In the 60s "made in Japan" meant "junk" until Honda and Toyota came along. In the USAF deployed to train with a Japanese F-15 Squadron in the early 90s one of my less PC fighter squadron mates responded to the question of a Japanese F-15J (J model F-15s were co-manufactured in Japan) pilot's question. "So Ringo-san what do you think the "J" stands for? Ringo-san responded "Junk". Fortunately our Japanese friends were excellent partiers, I've never since seen a larger Whiskey supply in one place. All was forgotten, including who was supposed to stay sober enough to drive our medium sized bus home. As I was held upside down by my friends for some infraction in the back of the bus I remember seeing our commander physically rip our valiant second in command out of the driver's seat because we were on the wrong side of the road (Japan has left hand drive) and take the wheel. In fighter pilot world at least by that time the Japanese had adopted the "Western" quality model. In debrief they acknowledged mistakes (they weren't worried about "loss of face"). Which is the key to being better. And they were fairly good, certainly better than some European AFs. Brits rest easy, your's is easily along with the Israelis the best. And that culture was reflected in Japan's products, which by that time led the world.We spent a lot of time in Korea then. We called it "The land of not quite right". They were building the crap out of that country then. Lot's of new shiny stuff. But everything from hotel rooms to cars to lighters had something wrong with it. They were still big into "face". And it was reflected into the quality of their AF. They didn't acknowledge their mistakes and didn't learn. We slaughtered them in training.They still haven't learned, at least in the airline world. The last 4 wrecks over 15 years they've had have been the same one. Where one or more experienced pilots sit on their hands and watch a more senior guy pile into the ground because they were afraid to bring up his mistakes.I've never been to China but 2 of my sons have been on technical fellowships. From what they told me sounds like early 90s Korea. That being said all the stuff in my off grid island house power system is Chinese. It's worked well. I did have a flawed BMS which I replaced with Ant BMS. But batteries, and solar charger/inverter have worked fine. The solar charger/inverter is the most impressive. 5kw. $900 compared to the $4k Victron equivalent. Even though it is excellent, I can't tell you a brand name without looking at it. That's their weakness, we can't figure out what's good or bad. In our culture bad products are exterminated fairly quickly by bad reviews and lawsuits. In their's if the company is state controlled or affiliated there's no such check. For me knowing nothing (it was getting in on friend's buy for free shipping, no small deal on an Island) it turned out well. But it could have been disastrous.Jerry BarthSent from my Sprint Tablet.-------- Original message --------From: "HF via groups.io" <incorridge=yahoo.com@groups.io>Date: 6/11/21 8:10 PM (GMT-04:00)Subject: Re: Chinese manufacturers and quality [electricboats] Anyone uses a used EV car battery for powering ?Hi Ryan, Jeff, and Capt. Carter,
Thanks for your comments!
Well, now that there's a thread regarding quality, I'll feel a little less constrained about writing my perspective on this topic. I've learned a bit about quality and "intellectual property" theft by running a business that involved manufacturing products. But what I know could fit on a sticky note relative to the volumes that some people on this forum know. I discovered the first theft of our intellectual property in Europe - not what I had expected, considering we had shipped more product to other places! Others later suggested to me that intellectual property theft is not likely to be a problem for my business because the volume available in my market is low. On giving it further thought, I realized that "intellectual property" is a pretty strange idea to someone who didn't grow up with it. So is a corporation. Or land ownership. They're all tools that exist because of what they enable.
Factories in China would not be as successful as they are if they weren't capable of excellent quality control. What varies over time and management direction is what happens to the products that fail the tests. Instead of sending them to a landfill, some factories let them flow out through other sales channels where quality headaches cannot return. Maybe that's why the 5000 mAh Li-ion cells I bought on ebay tested at ~515 mAh. "It *is* 5000 mAh, it even says so on the label!" The seller refunded my money but probably didn't hear any complaint from the other buyers. With moderate markup, a 5-10% customer return rate is very sustainable.
Back in the old days, faulty products in circulation would have had the factory's name on them. Long-term thinking meant it was very important what the company's reputation would be 5 months, 5 years, or even 5 decades later. Fortunately, such attitudes are hard to forget because they're in culture. They may no longer dominate, but they won't disappear. I don't think we can easily go back to the "old way" because short-term thinking is driven by shareholders who tend to invest for periods from a mere minutes to a few months. I think all three of you are adapting to a changing world. It *will* work because it *must* work and it's the only thing that *can* work!
Cheers,
Halden
