1. A maintenance device for coupling to a battery pack of an electric vehicle and performing maintenance on the battery pack, comprising:
a device housing;
an electrical connector configured to connect to a connector of the battery pack;
a controller in the housing configured to control operation of the maintenance device;
measure relative voltages between electrical connections of the connector of the battery pack;
determine a virtual pin mapping of the electrical connections based upon the voltage and further identify electrical connections to a temperature sensor in the virtual pin mapping based upon the measured relative voltages; and
perform maintenance on the battery pack based upon the determined virtual pin mapping.
