In recent years, multilayer ceramic capacitors (MLCCs) have emerged as an excellent capacitor option for the high-power electrical systems needed in electric vehicle (EVs) due to their small physical size, low inductance, and ability to operate at higher temperatures. However, engineers are facing two big challenges with MLCCs including DC bias that can cause capacitance losses of 80 to… Read more »
Sponsored by Knowles Precision Devices EV manufacturers are beginning to redesign their vehicles to make the switch from the 400 V battery systems widely used today to 800 V battery systems. Just like engineers faced challenges when moving from the standard 12 V batteries used in combustion vehicles to the higher voltage battery systems used in… Read more »
As EV-makers continue to upgrade from 400 V to 800 V systems, parts suppliers have been hustling to keep up with the new specs. Knowles Precision Devices, for example, specializes in high-voltage capacitors—it’s a market leader in multi-layer ceramic capacitors rated from about 200 V up to 12,000 V. Looking back just 10 or 15… Read more »
With high-performance electric vehicles such as the Porsche Taycan in production, and several manufacturers slated to release EVs with 800 V battery systems in 2021, using high-voltage battery systems in EVs is no longer just theoretical. The advent of higher-voltage vehicles means the decisions EV designers and OEMs must make when selecting the components used… Read more »
Sponsored by Knowles Precision Devices The worldwide electric vehicle (EV) market is exploding in demand and mainstream adoption as governments push for fuel economy improvements and automotive companies look for new market opportunities. According to Forbes, “by 2020, EVs are likely to cost the same as conventional fuel powered equivalents.” Major manufacturers – like General Motors, Toyota,… Read more »
