1. An electrical charging station for charging an autonomous robot having a battery, comprising:

  • a first charging member on the electrical charging station configured to receive a second charging member on the autonomous robot when the autonomous robot is docked with the charging station for charging;

    a communications device configured to receive from the autonomous robot an identifier indicative of a type of battery on the autonomous robot;

    a power supply, electrically connected to the first charging member, configured to charge the autonomous robot according to a charging profile;

    wherein the charging profile is selected based at least in part on the identifier received from the autonomous robot;

    a processor configured to control the power supply to charge the autonomous robot according to the charging profile and to provide the autonomous robot with a state of charge (SOC) periodically during charging;

    wherein the processor is configured to terminate charging when an upper battery voltage threshold has been reached or when a predetermined current level is being output by the power supply, in both cases indicating a fully charged battery, and wherein a last SOC provided to the robot by the processor before terminating charging is used by the autonomous robot as the SOC when the autonomous undocks the charging station.
