Electricity Flow Analysis in the Series Hybrid System by the Charge-discharge Tester

In this study, the series hybrid electric system is recommended as suitable power systems of the motor vehicles in urban area. It is important for this system to improve the comprehensive energy efficiency when components are combined, and to evaluate it appropriately. In this report, the technique to grasp energy loss in detail that occurs when electric power flows complicatedly in the series hybrid power system has been examined and the energy efficiency of the series hybrid power system on urban driving has also been evaluated.
