Protecting fast EV charging stations
Several standards dictate safety measures that fast charging stations must employ. Philippe Di Fulvio, Littelfuse, Inc. An estimated 5.5 million electric vehicles (EVs) were on the road in 2020. By 2025, the expectation is that over 24 million EVs will be in use. A significant limitation to wider EV adoption is the public charging infrastructure […]
Battery pack protection keeps EVs on the road
A few best practices for handling transients and over-currents help make electronic drivetrains more reliable. James Colby • Littelfuse, Inc. Automotive market analysts predict that by 2025, high-end vehicles will contain more than $6,000 in electronic components. Most of these advanced electronics will be in the growing number of electric vehicles (EVs). To ensure robust, […]
SMD fuses optimized for solar roofing apps
Littelfuse, Inc. announced the 400PV Fuse series, a 2410 size, surface mount design (SMD) circuit protection component that offers low resistance for photovoltaic (PV) applications.
