According to statistics, sales of new energy vehicles rose from 13,000 units in 2012 to 3.521 million units in 2021 and 4.567 million units as of September 2022. The main function of an on-board charger (OBC) is to convert an AC voltage input to a DC voltage output to suit the current and voltage levels of the battery pack.
In new energy vehicle applications, capacitor is a key component in energy control, power management, power inverter, and DC AC conversion. The reliability life of the capacitor also determines the life of the OBC charger. At present, three types of capacitors are mainly used in new energy vehicle OBC - DC filtering, DC support capacitance, and 1GBT absorption, and aluminum electrolytic capacitors are essential components in these applications.
With the update and iteration of on-board OBC technology, the driving platform in the 800V battery system has been upgraded to 1000v or 1200V; The high-voltage platform architecture is the basis for fast charging of new energy vehicles, and at the same time, this puts forward extremely high requirements for aluminum electrolytic capacitors. Aluminum electrolytic capacitors have always been tough in the industry such as high technical threshold and low capacity density in the field of ultra-high voltage.
Shanghai Yongming Electronics Co., Ltd. adheres to the corporate culture of capacitor application - Call Ymin for Any Capacitors Solutions, actively explores the difficulties of users in capacitor applications, and develops and solves the problems of aluminum electrolytic capacitors in ultra-high voltage and high capacity density, and launches ultra-high voltage series horn products, which increase the withstand voltage capacity by 20% and the capacity density by more than 30% under the same size. Yongming’s ultra-high voltage capacitors have been deeply cultivated for many years and were stably used in automotive OBC, new energy charging piles, and photovoltaic inverters, industrial robots and other fields, which is in line with the new energy era and committed to capacitor quality and efficiency, customer demand as the lead. We also pursue scientific and technological development as the law. Yongming will always keep pace with new energy era unified progress.
