CALB unveils new battery tech, boasting significant performance gains over traditional cylindrical cells

The "U" type structure allows the battery to reduce structural component resistance by 50 percent, achieve an energy density of 300 Wh/kg, and support fast charging beyond 6C, CALB said.  | CALB.HK

As CATL's Qilin Battery begins mass production, CALB, another Chinese battery manufacturer, has also rolled out its battery innovation.

CALB officially unveiled its new battery with a "U" type structure at the recent China EV 100 Forum event, an innovation based on its One-Stop minimalist design concept, according to an article by the CATL rival yesterday.

The battery is based on structural and chemical innovations developed by CALB in-house, the industry's first "U" type structure, according to the article, which features a presentation by an executive.

This design allows the battery to reduce the resistance of structural components by 50 percent, achieve an energy density of 300 Wh/kg, and support fast charging of more than 6C, achieving a significant increase in performance compared to traditional cylindrical batteries, according to CALB.

As background, C refers to the battery's charge multiplier, and 6C means that the battery could theoretically be fully charged in one-sixth of an hour -- 10 minutes.

"We have made a disruptive innovation to the structure of the cylindrical battery by introducing the 'U' type structure," CALB vice president Xie Qiu said in a presentation at the China EV 100 Forum.

While the Tabless structure solves some of the current path problems, treating the cell's shell as a conductive component results in a relatively long path for the current to flow through, Xie said, adding that the shell is steel, which does not conduct well.

CALB's structural innovation reduces the current flow path by 70 percent relative to Tabless cells, reduces structural resistance by 50 percent, and improves space utilization by 3 percent, he said.

Also considering CALB's chemical material system technology, the company's large cylindrical battery can achieve 6C fast charging while the energy density of the cells can reach 300 Wh/kg, according to Xie.

In addition to the performance improvement of the cells, the "U" type structure also helps to improve manufacturing efficiency. Compared with the Tabless technology, the number of welding machines in the production line of this battery is about 70 percent less, he said.

CALB is the latest local manufacturer to announce progress in battery technology innovation.

On June 23, 2022, CATL unveiled its CTP (cell to pack) 3.0 Qilin Battery, which it says brings battery system integration to a new level.

The Qilin Battery allows volume utilization to exceed 72 percent and energy density to reach 255 Wh/kg, easily allowing vehicles to achieve a range of 1000 km, CATL said at the time.

With the same chemistry system and the same pack size, Qilin Battery delivers 13 percent more power compared to the 4680 battery, achieving an overall improvement in range, fast charging, safety, longevity, efficiency, and low-temperature performance, according to CATL.

On March 21, local media outlet The Paper reported that CATL's Qilin Battery has achieved mass production.

CATL is the world's largest battery manufacturer, with a 33.9 percent share in January-February, according to data released by South Korean market research firm SNE Research on March 30.

CALB ranked seventh in the global market with a 3.4 percent share.

Notably, CATL is suing CALB in China for infringing its patent rights.

Tom Zhu becomes 1 of 4 key execs at Tesla

Zhu, 43, has been officially named senior vice president of Tesla's automotive business.

Tom Zhu, who has made significant contributions to the development of Tesla's China business, has been officially named one of the top four executives at the US electric vehicle (EV) maker.

Zhu, 43, has been named senior vice president of Tesla's automotive business, according to a filing the EV maker made with the US Securities and Exchange Commission yesterday.

"Tom Zhu has served as our Senior Vice President, Automotive since April 2023," the filing reads.

Here is a brief description of Zhu in the filing:

Mr. Zhu joined Tesla in April 2014, and served in various operational roles before being appointed as Vice President, Greater China, where he led the construction and operations of Gigafactory Shanghai.

Mr. Zhu holds a bachelor's degree of commerce in information technology from the Auckland University of Technology and an M.B.A. from Duke University.

Zhu joined Tesla in April 2014 as the director of the EV maker's Supercharger program in China.

In July 2019, he was mentioned in media reports as Tesla's global vice president and president of Greater China region.

Rumors of Zhu receiving a promotion at Tesla began to emerge from late last year.

On July 8, 2022, Bloomberg cited people familiar with the matter as saying that Tesla had changed its management structure in the Asia-Pacific region, with executives in the region now reporting to Greater China rather than the United States.

Senior executives in the region report to Zhu, then president of Tesla China, meaning he also oversees Tesla's Asia Pacific region, a position previously held by US executives, according to the report.

On December 8, local media outlet Ping West reported that Tesla CEO Elon Musk would have Zhu succeed him as CEO of the EV maker.

Zhu's CEO position would be global, but the scope of responsibilities would likely be limited to Tesla's automotive business and not include and robotics programs, the report said.

Zhu has been promoted to head Tesla's US assembly plants and sales operations in North America and Europe, Reuters said on January 3, citing an internal report line announcement.

The move makes Zhu the highest-profile Tesla executive since Elon Musk, with oversight for deliveries in all of its major markets and all of its production outside the still-ramping Tesla plant in Germany, the report noted.

