Stick to spreading credible stories to express your dislike of renewables/ev.
I read on socials that someone brought the Exxon Valdez and said theyd never need to buy fuel again !
Dunno if its possible or where theyd park it but it was funny as all hell !
:/

Curious, Could you pull out your camping solar panels cells and charge you EV, or charge a spare battery and use that to charge your EV?
Wouldn't be able to provide the same amount of oomph as your wall sockets for sure, but could get you out of trouble?

I find it difficult to believe that any ev could run down to 0% thats what their BMS are designed to prevent.

This is 100% true, but it'll cut off the battery long before you get anywhere near completely flat. Like power tools most are designed to only go down to something like 15% capacity before they shut off.

If you can't start the car, does it really matter how much is left in the battery?

In that case its a bit like an ice that runs out of petrol then isnt it ?

As far as I know it doesn't work like that, EV batteries are massive arrays of smaller cells, to charge them you need quite high DC voltages, not something that comes from your typical small SolarPV or lead acid battery. Probably a portable inverter / generator might get you started, which is a tad ironic.


It does make you wonder though what is the RACV equivalent of road side assist for an EV, maybe you can use one EV to partially charge another. I think many EVs like a Landcruiser come with a built in low power inverter. I gather the missus won't have a spare of that cable in her purse?

As i have stated previously that I'm not an ev owner but my understanding is that "fast chargers" use DC and most home chargers use AC.
I'd imagine that pending suitable connections you could top up an ev using camping solar panels or another battery, but how much could they put in over what timeframe ?
There are Lithium battery packs the size of small gensets that are used in camping situations where you'd connect them to solar and/or your car alternator when driving (anderson plug) possibly pending connections one COULD be used to move an ev a short distance, maybe...
Think of it as a 5lt gerrycan, it aint much but its more than you've got now...

Ive never heard of anyone leaving their ev sitting around on such a low charge, it would defy logic, even yours !
Let alone the reality that your ev is capable of being your house battery, charging off your home solar during the day and feeding back into your home by night... or when mains power is lost.

A 12v $60 Jump Starter will start your EV but you cant charge the battery with them, a Jackery or Bluetti type powerstation at the top end might be able to supply 1800-2000watts which could give you 10-12 kilometres worth of juice but thats going to set you back $3-4K.
You can use your EV to power your home, you need a bidirectional charger so you can convert DC back to AC for your home.....I believe but dont quote me that a couple of the present Mitsubishi's one being the Outlander PHEV can be configured for BiDirectional charging. Id expect it to become the norm across all EVs as well as being able to power appliances directly.
Think I read that a EV from Nissan was trialled in Japan and powered a house for 4 days.....

As i have stated previously that I'm not an ev owner but my understanding is that "fast chargers" use DC and most home chargers use AC.

All batteries are charged with DC, whether the charge circuit converts DC to DC or AC to DC makes no difference, most EV cars have smart sockets for both AC or DC charging. DC can mean CW(Constant Wattage, Constant Current, Constant Voltage) or Pulsed dependant on the charger design, but it's all DC. Some modulate power by varying voltage, others use PWM(Pulse Width Modulation.)

If you have a 12v / 240v inverter, you can use a 12v source like a lead acid battery to charge your EV enough to get it to a charge station. You could use jumper cables to run an inverter off the idling petrol or diesel vehicle, and the outback charge stations are often just diesel generators which have an integrated 240v inverter, coin or credit card operated of course.

Most portable SolarPV won't have anywhere near the power to give any useful range via an inverter, at least not in a single day of charging, it would be like trying to warm your bath water with a candle. The best rooftop SolarPV panels are much more efficient than the portables and yet roof top panels typically only deliver a few hundred watts each day, I think the very best make it to about 650 Watts on a perfect conditions. Good portable panels are about 50% of the solid roof top variety. Your EV battery and motors are measured in tens of Kilowatts, I think a low end Tesla is in the order of 60 ~ 70Kw!

An interesting point, it you bolted a solid SolarPV to the roof of your Tesla in a weird attempt to extend the range, you would actually lose range, because the weight and drag of the panel more than offsets the energy it creates.

Yeah, it all comes down to battery capacity and load.
I've spoken to guys with tesla powerwalls (20Kwh ?) and plugging in their 70odd Kwh cars and lasting 3-4 days.
The bottom line is its all doable with some planning on your part and the gov.

Speaking of governments role, I also believe that the NT still has 3 large scale solar arrays that have been completed for 2+ years but our electricity distributor hasnt ticked them off to allow them to connect to the grid !
Sitting there idle.

I've spoken to guy overseas who has just handed back his electricity meter because for the past 2 years (I've seen pics of his bills) his consumption charge was $0 per month.
He was happy to pay the daily charge to have mains  backup but got constant grief in the form of various random inspections because they didnt believe he was using no power.

The NT was/is always a bit of a mess with solar, think an Italian conglomerate own a few of the facilities and the system up there has too many cooks in the kitchen. They wont connect those solar facilities to the grid because of storage battery issues and a fear the ageing infrastructure will fall over plus when you connect a lot of solar arrays at once you get poorer regulation which means dirty power which spikes the line up to very high voltages which kills older infrastructure so they switch those feeds off.
They will probably need to get a 3rd party Engineering Consultant company in to test and sign off on the system because thats how it usually works and they dont come cheap.
NT Government give good rebates on EV vehicles dont they?
