    Components consolidation around power systems marks EV uptake

    By Majeed Ahmad | September 10, 2017

    Volvo’s landmark announcement about ceasing the production of internal combustion engine (ICE) vehicles by 2019 negates the common perception among industry observers that electric vehicles (EVs) lack consumer interest.

    The Swedish automaker has vowed to produce only three types of electric vehicles from 2019 onward: mild electric vehicles featuring 48-volt system, Twin Engine a.k.a. plug-in hybrid electric vehicles (HEVs), and fully electric vehicles.

    Another vital sign in favor of automotive electrification comes from Taiwan where IT players are known for sensing the industry drift way ahead of time. Taiwan’s electronic manufacturers are now aggressively pursuing opportunities in electric vehicles, providing products ranging from motherboards to power modules to cooling plates.

    The U.S. component suppliers like Dana are also joining the vehicle electrification fray by developing IGBT module and battery cooling technologies. Dana has recently showcased products such as cold plates and sub-cooled loop radiators for EV and HEV power systems.

    Dana has made available a variety of EV/HEV solutions including battery cooling plates and chillers.

    The company claims that its cooling plates ensure thermal resistance to prevent IGBT chips from overheating and possible failure. These IGBT solutions also facilitate low coolant conductivity levels by minimizing contamination.

    Next, AVX, a passive components supplier, has unveiled two power film capacitors that have been specially designed for DC-link circuits between rectifiers and inverters in electric and hybrid vehicles.

    AVX’s power film capacitors protect high-power-density inverters in EVs/HEVs.

    The FHC1 and FHC2 Series capacitors work in conjunction with IGBT modules to smooth and filter current and voltage variations across the DC bus and thus prevent ripple currents from reaching back to the power source.

    The myriad of solutions built around power systems for electric and hybrid vehicles from a wide array of suppliers is another sign that winds are changing in favor of vehicle electrification. And Volvo’s pledge to say goodbye to internal combustion just affirms the rapid evolution of electrical systems in cars.
