The first effect is dominating, which means that battery mass decreases with system voltage. As a second effect, increasing voltage requires more serially connected cells that increase the number of voltage-sensing channels and therefore the cost of the battery management system is also increased.
The system-level voltage has an impact on the battery cell connections. For higher voltage, more cells are connected in series and fewer in parallel for the same storage capacity, however, the pack losses stay the same. Lower currents allow busbar connections with smaller cross sections, which helps to reduce the mass.
Battery voltage is the function of SOC, cell temperature and demanded current due to the voltage drop in internal equivalent resistance. It was found that the colder weather is, the smaller battery voltage is, and more stress on the battery comes from the earlier operation of the FW strategy.
It implies that any battery voltage variation impacts on the IM performance as well as the FW operation. The variation in battery voltage is caused by several reasons. However, the low-temperature effect is being paid more attention on, especially in Canada, for instance.
These determining factors include temperature, State of Charge (SOC), rest time, power rate, depth of discharge, and heat , , . Each of these factors contributes to the overall performance and its degradation process, whether the battery is operational or static.
The results show that the battery suffers from a voltage reduction by larger internal resistance as the temperature decreases. Moreover, the higher current is required for activating the FW process. However, the inner resistance growth produces more heat inside the cell that affects the battery electrical parameters as well as the system.
