ITEM                              SPECIFICATION REQUIRED                                     VARIATION

1. The Propulsion System       The Propulsion System consists of the Traction Motor, the Traction Inverter, the
                               Battery System, the Generator-Set, and the Electronic Controller. The Traction Motor
                               is the only power source that provides tractive power to move the bus. The Traction
                               Inverter energizes the Traction Motor at the proper Torque level commanded by the
                               bus operator. The Battery System provides peak power to the Traction Inverter for
                               intermittent power demand to operate the bus in hybrid mode. It also provide all the
                               power need in Zero-Emission mode. The Generator-Set provides the average power
                               need to support extended range operation. It is powered by a diesel engine. The
                               electronic controller serves as interface between the bus operator and the Propulsion
                               System. It also coordinate the operations of the components in the propulsion system
                               for optimum energy utilization.

1a. Traction Motor             The Traction Motor shall have a minimum output of 150 hp on a continuous duty
                               basis at 40 degrees Celsius ambient temperature per National Electric Manufacture

                               for 1 minute out of every 10 minutes. It has 300 hp peak power rating. The motor
                               maximum speed shall not exceed 3000 RPM, which matches the speed range of a
                               diesel engine for ease of mechanical interface and hence high efficiency. The

                               Standard testing method. The Inverter shall have 150% overload capability for 1
                               minute out of every 10 minutes. The Inverter shall be of closed-loop Flux Vector
