Abstract
One embodiment relates to a hybrid vehicle drive system for a vehicle including a first prime mover, a first prime mover driven transmission, a rechargeable power source, and a PTO. The hybrid vehicle drive system further includes a hydraulic pump in direct or indirect mechanical communication with the PTO. The hybrid vehicle drive system further includes an electric motor in direct or indirect mechanical communication with the hydraulic pump. The electric motor can receive power from the prime mover driven transmission through the PTO. The hydraulic pump can receive power from the electric motor when the electric motor rotates, the electric motor using power from the rechargeable energy source, or from the prime mover driven transmission through the PTO.
