New EV Launch - Lucid Air
There's always something new in the world of EVs! Unlike Faraday Future, the Lucid seems to have a better approach to being a car startup...

Our first event notice for 2017!
I got the following message from our member, Doug Bursnall at CSU (Colorado Springs Utilities):
All,
Wanted to let you know that we’ll be undertaking our Conservation Open House again this year on June 3rd 10-2pm.
You
all were a great asset to the event and our customers with valuable
information on alternative fuels and transportation options. Hopefully
with more EVs now
on the market, we will have even more variety to show.
The invitation is open so please let me know if your available to attend and how we can help accommodate,
Regards,
Doug Bursnall

We have several new members this month!
First, L.D. Allan just bought a Nissan Leaf in December 2016. He (Lynn) previously had a Prius and made the switch to an all-electric only a few weeks ago. He already knows a few of our club members, so make him welcome when you see him. Lynn and his wife, Candace, live north in Colorado Springs.
Andrew & Marissa Streby joined us in January as well, and have a brand-spankin' new 2016 Tesla Model S60D, red. They live in the Peyton/Falcon area, so we hope to see them at our next meeting/event!

More charging explanation from our club member, David McNeil
Wilson,
You are correct, on the Tesla Supercharger Website https://www.tesla.com/supercharger under "How it Works" and "Engineered for performance"; it states, "Tesla is the only EV manufacturer capable of charging vehicles at up to 120 kW, (375 Volts x 320 Amps = 120 kW) which equates to about 170 miles of range in as little as 30 minutes."
The battery voltage for both the "S" and "X" is 375 Volts and that's what the Superchargers are built for. Since the Charge Point can go up to 400 kW (1000 Volts x 400 Amps = 400 kW) its only because they have the capability of going up to 1000 Volts. This may be for future vehicles like trucks or hybrid RV's.
To confuse you even further, the 240V AC (single phase) is referring to the charger input voltage, the charger is actually in your car, which has an output of 375V DC to charge the battery pack. The device in your garage is not really a charger but rather a means of applying the AC to the car's charger.
The Supercharger has an input voltage of 480V AC (three phase). It then produces an output of 375V DC that connects to the car and goes direct to the battery pack bypassing the smaller charger in the car.
The Chademo and CCS Combo kW outputs are dependent on their max output voltage and current. The battery voltage of other EV's range between 200 & 400 volts and would also be in the ball park of 120 kW.
If there was sufficient interest in this area I would be happy to give a presentation (dry-white board with simple block diagrams) to expand on all this.

Maybe I understand it now...
I'm sure the engineers among us will point out the details, but many of our members responded to my request for a comparison to commercial chargers and home charging. My takeaway is:
40-amp (at the plug) home charging is 10kW.
80-amp (at the plug) home charging is 20kW.
40-amp and 80-amp take into account the 80% rule for electrical circuits, meaning a 40-amp charger uses a 50-amp breaker in your panel (and a 100-amp breaker for the 80-amp).
The commercial charger mentioned in a previous post was lots more than those.
So my remaining question:
What's the kilowatt rating for
Tesla Supercharging (I thought I heard 120kW), Chademo and CCS Combo charging?
(and I don't mean to confuse us even more, but the DC Fast Chargers are all...DC. Home charging is AC, so may I assume AC vs. DC doesn't change the kilowatt rating?)

DC Fast Charging for everyone - Chargepoint
Chargepoint has announced new chargers for DC Fast Charging. Great idea!
https://chargedevs.com/newswire/chargepoint-express-plus-offers-dc-charging-at-up-to-400-kw/
For the curious, the specs of the unit are https://chargedevs.com/wp-content/uploads/2017/01/Express-250-Specs.pdf
Can some of our electrically aware members tell us if this unit charges faster than a 220v/80a home charger? It's rated at 31.25kW per module, with both modules producing 62.5kW. It appears both cables can be used simultaneously. The unit is DC, whereas home chargers are AC.
For your convenience, here is a kilowatt-to-amps calculator: http://www.rapidtables.com/calc/electric/kW_to_Amp_Calculator.htm

For your convenience, here is a kilowatt-to-amps calculator: http://www.rapidtables.com/calc/electric/kW_to_Amp_Calculator.htm
From David McNeil:
Wilson,
The Express 250 is the Station by itself
with two modules at 31.25kW each. It can distribute the total 62.5kW
output power to the two output cables according to the demand on each
cable. The Express Plus System can be a combination of Stations, Cubes
and Modules (contained in Cubes) to customize a DC Fast Charging
Facility with varying output capability up to a max of 400kW. The
modules and cables are liquid cooled with an available high altitude
option for elevations over 6500 feet (probably a different coolant).
The AC input voltage for the modules is 480 Volts, 3 Phase, which is
only available at commercial locations.
To answer your question, "Can they charge
faster than your home 220V 80A charger?" The answer is yes. Your home
charger mentioned has the maximum capability of 17.6kW, where the
minimum output of the Express 250 is almost twice that output.
For clarification, your 220V AC home
charger is a Level 2, which actually uses the charger built into your
car. The DC Fast Charger is a Level 3 which bypasses the charger in the
car and directs the DC from the fast charger direct to the batteries.
Communications between car and the Level 3 charger determines the output
voltage needed (between 200 and 1000 Volts DC) depending on the cars
battery voltage.

Move over Tesla, Faraday Future is here!
I thought Faraday Future was dead/bankrupt. They just showed a prototype sedan with better specs than a Tesla Model P100DL. Here's to competition!

Loveland, CO Supercharger ribbon cutting
Several of our members made it to the Loveland, CO Supercharger and had a ribbon cutting on New Year's weekend. The photos are below.

Newer Member EV accident
One of our newer members, Elizabeth Nguyen, unfortunately had an accident in her Tesla. Here's her post from Tesla Motors:
So the day started off great. We met some other Tesla owners at the ribbon cutting ceremony for the Loveland, CO SC Supercharger - Loveland, CO
Was coming back from that afterwards and decided to take a detour to do some grocery shopping. While waiting to turn left in the left turn lane, another car was driving towards us and drifted and plowed into the front driver side, instantly deploying the airbags for driver and passenger. it was a mess and the acrid smell from the airbags being deployed will stay with me for a long time. Fortunately, we are OK as is the other people in the other car. However, it had to be towed. I am still so angry at the senselessness of the whole thing and am grieving for my beloved Tesla.
We were fortunate that @MorrisonHiker and @DÆrik were in the area and were able to give us a lift home. Thanks, you guys are great people!
It's never a good time to have an accident and the senselessness of it is hard to take but it's NYE and nothing will be open until Tuesday, probably. It's a celebratory mood killer, too.
I know several people have posted about their accidents and differences in location can also contribute but I'm wondering if anyone has guesses on how long it'll take for this to get fixed (providing they don't total). I'll be driving a rental ICE in the meantime and hating every moment, I'm sure. We'll definitely be making sure they pay for diminished value but not sure there's much more I can do with this to alleviate the hassle.
