EV Industry Facing Bottleneck Challenges

Nolan Johnson talks with Eduardo Benmayor, general manager at Aismalibar, about materials challenges facing the powertrain portion of the automotive EV industry. Eduardo also speaks about what he sees as the biggest challenge facing EVs—infrastructure.

Nolan Johnson: Aismalibar is in a position to have a unique perspective on some of the dynamics in automotive production. What are you seeing as major trends in automotive currently?

Eduardo Benmayor: As you may know, in the automotive industry the percentage of electronics inside the car is growing every year, so that’s been on the table for many, many years. Right now, we see three main families of electronics inside the car. The first is related to securities, radars, detectors and all kinds of cameras. Then, we have all the power electronics, which Aismalibar is focused on: AC/DC converters, DC/DC converters, on-board charging stations or external charging stations, all related to high power and a lot of heat. The third family is telecommunications and communications of the car with external devices and the internet, which is a completely different area of the electronics business.

Our business is mainly focused on how the electronics engineers are designing the heat dissipation and dielectric strength around the electronic chargers inside the car. This drives them to a lot of different problems, and all these problems are viewed with different solutions. We don’t see a clear trend in the automotive industry; sometimes the big players go in one direction with IGBT technologies, others go to the MOSFET technologies, while others go with a completely different technology. There is not a standard trend, in general.
