Nominal Voltage refers to the typical output voltage value of a battery under normal operating conditions, which is usually used to indicate the voltage level of the battery type and is not the instantaneous or peak voltage. It is a common parameter in the battery specification sheet, used for system design, battery selection, and performance comparison.
The function and significance include: system matching to help with voltage matching between battery system, motor, and electrical control components; capacity calculation, which can be used for quick estimation of the total energy of the battery pack (Wh = Ah × rated voltage); communication identification, where BMS and external systems identify cell types through nominal voltage; and safety identification, which distinguishes different working voltage ranges,It is conducive to preventing misoperations.
