Abstract: A battery pack including fire extinguishing equipment. The fire extinguishing equipment includes a first chamber, a second chamber, and an activation line. The first chamber stores a fire extinguishing chemical agent, the second chamber stores a gas-generating chemical agent, and the activation line extends into the second chamber to be in contact with the gas-generating chemical agent. The second chamber includes a pressure relief opening, and the pressure relief opening is in communication with the first chamber, and is configured to spray the gas in the second chamber to the first chamber. The first chamber includes a discharge opening, and the discharge opening is configured to discharge the fire extinguishing chemical agent in the first chamber after the gas generated after the gas-generating chemical agent is ignited enters the first chamber.
