Battery voltage refers to the electrical potential difference between the positive and negative terminals of a battery. It is crucial because: Power Output: Determines how much power a battery can deliver to devices. State of Charge (SoC): Indicates the remaining energy in a battery, helping users understand when to recharge.
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.
High-voltage cycling is a direct driver of intercrystalline cracking, and higher voltages lead to the formation of many irreversible dislocations and cracks, which is detrimental to the performance of the battery.
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.
Battery energy storage moving to higher DC voltagesFor improved efficiency and avoided costsThe evolution of battery nergy storage systems (BESS) is now pushing higher DC voltages in utility scale applications. The Wood Mackenzie Power & Renewables Report is forecasting phenomenal growth
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.
