Currently Charge is nothing more than a placeholder. To really use it we need to

• define parameters for Charge functionality (target charge level?, predefined duration?)
• add battery properties (capacity, charging rate etc.) to AmrDescription
• add real time consumption calculation to AmrMobilityHelper and replace hardcoded placeholder
• implement battery surveillance in AmrLogicalAgent
• add states to OrderStates to handle charging
• include charging into fsm

Sidenote: VDA 5050 allows AGVs to suspend a task for charging and then resuming it.
