Abstract

The depletion of fossil fuel sources and the increasing environmental pollution caused by the burning of motor vehicle fuels are major problems worldwide that need to be solved. One of the promising solutions to overcome energy security and environmental pollution is the use of electric vehicles. E-bikes are one of the most popular electric vehicles because of their many benefits. A valve-regulated lead acid battery (VRLA) is now the most common energy source for electric vehicles. It is heavy and unsafe for the user due to its poor energy density. Lithium ion batteries may be a feasible solution. One type of Li-ion battery that is environmentally friendly is lithium ferro phosphate (LFP). The potential that exists encourages researchers to conduct research and compare the performance of VRLA batteries with LFP batteries. The data retrieval method is carried out using the Arduino data logger application and is equipped with a microcontroller to read current and voltage. The test results prove that the LFP battery has good voltage stability. The distance that can be traveled is quite long, which is up to 50.16 km, because it is supported by a large capacity. On the other hand, VRLA can only travel 37.83 kilometers. Furthermore, the energy density of LFP batteries is great. The VRLA battery has a low energy density of 38.7 Wh/kg, whereas the LFP battery has a higher energy density of 117 Wh/kg, making it lighter and safer for users.
利用磷酸铁锂电池和电池管理系统提高电动自行车性能
化石燃料资源的枯竭和机动车燃料燃烧造成的日益严重的环境污染是世界范围内亟待解决的重大问题。克服能源安全和环境污染的有希望的解决方案之一是使用电动汽车。电动自行车是最受欢迎的电动交通工具之一,因为它有很多优点。阀控铅酸电池(VRLA)是目前电动汽车最常用的能源。它的能量密度很低,对用户来说很重,很不安全。锂离子电池可能是一个可行的解决方案。一种环保的锂离子电池是磷酸铁锂(LFP)。存在的潜力鼓励研究人员进行研究,并将VRLA电池与LFP电池的性能进行比较。数据检索方法使用Arduino数据记录器应用程序进行,并配备单片机读取电流和电压。试验结果表明,LFP电池具有良好的电压稳定性。可行驶的距离相当长,可达50.16公里,因为它有很大的容量支持。另一方面,VRLA只能行驶37.83公里。此外,LFP电池的能量密度很大。VRLA电池的能量密度较低,为38.7 Wh/kg,而LFP电池的能量密度较高,为117 Wh/kg,更轻,对用户更安全。