Zhu's promotion is apparently related to Tesla's China business becoming increasingly important.

Tesla delivered 422,875 vehicles worldwide in the first quarter, including 412,180 Model 3 and Model Y vehicles and 10,695 Model S and Model X vehicles, according to figures it announced April 2.

Tesla's China-made vehicles delivered 229,322 units in the first quarter, up 25.88 percent from 182,174 units in the same quarter last year, according to data from the China Passenger Car Association (CPCA) monitored by CnEVPost.

This means that 54 percent of Tesla's global deliveries in the first quarter were made at the Shanghai plant.

Li Auto (NASDAQ: LI) is making the transition to pure electric vehicles, and that day may come sooner than many expected.

On April 18, the first day of the Shanghai auto show, Li Auto's all-electric solution will be officially unveiled with the launch of a "dual-energy strategy," the new energy vehicle (NEV) maker announced on its social media platforms late last night.

The upcoming biennial Shanghai auto show will be held at the National Exhibition and Convention Center from April 18-27, with press days from April 18-19 and professional visitor days from April 20-21, while the general public can enter from April 22-27.

Li Auto did not provide any additional information on its all-electric solution, saying only that those interested can visit its booth #6A04 in Hall 6.1 during the Shanghai auto show to learn more.

"We'll be waiting for you at the Shanghai auto show from April 18-April 27, 2023," Li Auto said.

Here's a map of its booth location at the Shanghai auto show, as announced by Li Auto.

Li Auto's current vehicles on sale -- Li L7, Li L8 and Li L9 -- are all extended-range electric vehicles (EREVs) with an electric range of around 200 kilometers and can be refueled.

In terms of product form, SUVs with extended-range technology are a more appropriate choice, and Li Auto's future pure electric models will bring products that are completely different from any other form currently on the market and will not impact existing products, Li Xiang, founder, chairman and CEO of Li Auto, said on Weibo last June.

For pure electric models, Li Auto will launch a product similar to the L series to meet demand in the RMB 200,000 ($2,9100) - $500,000 price range, the company's management said in a call with analysts on February 27 after announcing its fourth-quarter earnings.

Infrastructure is critical for future all-electric models, and users will need a charging experience close to that of a fuel car. Li Auto will use 800 V technology and has built its own silicon carbide module factory, its management said.

Real-world measurements show that Li Auto's products can save about 15 percent of battery capacity compared to mainstream 400 V, IGBT module products, resulting in significant cost reductions, according to the call.

Li Auto will allow two technology lines to develop in parallel, including optimizing the range extender for higher efficiency and making pure electric vehicle technology better, Li said in a March 2 media communication.

Early last month, one of Li Auto's under-construction 800 V charging stations was seen at a highway service area in China, sparking widespread discussion in the Chinese community.

On March 10, 36kr cited sources familiar with the matter as saying that Li Auto's infrastructure build-out will see an "NIO pace" and that the company has set a goal of building about 300 supercharging stations within the year, with about 10 already deployed in highway service areas.

The move is in preparation for the launch of Li Auto's first all-electric model, which will be an all-electric MPV expected to be released by the end of 2023, and ultra-fast charging will be one of the highlights of the vehicle, according to the report.

China’s Mar NEV retail sales at 549,000 units, preliminary CPCA data show

This was up 27 percent from February, but below the CPCA's estimate of around 560,000 units announced in late March.

Retail sales of new energy passenger vehicles (passenger NEVs) in China were 549,000 units in March, up 5 percent year-on-year and up 27 percent from February, preliminary figures released today by the China Passenger Car Association (CPCA) show.

Notably, the CPCA's estimate released on March 24 showed that retail sales of passenger NEVs in China in March were expected to be around 560,000 units.

The lower figure released today means that the NEV market performed weaker in the last week of March than the CPCA had expected.

In the first quarter, retail sales of passenger NEVs in China were 1.139 million units, up 15 percent from a year earlier, the CPCA said today.

Wholesale sales of passenger NEVs in China rose 32 percent to 599,000 units in March, up 21 percent from the previous month.

In the first quarter, wholesale sales of passenger NEVs in China were 1.483 million units, up 24 percent from a year earlier.

Retail sales of all passenger vehicles in China were 1.596 million units in March, flat from a year ago and up 17 percent from last February, according to the CPCA.

This means that the penetration of passenger NEVs at retail in March was 34.4 percent, up 2.8 percentage points from 31.6 percent in February.

In the first quarter, retail sales of all passenger vehicles in China were 4.275 million units, down 13 percent year-on-year.

Wholesale sales of passenger vehicles in China were 1.955 million units in March, up 7 percent year-on-year and up 22 percent from February.

In the first quarter, China's passenger car wholesale sales were 5.021 million units, down 8 percent year-on-year.

With a large number of car companies stepping up their promotions in March, demand for cars was concentrated, putting pressure on the normal order of the market, the CPCA said.

