No need to bookmark....160 chargers already full every work day....average 2MWh delivered per day. Each color is a different floor of the same parking lot. We will be starting several 300-400+ port installs in the same garage soon.

By popular demand Added protection

Usually $3k a port when 30+ ports. Lots of grants in California, sometimes we can get it done for net $0.

Here's another recent install...160+ stations, single garage. Stations as far as the eye can see! If your workplace is in California and needs 100+ stations, we can probably help. =)

Oops, my bad on the photos, been so long I forgot how to correct post photos! Anyway, on the research data side, we do have data sets on charge stations if people are interested: The Adaptive Charging Network - Caltech We have started to wire HPWC to 48A as less and less vehicles will have...

New site! Caltech North Wilson: (4) 50kW DC + (10) HPWC + (40) J1772

Construction for N Wilson garage is starting 9/16, should be done by 10/31. It will be (4) 50kW DC FC + (44) 32A J1772 + (10) 80A Tesla HPWC! I want to thank everyone for their contributions on this thread, its been an amazing journey from our first project at Caltech to be now deploying some...

Yep, you need the PowerFlex PWP 16 pack...optimized for the $50k rebate. We have several projects signed up in Pasadena already. =)

I can share some JPL photos...(52) Level 2 chargers across 3 floors

Thanks! I was wondering why my PWs were not charging from the grid during off peak weekends

Btcpower is coming to repair it this week. Probably something died in the power electronics module.

There will be a kiosk for those who don’t have a smartphone.

The RPi chargers were ones I built in my garage, mainly to submit our patents and demo the technology. Since then we have been using AeroVironment, ClipperCreek, and Tesla HPWCs. So sadly the RPis will all be removed in the coming weeks. 48A+ L2 charging will be available once we finish the next...

It's restricted area...I will have to leave it up to your imagination... However, I could share some other recent sites...we have a new site opening every 20 days or so now...comes in custom color poles, 4K cameras, adaptive load management =)

JPL / NASA (52 L2 Stations) is finally completed...20,000 miles delivered in the first 5 days...amazing things happen at JPL.

If you are in PGE territory and it looks like you are, have your HOA check out PGE's Charge Network program. PGE will cover the majority of the cost and poof you will have a lot of stations. This is 18 stations for an apartment building in mountain view, that I think only has 18 apartments...

I knew you were going to say that...there will be a few more DCFC as well.

we never install one or two of anything...its gonna be 20+

Let's just say there are more connectors coming. =)

Yes it’s alrady dynamic pricing depending on Real-time solar production. In addition you can opt in to 100% renewable source, but at a higher rate.

We were planning to deploy a kiosk, but so far we haven't had an issue with smartphone access. Or just go re-plug the car every 40 miles...lol.

Default anonymous session is now 40 miles or 4 hours which ever comes first. To unlock additional energy, use the PowerFlex mobile app. =)

max speed is 32A, we are still evaluating 48A and 80A hardware, no one has anything cost effective. We are focused on workplace charging which means increasing station count is more important than max charging speed. We would rather have all 100 EVs plug in and not have employees move their car...

We always install 80amps...I’m often disappointed by 32amp HPWCs.

Not at this location due to privacy concerns...other sites yes. We're going to try to hit 150 chargers by the end of the year. Infrastructure can easily handle that as its hovering around 150kW peak and ~3,000 miles delivered per day.

Quick Caltech update, daily EVs have been increasing! So to satisfy the demand, we've added another 22 stations this week.

los altos

One of our newest sites...(26) L2 + (1) L3 + (3) HPWC...fully load managed...cameras for parking occupancy detection and auto vehicle identification. More sites coming VERY soon.

I thought that looked familiar. We are doing a pilot at the wind site. Hope to do one at the main site some day.

Is that nrel?

Quick update...we've developed a mobile app for user input @ Caltech...It includes predictive charge curve Depending on your urgency and dynamic pricing, you can see how we plan to deliver that energy before departure time. We are delivering over 3000 EV miles a day now, which I guess...

Pw2 is simpler... but still to many items to install... Also they are still limited to 200A ATS.

I think my HPWC got updated or something...they no longer charge when sending a heartbeat...i have to spend some time over the weekend to see what changed...

apparently self powered mode is only available if you install the solar CTs...I have to get them to come back to do that. Is it possible to install the solar CTs on a dummy circuit and then use that to trigger self-powered mode?

Just got my two powerwalls installed last week...and without load shifting this thing is useless? Are people manually shutting off their main during the day to use their powerwalls during the day? Install an ATS in front of their ATS to simulate grid disconnect? LOL I think I am in the boat...

Hmm, maybe. Easiest way to tell is to get another HPWC and see if those messages come across...we see them every 10 seconds or so.

Yay! I am glad you got it working. Did you see the voltage and cumulative energy counters?

1f40 is pilot but usually not in that location. The slave command you are sending seems to be similar to what is received after a reset is sent. Make sure to maintain the heartbeat, the whole time. We also see messages once a second during a charge session. Makes sense as if another car plugs...

Should have gone with the $5 USB adapter...=) Why do you have a 40 in the command below? Switching HPWC rotary switch to 8 (40A master mode), I fake a message from a slave with 0A 51 id: C0 FD E2 0A 51 45 1F 40 00 00 00 00 00 00 E1 C0 FE

Switching pilots while charging Testbed in our office

The master tells the slave how much power is available. The slave will announce it's status...interestingly enough, the master does't reveal too much to the slave what it is doing. When the units are first powered on, there are some rapid fire redundant messages, probably to establish...

Get this USB RS485 adapter...https://www.amazon.com/JBtek-Converter-Adapter-ch340T-Supported/dp/B00NKAJGZM/ref=sr_1_3?ie=UTF8&qid=1509653243&sr=8-3&keywords=usb+rs485 if you only have one HPWC, set it to master say position 6...connect the RS485 usb to the output ports. listen to the packets...

yes over rs-485, raspberry pi + USB RS485 adapter works well for residential single HPWC control

Sneak peek

Only when they don't power limit. Supercharging speeds have been horrendous lately. I'm not sure I buy the fear of battery degradation part. There's too much time spent at 70kw speeds when it should be over 100kw. We need convince delta to make a 150kw ccs to tesla adapter. :)

No hardware upgrades needed. Just overclock it :) 150kw will be multi dispenser. Adaptive load balancing.

1 hour is the default set by the manufacturer, but then we asked them to override that to make it unlimited. Is this recently that you tested this? We're looking to add 150kW stations, so I guess soon you won't even have to wait 1 hour.

We don't have a time limit, but there might be a 1 hour default from the manufacturer...I'll have to see.
