Electrical currents in EV battery systems can flow in both directions, which can cause potentially dangerous situations during high voltage currents. As a result, contactors are used as a safety disconnection device for high voltage battery banks and DC chargers for xEV applications. However, these two applications for electric vehicles have vastly different requirements. Consequently,… Read more »

Webinar: Ultra anti-abrasion high-voltage contact plating
Virtually every major car manufacturer around the world is shifting its strategy and placing more emphasis on its battery-powered, hybrid, and plug-in-hybrid vehicle product lines. Consumers want their EVs to recharge more quickly, drive longer distances between charges, and last longer. But electrified vehicles and their systems, including high-powered charging (among others), are extremely sophisticated…. Read more »
Moving to higher voltages in EVs: The implications on capacitor selection
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 »
