一、市场前景随着社会的进步,时代的发展,自行车和摩托车有被方便快捷、安全舒适、经济环保的电动自行车取代之势。2003年10月,新的《道路交通安全法》颁布实施,正式将电动自行车纳入非机动车管理范畴,各地电动车数量与日俱增。作为电动车“心脏”的铅酸蓄电池设计使用寿命四年,但一般一年就濒临报废,必须更换。以上海为例,上海现在的电动车保有量超过80万辆,每年需要进入更换的电池高达80万组,数量十分惊人。
First, the market prospects With the progress of society, the development of the times, bicycles and motorcycles have been replaced by electric bicycles that are convenient, safe, comfortable and economical and environmentally friendly. In October 2003, the new “Road Traffic Safety Law” was promulgated and officially incorporated electric bicycles into the management of non-motorized vehicles. The number of electric vehicles in various places is increasing day by day. The lead-acid battery used as the “heart” of electric vehicles is designed to have a service life of four years, but it is generally on the brink of retirement and must be replaced. Taking Shanghai as an example, Shanghai now has more than 800,000 electric vehicles, and it requires as many as 800,000 batteries to be replaced every year. The number is astonishing.
