The present disclosure discloses an energy storage device, including a battery pack, a waterproof plug, and a water immersion detection unit. The battery pack includes a housing and a connection terminal. The housing has an opening, and the connection terminal is disposed at the opening. The waterproof plug includes an electrical connection member configured to electrically connect to the connection terminal in response to the waterproof plug covering the opening, and configured to generate a first signal in response to water flowing into the opening. The water immersion detection unit is configured to determine that the water flows into the opening through detecting the first signal. The waterproof plug is small in size and has a simple structure, which is beneficial for reducing production costs of the energy storage device.

Energy storage device

Provided are a control method for a home energy system (), an energy system, an energy management device, and a computer-readable storage medium. The control method includes: when the home energy system () is in a grid-connected state and a non-time-shifting power generation device is in a power-supply state, obtaining net power of the home energy system () during each power consumption time period of a current day, and when the net power is smaller than zero, controlling, based on an electricity price of the public grid (), the home energy system () to be power by an energy storage device () or by the public grid (); and when the net power is greater than zero, controlling the power generation device to output electric energy to the energy storage device () or the public power grid ().
