Method and apparatus for controlling liquid-cooled energy storage system, electronic device and storage medium

A method for controlling a liquid-cooled energy storage system comprising a liquid-cooled unit and a water pump, the method comprising:

• cyclically acquiring a water inlet pressure and a water outlet pressure of the liquid-cooled unit;
• obtaining a difference between the water inlet pressure and the water outlet pressure in each cycle according to the acquired water inlet pressure and the acquired water outlet pressure;
• performing calculation according to the difference between the water inlet pressure and the water outlet pressure in a current cycle and the difference between the water inlet pressure and the water outlet pressure in a previous cycle to obtain a pressure difference change value in the current cycle;
• and
• in the current cycle, if the pressure difference change value is less than or equal to a first preset change value, controlling a water pump duty cycle of the water pump according to a system temperature of the liquid-cooled energy storage system and a preset temperature control policy;
• otherwise controlling the water pump duty cycle of the water pump according to a preset liquid leakage detection policy.
