One of the key battery management strategies is actually MORE frequent charges such that the battery is kept within the middle of the pack as much as possible.

I charged my tesla 40-80% about 95% of the time over 15k miles every night and still lost 6% of battery capacity. Pretty well documented over millions of cars, and the unofficial or official stat is 12% loss after 200,000 miles.

“ChargeScape’s platform will give electric utilities access to EV battery energy across a wide pool of EVs….Additionally, by leveraging automaker telematics, ChargeScape intends to provide managed charge scheduling through vehicle connectivity without requiring Wi-Fi-enabled charging stations. This will support the many EV customers who do not use “smart” chargers at home, as their EVs would otherwise be unreachable for grid services.”

Can you interpret in plain English? My tesla uses smart off peak charging already. My friends in California use solar and power walls. So this is saying for those Honda and bmw etc owners who don’t have smart chargers at home this service will help utilities manage the load from …. Some EVs to other EVs? I did read this, and it makes no sense to me.

You are giving me your one anecdote which honestly sounds like complete nonsense. 6% degredation over 15,000 miles means you did something wrong. I have an Audi E Tron with 30,000 miles and just had the battery tested at 98% health.

And I think you are hurting your point citing the 12% degradation over 200,000 miles. How many vehicles engines run past 200,000 miles? If you have an EV that runs well at 200,000 miles (most will as they are relatively simple to operate) and has lost maybe 25-30 miles of range, who the hell cares?

Nah, it was a bit high at 20 miles lost, but then levels out. I had the model 3 perf and drove it hard. Not trying to argue just giving an anecdote. Feel free to disregard. Too bad your Audi gets such poor efficiency and range, but congrats on excellent battery health.

This is saying that for any EV that has Vehicle To Load (which is admittedly a small number at this point), they will be able to get paid to use their EV as a local powerplant which provides supplemental power to the grid at times of peak need. It is one significant solution in a slew of others (like your friends’ Powerwalls and solar panels) which will provide the redundant sources if energy that the grid will rely on. This will make for a more resilient grid, particularly as energy demands shift from consumer petroleum use to consumer electric use supplied by the grid.

Poor range, but charges at 140kw throughout the pack. Don’t believe your Tesla can say the same.

Oh and it doesn’t feel like I’m driving a tin can which is a plus. No offense to your Tesla. Too generic for my liking. I’ll still take my Polestar 2 over the M3P any day. Just as fast in the 30-90 range where it counts and far more premium with the nappa leather package. But hey, to each their own.

False!

It is written that way for a reason, because when you put in plain text...it isn't something people will sign up for. This is along the lines of the programs from utilities offering lower rates for allowing them remote access to your smart thermostat.

They essentially want you to sign an agreement for them to use your EV's battery pack as grid support. The best part is(sarcasm), they will "manage" it all for you. How about they manage deez nuts. Also if you read other articles, if you produce electricity via solar and have home storage. They will want access to that as well.

One of the most attractive things about going electric via solar/storage/EV's...is being off grid.

It might help in some cases but I don’t think this is the solution. The grid still needs the capacity for orders of magnitude more EV’s. I’m not saying there is no value. It’s just not nearly enough.

Yet another bullshit PR press release heavy on fluff and light on details.

I agree. This is not the end all be all, but another way to provide redundanct power supply. And honestly, this is one of the better solutions, because of the ability to dynamically share load across EVs connected to the grid. This is more of an energy/load-balancing optimization strategy than it is an energy generation strategy.

they need to get this going asap, I read yesterday Tesla has 50k stations out there that's insane. Curious to see how long this venture will take to get going and also to have enough stations out there to make a dent into teslas set up.

Also for all you investor experts out there, given this venture, anyone see any potential lanes for making some profit based off this? Obv there are going to be some companies making money off this huge venture, where do you see it and why?

[pegogetem]

Nice, it’ll compliment the rest of the EV charging networks!

[M3WC]

Did anyone even read the press release? This has nothing to with building charging stations.

They want your EV battery pack to help support their failing power grids.

In the UK, some utilities are already crediting customers who use electricity during periods of over-supply. The idea is that you heat your water tank, charge your EV, run the washing machine, or the dishwasher when renewables like wind produce more than the supply grid can consume or store. It displaces excess demand during peak periods like early evening. You get an email or text telling you that a credit slot is coming up inthe next couple of hours and if you can, run something that you’d otherwise use later.

It’s frustrating for an EV owner that they have an expensive battery built into their car, but if they have solar panels they have to buy another expensive battery to store their solar energy for later. Their obivous question is ‘Why can’t I use my car battery and then draw on it later for domestic appliances?’. Well, this would allow them to do exactly that.

For me, even without solar panels, I’d only have to charge up my car battery at the night cheap rate more often than I do at present, and I could then sell the stored energy back to the utility when they need it. A sort of arbitrage for the consumer. Obviously, it won’t work for every EV owner but then that’s why at present not everyone is on the night tariff that I use, where electricity is 20% of the day time price and when I obviously am going to charge my EV.

Even now, if I program my EV for a night time recharge and plug it in during the day, the utility provider sometimes charges it in the day - but at the night time discounted rate, just because it has a surplus. But this needs integration of the vehicle systems, the charge point and the utility provider’s software. At the moment, in the UK, this integration is only there for a subset of products and interestingly, Tesla doesn’t dominate this landscape.
