Can liquid cooling system reduce peak temperature and temperature inconsistency?

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.

Does liquid cooling BTMS improve echelon utilization of retired EV libs?

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.

Does liquid-cooling reduce the temperature rise of battery modules?

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.

Can retired EV libs be used as energy storage systems?

Repurposing retired EV LIBs into energy storage systems (ESS) for electricity grid is an effective way to utilize them. However, the potential safety hazard of retired EV LIBs in echelon utilization poses to become a major concern nowadays.

Does ambient temperature affect the heat dissipation of lib modules?

The cooling plates only contact with the bottom of the NCM battery modules and the left and right sides of the LFP battery modules, the other surfaces of the battery module, for heat dissipation, rely on convection heat exchange with air. In the actual operation, the ambient temperature in LIB ESS may affect the heat dissipation of the LIB modules.

Can retired EV libs be used as a thermal-fluidic model?

The established energy storage prototype accomplishes the echelon utilization of retired EV LIBs, which, combined with the developed full-scale thermal-fluidic model, may be used as a research platform for future study on the thermal safety of ESSs consisting of EV retired LIBs.
