A Battery Charging Smart System using a Power Management Algorithm and Adaptive Impedance

摘要

The paper proposes an original method experimented by the authors, in order to optimize the charging process for rechargeable batteries. The method involves: testing, adapting and implementing the on board charging function, depending on each type of battery used. First of all, the method proposes an algorithm for the identification of the battery internal resistance, which depends on the wear and tear of the battery. Also, the battery charging dynamics will be created according to its wear status. This is of particular importance in the maximum power transfer especially for batteries with high specific power. Secondly, each battery must be charged taking into account the type of chemical reaction used by the manufacturer in the battery construction process. For this, we will test the dynamics of the discharging in a short time interval and adapt the load to each type of battery differently. The entire process will be implemented and controlled by a microcontroller. The proposed solution is not a new approach, the subject being of great interest especially in the automotive industry, but two of distinct solutions will be implemented cumulatively during the same optimization process.
