Methods and systems are described that maintain and service electric vehicle battery packs and assemblies. The methods and systems automatically remove a used battery pack from an electric vehicle, replace the used battery pack with a charged battery pack, and service the removed used battery pack for subsequent vehicle installation. The servicing of the used battery pack includes removing a desiccant cartridge from the used battery pack and renewing a desiccant material associated with the desiccant cartridge. This desiccant material may be renewed by drying the desiccant cartridge using a heater. The used battery pack may be conveyed to a battery charger to charge the used battery pack to a predetermined charge level. The renewed, dry, desiccant cartridge may be attached to any battery pack and installed in an electric vehicle after the battery pack has been charged.
