摘要

由于排放技术要求不那么严格,电动两轮车和三轮车(2&;3W)产生的污染物比汽车多。世界上大约20%的注册摩托车在非洲。车辆污染是非洲死亡和健康问题的主要原因之一。交通的电气化为E2&;3W在非洲。为了评估这种转变,本研究量化了E2&;3W存在于一些非洲国家。对电动汽车初创企业、驾驶员和车主体验的调查用于确定E2&;3W的技术可行性和与汽油踏板车(p踏板车)竞争的能力。SimaPro 9.4软件和Ecoinvent 3.8数据库用于对使用电动滑板车(电动滑板车)的环境影响进行从摇篮到坟墓的分析。研究发现,非洲的E2&;与汽油版本相比,3W的市场份额为0.2%。电动踏板车的主要缺点是续航里程和电池寿命有限。平均航程和速度为50​km和50​km/h。E2&;3W对牵引电机造成损坏,是分销商最关心的问题。E2&;3W是其低运营成本和低环境影响。在南非,电动踏板车对环境的总体影响超过了电动踏板车。对人类健康有直接影响的排放量,电动踏板车明显低于电动踏板车。电池性能标准、电池交换站标准和充电站标准的缺乏对进口电动踏板车的质量产生了负面影响。非洲国家需要实施电动汽车标准和电池回收政策,并建立电动汽车培训和研究中心。

Feasibility of electric two and three-wheelers in Africa

Due to the less stringent emission technology requirement, motorized two and three-wheelers (2&3W) generate more pollutants than cars. About 20% of the world's registered motorcycles are known to be in Africa. Vehicle pollution is one of the major causes of death and health problems in Africa. The electrification of transportation provides an opportunity for E2&3W in Africa. To assess this transition, this study quantifies the number of E2&3W present in some African countries. Surveys of electric vehicle start-ups, drivers, and owner experiences are used to determine the E2&3W's technical feasibility and ability to compete with petrol scooters (p-scooters). SimaPro 9.4 software together with Ecoinvent 3.8 database was used to conduct a cradle-to-the-grave analysis of the environmental impact of using electric scooters (e-scooters). The research found that Africa's E2&3W's have a 0.2% market share compared to gasoline versions. The main disadvantage of e-scooters is their limited range and battery life. The average range and speed are 50 ​km and 50 ​km/h, respectively. Overloading of E2&3W caused damage to traction motors and was of major concern to distributors. The main advantages of E2&3W are their low operating costs and low environmental impact. In South Africa, the total environmental impact of e-scooters outweighed that of p-scooters. Emissions that have a direct impact on human health, were significantly lower for e-scooters than for p-scooters. The lack of battery performance standards, battery swapping station standards, and charging station standards negatively affects the quality of imported e-scooters. African countries need to implement electric vehicle standards, and battery recycling policies, and establish electric vehicle training and research centers.
