Featured Demand for electric vehicle chargers exceeding what’s available: NB Power

do we really need a charger for every vehicle?

 

Are we counting public and private?

 

Yes! Every EV comes with a charger built-in.
We need lots of EVSE's as well.

Chicken & egg. You can look at shortages of either subject (charger VS ev's) & consider either the car chargers or lack of ev's in relation to each other as a problem or a blessing.
EDIT
On top of the notion there's not enough of "this or that" .... there's electricity. Here in the Pacific Northwest we are on a string of hydraulic dams' power. There are factions that want to tear dams down to help with fish migration .... lack of electrical power & flood controlling be damned. No pun intended. So in sum ... folks of extreme - if successful are going to do away with natural gas (for stoves) - hydropower & effective water storage & flood controls.

It's like TSA Precheck.....and Global Entry....Cool when new...now the lines are long as hell. One friday night in Miami I saw all 12 bays of Tesla Chargers full..and like another 12 cars waiting...but that is the first time I've seen a wait at a Tesla Charger.

 

"but there are plenty of tesla chargers in the province."

just another example of elons brilliance.

i think the problem msay be that canada, or parts of it, promote ev's with subsidies, but aren't focusing on charging stations as much as they need to be.
we have the same problem, but there are more charging companies installing stations. the author makes it sound like people only drive within the province

 

Once the factory is up and running, cars can be cranked out faster than chargers can be installed. Government has tools to help with charger installation and distribution, but with the market in a fast growth state, it will still take time for the infrastructure to catch up with the fleet.

 

The magic of "supply and demand" works in EVs and EV chargers.

Queuing theory provides formulas for determining the impact of people waiting to use needed resources. It comes down to scenarios where a resource will be needed at a specific locations where the consumers will have to stop for a period of time.

In the New Brunswick article, the problem is apparent when someone wants to drive from one part of the province to the other side. That can be as much as 220 miles one way in this specific case. EVs will need recharging if the length of the total trip will exceed the range of the car's battery. But here's the hitch. If most cars have a 200 mile range, then they will need to start with a fully charged battery and will need to charge before they reach their destination to ensure that they are not "running on empty" when they reach their destination. Even a long range Tesla with access to fast DC charging will need to charge at least once on a trip that's only 220 miles each way.

Now comes the "hitch in the get along" If you are traveling from South NB to North NB there is a good chance that you will start the drive within the same 2 hour window as most other travelers. If all of the cars have similar trip planning software they will be likely to suggest getting partial charges at the same points along the way. This will create congestion when 40% of the day's EV charging is requested in one spot within a very short time frame.

A much more challenging situation would face the cross country drivers in the arid south west. According to the government study ( https://azdot.gov/sites/default/files/media/2020/12/I10_Multimodal_Corridor_Study_Final_Report.pdf ) we have a situation where 25,000 cars will need to be charged on a desolate section of I-10 each day. By 2035 they expect 50,000 cars per day will be driving that 100 mile stretch from the California border to the outskirts of Phoenix. Some rough calculations show that 6000 car might try to charge at the same time to cover their end of trip needs.

Of course the NB scenario is also having to address the need for high power fast DC chargers for the cars that need it. They seem to have built out to provide level 2 charging for the cars with smaller batteries. That creates a much smaller load on the infrastructure.

 

by 2035, there will be plenty of charging stations

 

What makes you think that there will be plenty of stations, and are you addressing...
A) The original post about NB's lack of high power chargers, or
B) The post about charging when you have an extremely long trip that depletes the battery , or
C) The general state of the USA power situation?

 

Using Plugshare, here is NB and most of Maine:

• Compared to Maine, NB has nearly 3x the number of fast DC chargers, Tesla and CCS-1.
• The area east of Grand Falls appears to be 'thin', could use at least one more midway.

i was addressing you. 12 years will provide a lot of charging infrastructure. it's being built as we type
