Power battery pack it is a common battery assembly form in the fields of electric vehicles, energy storage systems, etc. Its total voltage refers to the voltage value of the whole battery pack in the working state. The total voltage range of the power battery pack depends on the type and connection mode of the selected battery. The total voltage of different power battery packs will directly affect the performance, mileage and safety of the equipment. This article will introduce the range of total voltage of power battery pack, influencing factors and its application in different fields.

1. Total voltage range of power battery pack
   the total voltage range of the power battery pack depends on the voltage and connection mode of the battery cells inside the battery pack. The total voltage range of common power battery pack is as follows:

• lithium Titanate battery pack: the total voltage range is usually 200V-400V, which is mainly used in electric vehicles and other fields.
• Lithium iron phosphate battery pack: the total voltage range is usually 300V-500V, which is used in electric vehicles, energy storage systems and other fields.
• Lithium manganese oxide battery pack: the total voltage range is usually 200V-600V, which is suitable for electric vehicles, industrial robots and other fields.

2. Factors affecting the total voltage of power battery pack
   the determination of the total voltage of the power battery pack is affected by the following factors:

• battery cell voltage: the rated voltage of the battery cell determines the total voltage range of the battery pack.
• Battery connection mode: Series connection and parallel connection will affect the total voltage value of the battery pack.
• Application Requirements: different application scenarios have different requirements for the total voltage of the battery pack, for example, electric vehicles have specific voltage requirements for endurance and performance.

3. Influence of total voltage of power battery pack
