| Summary: | Title screen Sources of irregular electricity generation (wind generators and solar power plants) cannot guarantee a stable supply of electricity to consumers. The only solution to the problem of involving such non-traditional renewable energy sources in the actual power supply is the accumulation of electricity in energy storage systems (ESS). The battery ESSs are considered promising according to several criteria. The objective lack of statistics on failures of battery energy storage systems and universal mathematical models for predicting the thermal runaway of electrochemical batteries is a limiting factor in the development of such technology for storing large volumes of electricity. This study analyzes the thermal conditions of a large lead-acid energy storage system are analyzed taking into account two mechanisms of heat generation for typical operating modes of battery and varying the heat exchange characteristics of the battery system with the external environment: ambient temperature and heat exchange intensity. The task of numerical temperature analysis is solved within the framework of a mathematical model with lumped parameters in the form of a system of ordinary differential equations. Numerical analysis made it possible to identify operating modes with a high probability of thermal runaway. It can occur even under conditions of heat exchange between the battery system and the external environment in the typical range of changes in ambient temperatures and heat transfer coefficients. For example, reducing the heat transfer coefficient of the housing surface of the basic cells of the battery assembly to 5 W/(m2 ·K) leads to thermal runaway of the lead-acid batteries already at an ambient temperature Tsurround=28 °C and other normal parameters Текстовый файл AM_Agreement |
