For several years, EV manufacturing has barely exceeded 1%. Since then, many OEMs have turned to electrification due to government subsidies. That figure will rise from 11% in 2020 to 62% in 2030, with global sales reaching 63 million vehicles, according to Credit Suisse Global Automotive Research. Nearly half of them, 29 million, are expected to be fully electrified. Vicor's vice president of global automotive business development, Patrick Wadden, said in an interview that with significant investment in electrification, powertrain technology will play a key role in addressing powertrain efficiency. Volvo claims that by 2025, 50% of their cars will be electric and the rest will be hybrids. Ford, General Motors and Chrysler will invest more than $50 billion by 2030. This year's new car is estimated to be higher than last year. By 2030, of the 63 million xEV vehicles, we expect BEVs to account for 29 million, or 45% of the total xEV fleet. Internal combustion engine vehicle production could fall from 97% in 2020 to 10% in 2040," Wadden said. Some of the most popular models, like the GM Hummer, the new Ford Mach E (the electric Mustang), and the now-iconic F150 light truck, are going electrified (Lightning). The new car has improved fast charging technology, reducing maintenance and repair costs. Electric vehicle electricity demand grows up to 20 times The power output of an internal combustion engine vehicle is typically between 600W and 3kW. Electric vehicles, such as EVs, HEVs, and PHEVs (xEVs), require power levels of 3 to 60 kW, which are 5 to 20 times more than conventional vehicles. This growth is a big problem for power experts working on optimizing distribution networks (PDNs). Wadden emphasizes the need for a lightweight and compact system that is flexible enough to scale and reuse power components across the fleet to address these issues. Power levels must increase, powertrain size and weight must be reduced, and thermal management and reusability must be improved. OEMs are putting a lot of effort into improving their PDNs. They are investing millions of dollars in R&D for electrification. They are always innovating and coming up with innovative technologies. The automotive industry is rapidly developing 48-volt power technology, which is used in all-electric, hybrid, and mild-hybrid vehicles. Advantages of Automotive Modularity OEMs must pack as much power as possible into a small space, whether it's a fast sports car, a light truck or a family sedan. "Cars need compact and efficient power solutions," Warden said. To achieve full fleet electrification, OEMs must be able to reuse designs across multiple platforms to reduce time-to-market. Many automaker vehicles use the same platform, and easy power scaling is critical for adjusting power between sedans, minivans, SUVs, and other vehicles that share the same platform. The total weight of the vehicle affects performance, especially battery life. Vicor's 98% efficient bus converter module (BCM6135) can be easily implemented with EMI filtering, simplified cooling structure and a 25kg 48V battery replacement box. Measuring 61 x 35 x 7mm, the high-density power module converts primary cells from 400 to 800V to 48V, delivering over 2kW of power with >4.3kW/in3 power density.

The Dragon Boat Festival, also known as the Duanyang Festival, the Dragon Boat Festival, the Chongwu Festival, and the Tianzhong Festival, is a folk festival that integrates worshiping gods and ancestors, praying for blessings and warding off evil spirits, celebrating entertainment and eating. The lunar date is fixed on the fifth day of the fifth lunar month. The Dragon Boat Festival, the Spring Festival, the Qingming Festival and the Mid-Autumn Festival are known as the four traditional festivals in China. The Dragon Boat Festival originated from the worship of natural celestial phenomena and evolved from the sacrifice of dragons in ancient times. On the Midsummer Dragon Boat Festival, Canglong Qisu flew up to the center of the south, and was in the most "righteous" position throughout the year, just like the fifth line of "Book of Changes Qian Gua": "The flying dragon is in the sky". The Dragon Boat Festival is the auspicious day of "Flying Dragons in the Sky", and the culture of dragons and dragon boats runs through the inheritance history of the Dragon Boat Festival. The Dragon Boat Festival is a traditional cultural festival popular in China and other countries in the cultural circle of Chinese characters. [139] Legend has it that Qu Yuan, a poet of Chu State during the Warring States Period, committed suicide by jumping on the Miluo River on the fifth day of the fifth lunar month. Later generations also regarded the Dragon Boat Festival as a festival to commemorate Qu Yuan; In memory of Wu Zixu, Cao E and Jie Zitui. The origin of the Dragon Boat Festival covers the ancient astrological culture, humanistic philosophy and other aspects, and contains profound and rich cultural connotations. In the inheritance and development, it is mixed with a variety of folk customs. Due to different regional cultures, there are customs and details in different places. difference As a traditional Chinese festival, all walks of life will have a holiday. From June 03 to June 05, our circuit board factory will have a three-day holiday. The main customs and habits of the Dragon Boat Festival include racing dragon boats, eating zongzi, picking herbs, hanging wormwood and calamus, worshiping gods and ancestors, putting paper kites, drinking Pu wine, realgar wine, cinnabar wine, playing polo, dancing Zhongkui, fighting grass, etc. Among them, dragon boat racing and eating zongzi are the most important and iconic customs. During this period, the number of trips around the country increased.