From the performance of the first four weeks of March, the conversion rate of customer traffic is not high, consumers were in a wait-and-see mood, and the overall demand was weak, the CPCA said.

Here are the CPCA's weekly retail sales data for the Chinese passenger vehicle market in March, as announced today:

Average daily retail sales of passenger vehicles in the first week of March were 31,000 units, down 16 percent year-on-year and down 14 percent from the same period in February.

Average daily sales for the second week of March were 37,000 units, down 18 percent year-on-year and down 8 percent from the same period in February.

Average daily sales for the third week of March were 41,000 units, up 10 percent year-on-year and up 7 percent from the same period in February.

Average daily sales for the fourth week of March were 46,000 units, up 18 percent year-on-year but down 35 percent from the same period in February.

Sales for the fifth week of March were reported at 115,000 units, up 3 percent year-on-year and up 63 percent from the same period in February.

Price wars fail to boost China’s auto consumption

With consumers in a wait-and-see mood, orders and transaction rates did not increase significantly, and auto demand recovered less than expected, the CADA said.

Price wars fail to boost China's auto consumption-CnEVPost

Many automakers in China launched rare price wars in March to try to boost sales. But these moves do not seem to have achieved the results they wanted.

In March, following significant promotions by automakers in Hubei province, dozens of provinces and cities, including Beijing, Tianjin, Shanghai and Zhejiang, offered deals that gave dealership store traffic a quick boost, the China Automobile Dealers Association (CADA) said in an April 3 report.

However, orders and transaction rates did not increase significantly as consumers were in a wait-and-see mood, and auto consumer demand did not recover as expected, the CADA said.

The Vehicle Inventory Alert Index for China's auto market was 62.4 percent in March, down 1.2 percentage points from a year ago but up 4.3 percentage points from February, according to the CADA report.

The index's break-even value is 50 percent, and a reading above that benchmark means the auto distribution industry is in contraction territory, according to the report.

China's switch to the 6b emissions standard was not the main reason for the wave of price cuts, the CADA said, adding that most dealers said their inventories of 6a-based vehicles are not high and could be cleared by the end of June.

However, there are still a large number of 6b-based vehicles that do not meet RDE (real-world driving emission) standards, and with lower-than-expected sales in the first quarter, these vehicles face challenges in completing inventory clearance by the end of June, the CADA said.

In March, vehicle prices were volatile and customer wait-and-see sentiment was strong, resulting in lower orders and turnover rates and a decline in dealer profitability, according to the report.

More than 60 percent of dealers said they met less than 80 percent of their sales targets in the first quarter. Of those, 20.5 percent of dealers achieved 70-80 percent of their sales targets and 46.0 percent achieved less than 70 percent, the CADA said.

Separately, the CADA said in another report on April 3 that the March auto consumption index was 72.5, down from 74.6 percent in February.

March auto sales did not meet expectations, and dealers predict that without major policy changes in April, auto sales will be essentially unchanged from March, the CADA said.

In March, the demand sub-index of the auto consumption index was 68.2, down from 73.3 in February, the CADA said, adding that this signals a decline in demand for cars in April.

General Motors' Buick brand will launch its first electric model based on the Ultium platform in China next week, in what could be one of the most anticipated EV offerings from a foreign brand here.

Buick will launch the Electra E5, a large five-seat all-electric SUV, in China on April 13 and will be offered in standard, long-range and Avenir four-wheel-drive versions, SAIC-GM, GM's joint venture in China, announced today.

The Electra E5 features the Pure Design concept, the new generation Virtual Cockpit System (VCS), and Buick eConnect network connectivity technology, SAIC-GM said.

The model will feature exclusive battery cells with a CLTC range of up to 620 km and can consume as little as 13.5 kWh per 100 km.

Its Avenir 4WD version will feature the Ultium 8-in-1 electric drive system with a permanent magnet synchronous motor in the front and an induction asynchronous motor in the rear.

The Avenir version uses a battery pack with a capacity of 80 kWh, offering strong performance and range, SAIC said.

China's Ministry of Industry and Information Technology released a list of models that will be allowed to be sold in China for public comment last November 16, and the Buick Electra was included.

The Electra E5, which entered the catalog at the time, has a single electric motor with 180 kW of peak power and a top speed of 180 km per hour.

The Buick Electra E5 measures 4,892 mm in length, 1,905 mm in width and 1,655 mm in height, and has a wheelbase of 2,954 mm, the filing data show.

Its power battery is a ternary lithium battery, and the supplier is a joint venture between Chinese power battery giant and SAIC.

The battery pack has a capacity of 68.4 kWh and will give the vehicle a CLTC range of 545 km.

Last December 19, Buick began warming up for the Electra E5, saying the model would be launched soon.

On December 28, Buick saw the first pilot vehicles of the Electra E5 roll off the line at the Ultium plant in Wuhan, Hubei province, central China.
