Abstract

The invention provides a method and a system for detecting a lithium battery matched with fuel power generation. The method comprises the steps: receiving a query instruction of a user, and transmitting the query instruction to battery management equipment; receiving query data returned by the battery management equipment, wherein the query data is queried by the battery management equipment according to the query instruction, and comprises one or a combination of the following data: SOC, total voltage, lowest monomer voltage, highest monomer voltage, highest monomer temperature and lowest monomer temperature; and analyzing the query data to obtain the safety state of a lithium battery. According to the method, various data, including SOC, total voltage, lowest monomer voltage, highest monomer voltage, highest monomer temperature and lowest monomer temperature, of the lithium battery can be monitored, the safety state of the lithium battery is analyzed according to the monitored data,and the use condition of the lithium battery can be comprehensively monitored.

Description

technical field [0001] The invention belongs to the technical field of fuel cells, and in particular relates to a detection method and system for lithium batteries used in fuel power generation. Background technique [0002] Fuel cell (PEMFC) technology is the most efficient means of utilizing hydrogen energy. A fuel cell is a device that directly converts the chemical energy of hydrogen into electrical energy. It has the advantages of high efficiency, low noise, and zero pollution, and is playing an increasingly important role in today's society. Fuel cells usually need to assemble multiple single cells in series to form a stack. [0003] A large amount of energy will be generated during the fuel cell test, and lithium batteries will be used to store the energy generated in the actual test, which will bring better social and economic benefits. At the same time, it is necessary to detect the usage of the lithium battery during the use of the lithium battery. However, the ...
