Abstract
Keywords: Rechargeable battery, hybrid car, power management, battery electric parameters, management algorithms.
Hybrid cars use specific batteries, unlike electric cars. Operating modes are also different. A first set of secure operating rules is imposed by the battery manufacturer. Manufacturers also recommend measures for efficiency and reliability improvement. Design and practical construction of the vehicle generate other restrictions. An appropriate management of the hybrid car battery will avoid electrical incidents, will extend the battery lifetime and will increase performance. Based on the practical experience, included the one achieved by the activities deployed in the no.166/2007 research contract, management algorithms and considerations are presented. The algorithms are and will be implemented in electronic circuits special designed for interfacing the traction control system and diagnose and operation data loggers.
