Re: Adding DC fast charge after purchase?

[quote][quote="phil0909"]What's your use case? Just curious.

Driving to and from Orange County from San Diego. I visit some family friends about once every month, and they live about 100 miles away. On paper, getting there and back without charging along the way shouldn't be an issue, but that assumes that I can maintain 4 mi/kWh the whole way. I'm finding that freeway driving might make that a bit optimistic. I can charge at their house, but the included EVSE only adds 4 miles / hour of charging - so that may or may not be helpful, depending on how long we visit.

Ultimately, upgrading the included EVSE for 220V is probably my best bet - my pal has 220V outlets in his garage, and adding 8 miles / hour of charging would probably be enough.

This assumes that charging wouldn't slow down as the battery fills up, which isn't what happens, so in reality it'd take longer to get to a full charge, but let's ignore that for simplicity. So if you were driving at a steady 60 MPH, it'd take you 4 hours to empty the battery (again, optimistic assumptions on efficiency at highway speeds apply) and another 1.33 hours to fill back up - not very appealing.


Full charge on a DCFC will be over two hours. I hit 87% SoC in 90 minutes and at that point was adding around 2% per every 5 minutes (16kW charge rate) and I would imagine there would be another taper coming before it hit 100%. I was not willing to sit on the charger for another hour to find out.

I installed a 6 kW EVSE at a friend's house on the other side of the city, it became my private satellite charging station. Later on she bought her own EV and uses it too. It gets 15-20 miles per hour while I'm visiting, much better even than stopping at a DCFC enroute.

Sounds like a sweet deal for both of you! Win-win!

Ironically, if Nissan hadn't been so slow to budge on the high residuals in 2013 (looking at you now, GM!) they could have sold a lot more of them to lessees for more than $10, and seen a lot fewer of them auction for much less than that.


True, but they made a lot of us second hand buyers very happy! :D

We have level 2 chargers down here in San Diego too. Just hooking up to one of those for a couple hours for a top off might be enough if it looks like you're going to come up short.

The EVSE that comes with the Bolt is, as I understand it, the same one that comes with the Gen2 Volt, and that EVSE can run on either 120V or 240V by autosensing the line voltage. You just have to make an adapter that will allow its 120V plug to be plugged into a 240V socket (and be sure not to use that adapter for anything else!!!)

Here is a stupid question. Can a non-fast charge Chevy Bolt use the css charger for just level 2 charging?

If you mean the CCS charger, no it can't

If you do not have the capacity to use CSS DCFC charging in your Chevy Bolt EV, then invest the in adapter that allows you to use the Level 2 Tesla chargers that many hotels/motels installed over the years. It expands your Level 2 charging availability exponentially:
