[0002] In recent years, photovoltaic battery packs have been increasingly widely used in civil and industrial production. To ensure the continuous and stable operation of the system, it is very necessary to research and design an energy consumption detection system for photovoltaic battery packs that is efficient, low-cost, accurate, convenient, fast, and practical. The single voltage of a photovoltaic battery pack is relatively low and it is rarely directly used in its natural form. Most of them are connected in series or in a series-parallel combination. At the same time, the power of the photovoltaic battery pack will gradually decline with the extension of the working time and the increase of the power consumption time. It is very difficult to ensure that the working characteristics of each single photovoltaic battery pack in the combination are the same. Therefore, reasonable monitoring equipment must be used to find out the lines with higher energy consumption by online real-time detecting parameters such as the charge and discharge voltages, temperatures of each single photovoltaic battery pack, and the charge and discharge current and charge and discharge voltage of the entire photovoltaic battery pack, and analyze the reasons for the high energy consumption to improve the efficiency of photovoltaic power generation.
