Random EV thoughts.....

liamog · 30-03-2022 01:24PM

Given their is no tailpipe, and the vehicle itself is not emitting, I think it's fair to call it a zero emission vehicle.

This is actually something I was thinking would be great for emergency vehicles and vehicles that have to work in remote areas

It would be fairly simple to build an EV and then bolt on a generator to charge the battery. Again the i3 is the perfect example

I've seen generator modules that fit under a truck which could be an option. They don't need to be particularly powerful, the idea being that they try to keep the battery above a certain threshold. While the vehicle is cruising the battery is charged but if it needs to accelerate then it can dip into it's battery reserve

You could even make a modular system so you could easily swap out a diesel generator for something like a fuel cell or more batteries down the line depending on the need

Again to stress, I think it's only really worthwhile for specialist applications. As we're seeing most normal haulage jobs can be handled on battery power alone

ID cars can only do DC bidirectional charging at the moment. Well actually they can't do any V2G at the moment but they have the hardware for DC V2G already. Software to unlock it is supposed to be out end of 2022, apparently they're waiting on the updated CCS2 spec before rolling it out

I'd much prefer if VW did AC V2L like Ford, MG and Kia/Hyundai. It's definitely the way the market is going and seems much simpler in implementation because you don't need to worry as much about grid integration

Speaking of which, Deiss mentioned that the biggest hurdle with V2G wasn't technology but regulatory, since they have to customise the solution for every country just about. I could very easily see VW looking at Ireland's ridiculous set of rules and just not bothering 😬

DC bi-directional charging is no good. First of all there is not yet even any standard for CCS bi-directional charging. And DC chargers in the home will always be expensive and there is totally no need for it. AC at up to 22kW (if your house is 3 phase) or 7kW (if your house is 1 phase) is adequate. I can't see how there are any regulatory issues with AC either, it's working the same way as if you have a home attached power wall.

wassie · 30-03-2022 03:55PM

Ford have a released a bi-directional AC charging solution in the US for the F-150 Lightning EV. Make sense given its battery size for the extended range (131kWh).

https://electrek.co/2022/03/01/ford-launches-bi-directional-home-charging-station-surprisingly-good-price/

The new Quasar 2 Wallbox also recently released (again in the US) a DC charger that has a CCS Combo plug charging at 7.4kW/32A or 11.5kW/48A. Im not aware of any supported vehicles at the moment. And I would expect it to be pricey.

Will be interesting to see where this convergence of technologies heads in the long term.

unkel · 30-03-2022 04:10PM

$1310 plus install costs for Ford's bi-directional 10kW home charge point is reasonable enough, I'd gladly pay that if my car(s) had bi-directional charging enabled

Based on the Quasar 1, I'd be expecting a price of around €5k, pretty pricey

I agree with @unkel that AC V2G is better for domestic scenarios, much cheaper installation costs and you have the advantage that the inverter is in your car, so you've a portable power pack anywhere your car goes

DC V2G is really suited to big commercial fleets which can make a lot of money exporting to the grid. The main advantage of DC is that in theory you can discharge as fast as the car can charge, so 150kW should be possible with the right equipment

If you had a fleet of trucks plugged into chargers every evening you could export several MW of power at once, assuming you had a suitable inverter. This is the kind of scale that Eirgrid would be more interested in rather than a bunch of domestic customers exporting a few kilowatts whenever they feel like it

@the_amazing_raisin "This is the kind of scale that Eirgrid would be more interested in rather than a bunch of domestic customers exporting a few kilowatts whenever they feel like it"

You'd be surprised. I recently saw some figures for domestic micro PV generation in the Netherlands on a bright day in winter and it is one of the major components of electricity production now. There is a lot of power in small installs once they run into big numbers. And PV over there works less well than PV in Ireland. Many houses in Ireland could generate their entire yearly electricity consumption (or more) from 12-16 panels on the roof

Absolutely, my folks put in 5-6kw array in November and have generated more than they've used since, which is pretty amazing over the winter. No EV or heat pump yet though

Can't imagine how much they'll be ahead by next winter. They're hanging onto the backwards spinning meter for dear life🤣

True but the Netherlands also has a sane government and regulators that seem to have customers interests at heart

Whereas we got a herd of cats in the Dail and the Chicago Boys for regulators

If there was massive uptake, the issue would be the network. Our 20th century one-way grid is expected to be all things to all customers, but it simply wasn’t built to accomodate large amounts of two-way power flows. Australia's been having problems with this for a few years now in parts due to extensive PV uptake. Thats why I find the concept of a utilising car battery for home generation interesting as it nudges you in the direction towards self sufficiency.

unkel · 31-03-2022 11:40AM

Yes indeed @wassie - V2G / V2H is the holy grail here. Maximise self utilisation in the home or business over any short periods (within a day or up to a few days) and not just stabilise the grid but be a massive buffer for when we overproduce renewables (wind and solar)

So THAT'S what Toyota were talking about when they say self-charging ... :P

Redfox25 · 31-03-2022 07:23PM

Its pretty impressive, if only they could harness the excess energy

At least they weren't cheating on the emissions tests this time. Or just haven't been caught yet

A German court rules that running charging cables across the public sidewalk is not allowed, even when if using a special cable protector.

NIMAN · 31-03-2022 10:10PM

Don't forget the time change last week, in case anyone out there is charging for an hour on the day rate instead of the night rate.

wassie · 31-03-2022 10:57PM

Big headline - but not a big issue. There are no reports of cars actually catching fire - only 16 cases of damage.

https://car-recalls.eu/vw-audi-skoda-seat-engine-cover-fire/

Due to current production capacity constraints, replacing the cover with a new one is not possible. Therefore, the cover will only be removed during the first service visit in a few minutes. A second service visit will be required to retrofit it as soon as the authorised partner delivers the modified cover

Anyone have any experience of the AC chargers at Titanic Belfast? Apparently there's 2 free to use ones in the underground parking, I'm guessing 7kW or so

Thinking of heading up and a destination charger for a couple of hours would remove any fast charging along the way (and any encounters with Ecars NI ideally)
