With more and more strict emission laws and regulations, automobile enterprises vigorously develop new energy vehicles. New energy vehicle power forms are also divided into a variety of 48V light hybrid system is one of them. Based on the market prospect of 48V light hybrid system route, Bosch Group focuses on the layout in this field. Recently, Bosch announced plans to start production of 48V batteries for automobiles at its Eisenhower plant in summer 2021. 48V light hybrid system what? Preliminary understanding refers to adding a 48V lithium battery hybrid system on the basis of 12V storage. 12V circuit is responsible for dealing with traditional electrical loads such as lighting, ignition, sound system, etc., while 48V circuit is responsible for supporting active chassis system, air conditioning compressor, regenerative braking system, etc. The vehicle equipped with 48V light hybrid system can realize the functions of dynamic energy recovery, fast start and engine assisted traction power, so as to improve the fuel economy of the vehicle and reduce exhaust emissions. Bosch predicts that the next generation of vehicles will rely heavily on the 48V system, as higher voltages are needed to generate the power needed to become the processor that controls the highly automated system. 48V light hybrid technology is used in more and more models. With BBA and other brands as representatives, (parameter | inquiry), Audi A8L, etc. earlier adopted 48V technology. Now, the new S90, V90 CC, new modern i30 and other models will also adopt 48V technology. Bosch predicts that nearly 20% of the new cars sold in the world in 2025 will be equipped with 48V system and matching batteries, and the 48V hybrid battery of Bosch will meet the needs of global automobile manufacturers. Bosch will expand its position in the 48V battery market based on its advantages in battery management. It is reported that BOSCH has begun to produce the first generation of 48V batteries in its Wuxi plant in China, and announced the development and manufacture of 48V batteries in 2019.
