Abstract

The invention discloses a thin film pressure nose array-based energy storage battery. The thin film pressure nose array-based energy storage battery comprises a battery module, a battery management system, a battery safety valve and a thin film pressure sensor, wherein the battery safety valve is used for releasing pressure in a single battery, the thin film pressure sensor is used for sending a monitoring signal to the battery management system, and the battery management system is used for monitoring and analyzing a running state of the battery module. In the energy storage battery providedby the invention, the thin film pressure sensor is arranged on a surface of the battery module and is used for monitoring a state of the safety valve and transmitting the monitoring signal to the battery management system, real-time monitoring and advanced early-warning can be performed on thermal runway of the energy storage battery in the energy storage power station, so that the safety runninglevel of the energy storage power station is improved. The invention also discloses a state judgment method of the thin film pressure node array-based energy storage battery.

Description

technical field [0001] The invention belongs to energy storage technology, and in particular relates to an energy storage battery based on a thin-film pressure node array and a state discrimination method thereof. Background technique [0002] Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. Energy storage technology is a key technology to solve the problems of large-scale access to renewable energy and curtailment of wind and light. It is an essential technology for the development of distributed energy, smart grids, and energy Internet. At the same time, energy storage technology is also an important supporting technology to solve the peak-shaving and valley-filling of conventional power, and improve the efficiency, safety and economy of conventional energy generation and transmission. [0003] Energy storage technology can increase the ratio of clean energy power generation, realize the clean and efficient us...
