Probably true. If electric semi-trucks are the goal, and you want them to charge quickly with their ENORMOUS 600kWh to 1000kWh capacity batteries, you would need numerous 1.25MW chargers to accommodate as many vehicles that would be charging. So if you have a truck stop with 10 chargers, you need 12.5MW.
It would probably be closer to 15MW considering the (in)efficiency of the charging equipment. And that's not taking in the 'cold' factor.

The following is for home chargers but should be around the same for commercial ones

Staffers charging at home using a typical 120-volt wall outlet saw efficiency of, at best, 85 percent, and it dropped to as little as 60 percent in very cold weather, when charging the battery requires expending significant energy to keep it warm.

But while there is a carbon price before it gets sold the EV stops producing CO2 at that point in its life while the ICE vehicle just keeps producing CO2 as long as it runs ... it's a trite point that has been busted before in this thread ...
Like ev are cheaper to run than deez... it's a trite point that has been busted before in this thread :135:
Like this:
Using this emission data, it is safe to conclude that an electric car and a fuel car are equally harmful to the environment for the first 20 months or so. The difference kicks in thereafter. After the first 20 months, electric cars are way less polluting than their ICE-powered counterparts.
https://www.cnbctv18.com/auto/evs-or-*bleep* ... 184562.htm

Whereas searching for articles covering the assertion that EVs are cheaper being a busted myth:
In general, an initial new EV purchase price is going to be higher, but charging costs will be less than half of what it costs to pump gas, and vehicle maintenance costs will be reduced by about 35 percent.

Sure. Sounds like something a small nuclear reactor would be suited for… up around 15MW. Any EV revolution won’t happen solely on wind and solar. Heck, even if the whole world was powered by nuclear with tons of energy to spare, the EV revolution still won’t happen due to extreme raw material shortages and product cost.

We don't get salty hurricanes, but we do get atmospheric rivers :200: [icon_lol2.gif]
Either way here is some interesting facts and stats to keep in mind.

After hurricane Ian, reports are still coming in regards to EV fires. Some newer reports claim 15 fires so far with 8 verified. Once salt water gets in to the battery compartment(s), corrosion takes place and a fire can develop weeks or months after the fact. This fact has led to a growing graveyard of EVs.

Once your EV has been exposed to salt water, or any corrosive conditions, the risks greatly increase.

Most ppl dont drive in a ocean. Salt water can corrode wires in a non ev and lead to fires . Also once any car is flooded by saltwater it is ruined . This is a non point . [icon_lol2.gif]

Except now your EVs have the potential to explode at any time, any place if they are still drivable. Doesn't have to be completely flooded, just have to get any salt water content in to the battery compartment. Salt water can also splash on roads, and flooding doesn't have to be very deep to ruin an EV. Salt water is conductive too so galvanic reactions occur making EVs more vulnerable.

Did they put electric engines in small cars ? Cause i met a guy that put ev in small cars n trucks with his daughter ?

Careful where you plug your EV in, it may get destroyed. Like all electronic systems, they are vulnerable to electrical noise, or who knows what else.

Two Leafs affected. Other cars were unaffected. Careful of that pesky water in the gas station tanks. Or putting gas in a diesel car. Oh my. The horrors.

Sure, it doesn’t happen often, but it is NOT a $7000 repair where they keep your vehicle for a week, and they don’t have to replace the gas station. She bought her leaf used with no warranty. Hopefully BC Hydro helps.

Watch the part where the vid discusses carbon neutral gas. EV may find a balance with ICE which makes sense for the power grids in many circumstances.
