Chinese quality: BYD launches ‘Zero Defects’ as it crosses 113 GWh in Q3

This week, BYD crossed a major manufacturing milestone as its battery production crossed 113 GWh in the first three quarters of 2025 – but instead of celebrating, the company is doubling down with a new “Zero Defects” initiative to bring battery quality to an even higher level.

CarNewsChina reports that the new “Zero Defects” plan at BYD was launched internally at the start of Q3, with a focus on minimizing manufacturing defects across all stages of the battery’s life, from the manufacturing line to the end user.

The initiative coincides with BYD’s growing role as a battery supplier to other automakers and its expanding battery energy storage system (BESS) business, which are giving BYD both an international footprint and global benchmarks.

In its ongoing bid to prove itself even further in the global battery market, BYD will reportedly emphasize operational efficiency, error reduction, and standardization across manufacturing, process control, and customer service, with the end goal believed to be, “management practices comparable to those of Toyota.”

BYD on a charge

The Chinese automaker seems to be going from strength to strength in 2025, having overtaken EV sales leader Tesla in China back in June and repeating the trick again by overtaking Tesla sales in Europe in August.

Combine those EV sales with the fact that its domestic traction battery production reached 113.42 GWh in just the first three quarters of the year (with 23.65 GWh, or ~20%, being supplied to outside customers – including Tesla), and you might agree that betting against BYD seems to be a bad idea.

Note that BYD has not released official details regarding performance metrics or milestones for its new Zero Defects goal, but the message is clear: BYD plans to keep getting better.
