When it comes to heavy-duty electric vehicles (like large trucks), the requirements are pretty high: absolutely minimal losses in the entire drivetrain, fast charging capabilities, high power ratings with high torque at low speeds and low torque at (cruising) high speeds. In addition to <em>very simple demands<\/em> like 10x more lifetime than a conventional passenger car, and reliability close to 100%.<\/p>\n<p>For all the reasons above, we are observing a shift towards higher voltages in the heavy-duty vehicles. For a given power range, higher voltages reduce the currents, which reduces losses. It also potentially enable faster charging times. Regarding torque-speed and reliability, well: it is all to explore. That is why we are here.<\/p>\n<p>We are soon starting this project under this years 2023.
