Abstract

The invention belongs to the technical field of batteries, and particularly relates to a pressure-controllable soft package battery module, which is characterized by comprising a rectangular module structure frame (1), wherein a structural frame opening (1-3) is formed in the right side of the module structure frame (1), a first partition plate, a single battery fixing frame and a second partitionplate can transversely slide into the module structure frame through the structure frame opening in sequence, a single battery can be installed in the single battery fixing frame, a pressure sensor is arranged between the first partition plate and the single battery, a fixing plate can seal the structure frame opening, one end of a pressure regulator is connected with the fixing plate, the otherend of the pressure regulator is connected with the second partition plate, a controller can be connected with the pressure sensor and the pressure regulator, and the four corners of the inner side ofthe fixing plate are each provided with one pressure regulator. According to the invention, monitoring pressure is provided, the position of the battery is adjusted so that the battery can be kept orkept at the required pressure level, and the battery module and the control system are simple and reliable in structure and high in safety.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a pressure-controllable soft pack battery module. Background technique [0002] A modular battery is a battery pack in which multiple single batteries are connected and fixed together in a series-parallel manner. At present, the usual assembly method is to first fix the single battery in the single battery frame, and then connect and fasten them together through bolts and nuts. Because there is a reciprocating process of volume expansion and contraction during the charging and discharging process of lithium-ion batteries, the traditional bolt connection method cannot adjust the expansion pressure between the batteries for this process. charge and discharge stability. In addition, there are some side reactions in the charging and discharging process of the battery, which generates gas inside the battery, which causes the battery to bulge. When the bulge reaches a c...
