Does anyone know if they have looked at how charging quickly impacts the longevity of the battery? Can the cells be damaged by the rapid increase in temperature and current?

I looked, but didn't find anything. Perhaps it's too early to tell?

This will be a logistical challenge for the grid but absolutely fantastic for BYD owners in particular.

> it is now deploying 2.4 times more charging power per month than Tesla adds to its Supercharger network

And this is fantastic for EV owners in general, assuming the charging network is open to all.

> In short, BYD isn’t just shipping cars to Canada – it’s planning to build and operate its own charging infrastructure

They're mastering the "don't build on someone else's foundation" philosophy. Vertical integration is a very powerful tool.

As an American, I'm going to be really sad when we miss this transition. Maybe there's still time?

It will happen. My guess is that Canada is BYD’s pilot into the US. They have very similar buyer characteristics and the Canadian tariff deal allows them to enter the market without taking the risks of local factories.

It won’t take much to get BYD access to the US. It’s a two-step process:

- Toss a million bucks at Trump or wait for a Democratic administration

- Build a plant in Alabama/Tennessee/South Carolina/Georgia

That’s literally all it takes.

Interestingly BYD actually puts batteries next to these chargers that they charge "off peak" to minimise the strain on the grid. So often times cars will actually charge from that battery instead of directly from the grid.

Even if it did, this type of rapid charging only happens on long road trips.

I don’t specifically know for this type of battery but I’ve looked at pretty in-depth analysis of smartphone batteries (way less sophisticated battery management tech) and fast versus slow charging made very little lifespan difference. The best mitigations were fewer cycles and keeping the battery in its sweet spot (not discharging to 0% and charging to 100%)

I read an article recently that said something along the lines of “China is pausing on the idea of a BYD Mexico factory over fears of US stealing their technology.”

Isn’t it ironic? Don’t ya think?
