The invention discloses a dynamic response large-scale solid-state battery energy storage system, and belongs to the technical field of energy storage batteries. Each normal-temperature solid-state battery module and each high-temperature solid-state battery module are separately connected with a DC-DC module, all the DC-DC modules are connected in parallel and then connected with a solid-state battery energy storage management module, the solid-state battery energy storage management module is connected with a DC-AC module, and the DC-AC module is connected to an external power grid. Each normal-temperature solid-state battery module comprises a plurality of solid-state battery single bodies arranged in an energy storage container. Each high-temperature solid-state battery module comprises a plurality of solid-state battery single bodies and a plurality of heating units which are arranged in the energy storage container. A plurality of temperature sensors are arranged in each of the normal-temperature solid-state battery modules and the high-temperature solid-state battery modules. Temperature sensors and heating units are connected with the solid-state battery energy storage management module. The response speed and the application range of the solid-state battery energy storage system are greatly improved, and the problem of low discharge rate of the solid-state battery at normal temperature is solved.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and in particular relates to a large-scale solid-state battery energy storage system with dynamic response. Background technique [0002] With the vigorous development of new energy sources, the cleanliness of electric power will inevitably accelerate, and renewable energy such as wind power and photovoltaic power generation will usher in accelerated development. As a key supporting technology for a high proportion of renewable energy, battery energy storage technology is indispensable in promoting the low-carbon transformation of electricity. [0003] With the large-scale application of batteries, liquid lithium-ion batteries are likely to cause safety concerns due to the large amount of liquid electrolyte, and the energy density of 300Wh / kg has reached the limit. The solid-state battery does not contain any flammable organic electrolyte, which can fundamentally solve the negat...
