Embodiment 1
[0110] The plurality of sensors in Embodiment 1 also includes a CO (carbon monoxide) sensor, a VOC (Volatile Organic Compounds, volatile organic compound) sensor and a smoke sensor, and the parameter value measured and output by the CO sensor is a CO concentration value, and the VOC The parameter value measured and output by the sensor is a VOC voltage value, and the parameter value measured and output by the smoke sensor is a smoke voltage value.
[0111] It should be noted that when the safety state of the battery box is in the first-level state, all the sensors except the temperature sensor are in the off state. As the temperature inside the battery in the battery box gradually rises, the heat-generating chemical reaction becomes more and more intense, producing gases such as CO, volatile organic compounds, and smoke. These gases are released from the battery safety valve, so that each sensor can measure these gases , and obtain corresponding measurement values for the sa...

The invention discloses a safety monitoring and early warning method, device, equipment and medium based on battery energy storage. The method includes the steps of: monitoring the ambient temperature in a battery box used for battery energy storage in real time, and determining the safety of the battery box based on the ambient temperature State level; if the ambient temperature is less than the first preset temperature value, then determine that the security state level is a first-level state; if the ambient temperature is equal to or greater than the first preset temperature value and less than the second preset temperature value, then determine the security state level It is a secondary state, and blocks the heat-generating chemical reaction of the problematic battery inside the battery box; if the ambient temperature is equal to or greater than the second preset temperature value, the safe state is determined according to the parameter values measured by multiple sensors installed in the battery box The level is the preset dangerous state level, which realizes the safety state of the battery is divided into multiple levels according to the ambient temperature and other parameter values, and the management personnel can take corresponding measures to eliminate the dangerous state according to the safety state level.
Description
technical field [0001] The invention relates to the field of batteries, in particular to a safety monitoring and early warning method, device, equipment and medium based on battery energy storage. Background technique [0002] In recent years, under the dual pressure of traditional fossil energy shortage and environmental protection issues, my country has actively supported and developed new energy industries, and electrochemical energy storage systems with lithium-ion batteries as the main storage medium have developed rapidly. The electrochemical energy storage system can solve the random and intermittent problems of wind power and photovoltaic power generation, and play the role of peak regulation and frequency modulation, flexible output, and reactive power support, so as to make full use of wind power and photovoltaic energy, improve the quality of power supply and the safety and economy of the power grid sex. However, limited by the product quality, the integrated ins...
