1. A temperature controlled enclosure comprising:
an internal cavity;
a temperature sensor configured to sense a temperature within the internal cavity;
a temperature control device configured to modify an ambient temperature within the internal cavity; and
an electronic controller configured to:
determine the ambient temperature within the internal cavity,
control the temperature control device to modify the ambient temperature within the internal cavity,
compare the temperature within the internal cavity to a temperature threshold value, and
allow, based on the comparison of the temperature within the internal cavity to the temperature threshold value, charging of a battery pack coupled to a port within the internal cavity.
