Immersed liquid-state temperature-adjusting solid-state battery energy storage system

Abstract

The invention discloses an immersed liquid-state temperature-adjusting solid-state battery energy storage system, and belongs to the technical field of energy storage batteries. Each battery module box body is connected with one DC-DC module, all the DC-DC modules are connected in parallel and then connected with a solid-state battery management module, the solid-state battery management module is connected with a DC-AC module, and the DC-AC module is connected to an external power grid. The battery module box body is filled with temperature adjusting insulating liquid, the solid-state battery module is immersed in the temperature adjusting insulating liquid, the solid-state battery module comprises a plurality of solid-state battery single bodies, a plurality of temperature sensors are arranged in the battery module box body, and temperature sensors are connected with the solid-state battery management module. The temperature-regulating insulating liquid in all the battery module box bodies in the system circulates through a temperature-regulating insulating liquid circulating system. The temperature consistency and stability of the solid-state battery can be greatly improved, and the problems that the normal-temperature charging and discharging performance of the solid-state battery is poor, and a traditional temperature control device is poor in uniformity and low in efficiency are solved.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and in particular relates to a submerged liquid-state temperature-regulating solid-state battery energy storage system. Background technique [0002] With the large-scale application of batteries, the safety of batteries has attracted more and more attention. Liquid batteries contain a large amount of liquid electrolyte, which can easily cause the battery to burn or even explode. Solid-state batteries are considered to be the next generation of large-scale development batteries to replace liquid batteries. Solid-state batteries are extremely safe because they do not contain liquid electrolytes. In addition, solid-state batteries also have the advantages of high energy density and high cycle life. However, due to the low ionic conductivity of the solid-state electrolyte and the large internal impedance of the battery, the discharge performance of the battery at room temperature i...
