 GM recommends that a Volt battery fire be fought with water rather than dry chemicals , and rates the Volt battery as having no explosion or electrocution hazard as the result of a collision . The high @-@ voltage system is designed to shut down automatically in the event of an airbag deployment , and to detect a loss of communication from an airbag control module . During the Volt development the lithium @-@ ion battery pack was subjected to a wide range of tests , including overcharge , discharge , vibration , excessive heat and cold , short circuit , humidity , fire , crush , water immersion , salt water immersion , and nail penetration .
