Get a quoteIn addition, a PSO type technique is introduced to optimize the battery design. Neither study considers activation and concentration overpotentials. One factor that critically affects battery efficiency is the flow rate. The flow rate is related to the charge or discharge current of the battery and the electrolyte flow rate.
Linking with Eq. 22, the higher the current, the greater the flow rate needed; therefore, the pressure losses will increase, implying a higher need for pump power. This probably directly limits the value of the flow factor. Knowing the optimum flow factor for battery operation is of great interest to optimize battery efficiency.
The flow rate of the battery directly affects the pressure losses that occur and, by extension, the power that the pumps must provide for the battery to operate. However, as studies such as Ref. 20 have reported, flow rate also influences battery voltage and shunt currents, thus affecting the battery power.
Temperature is one of the most significant factors affecting battery performance. Extreme temperatures, whether hot or cold, can reduce a battery’s capacity and lifespan. High temperatures can cause batteries to degrade more quickly, while low temperatures can reduce a battery’s ability to provide energy.
The results show that the lower the current imposed for charging and discharging, the more flexibility there is for choosing a flow factor that maximizes system efficiency. The variation of currents has a direct influence on the pressure losses.
