Charger sets new standard for supporting high voltage systems

Pratt & Whitney Canada has announced the development of an advanced mobile charging unit (MCU) capable of charging high-power batteries at up to 1,500 volts, making it compatible with Megawatt Charging System standards the industry is advancing for high voltage power applications. The MCU was developed in collaboration with the National Research Council (NRC) of Canada and the Innovative Vehicle Institute (IVI) as part of the RTX hybrid-electric flight demonstrator project.

The NRC focused on the hardware design, assembly, testing and delivery of two charger units, which will be used on the hybrid-electric flight demonstrator project. The charger’s bidirectional capability enables it to both charge and discharge batteries, which creates opportunities to recycle unused energy back into the electrical grid.

Pratt & Whitney Canada continues to progress in testing the propulsion system for the RTX hybrid-electric demonstrator, which targets a 30 percent improvement in fuel efficiency and reduced CO2 emissions compared to today’s most advanced regional turboprops. In 2024, the propulsion system will be linked to batteries developed by H55 S.A., which will be charged using the new charger. Hybrid-electric propulsion is a critical component of RTX’s strategy for enabling more sustainable aviation and supporting the industry’s goal of reaching net-zero CO2 emissions by 2050.
