has a 200Amp feed (at 240V), which is a heap more power than my house in NZ (im not sure, but it is easy 63A or 80A at 230v)

Issue in the USA is that the regular outlets are somewhat puny for high loads like charging an EV, so the charge rates will be really slow. In NZ our regular outlets are better. But we don't have the option of plugging into a dryer socket which in the US as typically rated for 30A, 240v.

Of course no issue in either country if you get a sparky out to install a hardwired EVSE.

Going back to the topic, some EV's can turn down their charge speed (my BMW had three steps), some cannot (i.e. my Nissan leaf).

Some EVSE's can turn down charge rate (mine can do 6A or 8A).

Note most EV's have a minimum charge speed, so you would want to test if you want less than 6A.

And as per the other comment, EV's charging efficiency goes down at very slow charge rates. Essentially the overhead makes up a bigger portion. Also if you want to charge your EV exclusively at 6A, your cooling pump is going to see a lot of running hours.
