A system and method for management of an energy storage system for a vehicle is disclosed. The energy storage system may comprise a battery system for a vehicle such as an electric vehicle or hybrid-electric vehicle. Vehicles may be in a group of fleet. The management system may be configured to use data and information available from data sources over a network or by instrumentation/sensors for vehicle systems. Data and information could be used in a system to manage the configuration and operation of the energy storage system and components, manage/control inventory and use/life-cycle of components, and/or aggregated/analyzed in analytics function for systems and components. Predictive control of the battery system may be implemented through a management system using data sources external to the vehicle. Inventive concepts and features of the systems and methods are indicated in the specification and FIGURES.
