High-Current, High-Voltage DC Switching White Paper

Electric vehicles and the corresponding infrastructure are an excellent chance for modern society to reduce CO2 emissions and improve air quality. Especially the development of high-capacity batteries was a barrier for electric vehicles in the past. While motors and inverters are a mature technology, batteries are the challenge to address. In recent years, we have seen a development of high-voltage lithium-ion batteries that have a capacity that is high enough to compete with traditional internal combustion engines.
