Re: my Facebook comment, pre-COVID, it sounded like Facebook had EV valets. I spoke to a guy at my work who used to work for FB and found it sometimes difficult to deal w/the car shuffling at my work due to meetings. He's a manager so that means he has lots of meetings. Sounded like he just dropped off his car at FB and the valets took care of charging it.
My work also had EV valets long ago when our parking was so full, we had to have parking valets. They doubled as EV valets but we had limited #s of plugs and they could only handle so many vehicles due to charging time and lack of DC FCs. FB most definitely has some DC FCs for employee use, as well. They're listed on ChargePoint's map if you check around Menlo Park, CA.
Also, post-valet but pre-COVID-19, my work was trialing using
Mobi EV Charger - FreeWire Technologies. We had at least 3 of these on a trial and a guy who would go around moving the "mobile" batteries (they're motorized and very heavy) to cars lined up to charge in a designated area then charging them for a designated amount of time. IIRC, their output was 5 or 5.5 kW per handle.
I believe my work ordered some and wanted to make it permanent but now I have no idea where that stands now due to COVID.
Almost nobody is going to the office now due to COVID and it might be this way until months after a safe and effective vaccine is available. The numbers I gathered are so low, there's no way we're hitting even 25% utilization of our existing charging stations now.
