Abstract

The invention relates to a soft-packaged battery module fixing structure. The soft-packaged battery module fixing structure comprises a battery module unit and an electric core component arranged in the battery module unit; a cover plate and a top cover which are clamped and matched with the battery module unit are sequentially arranged at the upper end of the battery module unit; the left and right end of the battery module unit are provided with side pressing plates which are in screw connection with the battery module unit; the cover plate is provided with multiple strip-shaped holes which stretch out of battery polar lugs; and heat isolating sheets are arranged between the side pressing plates and the battery module unit. The soft-packaged battery module fixing structure can be combined and superposed arbitrarily to form soft-packaged battery modules with different numbers of serial and parallel connection so as to meet voltage and capacity requirements of a power battery system. Meanwhile, the soft-packaged battery module fixing structure can make a full use of the advantage of high energy density of the soft-packaged battery, the designed soft-packaged battery module fixing structure gives full consideration to the light-weight requirement, improves the energy density of the battery module and accordingly greatly improves the energy density of the system.

Description

technical field [0001] The invention belongs to the technical field of power battery PACK, in particular to a soft pack battery module fixing structure. Background technique [0002] With the reduction of the state's subsidies for electric vehicles and the link between the subsidy standard and the specific energy of the battery system, car companies have generally put forward higher requirements for the energy density of the power battery system. [0003] In this context, developing batteries with high energy density and forming a battery system with high energy density through PACK has become a major issue for battery and PACK companies. Due to the cancellation of the external metal case, the soft pack battery can have higher energy density than the square hard shell battery and 18650 cylindrical battery, so the application of soft pack batteries in electric vehicles is becoming a trend. [0004] However, the pouch battery has its own disadvantages: the pouch battery PACK ...
