Abstract
Because of low battery endurance of the current electric vehicles and there are not many charging stations, we try to improve the situation when batteries run out and the driver needs backup power during driving. A microturbine generator system is designed in this research, supplying power to charge the batteries of BEVs under this situation. As a result, BEVs are able to have better cruising range. Previous research experiences are continued, using a smaller turbo engine as the power source. Frame systems are designed based on the characteristics of the engine, and a small motor is used as a generator to generate electricity. According to early development experiences, the generator has some problems including overheating and misalignment of the shafts. Therefore, a device is designed to help cooling the generator, and appropriate connection devices are chosen based on the characteristics of the engine and the generator. Rectification tools are then used to rectify the misalignment of the shafts. Some methods were found to reduce the noise when the turbine engine was in operation. In addition to using the noise elimination materials to package the system, a muffler is also used to test whether it can further reduce the noise. As for the experiment, we tested the performance of the microturbine generator system. In noise test, suitable standards are found to measure different noise data of the system to test the effects of the noise reduction.
