Exro’s technology platform can be reconfigured as a motor (Variable Input Electrical Motor) in addition to being a variable generator (VIEG). For example, the algorithm that optimizes the machine’s output as a wind turbine generator would match the machine’s output to the available wind energy in real time, while the algorithm used in an electric car application would reconfigure both the machine’s relative output and its circuitry in a way that would is more efficient through the full range of braking (as a generator) and accelerating (as a motor).

Our controller technology is ideal for operating electric vehicles which need to shift really quickly on the fly. Currently, many EV’s are limited by their inability to shift quickly in a range of rpms, leaving their motors to only be efficient in a very narrow band. The VIEM’s unique geometry, on the other hand, allows for more efficient capture and conversion of electrical energy into torque in a wide range of rpms. Exro envisions applications including golf carts and scooters.
