Pratt & Whitney Canada (an RTX business) has developed 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 of Canada (NRC) and the Innovative Vehicle Institute (IVI) as part of the RTX hybrid-electric flight demonstrator project.
“This is the latest example of our hybrid-electric flight demonstrator project, driving collaboration and innovation within Canada’s aerospace ecosystem to enable a more sustainable future for aviation,” said Alexandre Gagnon, vice president of corporate affairs, Pratt & Whitney Canada. “High voltage, bidirectional charging systems will be critical for a growing number of electric and hybrid-electric systems including aircraft, as well as other transport applications.”
The MCU is assembled from commercially available components and can deliver up to 280kW and 1,500 volts. In collaboration with IVI, Pratt & Whitney developed a distributed control and protection strategy. 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.
