Is the DC charger at SuperStore on no.3 road free to use?
Also, what is the charging speed of that compared to other Level 2 chargers around the area?
Deciding whether I should buy the ChaDeMo adapter for $700
I believe the BC Hydro ChaDeMo chargers are all free for now and PlugShare also says it's free.
Charge rate is up to 50kW while most L2 stations are about 6kW so charge rate is quite a bit faster.
If you can charge at home, going somewhere like Superstore to charge for free isn't really worth it, unless you're shopping there anyhow, and even then saving $2-5 each time vs home charging will take forever to recover the cost of the ChaDeMo adapter.
The other thing to keep in mind is the stations at Superstore may see a lot of use, so unless you are there at off peak times you might not be able to charge. A friend did comment about a Superstore charger (I think it wasn't the Richmond one) being magic, because you park next to the in use charger and when you come out you find the other car is gone and your car has been plugged in.
You also might find the drivers of EVs with lower range (e.g. older Leafs) may be less than impressed with you charging a Tesla at those stations.
The main use case for the ChaDeMo adapter is if you're traveling somewhere that isn't serviced by the SuperCharger network. You may be able to use it for a bit of free fast charging but it's unlikely it will pay for itself that way before they start charging for the stations.
