Battery charging and State-Of-Charge management is one of the main relevant issues for developing mobile autonomous robots. This paper presents a complete development of an battery charger for an autonomous mobile robot and a discussion of SOC estimation models. Initially a charger prototype, based on a HalfBridge DC-DC converter, was developed and tested. Furthermore, the MATLAB SimPowerSystem...

Ž . The environmental impact of both the vanadium redox battery vanadium battery and the lead-acid battery for use in stationary applications has been evaluated using a life cycle assessment approach. In this study, the calculated environmental impact was lower for the vanadium battery than for the lead-acid one. The net energy storage efficiency of the vanadium battery was greater due to lower...
