The role of liquid cooling energy storage in Turkmenistan

The simulation results show that the liquid cooling system can significantly reduce the peak temperature and temperature inconsistency in the ESS; the ambient temperature and coolant flow rate of the liquid cooling system are found to have important influence on the ESS thermal behavior.

It was presented and analyzed an energy storage prototype for echelon utilization of two types (LFP and NCM) of retired EV LIBs with liquid cooling BTMS. To test the performance of the BTMS, the temperature variation and temperature difference of the LIBs during charging and discharging processes were experimentally monitored.

In the actual operation, the ambient temperature in LIB ESS may affect the heat dissipation of the LIB modules. Consequently, it is necessary to study the effect of ambient temperature on the cooling performance of the liquid-cooling system.

With the liquid-cooling system on, from the initial temperature, the maximum temperature rise of the LIBs is 2 K at the end of the charging process and 2.2 K at the end of the discharging process compared with the initial temperature.

Under the conditions set for this simulation, it can be seen that the liquid-cooling system can reduce the temperature rise of the battery modules by 1.6 K and 0.8 K at the end of charging and discharging processes, respectively. Fig. 15.

The simulation predictions indicate that the liquid cooling BTMS is well designed and can significantly reduce the peak temperature and temperature inconsistency in the ESS under various operating conditions.
