Complaints Lodged Against BYD For Lower-Than-Advertised Qin Battery Range

JUN 22 2015 BY MARK KANE 18



WantChinaTimes reports that in China there are some complaints being filed in relation to the electric car battery in the BYD Qin plug-in hybrid.

We are not sure if the complaints are battery life (like the article title  suggest- “BYD gets complaints about electric car battery life“) or the actual range in general on the 13 kWh LiFePO4 battery.

Furthermore, there are only a few complaints – 10 in approximately in the past year, while total Qin sales have already exceed 27,000 in China (through the end of May).

“Ten out of the 25 complaints against BYD filed by owners between June 24, 2014 and June 6, 2015 were about its electric vehicle batteries, with major problems stemming from the real driving range of its electric cars being less than the company originally claimed and an insufficient remaining charge in the storage batteries.”

This could be just small group of customers who expected more range, or a tiny portion of cars with defects. We just don’t know, but hope to have more information specific to the complaints soon.

The BYD Qin is advertised as having a 70 km (44 mile) range in China.

“This could be just small group of customers who expected more range, or a tiny portion of cars with defects.”
Or it could be the very small percentage of customers who both believe that a complaint will change something and knows how to do it in a formal way that ends in such a public statement.

Not surprising in the least.

A chinese company exaggerating it’s ratings? Surely not. Seriously, everything they sell is an exaggeration. Here are other examples I have personal experience with:

Chinese scooters claim 20 miles range when in reality it is more like 3.

Chinese 18650 cells on ebay claim 6,500 mah, but in reality it is more like 1,000.

Chinese digital cameras claim 12 megapixels when in reality it is more like 3.

Chinese USB flash drives claim 256 GB when in reality it is more like 16 GB.

Chinese handheld HAM radio claims 8 watts, but in reality is more like 4.

See a pattern here?

I see more an exaggerating commenter.

Not exaggerations. I can show each and every one of these with factual science.. Oh, and I forgot one too. I bought a 600 amp motor controller for a conversion car I was doing. It didn’t seem to be providing as much power as I thought it should so I measured it and it was only outputting 300 amps max.

Yeah really just sop, for them.

You know what they say… Fool me once… … Maybe you should have learned something after 6 times…
But anyways, I still believe you exaggerate…

I’d never exaggerate! Not in a million years!

Did the FDA exaggerate when it said that Chinese pet treats were linked to hundreds of pet deaths and thousands of illnesses?

Did someone exaggerate when the Chinese were found to be using melamine and cyanuric acid to inflate the stated protein content in pet food and baby formula, resulting in hundreds of thousands of sick babies and at least six deaths and untold numbers of animal sickness and death?

Then there was the lead paint on children’s toys, etc., etc., etc.

Would a country which exports poisoned baby formula for profit lie about scooters and cameras?

I try not to buy any of their crap, most certainly their food products, but you are welcome to do so. Bon appetit!

If the car was that bad it would likely not sell so well (currently tops the Chinese PHEV/EV charts).

It will sell well if it’s the best of a bad batch of domestic (Chinese make) EVs. You can’t just look at the quality as a stand-alone product; you have to compare it to its competitors.

China has an overall severe problem with quality control in manufacturing, including outright counterfeiting of parts, especially in the field of electronics.

The situation in China is caveat emptor (“buyer beware”) in spades. It’s hard for someone raised in Western culture to comprehend how companies trying to cheat their customers at every turn could be so widespread. How could a company with such business practices stay in business? But when everyone in China is doing it, when it’s so commonplace that it’s accepted as the norm, then they can get away with it.

The “BYD Qin plug-in hybrid” (PHEV) is somewhat similar to a Chevy Volt having 13 kWh vs. the Volts 16+ kWh battery.

Minor differences in range for the Qin shouldn’t concern most customers as being a hybrid, they always have range extending capability.

Without data it’s hard to tell if range complaints are just a misunderstanding related to poor education, or marketing … or a technical issue in design, or manufacturing.

It’s great to hear there are over 27,000 BYD Qin’s on the road. This places the model higher up on the global EV list of production models.

It’s already #4 this year and closing in on the top three (leaf, tesla and outlander phev).

As a company BYD is number 7 in the world wide sales of EV/PHEV cars.

I’ve been following the Qin PHEV since it was released a year and a half ago. I frequent Chinese forums on a daily basis and this is what I’ve learnt so far. 1) Chinese sales reps are either incompetent or they try to hide any shortcomings of the cars they try to sell. This isn’t limited to BYD. So for example, the sales rep never mentions about range being lower during the the cold winter or hot summer. Or that your range will plummet if you get stuck in a 3 hour traffic jam. 2) The user manual of Chinese products are terrible! Absolutely terrible. And this applies to BYD too. The first edition of the 2014 Qin manual misses so many important features that owners need to be aware of. Such as the battery re-balance feature of the charger that comes with the car. 3) It is very important for the owner of the Qin to have access to charging. From what I’ve read, the main cause of reduced EV range is batteries becoming unbalanced. This usually happen to those who have no access to charging. Or people who aren’t aware that they need to use the re-balance feature… Read more »

In all fairness, this business practice isn’t limited to China. Look elsewhere on InsideEVs and you’ll see an article about Tesla Superchargers in the UK… in which Tesla claims you can get “up to 310 miles” on a charge. Hmmm, yeah, “up to 310” miles if you drive slowly enough! Certainly not when driving long distances at highway speeds, which is the usual case when drivers need to use a Supercharger.

Overall, “buyer beware!” applies much more in China than it does in first-world countries. But in this case… is BYD exaggerating its EV range any worse than any other EV maker doing the same? Nissan advertised the Leaf as a “100 mile EV” even in the first year of production, in 2011!

There are 2 versions of Qin – one with 10.5Ah At 501.6V other is 26Ah same voltage.

Guess complaints are related to the one with smaller capacity.

Sorry 20 and 26 Ah
