The invention provides a battery pack, an electric vehicle and an energy storage device. The battery pack comprises a frame body, a plurality of single batteries and a plurality of first exhaust one-way valves; the frame body is provided with a containing cavity and four side plates; a first exhaust channel is formed in at least one side plate; a plurality of first air inlet holes are formed in the side plates at intervals; the containing cavity is communicated with the first exhaust channel through the first air inlet holes; the plurality of single batteries are arranged in the containing cavity; at least one end surface of each single battery is provided with an explosion-proof valve; the explosion-proof valves are in one-to-one correspondence with the first air inlet holes; the first exhaust one-way valves correspond to the first air inlet holes in a one-to-one mode; the first exhaust one-way valves are arranged on the face, facing the first exhaust channel, of the side plate; and the first exhaust one-way valves cover the first air inlet holes so as to seal first exhaust holes. With the first exhaust one-way valves adopted, the explosion-proof performance and safety of the battery pack are improved.
