A look at BMS validation testing

The battery pack is not only one of the most expensive components in an EV—it’s also incredibly complex, in some cases comprising thousands of individual cells. The tasks of preserving a battery’s efficiency, lifespan, thermal stability and safety rest upon the battery management system (BMS), an embedded controller that regulates the flow and distribution of… Read more »

EV motor shaft bearings: One of the few moving parts

CoorsTek argues that ceramic bearings are the best fit for EVs The less moving parts in a machine, the better. That’s one often-heard argument for the superiority of electric powertrains over internal combustion engines (ICEs), in which the number of moving components is dramatic. Sure, EVs have a lot of electrons moving this way and… Read more »

EMC for EVs: Understanding electromagnetic compatibility

Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »
