基于道路压力发电的新能源汽车快速充电桩的研发

Research and development of fast charging pile for new energy vehicles based on road pressure power generation

随着国家推行新能源汽车,目前电动汽车充电仍然以化石燃料燃烧为主,存在能耗大、不经济环保的缺点;同时城市道路和高速公路等道路上每天的交通量都很大,路面不断受到车轮碾压,道路会产生巨大的形变,将这些机械能收集起来便可以为电动汽车充电。根据汽车需求用电要求,创新性研究设计了一套由内部采用高导磁硅钢片材料的发电机和直流充电桩联合作用转换利用道路能量的新能源充电桩。本装置利用汽车碾压使动子切割永磁体产生的磁场产生电能,经过整流、滤波、稳压、调幅等技术将收集的电能转换为可供汽车快速充电的电能大小,采用超级电容和蓄电池混合储能,不但保证汽车充电需求,还可减少化石能源的燃烧以及回避风光发电的地域限制。

With the implementation of new energy vehicles in China, the current electric vehicle charging is still mainly based on fossil fuel combustion, which has the disadvantages of large energy consumption, uneconomical and environmental protection. At the same time, the traffic volume on urban roads and expressways is very large every day. The road surface is continuously rolled by wheels, which will cause huge deformation. Collecting these mechanical energy can charge electric vehicles. According to the electric demand of automobile, a set of new energy charging pile is designed, which is composed of high magnetic conductivity silicon steel sheet generator and DC charging pile. The device uses the magnetic field generated by the motor to cut the permanent magnet to generate electric energy. Through rectification, filtering, voltage stabilization, amplitude modulation and other technologies, the collected electric energy is converted into the electric energy for rapid charging of the automobile. The hybrid energy storage of super capacitor and battery is used to effectively ensure the charging demand of the vehicle, while reducing the burning of fossil energy and avoiding the place of wind and solar power generation Domain restrictions.
