The proper adjustment of parameters and dynamic characteristics of energy and power sources is very important in designing process of hybrid drive. This is evident that both internal and external combustion thermal engines (gasoline, diesel, microturbine or fuel cell) can be the energy source (primary). The electrochemical battery or supercapacitor can be the power source (secondary). Presently, from the practical (technical and economical) point of view it is possible to apply thermal engines and electrochemical batteries as energy and power sources respectively. It is necessary to test by modeling and simulation of dynamic feature of hybrid drive sources cooperation to obtain the proper adjusting of driving properties. The designing and controlling of the torque and angular speed distribution by the Torque Transmission Unit, which most often is a mechanic-electric controllable CVT, are essential issues. The basic of the proposed in paper method is dynamic determination of the simultaneous alteration of the operation point of the thermal engine and a traction motor, which is the controllable component of the Torque Transmission Unit. It is necessary to emphasize that minimizing of the thermal engine fuel consumption and the state of charge (SOC) of electrochemical battery, depending on the thermal engine and electrochemical battery energy proportion in hybrid drives is the assessment factor of quality to make the proper adjustment. Dynamic testing of the components torque and angular speed distribution and its effectiveness in hybrid drives allows to define and minimize the internal losses depended in significant way on the drive architecture and its energy flow proper control.
