Abstract

International audience; This paper addresses the challenge of monitoring battery in fleets of electric vehicles (EV). The goal is to identify the different EV utilization modes, during real use, and to highlight the constraining conditions to manage battery health evolution. The other [...]

Abstract

The overall performance of battery packs may be affected by imbalances between the series connected cells which is more likely in packs with high number of cells needed to provide a high voltage as needed for example in electric vehicles. In this case, the overall capacity and power [...]

Abstract

Electric vehicle (EV) chargers can be controlled to support the grid frequency by implementing a standard-compliant fast primary frequency control (PFC). This study addresses potential effects on power systems due to control discreteness in aggregated EVs when providing frequency [...]

Abstract

International audience; This paper presents a study which follows the present trend in the field of electric (or hybrid) vehicles E(H)V, having in mind that the major drawback of these last ones is the autonomy problem. Thus, by using a hybrid energy source (formed by ultracapacitors [...]
