【 摘 要 】

The paper presents the problem of mechanical energy recovery during the decelerating motion of a vehicle and its conversion into electric energy stored in vehicle batteries. It is known that each energy conversion is accompanied by some losses that cause a reduction in the efficiency of the transformation. The aim of the study is the analytical determination of efficiency occurring in the energy conversion system. The methodology developed by the authors will allow for an analytical estimation of the energy amount that will be accumulated in the battery of an electric or hybrid vehicle as a result of recovering part of the braking energy. Simulation tests were conducted under the assumption of specific, different traffic conditions.
