I don't know what they are talking about. BYD is already a leader in the US (of all places) in electric buses.
They might not be in automobiles but I think that is a matter of time.

Talking about Chinese EV, I think the best on the market now is Nio and the second should be BYD. Tang is the flagship of it. I think BYD is cheaper and more options available than Nio. Nio is pure EV, no other choice while BYD Tang is available in pure gasoline, plugin EV, pure EV. BYD comes to Cambodia recently (their showroom started open as soon as October). I think they did a market research and found that only pure gasoline suits the market of Cambodia. I think they did a common mistake as other Chinese car dealers that they set prices too high, almost as high as Japanese cars. For instant, Tang at US$53,000 and Song at US$39,000. I tested drive their car, I wanted to test the Tang but it was not available that day, so I tested the Song instead. I talked to the salesperson that if they want to sell cars in Cambodia, first they need to conquer the market. To do so, they need to set their prices at a discount ones. For example, Tang at $40,000. If higher than that they might never make a single sales. I nearly bought a Tang from them but they couldn't fulfill my conditions. The conditions I offered to them were:
1. Tang DM (they have pure gasoline version)
2. Model year 2021 which is already available in China (they currently have 2019)
3. Price at $40,000

After failing to buy a brand-new Tang DM, I turn to buy an American junk instead; the Lexus RX400h model year 2006. Price is no cheap either at $31,000. You guys might say: "Vow! I can buy it at a couples of thousand in the US!". Yes, that's right! but we pay more than $20,000 just for import tax of that thing!

In case you guys are interested, here's the vehicle that I bought.

A bit off topic. Here's how cars from the US comes to Cambodia

Some Chinese battery makers, such as BYD, CATL, and SVolt, are at the forefront of one of the most important technologies for EVs. Following CATL's steps, SVolt will also build a battery gigafactory in Germany, which can power 300,000-500,000 EVs a year.

China’s SVolt Energy Technology plans to invest about 2 billion euros ($2.4 billion) in Germany to build its first factory in Europe as the battery maker seeks to benefit from surging electric-car demand in the region.

The plant will have the capacity to make as much as 24 gigawatt-hours of batteries to power between 300,000 and 500,000 electric cars annually, the company said Tuesday in a

Production is slated to start at the end of 2023 at the site near Saarlouis, along Germany’s border with France.

The project echoes a move by larger Chinese peer Contemporary Amperex Technology Ltd. to open a battery plant on the home turf of German car giants Volkswagen, Daimler and BMW.

I know it's just joking. However, the fact these cars are stored in junk yard for quite a long time and importers go there to buy these cars by auction. To save transportation fees, they try to pack as many cars as possible into one container.

lol, when I was in Cambodia I was amused to see that there were a ton of second ha d Lexus SUVs shipped in from the US. Someone must have found some kind of channel for importing those to Cambodia and making a good profit. Nice cars though.

Can an OEM model like the one in electronics manufacturing work for EV? China just have too many car companies and merging them is almost impossible because local governments all want their own carmaker. Now EV is mechanically much simpler than traditional vehicle (no gearbox for example), and really is more about software (crucial components like batteries are expected to be made by third party suppliers). I'm thinking if moving toward an OEM model of manufacturing would make sense here. I have little hope in Chinese automobile SOEs to develop software as efficiently as Tesla. So wouldn't it be better if the SOEs just become OEMs to manufacture designs by new companies like Nio or XPeng?

This invention will speed up the end of internal combustion engine . With one fell swoop China will leap frog the automobile technology . If this is true if will be truly stunning development So far the one that hinder wide spread adoption of EV is the long charging time and range of batter But new company CAG promise to change all that

GAC expects graphene batteries that can be charged to 85% in 8 mins to begin testing at year-end
2020-11-23 21:54:55

Chinese automaker GAC's graphene battery research and development is ongoing, and the technology is expected to be tested in production vehicles by the end of this year, the company said today, adding that whether it can eventually be put into mass production will have to await the results of real-vehicle testing.

According to GAC's claim, the graphene "super-fast-charging battery" can be recharged to 85 percent in just eight minutes.

If the final data is true, the charging time will be comparable to the refueling time of traditional fuel cars, which will also be a technological revolution for new energy vehicle batteries.

On May 13, GAC Group's new energy department announced that graphene battery mass production research and development work will come out of the laboratory and mass production of vehicles, and by the end of this year, graphene battery technology will be equipped on some models of GAC's new energy Aion line.
This is another demonstration of the key technology in the battery field by China's independent auto brands after BYD launched its blade battery.

GAC started the research and development of graphene technology back in 2014. After nearly six years of exploration, GAC has gradually mastered the preparation and application technology of three-dimensional structural graphene (3DG) material with independent intellectual property rights.

In November 2019, GAC's self-developed "super-fast-charging battery" based on 3DG material was officially announced to the public.

Currently, new energy vehicles are expensive, mainly due to the expensive batteries used in them.

The battery of a new energy vehicle can account for about 40% of the cost of the vehicle, and the price of a new energy vehicle priced at 200,000 RMB is estimated to be between 70,000 RMB and 80,000 RMB. This is also the reason why new energy vehicles are generally more expensive than traditional internal combustion engine vehicles in recent years.

However, the main influence on the promotion of new energy vehicles is the battery's mileage and charging time, if GAC can solve the problem of battery fast charging, it will have a positive impact on the promotion of new energy vehicle

Chinese auto maker GAC says its technology allows EVs to exceed 1,000 km range
2020-07-29 20:30:05 GMT+8 | cnTechPost



Chinese automobile maker GAC Group said on Tuesday it has achieved an energy density of 275 watt-hours per kilogram of square hard-shell cells using a new silicon anode material technology, enabling electric vehicles equipped with such batteries to have a range of more than 1,000 kilometers.

At its Technology Day event held on July 28, the company said it had mastered the technology for the next generation of power battery cells.

This includes unique core technologies in battery materials, cell design, production process, manufacturing equipment, quality control, and other fields, and will be the first time in the world to apply new silicon anode materials to large power battery cell products, said Mei Untong, head of the Battery Research and Development Department at the New Energy Technology Center of the GAC Group Research Institute.

This not only allows the electric vehicle to exceed 1,000 km range but also provides lower cost and better safety.

In addition to the range, GAC Group has also achieved a new breakthrough in battery charging speed.

GAC Group has been researching the large-scale preparation of graphene since 2014, and already has independent intellectual property rights for the 3DG graphene preparation technology.

The company is also using the graphene material in a variety of applications, including fast-charging lithium-ion batteries, supercapacitors, lithium-sulfur batteries, and lightweight body materials.


The company claims that its 3DG preparation method is simple, stable, and efficient, and the resulting 3D multi-stage pore structure graphene can effectively overcome cost defects, with production and preparation costs up to 1/10 of those of conventional preparation methods.

Based on graphene's excellent electrical conductivity and special 3D structure, GAC Group has developed a super fast-charging battery that can be charged to 80% in 8 minutes. It can be recharged in 10 minutes and has a range of 200-300 km.

Currently, GAC Group has already conducted preliminary validation of the graphene technology at multiple levels, from the cell, module, to the entire vehicle.

The GAC Group says that a new era of electric vehicles will begin after the completion of mass production testing on board.

The problem with fast changing isn't just the batteries. You also need high power voltage lines for that widespread everywhere.
It is one reason why I think the next revolution in China could very well be the electric grid connections.

Will that involve lots of road digging?
