Nice. Now the real question is how fast does the battery deteriorate. There is always a balance between speed, capactiy, and durability.

Seems like these batteries push more toward the speed and capacity side.

Why? What makes you say this? This skepticism seems unfounded.

BYD offers an industry-leading 8 year, 250,000km warranty. They are obviously confident about durability, and the proven durability of the gen1 battery is testament to their engineering prowess. The gen1 batteries are rated for 3000 to 4000 cycles. There’s a reason both Tesla and Caterpillar are starting to use BYD (finDreams) batteries.

Basic physics knowledge? Why would we disregard that based on the word of a corporation whose entire goal is to convince us to buy their products?

Warranties are a great way to build trust, but it’s still based on a promise, not the reality if the physical world. When a resource rich company wants to dominate a market, and push out competition, they will often promise these sorts of things to capture a market.

I won’t say that the technology isnt possible, or that they’re not providing… but going all in all at once based entirely on promises seems premature. And trying to shut down any potential criticism because of it seems suspect at best.

If you want people to trust in this, maybe engage with them instead of trying to shout them down.

If you want people to trust in this,

My point is not to run PR for BYD. I’m not trying to get people to trust a corporation. I’m just shutting down FUD (that is most likely rooted in sinophobia).

Yes, I understand the basic physics since I am an electrical engineer and work in the automotive space, and I integrate batteries into battery electric vehicles.

Regardless of your stance on warranties, corporate competition, or China… the original claim was “Seems like these batteries push more toward the speed and capacity side.”

Where is the evidence to support this claim? For what reason could anyone think that BYD’s design philosophy caters to performance over durability?

This happens all too often:

• An engineering feat is achieved
• A layman hops into the discussion to inform everyone about the concept of engineering tradeoffs (as if that is groundbreaking)
• The layman gives their uninformed opinion about why they think the tradeoff was ill considered

Here’s the simple truth: BYD’s entire battery design philosophy revolves around durability. If BYD was truly solely interested in battery density and charge speed, then why are they the primary champion of LFP batteries? If you were truly interested in performance and speed, LFP would be your last choice for battery chemistry. If anything, BYD leans more towards durability, safety, and longevity over performance - as is evidenced by their choice to make their entire design philosophy revolve around LFP. Teslas and Lucids lean towards Nickel Cobalt because Nickel Cobalt battery chemistry is fundamentally more performant than LFP batterys. THAT is “Basic Physics”.

So your refutation of skepticism is “you must be racist, so we should disregard this skepticism”?

You didn’t refute the physics or the claim, only showed that the company super promised they’d fix it if it went wrong.

If your background is in engineering, why didn’t you start from that instead of going into PR mode? It certainly seems more like damage control than alleviating actual concerns.
