I have read contradicting information on BYD manufacturing manual vs auto. Some said, high labour usage is key to BYD low cost manufacturing. BYD has denied this but never show any prove.
There is 2 piece of info which I find interesting:
- Wang bought order an fully automated production line from Sanyo in early days. He reserver engineered and make the same production line at a faction of the cost. So, I guess they do have some kind of automation.
- Wang has stressed BYD has not made any recall in the past which is a evident to their quality.
Other than cheap labour, some also said BYD copy cats way of 'R&D'. Foxconn who used to compete business with BYD for electronics manufacturing business, has criticize BYD repeatedly in front of media.
I hold the view that BYD do selective innovation, focusing on key area for product technology, while other less critical area are reversed engineered (copy cat) from competitors.

That is why domain knowledge is always key in looking at investment opportunities. Not just venture capital or private equity opportunities.
Macro picture is rosy, but micro evaluation requires strong domain knowledge looking into details and that makes a difference between a good and lousy research. Unfortunately most research out there are rubbish !
A Look Inside Buffett's Battery Bet
Asian Wall Street Journal, 11 December 2009
By MATTHEW FORNEY AND ARTHUR KROEBER
BYD reverted to manual assembly lines with inexpensive labor. The result was cheaply produced batteries of inconsistent quality. Although the company can rightly be proud that it has never faced a battery recall, it scraps 15-30% of its batteries because they fail to meet quality standards—far above the industry average of under 5%, according to German consultancy Roland Berger.
Inconsistent quality is a small problem when making mobile-phone batteries of one cell each: You simply scrap the batteries that don't make the grade. But it's an enormous problem for electric-car batteries, in which hundreds of cells, each the size of a pack of cigarettes, must charge and discharge with exact precision. A car battery works only as well as its worst cell. It is far from clear that BYD's labor-intensive process can achieve the uniformity of quality required for electric car batteries.
BYD has yet to bring a single hybrid or electric car to market and has repeatedly missed launch deadlines. Every BYD car sold to consumers so far has a traditional gasoline engine, and its models are popular in China not because they are high-tech but because they are ultra-cheap. The company claims its plug-in hybrid, the much-vaunted F3DM, went on sale a year ago. But this model has yet to appear in any dealership, leading industry observers to speculate its battery is not ready for prime time. The all-electric e6 was supposed to reach the U.S. this year, a launch date subsequently pushed out to 2011. But the e6 still hasn't passed Chinese safety tests, let alone more stringent U.S. tests. Advance reviews of prototypes have been scathing: Car and Driver reported, "We drive faster in our driveways."
