As a result, battery energy storage systems (BESSs) are becoming a primary energy storage system. The high-performance demand on these BESS can have severe negative effects on their internal operations such as heating and catching on fire when operating in overcharge or undercharge states.
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.
During the charging process, when the liquid-cooling system is off, the LIB temperature increases as the charging proceeds. After the liquid-cooling system is on, when the ambient temperature is 303 K, the battery temperature first decreases gradually, then rises slowly.
However, the active cooling strategy of liquid cooling only by battery thermal management not only consumes a large amount of water pump power but also is difficult to guarantee the battery temperature difference in large battery pack systems.
As electric vehicles (EVs) are gradually becoming the mainstream in the transportation sector, the number of lithium-ion batteries (LIBs) retired from EVs grows continuously. Repurposing retired EV LIBs into energy storage systems (ESS) for electricity grid is an effective way to utilize them.
The three cases of distributed generation and battery storage are considered simultaneously. The proposed method is applied to the test grid operator IEEE with 37 buses, and reductions in annual energy losses and energy exchange are obtained in the ranges 34–86% and 41–99%, respectively. ...
