Problems solved by technology

When working for a long time, the temperature difference between different batteries is too large, which leads to obvious differences in the health status of high-temperature batteries and low-temperature batteries. As a result, the capacity of the high-temperature battery cell decreases, which reduces the overall capacity of the energy storage module, resulting in a decrease in the overall revenue of the system

Abstract

The invention provides an energy storage module, an energy storage device and a power generation system. The energy storage module comprises a first battery cell, a second battery cell and an air duct structural part, an air duct is arranged in the air duct structural part, the air duct structural part comprises an air inlet end and an air outlet end which are located at the two ends of the air duct, and the first battery cell and the second battery cell are arranged outside the air duct structural part and sequentially arranged between the air inlet end and the air outlet end. The air duct structural part comprises a first air duct area and a second air duct area, the first air duct area corresponds to the first battery cell, the second air duct area corresponds to the second battery cell, and the heat dissipation area in unit volume of the second air duct area is larger than that in unit volume of the first air duct area, so that the temperature difference between the second battery cell and the first battery cell is reduced. The heat dissipation area in the unit volume of the second air duct area is set to be larger than the heat dissipation area in the unit volume of the first air duct region, so that the problem that the temperature difference between the second battery cell and the first battery cell is too large can be solved.

Description

technical field [0001] The present application relates to the technical field of energy storage, in particular to an energy storage module, an energy storage device and a power generation system. Background technique [0002] In order to overcome the severe intermittency problems of large-scale photovoltaic power generation or wind power generation, and with the rapid decline in the cost of energy storage devices, battery energy storage devices, due to their application flexibility, high reliability and controllability, high energy density, etc. Both the power generation side and the power consumption side have developed rapidly, and the installed capacity has also increased significantly. [0003] The energy storage module includes a plurality of battery cells, and the temperature of the battery cells at different positions is different during the heat dissipation process of the energy storage module. When working for a long time, the temperature difference between differe...
