Best I've seen for conductive charging is 96%. They are using several different frequencies for different solutions: 85 kHz for small autos, 20 or 40 kHz for larger truck chargers. For how this is working, check out the website I posted earlier.

Re: [EVDL] Dual L3 PV-EVSE @Camp_Roberts-CA rest-areas along (SoCal) Hwy-101
$600K per station ? What, do they include a free Tesla when you come to
charge ?
Ok, so they have 1.56MW generation and 567kWh of storage, which is
probably on par with $600K * 2. So, they can fill the battery in about
20 minutes. What happens to the rest of the power ? Goes to the grid ?

“We’re thrilled to have these solar-powered EV charging stations up and
running in rest areas. It’s an important part of our overall plan to provide
sustainable transportation options for travelers,” said Caltrans District 5
Director Tim Gubbins.
These EV ARC 2020 stations include four solar panels that pivot to track the
sun, storing the captured energy in a series of batteries. This system will
power one Charge Point Express250 charging station at each rest area. These
charging stations offer CCS1 and CHAdeMO cables. Tesla drivers can also use
the station if they carry an adapter. Other motorists can assess the
availability of the ChargePoint Station through an application on their
smartphone.
These stations will be free to the public and were funded by the Monterey
Bay Air Resources Board (MBARD) at a cost of $1.2 million, which includes
long-term system maintenance.

“MBARD is pleased to partner with Caltrans District 5 on this unique
electric vehicle infrastructure project which makes DC charging available at
the Camp Roberts rest areas,” said Richard A. Stedman, MBARD Air Pollution
Control Officer. “This strategic location on Highway 101 fills a gap in the
network of charging stations along this important transportation corridor.
By funding the installation of fast charging stations, MBARD promotes the
adoption of fully electric vehicles, leading to significant long-term air
quality benefits.”
Emergency responders will also be able to use these facilities as an
emergency generator during a power outage in the event of an earthquake or
wildfire.
The installation of this technology was performed by Envision Solar
International, the developer and manufacturer of this system. “Envision
Solar is delighted to have the opportunity to put our environmentally
sustainable, off the grid EV charging solution on California’s highway,”
said Desmond Wheatley, CEO of Envision Solar International. These stations
are designed to fill a gap in the electric highway network to relieve driver
anxiety while encouraging longer travel trips by electric vehicles.
A third solar-powered EV charging station will be installed at the Shandon
Rest Area in early 2020.

100+ Teslas destroys Guinness World Record!!!
Tesla Owners Taiwan’s impressive Autopilot Day demonstration
]
Over 100 Tesla Model S, Model X, and Model 3 owners from Taiwan recently
flexed their vehicles’ Autopilot features, holding a mass demonstration of
the robust driver-assist suite’s capabilities. The event was a success, to
the point where the group could have easily broken a Guinness World Record.
Tesla Owners Taiwan [
https://twitter.com/teslaownerstwn
], a group of electric car enthusiasts, recently held an event dubbed
“Autopilot Day.” The event’s purpose was twofold: one, it was meant to
provide an impressive demo of Autopilot’s capabilities, and two, it was
meant as an informal challenge to Changan Automobile, the holder of the
Guinness World Record for the “largest parade of autonomous cars.”
Back in January, Guinness announced that the Chinese automaker was able to
set the record at a test track using 55 SUVs that were operating without
driver input. For the attempt, Changan engineers made specific alterations
to the vehicles’ systems, including upgrades to their sensors to ensure that
each SUV in the parade was properly positioned, and improvements on the
cars’ decision and movement control. The demo took 9:07, with the 55
vehicles traveling a 2-mile test track at 18.6 mph.
The Autopilot Day demo [
https://www.teslarati.com/tesla-navigate-on-autopilot-wins-germany-cci-award-2019/
] from Taiwan was a lot less informal, though it involved far more vehicles
compared to the Guinness World Record holder. Over 100 Tesla owners showed
up for the demonstration, which appeared to have been held in a closed area.
Footage of the event showed long lines of Tesla’s electric cars, grouped
together by color, traveling in unison on Autopilot. The demonstration
seemed brief, but it was an impressive show nonetheless, with some local
media outlets covering the event.
Granted, the Tesla owners from Taiwan did not beat the Guinness World Record
with their Autopilot Day event, considering that Tesla’s Full Self-Driving
suite has not been fully released yet. Advanced functions such as Navigate
on Autopilot with automatic lane changes and Smart Summon are part of
Tesla’s FSD package, though features such as city driving and road sign
recognition are yet to be released. Elon Musk has nevertheless mentioned
that the company’s autonomous driving technology will be feature complete in
the near future.
If Tesla does release a feature-complete version of its Full Self-Driving
suite within the next year, it appears that a new Guinness World Record
might be at hand for the company. Taiwan’s Tesla owners will likely be ready
for an official Guinness attempt, especially considering that the group was
pretty much able to trample the actual record for “largest parade of
autonomous cars” in terms of fleet size, despite using a driver-assist
system that is not fully autonomous.

My power load worst case would be either during the hottest or coldest time of the year, where I'll have a combination Air-conditioner/heater unit that plugs into a 6-20 outlet, plus one 5-20 outlet to power the refrigerator, & communications (phone, TV, etc.). I'm thinking a 6kW rated genset running at reduced load would work well. Assuming not central air or electric heat, I would guess that 6kw will work for you. I mostly get through nights on my 14kwh PowerWall using a 600 watt air conditioner at night during hot months. During the day, it is a 1500 watt unit and I usually just leave the 600w on since I have surplus PV power. My nights average about 500w (the air conditioner cycles) and day time use is around 2kw, maybe a bit less. Peak loads, without EV charging, are 3-4kw. I was expecting August to be the most stressing month with night time air conditioning ending sometime in September. Not so this year. I'm still running the air conditioner into October. The shorter days with longer nights have me supplementing the PW in order to avoid grid power use; I've been adding 2-3kwh each night. ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
