Film Capacitor in New Energy Vehicles

Film Capacitor in New Energy Vehicles

New energy vehicles refer to the use of unconventional vehicle fuels as power sources. New energy vehicles include hybrid vehicles, pure electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy sources (such as high-efficiency energy storage devices )   Cars and other categories of products.

Motor, battery and motor control technologies are the three cores of new energy vehicles. The core of motor control technology is the inverter technology that requires high-efficiency motor control. The high-efficiency motor-controlled inverter technology requires   a powerful IGBT   module and a matching DC-LINK capacitor.

Technical advantages of film capacitors

Early DC-LINK film capacitors used electrolytic capacitors. With the development of   film capacitor technology,   especially the development   of   the base film technology and the use of segmentation technology for metallization, not only the volume of the film capacitor is getting smaller and smaller. The pressure level of the product is still at a considerable level. Now more and more companies use high-temperature   polypropylene film capacitors as DC-LINK capacitors. A typical example is the improvement of Toyota's RIUS model;   Representatives   are   BYD F3DM and E6, both use film capacitors as DC LINK capacitors. The filter capacitor used in the first generation   Toyota   Prius   was   an   electrolytic capacitor. From the second generation, the   film capacitor bank was used.
