low voltage Power Generation System is a lightweight solution being used by the United States
Army for board vehicle power (OBVP) generation to their Fuel-Efficient
Ground Vehicle Demonstrator (FED). Kollmorgen says the system enables the FED Alpha vehicle to
provide 30kW of power at 28V dc, over a wide engine operating band. Kollmorgen's
low voltage power generation platform consists of flexible power electronics
that support multiple generator configurations and mild hybrid
capability. The generator system used in the FED vehicle is an in-line
ISG 28V dc, 30kW liquid cooled generator with three 10 kW air cooled power
electronics modules, which communicate on J1939 software protocol. The low
voltage platform also includes a belt driven air cooled generator that produces
30kW at 28V dc, utilizing the same controllers as the ISG system.
A simple new chemical method for repairing and recycling notoriously difficult carbon fiber composites has been developed by the Fraunhofer Institute for Applied Polymer Research. An entire component can be completely recycled, including reclaiming its expensive carbon fibers for reuse.
In today’s connected world we are seeing the beginning of connected homes, smart grids, self-driving automobiles, drones, and many other amazing devices. Out of all the soon-to-be connected devices, which device poses the greatest dangerous to its users and society?
