1. A vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, and a rechargeable energy source, the vehicle drive system comprising:
- a power take-off (PTO) connected to the first prime mover configured to rotate a PTO interface at a first speed;
a gear box connected to the PTO at the PTO interface and configured to rotate at a second speed at an upper output interface when the PTO interface rotates at the first speed, wherein the second speed is higher than the first speed; and
an electric motor in direct or indirect mechanical communication with the first prime mover driven transmission through the PTO and the gear box, wherein the electric motor can receive power from the first prime mover driven transmission via the upper output interface of the gear box.
