【摘要】：随着科技的日新月异和人们对绿色节能理念的增强,“新能源”电动汽车的发展成为大势所趋。近些年来,各国汽车行业巨头花巨资、人力和物力研究开发电动汽车,虽然取得了很多不错的成果,但是,仍有很多瓶颈问题无法突破,使现有的电动汽车整体不能和传统的燃油汽车相比,主要体现在价格高、续驶里程短、充电难、充电时间长、需要建设大量的充电站等方面,这些都成为电动汽车亟待解决的大问题。设计一个实用且安全可靠的电动汽车充电器系统,并进行投资推广,对于推动电动环保节能汽车的意义重大,这样电动汽车才可能真正普及。本文设计的公共电动汽车充电器系统使用低功耗、速度快及资源多的MCU STM32作为核心控制,使用RFID及GSM技术让整体充电桩易用和智能。多种保护措施使充电安全可靠,包括独立电流过载保护装置、充电线故障检查保护、过热保护、紧急按钮停止保护、内部供电故障保护、实时监测电动车通讯异常。最大输出32A电流,220V民用交流电,满足小区充电用户的需求。实时显示充电桩状态及RTC,充电完成后发送短信到用户手机。
[Abstract]:With the rapid development of science and technology and the enhancement of the idea of green energy saving, the development of "new energy" electric vehicle becomes the trend of the times. In recent years, the automobile industry giants of various countries have spent a lot of money, manpower and material resources on the research and development of electric vehicles. Although they have achieved many good results, there are still many bottlenecks that cannot be broken through. As a whole, the existing electric vehicles can not be compared with the traditional fuel vehicles, mainly reflected in high price, short driving mileage, difficult charging, long charging time, and the need to build a large number of charging stations, etc. All these become the big problem that electric vehicle needs to be solved urgently. It is of great significance to design a practical and safe and reliable electric vehicle charger system and invest and popularize it to promote the electric environmental protection and energy saving vehicle, so that the electric vehicle can be truly popularized. The public electric vehicle charger system designed in this paper uses MCU STM32 with low power consumption, high speed and more resources as the core control. RFID and GSM technology are used to make the whole charging pile easy to use and intelligent. Various protective measures make charging safe and reliable, including independent current overload protection, charging line fault detection protection, overheating protection, emergency button stop protection, internal power supply fault protection, real-time monitoring of electric vehicle communication anomalies. The maximum output 32A current is 220 V civil AC, which meets the needs of charging users in residential area. Real-time display of charging pile status and RTC, after the completion of charging send SMS to the user's mobile phone.
