public off-grid solar charging

Tue May 04, 2021 1:06 am

Apparently EV ARC (https://beamforall.com/product/ev-arc-2020/) has come up a bunch. I never paid close attention.

I learned of one such location at https://www.plugshare.com/location/306233 in Santa Clara, CA via a Plugshare check-in. I'll have to swing by sometime.

It's mentioned at https://www.siliconvalleypower.com/sust ... g-stations.

I had seen some chatter about Electrify America deploying solar charging and per https://media.electrifyamerica.com/en-us/releases/128, it's also apparently EV ARC.
RESTON, VA (February 4, 2020) – Electrify America, the nation’s largest public ultra-fast charging network, has officially added 30 solar-powered electric vehicle (EV) charging stations with two Level 2 chargers each to its network in the state of California. The off-grid, standalone chargers are strategically located throughout the Central Valley and inland areas of Southern California, intended to provide greater access to sustainable EV charging for drivers in rural parts of the state.

These stations have got to have MONSTER batteries: let's say that 5 cars want charging after the sun goes down, each one wants about 30-40 kW, how is it possible to store this amount at a reasonable cost? Wow! and BTW, a friend in New Hampshire just had the local utility install 2 capacitor batteries, each one about 2.5 kWh and at a cost of about $2500 each. Claims that they can charge and discharge millions of times, very quickly...... anyone seen these?

So if you are a decent person you pop in for a 5 or 10 kw quickie and move on leaving some for the next driver...

Do you mean 5 or 10 kWh?

The spec sheet mentions total EV charger power of only 4.3 kW. So, it's not like vehicles can charge very quickly on these EV ARC units. To pull down 10 kWh with 4.3 kW max output would take about 2.3 hours.
