BMW is building EVs and legacy gas-burners on the same production lines—and it seems to be working


Legacy automakers, keen to make an “orderly transition” to EVs, have embraced all kinds of half-measures, from PHEVs to awkward ICE-to-EV conversions to pick-your-powertrain production lines. Conventional wisdom among EV advocates is that this is a mistake—industry leader Tesla and other startups have generally taken a clean-sheet approach to designing both their cars and the… Read more…

Polymer considerations for EV


Lightweight with higher temperature resistance, thermoplastics are ideal for e-mobility powertrains, Nick Flaherty reports
The push to make e-mobility designs lighter to boost range is driving significant innovation in materials. Thermoplastics are being redesigned to provide various combinations of temperature and flowability for manufacturing and plating capabilities. Read more…

Inverters


Modern inverters are including more intelligent features to work with other vehicle systems, reports Peter Donaldson
Inverters do the conceptually straightforward job of converting an electric current from DC into AC form. As such, they create an essential link between the energy storage system and the motor.
Modern inverters use solid-state semiconductor switches, connected to form combinations of half-bridges and activated by smaller switching circuits known as gate drivers, which in turn are under the control of processors that implement control logic embodied in hardware, software or both. Read more…
