Rethink component design for electric vehicles 
Despite being first invented in the 1830s, electric vehicles (EVs) have only become commercially viable in the last decade. The global effort to reduce carbon emissions and improve air quality is increasing pressure on car manufacturers to transform their portfolios. Swedish manufacturer Volvo became the first major automaker to announce a move to an all-electric range by 2019, which has since been followed by Mercedes-Benz and the Volkswagen group.

At REO, we have used our experience of dealing with these types of components in railway traction applications to develop and integrate cutting-edge EV technology into production vehicles for some leading German automakers. To put the components through their paces, we even have our own employee e-cars and e-station.

The REO PFC Choke (CHI 412), for example, has been designed to limit the mains harmonic currents that are generated by non-linear AC power supplies, while the REO common mode choke (CHI 131) features a high performance impulse filter, which eliminates noise in the inverter that occurs due to high frequency switching.

As EVs become increasingly mainstream, it’s important that design engineers and automotive companies understand the importance of assembling their latest models with components that address power quality issues.

The components used in internal combustion vehicles have undergone a century and a half of design refinement. It is only when we have resolved the issues concerning component design that EVs will be positioned as a more sustainable alternative to petrol and diesel cars.
