快递三轮车光伏供电系统设计

近年来,快递产业发展迅速,快递三轮车保有量大幅提升。现有快递三轮车在使用中存在续航里程短和蓄电池常常处于低电量状态导致使用寿命大幅度下降的问题。针对上述问题京东物流和汉能集团在快递三轮车车棚顶部安装光伏组件为蓄电池提供电能,但安装的光伏组件容量小,效果一般。该设计在三轮车车棚的顶部和3个侧面都安装光伏组件,且倾斜角可以根据光照角度调整,同时根据快递三轮车行驶过程中,光照容易受到建筑物、树荫等的遮挡,导致光照快速变化的情况,提出改进的扰动观察算法的最大功率点追踪,提高光伏组件的发电效率,最终有效地提高快递三轮车的续航能力,同时提高蓄电池的使用寿命。

In recent years,the express delivery industry has developed rapidly,and the number of express tricycles has increased significantly.Existing express tricycles have the problems of short cruising range and low battery charge status during use,which leads to a significant decrease in service life.Competing for the above-mentioned problems,JD Logistics and Hanergy Group installed photovoltaic modules on the top of the express tricycle carport to provide power to the battery,but the installed photovoltaic modules have a small capacity and the effect is mediocre.In this design,photovoltaic modules are installed on the top and three sides of the tricycle shed,and the inclination angle can be adjusted according to the illumination angle.At the same time,according to the fact that the light is easily obscured by buildings and trees during the driving process of the express tricycle,which leads to the rapid change of light,an improved disturbance observation algorithm is proposed to track the maximum power point,which improves the power generation efficiency of the photovoltaic module.Finally,it can effectively improve the service life of the express tricycle and improve the service life of the battery at the same time.
