Adaptive battery management systems for the new generation of electrical vehicles

Proper functioning of rechargeable batteries is of crucial importance for any electrical vehicle, especially for Plugin Electrical Vehicles (PEV). Modern Battery Management Systems (BMS) provide a driver for a number of important indications, such as remaining operation time, remaining charge and power. Therefore, BMS is a key element of PEV. However, the performance of the batteries deteriorates during the cycle life, in particular the capacity fades and impedance grows, leading to a decrease in battery power. BMS may decrease these negative effects without creating inconvenience for the end-user. A number of advanced battery charging algorithms were developed in the recent decade. These algorithms can significantly improve the performance of PEV facilitating their mass production. © 2009 IEEE.
