The global power battery giant has mastered the core technology of power batteries
Global electric cars continue to heat up, and manufacturers are scrambling to invest in research and development. As its core, what are the drivers of the power battery technology of mainstream electric cars and the most iconic electric cars around the world? What are the core technologies of power batteries?
panasonic
Panasonic is the exclusive lithium-ion battery supplier for tesla electric cars and is also the world‘s leading battery maker. Tesla‘s battery components are relatively cheap (though cheaper lithium-ion batteries can be found, but the power and thermal properties are not good). Together the two sides are the construction of super for pure electric vehicle battery factory, battery technology and share large-scale production cost through ascension to further reduce the overall cost of the battery. The tesla MODEL S for the 18650 type products of panasonic batteries, battery capacity up to 85 KWH, actually the battery pack consists of 8142 3.4 ampere hour battery, Japan‘s sumitomo chemical for panasonic heat-resisting membrane used in the production of lithium batteries.
AESC
AESC is a joint venture company of nissan and Japan‘s NEC, nissan Leaf (Leaf) adopted AESC battery, the battery unit in Japan factory for the production, after oppama plant is assembled into a battery pack. Compared with nimh batteries, AESC lithium-ion batteries can provide nearly twice the power capacity, and its unique laminated structure, also make the volume of a lithium battery module is more light and practical. At the same time, the electrodes made from the manganese metal developed by NEC have better stability, and the chip structure helps to dissipate heat. It is reported that in the real car driving experiment, not only the safety of the battery has been verified, but also the more than 100,000 kilometers long service life.
LG chem
LG chemical information in petroleum chemical, electronic materials, such as secondary battery three career as the center, the Chevrolet Volt Volt motor is the use of South Korea‘s LG chemical research and development of ternary lithium ion batteries. The cell was designed with a laminate and 192 cell units. In order to improve the heat dissipation, a group of two layers of pressure cells are configured to make a "unit group" between these two units. The configuration USES the current T font style installed in the central channel and the back seat. LG chem also provides battery technology for the Renault Zoe electric car, Chevrolet spa, ford focus electric car, Volvo V60 and XC90T8 plug-in hybrid cars.
Samsung SDI.
Samsung SDI (China) is to point to China‘s samsung tube production department, because the display technology of liquid crystal, the career of lithium battery pack (‘ pack), samsung SDI will China market as a global car batteries on the market one of the most important market, in order to speed the development of China‘s electric car market ahead, in numerous international battery manufacturers, samsung SDI took the lead in China to build the factory specializing in the production of automobile power battery, and put into mass production.
As early as in August 2014, samsung new ring (xi ‘an) power battery co., LTD. (hereinafter referred to as "new" samsung ring) of automobile power battery project construction in xi ‘an, will become the largest production base of automobile power battery.
Completed in October 2015 samsung SDI xi ‘an factory with annual output of 40000 sets of high performance vehicle dynamics (standard) pure electric EV battery one of the most advanced production line, production line covers production car power battery unit and the module of the whole process. Formally put into production of xi ‘an factory not only to the existing international OEM supply battery, new samsung ring with dongfeng xiangyang station wagon co., LTD. Signed the new energy automobile green supply chain strategic cooperation agreement. Samsung SDI also supplies batteries to zhengzhou yutong and baic. The agreement to supply power batteries has been signed with more than 10 local commercial vehicles and car companies in China, and has begun to supply products.
John sons-saft
Johnson controls - Mr Ford (JohnsonControls - Saft) by Johnson controls and French Saft joint venture company, mainly engaged in the development and manufacture of lithium ion battery, the factory is located in France that sarkozy (Nersac). As the world‘s first lithium battery production hybrid, mercedes-benz S400 hybrid is also worth mentioning, it truly realize the "green luxury". The car was powered by a power battery from Johnson saford. Mercedes-benz S400 hybrid powered lithium ion battery has high energy density, the greater power efficiency, make the layout of the engine compartment and the main internal space remains the same, and the lighter weight can also make the vehicle easier to achieve the optimal weight distribution ratio after.
