A Wide Range of Products

As of 2009, over 81 million electric bikes on the road in China, the number of which is expected to increase rapidly. Lead acid motive battery is installed in over 90 percent of all electric bikes in China. Chaowei is dedicated to the production of these batteries, as testified by its leading market share and the fact that all motive battery products for electric bikes produced by Chaowei are lead-acid. The Company also produces seven models of lead-acid motive batteries for electric cars and four models of storage batteries, manufacturing and selling wind and solar energy storage batteries and lead-acid batteries for electric cars on a small scale. All of our battery products are produced and sold under the brand and trademark of "CHILWEE".

The key components of a lead-acid motive battery include electrode plates and fiber glass dividing plates. The number and the size of electrode plates required to be installed in a lead-acid motive battery will depend on the required level of its storage capacity and power output. The electrode plates are coated with oxidized lead and alloy lead. Pairs of positively charged electrode plates and negatively charged electrode plates each separated by a fiber glass dividing plate are bound together by metal strips and installed into the plastic casing of a lead-acid motive battery. The battery is then filled with sulphuric acid and charged with electricity.

The Company produces 19 models of lead acid motive batteries for electric bikes and electric vehicles. Major models of related batteries are:
