The invention provides a matrix management type solid temperature partitioned energy storage method and device. The matrix management type solid temperature partitioned energy storage method comprisesan energy storage mode and a power supply mode, wherein under the energy storage mode, a low-temperature working medium is subjected to equal-pressure heat absorption through a first module group ofa solid heat storage matrix, then, is insulated and compressed by a compressor, is subjected to an equal-pressure heat release process through a second module group, enters a turbine to be subjected to thermal insulation and expand to work externally, and returns to the first module group for being recycled; and under the power supply mode, the difference is that the working medium is subjected toequal-pressure heat absorption through the second module group, and is subjected to equal-pressure heat release through the first module group. The matrix management type solid temperature partitioned energy storage method and device solve the wind and light abandoning problem in photovoltaic power generation and wind power generation as well as the peak load shaving problem of peak-valley electricity, simultaneously conduct heating during energy storage and power supply, recycle waste heat of waste gas in another heat storage system, and improve heat-work conversion efficiency.
