Battery pack with dynamic cell spacing

An apparatus comprising:

• a battery pack comprising a front panel;
• a plurality of battery cells located within the battery pack;
• a spacer mechanism configured to operate in a closed configuration and an open configuration;
• a temperature sensor configured to measure a temperature of at least one of the plurality of battery cells;
• and
• a controller configured to:
• monitor the temperature of at least one of the plurality of battery cells using the temperature sensor;
• subsequent to a first temperature value exceeding a first threshold, open the front panel of the battery pack, and
• subsequent to a second temperature value exceeding a second threshold, change the spacer mechanism from the closed configuration to the open configuration,
• wherein the spacer mechanism controls distances between each of the plurality of battery cells, including setting a first distance between each of the plurality of battery cells in the closed configuration, and setting a second distance between each of the plurality of battery cells in the open configuration, wherein the first distance is less than the second distance.
