Original Abstract

An electric bike (1kW) with a Li-Ion accumulator 28V/42A was constructed and tested in the Department of power electrical and electronic engineering. Panasonic cells CGR18650C (ca 2Ah) are used in the accumulator. The battery is completed with 7 serial-connected blocks. Each block is a set of 21 parallel-connected cells. The accumulator was tested in the vehicle since 2005 till now. During the tests a distance of approx. 12000km was driven. Some theoretical know-how about the used charging and discharging strategy and about the battery management system is proposed in this contribution. Practical results regarding the lifetime, capacity decreasing, charging problems, temperature dependencies and cell voltage balancing are visible from the long-time experiment described in this contribution too.
