Study on the Efficiency of ISG Driving System for Hybrid Power Bus

Abstract:

Hybrid power bus is composed of the ISG driving system and diesel engine. The ISG driving system is integrated the generator and starter. In the rule of matching the ISG motor and diesel engine, the way to simulate ISG drive system efficiency was put out. Using this method, the working process of hybrid drive system which is made by permanent magnet synchronous motor and YC6105 diesel engine has been simulated. The ISG drive system efficiency in different input voltages was analyzed, the result shows that in the rated speed ISG drive system is in high efficiency, when the speed is higher than rated speed the efficiency of drive system is decline. However, the efficiency is still in the higher range. The maximum power and torque of the ISG increase when input voltage is rising in the same speed. The ISG driving system efficiency is the same trend in different input voltage. According to bus city running condition, the torque and maximum speed of ISG drive motor can be satisfy to the requirements of city bus.
