Random EV thoughts.....

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

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).

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.

CCS Denial of Service attacks, don't think I've seen anything like this reported before.

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

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🤣

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.

Pah, I see you a puny 46te dump truck and raise you a 34,000te train!

(All glorified roller-coasters of course!)

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

Call you bluff (is the same link:))

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

I think they're actually only 3kW or so, unless they've been upgraded since I was last there.

They're on the left side just after the entrance to the underground park.

Ouch, 3kW, back to Leaf charging speeds

I'm hoping the fact that the parking is paid will mean the chargers are less likely to be blocked
