Abstract

The energy recycle circuit fed back the energy to batteries is one of the important means to extend the travel distance of action vehicle for an electric vehicle or hybrid vehicle by driven batteries. In order to achieve energy recycle must be use, such as the motor characteristics, the principle of motor controller and design of circuit to reach the energy recycle of motor in action vehicles. Focus on the 24 V 8A 150W servo motor and its shaft coupling with a condition by magnetic brake to simulate as the analog load and adjust the brake to 0.2 Newton-meter. According to the characteristics of the motor, the principle of the motor controller and the design and energy recovery of the circuit system for discussion, that include drive control circuit of motor and based on the former to design the circuit of energy recycle circuit of motor and to feed back the energy to the driving batteries. According to the characteristics of the motor, the principle of the motor controller and the design and energy recovery of the circuit system for discussion, that include drive control circuit of motor and based on the former to design the circuit of energy recycle circuit of motor and to feed back the energy to the driving batteries. By mean of the architecture of energy recycle circuit to test the power recovery which divide into without load and without energy collector, without load and with energy collector, with load and without energy collector and with load and energy collector four cases under these conditions to investigate the power recovery analysis. For the statistics of energy, the average energy recovery power percentage by without load and without energy collector is 9.7%, the average energy recovery power percentage by without load and with energy collector is 20.5%, the average energy recovery power percentage by with load and without energy collector is 1.82%, and the average energy recovery power percentage by with load and with energy collector is 3.1%.
