X-ray Vision Meets Comment Chaos
CT scans of BYD car parts
BYD’s car guts got X-rayed, and the comments instantly turned into a factory-floor fight
TLDR: Scans of BYD car parts gave people a rare look inside how the Chinese EV giant designs its own batteries and controls, showing why many think it has a big manufacturing edge. In the comments, fans were impressed, jokers had memes ready, and some were grumpy that the famous Blade battery wasn’t actually the one on display.
The big reveal here is that BYD isn’t just building electric cars — it’s basically building the whole car empire itself. The scans show the insides of a BYD battery cell and door controls in unusually close detail, and commenters were equal parts impressed, nitpicky, and ready to argue. One of the loudest reactions was basically: this is old-school industrial power in modern form. As one poster put it, BYD’s vertical integration — making its own parts instead of buying from lots of suppliers — feels like something “unseen since early 20th-century Ford.” For non-car nerds: that means BYD has way more control over cost, design, and speed than many rivals.
But the thread didn’t stay classy for long. A mini letdown hit when readers realized the scanned battery cell wasn’t actually BYD’s famous Blade battery, just a similar chemistry. That sparked some disappointed “wait, that’s not the star?” energy from people who came for the main attraction. Others immediately moved the goalposts and said the real juicy story is BYD’s integrated drive unit — the motor-and-axle package that some commenters say makes traditional carmakers look painfully slow.
And yes, there were jokes. The funniest was a riff on anti-piracy ads: “You wouldn’t CT scan a car!” Except, apparently, this crowd absolutely would, and even brought receipts with a personal example. The vibe was part admiration, part nerdy thirst, part “Detroit should be sweating.”
Key Points
- •The article analyzes CT scan views of a BYD LFP prismatic battery cell and the BYD Tang’s driver door control module.
- •The scanned battery cell is not a BYD Blade cell, but it uses the same lithium iron phosphate chemistry, which the article says offers thermal stability, long cycle life, and material-cost advantages.
- •CT images show the battery cell uses two parallel jellyroll electrode stacks, a pressure-relief valve, and layered anode, cathode, and separator structures inside an aluminum housing.
- •The article notes generally good electrode alignment and process control in the cell, but also identifies rippling in the jellyroll windings that may indicate uneven tension and potential long-term degradation risks.
- •The Tang’s door panel integrates multiple controls into one networked module using a PCB and tact switches connected over a LIN network to the vehicle body controller.
