摘要
特斯拉电动车的核心是其先进的锂电池成组技术及其电池管理系统,由此实现了续航里程和安全性的飞跃。特斯拉采用工业化程度高、相对成熟的电池组单元。其技术优势在于:稳定可靠、动力性能卓越,续航里程最高可达480 km。这有助于解决续航焦虑问题,也对快速充电技术提出了更高的要求。而特斯拉Model S电动汽车最大的电池容量为85 k Wh,由7 000多颗18 650电池提供电量支持。如此大的电池容量,必须有更快的充电速度与之相匹配。对特斯拉的电池管理系统和快速充电技术进行简要的分析,并展望未来电动汽车技术的前景。
Based on the present lithium ion battery,Tesla electric vehicles have made a great progress in driving miles and safety by developing its unique Battery Management System（ BMS）. The battery system of Tesla has been well developed with stable electrochemical performances and manufactured in a great number. Because of superior performance of its battery system which is composed of more than 7 000 cells and own total capacity as high as 85 k Wh,a Tesla car can drive up to 480 km over one full charge. Therefore,a large current rate is necessary to charge such a big battery pack in an acceptable time. This paper figures out several significant points on Tesla＇s BMS and fast charging technology. A sound analysis of the current technology brings insights into the future prospective. Particularly fast charging through wireless technology is deemed to play a key role in the future.
