1. A power system, comprising:
- a prime mover drivingly connected to an electric motor/generator;
a first electrical energy storage device;
a second electrical energy storage device;
a first power regulator;
a second power regulator; and
power-system controls configured to selectively start the prime mover byselectively charging the first electrical energy storage device with electricity from the second electrical energy storage device by receiving electricity from the second electrical energy storage device at the first power regulator and supplying electricity from the first power regulator to the first electrical energy storage device; and
transmitting electricity from the first electrical energy storage device to the electric motor/generator via the second power regulator to operate the electric motor/generator as an electric motor to start the prime mover.

Abstract
A power system includes a prime mover drivingly connected to an electric motor/generator. The power system may also include a first electrical energy storage device and a second electrical energy storage device. The power system may further include power-system controls configured to selectively start the prime mover by selectively charging the first electrical energy storage device with electricity from the second electrical energy storage device and transmitting electricity from the first electrical energy storage device to the electric motor/generator to operate the electric motor/generator as an electric motor to start the prime mover.
