1. A method of testing the electrical performance of a battery tub for an electric vehicle while the tub is being assembled, said assembled battery tub including a plurality of batteries, a plurality of temperature sensing devices, and at least one battery monitor module, said batteries presumed to be in a full state of charge prior to being assembled in the tub, said method not including charging a battery if the battery is not in a full state of charge prior to being assembled, said method comprising the steps of:

  • determining an identification of a battery before it is assembled within the battery tub;

    mounting the battery within the tub if the identification corresponds to predetermined criteria;

    measuring the voltage of the battery after it is mounted within the tub, said step of measuring the battery voltage includes determining whether the battery has a measured battery voltage within an acceptable battery voltage range;

    determining whether the battery is electrically connected properly if the measured battery voltage is not within the acceptable battery voltage range;

    removing the battery from the tub if the battery is electrically connected properly and the battery voltage is not within the acceptable battery voltage range;

    mounting a temperature sensor within the tub;

    determining if a temperature measurement of the temperature sensing device is within an expected temperature range;

    determining whether the temperature sensing device is properly connected if the temperature measurement is not within the expected temperature range; and

    separately repeating the foregoing steps for all of the batteries and temperature sensing devices in a predetermined sequence until all of the batteries and temperature sensing devices are assembled within the tub.
