Electric vehicle industry fuels trend for high-voltage automotive relays

摘要

As the shift to electric vehicles or EVs continues, driven bya rise in awareness of the need for environmental protection, a change is happening in the automotive relay sector. Conventional types have taken a back seat as attention turns to development of the high-voltage variants used in electric cars, two-, three and four-wheelers, buses and trucks. Such components have a rated voltage of 370VDC or even 576VDC, high load and shock resistance, and enhanced rupture capability, in addition to being lightweight. In China, where there are national and local subsidies for buying EVs, this trend promises a growth rate as high as 41 percent for the high-voltage relay market in 2020. The estimated value is $597 million over that of 2019, according to Zhiyan Consulting. In contrast, the mainstream low-voltage category is expected to post an increase of something over 7 percent. In export markets, automotive relays, which posted an overall annual increase of about 10 percent in recent years, will remain at this rate forthe next two years.
