Encapsulated flexibly packaged capacitor module and system

Disclosed are an encapsulated flexibly packaged capacitor module (5) and system. The capacitor module comprises a flexibly packaged capacitor cell (1) and securing plates (3), the securing plates (3) comprising a first securing plate (31) and a second securing plate (32) mounted opposite each other and connected in a snap-fit manner, and further comprises support bodies (4), wherein the support bodies (4) comprise a first support body (41) and a second support body (42) mounted opposite each other and respectively used for connecting a cell positive electrode tab (111) and a cell negative electrode tab (112), and a closed structure for wrapping the flexibly packaged capacitor cell (1) is formed by the two support bodies (41, 42) and the two securing plates (31, 32). The advantage of the above-mentioned solution is assembling a flexibly packaged capacitor cell and a silica gel insulator within the snap-fitted securing plates, namely, additionally providing an "encapsulated" structure for the flexibly packaged capacitor cell and combining and assembling the encapsulated flexibly packaged capacitor module as a whole; and connecting multiple encapsulated flexibly packaged capacitor modules in series or in parallel to form a desired encapsulated flexibly packaged capacitor system, this allowing a good extensibility and easy assembly.
