[0002] In the energy storage system, especially the electrochemical energy storage system, temperature control is a key factor to ensure system performance and prolong service life.

[0003] At the same time, the existing water route assembly has the following disadvantages: 1.

The existing water route assembly generally cannot adjust the internal pressure of the fluid according to the change of pressure, so the actual use stability is affected, for example, liquid shrinkage (internal pressure reduction) or liquid expansion (internal pressure increase) caused by temperature drop, which is also a load on the pipeline assembly, affecting the use stability.

[0014] In actual design, the liquid supply port and the liquid return port are also provided with pressure sensors and temperature sensors, so that the temperature or water flow rate can be adjusted according to different preset conditions.

[0015] The water pump and the refrigeration device are preferably variable frequency devices.

[0016] An energy storage system liquid device includes a housing provided with an inner cavity, the above-mentioned water pipeline system assembly provided in the inner cavity, and a fan module.
