The article implies Canada requires the charging to be billed by per unit time rather than per unit energy.
I'm not familiar enough with the ecosystem overall, but I can see an argument that time based billing would make more sense. If it's the equipment that's the bottleneck, a price structure that incentivizes customers to charge quickly could increase throughput.
The example in the article was something like the cost is low for 5 min charging and then goes way up. This could encourage people to grab just what they need and then charge at home overnight (for example).
I'd be interested to hear more of an argument about why it's actually bad (or good)
I don't have a Tesla so I'm not familiar with the superchargers specifically but I have a plug-in hybrid and I have seen a combination of both time and energy at various charging stations. For example, some have a flat $/kWh + $/hour "parking" after the first hour.
I think that it makes a lot of sense to have some incentive for people to not just leave their cars there forever. But it is true that charging rates vary including a taper off in charging rate towards the end of charge if you are getting it "topped off" so to speak. So from that perspective basing it just off time does become a little disingenuous, and I like the hybrid approach of $/kWh + $/time that kicks in after some amount of time.
