Comment Re:Old joke, bad business practice (Score 1) 22

I come up with some of my best engineering ideas while in the shower. I don't know why that is, but it happens to be a fact. No, I would not allow my employer to track me in there, at least not for any reasonable compensation (an unreasonable ask example would be to give me a billion dollars per second of footage - I'd be all in for that, may even be willing to negotiate a lower fee).

Comment "as a parent, as much as a Prime Minister" (Score 2) 147

I get his confusion, he is a parent and he represents the government. However those are supposed to be two separate functions, unless people want a paternalistic government which always knows best and is never wrong (like North Korea). Perhaps communism would work great in UK, everyone works to the best of their ability, gives all their earnings (100% tax) to the government, which will in turn dole out allowances according to each person's needs, enforce curfews, feed them only foods best for them (and their productivity), etc.

Comment Would same hold true when steering vehicles? (Score 1) 156

I've always found I felt more comfortably in control drifting a bike through a turn, or a car, when turning left. Same for turning on skis or skates. I could never explain why. I thought for a car it might be because the steering wheel is on the left where I drive and I somehow like being in the inside of the turn, but tried it once with RHD car, same left turn preference held. I can turn in either direction, but one just seems more comfortable.

Comment Maybe try a truly open system in EU? (Score 1) 75

Allow all apps access to all information on the phone, personal or not (same level of access as native iOS), also allow all submitted apps into the playstore for EU without any verification by Apple since that's just unfair censorship - EU obviously trusts that customers know best, perhaps customers will know to trust a list of "good" apps from their trusted source of information and will never download any app that might be bad for them. This would fully level the playing field and open it for true competition, right? Should any app prove to be ransomware or leaking PII, EU government will deal with the makers of the app directly. Of course, still allow users to control access for individual apps, the same granularity as controlling access from Siri or other iOS components (so if you cannot deny iOS apps to have access, you cannot deny the same access from 3rd party, gotta be fair). I'd like to see the results of such experiment, as long as it's not running on my phone of course.

It's most likely the case here. Some jurisdictions mandate real-time blurring (prior to storing in non-volatile storage), or blurring before the data leaves the vehicle (must blur before data transferred out of the car, or storage device removed from the car). Once a company has such a solution developed, might as well use it everywhere.

For rural just install Level 2 home charging, will give you 200-500 miles of range every day charged overnight depending on which EV you buy, and at a fraction of a cost of gas (think 3-5 miles per kWh, so if your kWh is $0.15, that's $0.05 per mile or less). People who have home charging don't need any fast charging near their homes, so even the one 20 miles away you will likely never use. I've been driving EV's for well over a decade, only charge outside of the house while road-tripping, and have done coast-to-coast in different EVs multiple times without any issues. My wife has charged outside the home maybe 5 times in the last 10 years she'd been driving it (she doesn't drive more than 300 miles a day), the closest one to home was 60 miles away.

Granted, if I was load balancing 9.6kW between all cars vs 19.2kW between all cars, yes, the peak load is different so grid might care (my grid doesn't, mostly hydro-electric, with some nuclear IIRC, they won't even offer a discounted rate in the evenings). However, before I upgraded to 19.2kW, I run ran two separate EVSEs 9.6kW and 11kW (non-load balancing EVSEs), so the peak load was actually a little higher, though maybe for shorter amount of time (only during the overlap when both cars charged).

As for modular DC on-board-chargers, only Tesla did that, and even they haven't done it in about a decade (2015 Model S still had 1 40A or 2x40A charger, 2016 Model S had a single 48A or a single 72A charger - same physical size, just some more components populated inside). AFAIK nobody does this stackable EV on-board-chargers today.

I hope you're right about the costs of DC chargers and installation. When the time comes and my car's warranty rejects replacing the 19.2kW charger with 9.6kW one, I hope they offer replacing my 3 load balancing EVSE's with 3 19.2kW load balancing DC chargers. I don't have solar, so they just have to load balance between each other.

Since you seem to know about this a lot, care to post a link to a reputable 20kW DC charger which can load balance with 2 others?

My 3 19.2kW EVSEs load balance together, so the total draw on the grid is never over 19.2kW. When 2 cars are charging, each is only allowed 9.6kW. When I need faster charging, I just unplug all but the EV that needs to charge faster (or make sure the other ones are not charging via a phone app). The grid doesn't care if I charge 2 EV's at 9.6kW each, or 1 EV at 19.2kW.

The argument on the weight is just silly. The on-board-charger is the exact same size and the weight is listed the same between the 2 parts, I suspect the sizing up of the MOSFET transistors, or maybe adding a couple, doesn't add any significant weight. I'd be willing to bet that you can't tell the difference between the 11kW and 22kW versions by just weighing them, especially if you just took it out of a live system so it may have some liquid coolant in it left.

Offering to replace my 3 AC EVSE's with set of load balancing HVDC chargers, installed, it not going to be $3K. $3K is a cheap Chinese hardware only. Higher quality 20kW HVDC run $10K+. I say replace all 3 plugs because the car is connected to different plugs at different times, but even if I was to agree to just one, it will not load balance with the other AV EVSE's. That said, for my specific usecase, replacing the AC EVSEs with 20kW DC chargers would be acceptable, since 19.2kW on-board-charger is primarily useful for me at home (there is one place outside of the house where I used to charge at 208V/80A, so 16.6kW where I'd be reduced to half of that, but there is a new HVDC charger now available nearby I prefer to use anyways as its way faster). That said, even just one DC charger installed at home costs would be significantly higher than $3K, probably at least $20k all inclusive.

I know at least 2 EV owners with solar who use their 19.2kw (and 22kW, as one is in Europe) to charge the car from solar, and halving the charging capacity makes the car unable to use solar during its peak production, so they would also require DC chargers (which interoperate with their solar) or perhaps a battery storage system installed and paid for my the car manufacturer to store the excess solar and then transfer it to the car later.
