1. A portable exchange robot for exchanging a battery module in a vehicle, said robot comprising:

  • a microprocessor;

    a battery tray configured to hold a modular battery unit;

    a lift in mechanical communication with said battery tray, said lift to raise and lower said battery tray;

    a motor in mechanical communication with said lift and in electrical communication with said microprocessor, said motor to raise and lower said lift;

    a plurality of wheels that propel said portable exchange robot;

    a navigation system in electrical communication with said microprocessor and at least one of said plurality of wheels to drive the dispensary robot between a modular battery dispensary and a vehicle;

    a memory in electrical communication with said microprocessor, said memory storing instructions for;

    positioning said robot under said modular battery in said vehicle;

    unloading a depleted battery module from said modular battery in said vehicle, wherein said instructions for unloading said depleted battery further comprise;

    raising said battery tray to engage said depleted battery module;

    monitoring a weight on said battery tray during said raising, said weight sensed by a weight sensor on or proximal to said battery tray;

    stopping said raising when said monitored weight reaches a threshold value; and

    after said stopping, sending a message to said vehicle that said battery tray has engaged said depleted battery module; and

    returning said depleted battery module to said modular battery dispensary; and

    a wireless communication system operable to be in electrical communication with said modular battery dispensary and said vehicle.
