摘要：
This paper reports the establishment of a piezoelectric vibration energy harvester for electric vehicle (EV) applications. Finite element analysis results, which agree experimental outcome well, have demonstrated that the piezoelectric vibrator can produce 1 V DC electric signal under 2 mm amplitude mechanical vibration at lower frequency. The energy harvester comprising two piezoelectric vibrators connected in series charged a Ni-MH secondary battery from 1.17 V to 1.24 V. It is verified that this piezoelectric energy harvester can be used in EVs and will potentially improve the energy use efficiency and performance of EVs.
