1. An energy storage device, comprising:
a battery pack comprising a housing and a connection terminal, the housing having an opening, and the connection terminal being disposed at the opening;
a waterproof plug comprising an electrical connection member, the electrical connection member being configured to: electrically connect to the connection terminal in response to the waterproof plug covering the opening, and generate a first signal in response to water flowing into the opening; and
a water immersion detection unit configured to determine, by detecting the first signal, that the water flows into the opening, wherein:
the connection terminal comprises a first needle seat and a second needle seat;
the water immersion detection unit is connected to the first needle seat and the second needle seat;
the electrical connection member comprises a first signal needle, a second signal needle, and a water immersion detection wire;
the first signal needle is connected to the second signal needle through the water immersion detection wire;
the water immersion detection wire is configured to generate the first signal in response to detecting water immersion;
in response to the waterproof plug covering the opening, the first signal needle is electrically connected to the first needle seat, and the second signal needle is electrically connected to the second needle seat; and
the water immersion detection unit is configured to detect, by means of the first needle seat and the second needle seat, an electrical parameter of the water immersion detection wire to detect the first signal.
