Any GTAM'ers own an electric vehicle?

I was already considering installing a panel in the garage, but if I go with a 100A panel, am I limited to a total of 100A of breakers (2 x 50 for the charging outlets), or can I also have an additional 2 x 30A circuits for my 5000W heater and small MIG welder?



Interesting the code allows you to crush electrical cable but won't let you share an outlet that's already protected by a breaker - no different from overloading the kitchen outlets by plugging in too many appliances.

The only problem I see with what you’re proposing is the second charger. I think the inspector would question that, otherwise you would be fine in my opinion.You forgot the circuit for the 60 gallon 240V compressor.Your chargers are considered a continuous load ( anything that could potentially stay on for 3 or more hours) , they typically draw 40 amps each, a total of 80 amps so your at the maximum allowable continuous load (80%) of your 100 amp conductors and panel without your heater, welder, compressor which are non continuous, cycling loads and factored in at a reduced percentage.

You can always go with load sharing. No need for separate runs and breakers. Simpleswitch and Evolt as an example. Not cheap but it works if you're power-constrained at the panel.

That works if you're not running a fleet where all the vehicles need a whole night's sleep. A delivery company in Nova Scotia ordered all new EV trucks and the utility wouldn't give them enough power to charge everything overnight.

Heavy trucks have a different set of circumstances.

I also wonder about apartments. There are a bunch of sixplexes near me and that could represent a dozen cars each.
 
Those solutions are beyond my knowledge, although I'm sure it's already been solved in Norway and China since they are pretty much the leaders in electrification initiatives. Looks like Sweden is going all-out now as well.

Without the full story, it looks like someone in Nova Scotia didn't do their homework or consult before deciding to switch over to an EV fleet and that's on them.

NS obviously didn't do the research, thinking it was like using cube taps or power bars in the kitchen. A lot of people aren't any smarter.

I don't know what the learning curve will be like. Sixty percent of the population overloads their credit cards.

There's an interesting psychiatric discussion on whether ignorant people can be taught to think once they're past a certain age. Nanny state syndrome.

Canada has enough surface area for solar and wind but at what development cost? The government will be involved and I doubt we will be ready for whatever date they arbitrarily pick. Has any government project ever come in on time and budget and the little guy gets stuck with the bill.

The last time I checked with a friend in the condo electrical field he said they only put in a few charge points on one floor, maybe a dozen. Fast charging with cooperation by drivers will help but we, if anything, are going anti cooperation. Plug hogging will be a issue.

Good public transit could help but we're losing ground there due to short sighted politicians. We need immigrants. Immigrants need housing. Housing needs land. Expanded land needs transit, private or public.

When you solve a problem you have to take it to the final step. Politicians just kick the can down the road a few years.

The average person IMO is either out of touch with the situation or to busy and tired to care.

If a full charge gives a similar range as a tank of gas, say 500 Kms, 1000 charges X 500 Km = 500,000 Kms. Few ICE cars last that long.

Part 3 is the charging station. To put 80 Kwh (80,000 watts) into the battery you need to feed it through the charge cable. According to my math that's 80 amps X 1000 volts for an hour. A six minute charge is ten times the rate, either 800 amps @ 1000 volts or 80 amps @ 10,000 volts. Those rates scare me.

 
Most of the "charge in 5 minutes!" stuff is AI clickbait. The CCS connector is rated for 1000 volts and 500 amps - that's 500 kW if both were maxed out. Some cars are using 800 volts nominal. The amps are limited by the cross section of the copper; how much do you want the cable to weigh?

I've worked with solid 50 MCM. It's referred to as young crowbar.
 
Bit of an arms race between the manufacturers fueling the charge times...ironic since apparently most evs are charged at home.
That said ...pushing the envelope to see what is possible is useful and if a public charger can fuel 10 cars in an hour instead of 5 ...that's a lot less infrastructure needed to build out.
🍿
I'm just happy seeing the faster charge times on the smaller vehicles...E-mopeds, eMotorcycles etc and it's already showing in the vehicles available.
Tough time for manufacturers to choose a battery tech.:unsure:

Me thinks it's more of a race between advertisers pumping out fake facts.
