摘要
针对电动自行车新国标实施的新形势,着力解决以锂电池作为动力能源的电动自行车的安全问题,在分析锂电池安全工作因素基础上,采用在锂电池盒内部植入数据监控系统的方法,获取锂电池内部的电压、温度等数据,并监测其是否浸水和侧翻的状态,获取其经纬度等数据,将这些数据通过NB-IoT网络实时传输至云平台。一旦某些数据超过告警阈值,电动车企业和用户均能及时收到预警,以达到及时规避风险的目的。实践表明,该系统保证了行车安全。
With the new situation of the implementation of the new national standard for electric bicycles,in order to solve the safety problems of electric bicycles using lithium batteries as power sources,based on the analysis of the safety factors of lithium batteries,a data collection system is designed inside the lithium battery pack.The lithium battery internal voltage,temperature,the status of monitoring whether it is submerged and rollover,and longitude and latitude dataare transmitted to the cloud platform in real time by NB⁃IoT network.Once certain data exceeds the alarm threshold,electric bicycles companies and users can receive early warnings in time to achieve the purpose of avoiding risks.It is ensured driving safety.
