For pure electric vehicles, the role of power battery is very important. According to the cost analysis, at present, the power battery carried by pure electric vehicles accounts for about 30%~40% of the production cost. With the continuous development in recent years, the technical level of power batteries is also steadily improving. At the 20 19 Frankfurt International Auto Show, the battery manufacturer Contemporary Ampere Technology Co., Ltd. launched the CTP highly integrated power battery development platform. So what is the CTP technology of power battery? In fact, to put it simply, CTP technology saves the assembly of battery modules and directly integrates the battery cells into the battery pack, which can improve the utilization rate of power batteries. According to the introduction of contemporary Amperex Technology Co., Ltd., the volume utilization rate of CTP battery pack is increased by about 15%~20%, the number of parts is reduced by about 40%, and the production efficiency is increased by about 50%. For power batteries, this means that the energy density can be increased and the production cost can be reduced. Under the influence of the current declining subsidies, the reduction of production costs can reduce the terminal selling price of vehicles to a certain extent, thus improving competitiveness. So now many OEMs and battery factories are speeding up the improvement of battery production technology, looking for new materials to improve battery energy density and reduce production costs. The CTP technology of power battery has changed the production process, and there is no innovation in materials, which is similar to BYD's upcoming super lithium iron phosphate battery. So from this point of view, although this method can increase the energy density to a certain extent, the space is limited. However, although there is no obvious innovation in materials, it improves energy density, reduces production cost and increases market competitiveness. Therefore, many car companies have begun to develop CTP technology, including honeycomb energy. Therefore, in the short term, CTP technology of power battery will gradually become one of the trends. But in the long run, material innovation is still needed to solve the real problem of low energy density and stability. At present, the power battery technology is developing rapidly, and the power battery technology is constantly improving. At the 20 19 Frankfurt International Auto Show, Contemporary Ampere Technology Co., Ltd., a power battery company, launched a brand-new CTP highly integrated power battery development platform. What is CTP technology of power battery? In short, CTP technology of power battery is to integrate the battery directly into the battery pack. For example, it is like a page of a book. The words on the front and back are different, but they are all on a piece of paper. Similarly, the CTP technology of power battery is the same. Power battery is more integrated, and this technology can save battery assembly to some extent, thus saving costs. For example, take the CTP technology of power battery of Contemporary Ampere Technology Co., Ltd. as an example. The CTP technology of power battery of contemporary Anpu Technology Co., Ltd. directly connects a large number of batteries in series and parallel by omitting modules. From the effect point of view, this technology can save the use of parts and greatly improve the space utilization rate, which is also a way to reduce the total weight of the battery pack, and this practice can greatly improve the energy density of the battery. At the same time, CTP technology also has a big advantage, it can remove the template of power battery, and can directly install the battery module on the whole vehicle through the sleeve or the mounting beam through the fixing parts. This method not only realizes the lightweight of the battery pack, but also improves the connection strength of the battery pack in the whole vehicle. This can not only optimize the utilization space of the battery pack, but also improve the energy density and reduce the cost. It is very suitable for use on standard electrical boxes, and it is very helpful for car companies and battery companies to reduce manufacturing costs. CTP technology of power battery is developing faster and faster, and there will be various types of electric vehicles in the future. @20 19
