CTP technology (CellTopack, no module technology) is aware of the original battery pack, such as BYD's blade battery, is applied to the specific performance of CTP technology to "exiting". The BYDCK model with the blade battery has been sought after by the market. BYD Han July sales reached 1205, sales exceeded 4,000 markings in August, this achievement is very good for the price of more than 200,000 models.

As early as Chengdu Auto Show, Zhao Changjiang, general manager of BYD Auto Sales Company, pointed out that Han EV accumulated orders have exceeded 30,000 vehicles. According to the data given by BYD, the battery pack is reshaped, which reduces the blade battery to decrease by 30% more, and the unit volume energy density is 50%. It is equivalent to the original 300,000 electric cars.

Now it can be cut 3 .6 million (according to the cost of battery costs);. In the 2019 Performance Explanation Conference held in May this year, the Chairman of Ningde Times said that in 2016 Ningde Times has been mass production CTP structure battery, currently include CTP-0, CTP-1, CTP-2, etc.

In the commercial vehicle, a number of products is implemented on a passenger car. North Stroke New Energy EU5 model is a battery pack based on CTP structure in Ningde Times. According to the information released by Ningde Times, the volume utilization of CTP battery pack has increased by 15% -20%.

The number of battery pack parts is reduced by 40%, and the production efficiency is 50%, which greatly reduces the manufacturing cost of the power lithium battery. However, one is that the CTP technology launched by BYD and Ningde Times is based on the structural innovation on square batteries. So, can CTP technology innovation in the fast-growing soft bag battery? The soft bag battery is rising Although the soft bag battery is not a market mainstream package form, for example, in the first-July soft bag battery in the entire new energy vehicle power lithium battery installed, the soft bag battery is only 5%, but This does not cover the market demand and potential of the soft bag battery.

As early as 2018, Fu Can Technology has signed a cooperation agreement with Daimler, according to the contract, 2021 to 2027, Fu Can Technology will supply the total scale of 140GWH products for Mercedes, equivalent to 2.8 million pure electric cars battery installed capacity. Since Fu Can Technology only focuses on the production and sales of soft bag batteries, it is supplied to Daimler's batteries, which will only be a soft bag battery.

In May this year, Volkswagen hosted the National High Class and became the largest shareholder of Guoxuan's high school. It is reported that the battery supplied to the Volkswagen Gaoke will be a soft bag ternary battery. As one of the preparations, July 16th, Guoxuan's high-tech has launched an annual output of 30,000 tons of high-niobi three-yuan positive material project, which is proposed to be used in the production of a three-way soft bag battery.

On July 18, the person in charge of Wanxiang 123 said: "It has been fixed in April this year. In 2021 Q4 will start supplying to the Volkswagen. "Wanjin 123 is the company that produces soft-package batteries, the public's super billions of orders, also facing soft bag batteries.

On July 30, the news, according to Yaqi Lithium, can invest in feedback, Yiqi lithium can supply the battery of Daimler, modern Kia, Xiaopeng Automobile and other host plants, but also a soft bag battery. In addition, billioni lithium has received the designated letter of BMW Brilliance, does not exclude the supply of the supply of the BMW, is also the possibility of a soft bag battery. On August 3, the Hengda Motor Group held an announcement, and its six new energy cars were unveiled.

Waiting for new energy auto output, Evergrande subsidiary card to new energy battery to enter the battery supply chain basically no suspense. Since Ka's new energy is a company that produces a soft-box battery, then, Evergrande new energy car future supporting soft bag battery has a departure. In addition, the Yuanjing AESC has built 20GWH soft bag battery projects built in Jiangsu, my country, and the first phase will also put production in the fourth quarter of 2020.

LG Chemical In 2018, he had a 32GWH power lithium battery factory in Jiangsu Nanjing, which is mainly carried out in production of soft bag power lithium batteries. Baochong New Energy launches soft bag battery CTP method market has demand, driving technology has innovation. In order to achieve the purpose of this, the recent news shows that Baomi's battery company Baochong New Energy launched a soft bag battery technology solution, which is likely to be a soft-package battery method based on a CTP structure.

According to the description of Baochong new energy, its soft bag battery CTP method has the same place as the Ningde Times, BYD, and Tesla's Pack method, and is different. From the overall view, Baochuang new energy soft bag CTP method is not directly from Cell to PACK, which is similar to the CTP method of Ningde Times. From the angle of the module, the Baochuang new energy soft bag CTP method is a plurality of modules along the body width direction, forming a Pack.

This is a little similar to the CTP method of Tesra Model3, but in different, Tesla's module is placed in a length of the body, and the module in Baoli patented is placed in the width direction of the body. Figure: Teslamodel3pack method Compares from the battery Pack method, the battery of the Baochuang new energy soft bag CTP method is the width of the entire battery pack, which is similar to BYD's blade battery. However, in different than the BYD blade battery, the long battery of the treasure battery is not a separate long battery, but is formed by a plurality of batches.

Photo: Baochuang new energy long battery compares to the blade battery in series, Baochong New Energy Soft Pack CTP method is connected between the small electrical cells, and uses a pole protective shell. The biggest advantage of this structure is that after the battery is long, the end plate portion of the six-faced surface of the traditional module is either becomes longer, either part (important the bottom end plate), and saves the traditional module. A large amount of Busbar and partial module accessories, so the spatial utilization of the entire battery pack is increased, weight reduction, and lower the cost of battery packs.

As for how much the specific space utilization is increased, and how much is reduced, it is low, and there is no data release. In terms of hot security, Baochuang new energy places a cold plate and thermally conductive glue outside each of the cell stacks, and the thermal management unit is not against a large module, but reduces the battery stack. In the traditional soft bag battery module, it is generally 12 batter stacks, and Baochuang new energy is due to the series long battles, each of which is only 3 batches of cells, which is relatively hot.

Better. Summary: Similar to the starting point of the square battery CTP method, the soft bag CTP method is also to reduce weight and reduce costs, and improve the component efficiency. However, as a new thing, the strength problem of soft bag CTP solution, also needs to see the market inspection.
