Systems and methods may coordinate and provide bidirectional energy transfer events between electrified vehicles and other devices or structures, such as for supporting transient loads associated with the devices/structures. Battery life information and driving habit information may be leveraged for selecting an appropriate energy transfer strategy for any given vehicle, traction battery pack, structure, and/or grid power source condition. The proposed systems/methods may thereby align grid demand charge strategies to each vehicle's battery life, thereby preserving the life/warranty and asset utilization of the traction battery pack over the entire usage life of the vehicle.
