摘要
电动自行车正处在高速发展期,它不仅可作为代步交通工具,同时还可作为休闲、健身之器具。电动自行车的发展得益于三大技术的突破,包括动力电池、无刷电机和智能控制系统。而动力电池的选择则要着眼于安全、可靠、比能量大、比功率高、寿命长等。当前,动力电池主要采用阀控铅酸电池、MH/Ni电池、锂离子电池。通过比较、分析,锂离子动力电池的发展前景更为诱人。
Electric bicycles are in rapid development period. It can be used not only as the transportation instruments instead of walk but also the apparatus of the entertainment and body - building. The development benefits from the break - through of three major technologies: motive battery, no - brush motor and the intelligent control system. The choice of the motive batteries should focus on security, dependability, high specific energy, high power density and good cycle life. At present, the motive batteries include valve -regulated lead - acid batteries, Ni-MH batteries, Li - ion batteries. Compared with other batteries, Li - ion batteries have better future.
