A hybrid vehicle drive system for a vehicle includes a first prime mover, a first prime mover driven transmission, and a rechargeable power source. The hybrid vehicle drive system further includes an interface between the transmission and the prime mover for coupling to an electric motor. The electric motor can be in direct or indirect mechanical communication with a hydraulic pump. The electric motor can receive power from the prime mover driven transmission through the interface.

1. A hybrid vehicle drive system for use with a first prime mover and a first transmission driven by the first prime mover, the system comprising: a second prime mover coupled to a rechargeable energy source; anda PTO interface, wherein the first prime mover is configured to provide power through the PTO interface to the second prime mover to operate the second prime mover, and the second prime mover is configured to provide power to a drive shaft through the PTO interface,wherein an electrical control system monitors torque of the second prime mover and the first prime mover to ensure a turbine torque limit associated with the first transmission is not exceeded, andwherein the second prime mover is configured to provide additional power to the drive shaft when the first prime mover provides power to the drive shaft through the transmission. 2. The system according to claim 1, wherein the electrical control system monitors the torque of the first prime mover by monitoring input torque after multiplication by a torque converter. 3. The system according to claim 1, wherein the electrical control system monitors power of the second prime mover and the first prime mover to ensure the turbine power limit is not exceeded. 4. The system according to claim 1, wherein an accessory is coupled to the second prime mover and a torque of the accessory is monitored to ensure the turbine torque limit is not exceeded. 5. The system according to claim 4, wherein the electrical control system sums the torque of the first prime mover, the second prime mover, and the accessory. 6. The system according to claim 1, wherein the electrical control system ensures the torque limits of other components in the first transmission are not exceeded. 7. The system according to claim 1, wherein the second prime mover is also configured to provide sole power to the drive shaft when no power is provided by the first prime mover to the drive shaft through the transmission. 8. The system according to claim 1, further comprising at least one more PTO interface configured to channel power to the drive shaft through the transmission. 9. A hybrid vehicle drive system for use with a first prime mover and a first transmission driven by the first prime mover, the system comprising: a second prime mover coupled to a rechargeable energy source;a PTO interface, wherein the first prime mover is configured to provide power through the PTO interface to the second prime mover to operate the second prime mover, and the second prime mover is configured to provide power to a drive shaft through the PTO interface; andan electrical control system configured to monitor torque of the second prime mover and the first prime mover to ensure a turbine torque limit associated with the first transmission is not exceeded,wherein the second prime mover is configured to provide additional power to the rechargeable energy source by using continuous power from the first prime mover when the first prime mover provides power to the drive shaft through the transmission, wherein the second prime mover is configured to provide additional power to the drive shaft when the first prime mover provides power to the drive shaft through the transmission. 10. The system according to claim 9, wherein the electrical control system monitors the torque of the first prime mover by monitoring input torque after multiplication by a torque converter. 11. The system according to claim 9, wherein the electrical control system monitors power of the second prime mover and the first prime mover to ensure the turbine power limit is not exceeded. 12. The system according to claim 9, wherein an accessory is coupled to the second prime mover and a torque of the accessory is monitored to ensure the turbine torque limit is not exceeded. 13. The system according to claim 12, wherein the electrical control system sums the torque of the first prime mover, the second prime mover, and the accessory. 14. The system according to claim 9, wherein the second prime mover is configured to provide the additional power to the rechargeable energy source by using the continuous power from the first prime mover when the first prime mover provides power to the transmission while the vehicle is driving, the driving including periods of time when the vehicle is in motion and temporarily at rest. 15. The system according to claim 9, wherein the second prime mover is configured to provide the additional power to the rechargeable energy source by using the continuous power from the first prime mover when the first prime mover provides power to the transmission while the vehicle is at temporarily at rest with a brake pedal depressed. 16. A hybrid vehicle drive system for use with a first prime mover and a first transmission driven by the first prime mover, wherein the first prime mover is an internal combustion engine, the system comprising: a second prime mover coupled to a rechargeable energy source, wherein the second prime mover is an electric motor;a PTO interface, wherein the first prime mover is configured to provide power through the PTO interface to the second prime mover to operate the second prime mover, and the second prime mover is configured to provide power to a drive shaft through the PTO interface; andan electrical control system configured to monitor torque of the second prime mover and the first prime mover to ensure a turbine torque limit associated with the first transmission is not exceeded,wherein the second prime mover is configured to provide additional power to the drive shaft through the PTO interface when the first prime mover provides power to the drive shaft, provide power to the rechargeable energy source, and directly drive an accessory. 17. The system according to claim 16, wherein the accessory is a hydraulic pump. 18. The system according to claim 16, wherein the electric control system is configured to monitor the torque of the second prime mover and the first prime mover to ensure a power take off drive gear rating associated with the first transmission is not exceeded.
