Hitachi supplies EV inverter for Audi e-tron

by Autocar Pro News Desk , 18 May 2019


The Audi e-tron's electric charging flap integrates a connection for AC and DC charging. A steady green light means charging is complete.

Hitachi Automotive Systems' electric vehicle (EV) inverter has been adopted by Audi for its first mass production EV, the e-tron, which went on sale in Europe in March this year.

With tightened environmental regulations around the world, many countries are driving for greater adoption of electric vehicles. This has led to the demand for more efficient and higher-output electric motors, inverters, and other electric powertrain systems that will contribute to high- performance EVs.

The Hitachi Automotive Systems' inverter adopted by Audi was specifically developed and designed for EVs, and provides high-power density output that helps to maximise motor performance. Specifically, this inverter is equipped with a compact, high-efficiency power module with double-sided cooling and a built-in next-generation insulated-gate bipolar transistor (IGBT). The power density output of this inverter has been increased 160 percent compared to the previous generation of inverters.

The Audi e-tron is a full-sized SUV equipped with dual electric motors and an electronic all-wheel drive system that provides superior driving performance. Hitachi Automotive Systems provides the inverters that support the electric powertrain.

The inverter used in the Audi e-tron will be on display at the Automotive Engineering Exposition 2019 Yokohama, hosted by the Society of Automotive Engineers of Japan, at Pacifico Yokohama from Wednesday, May 22 until Friday, May 24.
