基于单片机系统的电动自行车专用电池容量测试仪的设计（Design of battery capacity tester based on single chip microcomputer system） (4) 22 December 2010 journal of henan institute of engineering (natural science edition) JOURNALOFHENANINSTITUTEOFENGINEERINGVo1.22, No. 4 Dec. 2010, based on single chip microcomputer system is the design of the electric bicycle battery capacity tester wei-dong xing (zhengzhou city sewage purification co., LTD., zhengzhou, henan 450000) abstract: this paper introduces a kind of electric bicycle battery capacity tester based on single chip microcomputer system, and its working principle, hardware circuit, software design, etc In this paper, we have found a simple and reliable battery matching scheme which is simple and easy to use. generation In order to solve the problem of the bottleneck in production and maintenance, the problem of the bottleneck in production and maintenance has been greatly improved. Key words: battery; 89C51 single chip microcomputer; Constant current; Electron negative planting Chinese library classification number: TM933 literature identifier: A article number: 1674-330 (2010) x 04-330-03 some brand electric vehicles use battery in the months after customers to use (generally within six months, not 3 m), found that the individual cells In the case of premature aging, the factory needs to replace the whole battery for the customers, and the maintenance costs are relatively large. The replacement of the battery pack is analyzed and analyzed Now, 3 of the battery pack in the battery failure, not all are almost only a battery failure caused by the cell does not continue to use the entire group, the rest of the two pieces of the battery is almost in the new state. In order to save the maintenance cost, completely can replace damaged battery, battery packs with a piece of the same capacity of the battery for users to continue to use. To measure the battery capacity of the original The method is to use the battery to connect the high power resisto
