The fleet club at Stad has 4 chargers in the visitor parking area. They’re usually turned off, but there’s a toggle switch on the side to turn them back on. You might need to power cycle them a couple of time before they’ll give a green connection, but they do work. For Tesla’s, they’re going to give you a grounding fault, and be limited to 22 amps at 208 v, but they’ve removed the time limits on those parking spots if you’re there to charge (I’ve tested leaving my X there all day without issue).
Other chargers I’ve used in downtown include the following:
1) the Eaton charger at Dalhousie DalTech campus. It’s the only 80amp level 2 charger in the area. Free to use, however it’s only available to the public after class hours (basically after 5pm). It’s accessible via the campus on Barrington, or there’s an access via the Halifax Public Library on Spring Garden road. There are also chargers in the Library’s parking structure, however it’s paid parking there.
2) there’s the Chademo/ccs Flo Charger at the Superstore on Barrington near the train station. Pay to use, of course.
3) two bullfrog chargers in the Scotia Square parking structure (check PlugShare for their level).
There are others scattered around, but those are my gotos when I need a charge. PlugShare is pretty up to date locally, and I highly recommend consulting it if you need to find power.
