Problems solved by technology

[0002] At present, various power supply manufacturers generally use multiple batteries in series or in parallel to form a battery pack when making power modules. When using multiple batteries in series or in parallel, especially for hybrid vehicles, the battery used Faced with adverse environments such as vibration and heat during the process, some battery cells in the battery pack may be overheated or deformed, which may cause accidents
[0003] In addition, the existing battery pack frame requires that the battery cells in the battery pack have the same shape and size, such as figure 1 As shown, when a battery in the battery pack is damaged, it must be replaced with the same battery
When the shape and size of the battery cells are inconsistent, such as figure 2 shown, existing battery pack frame sides are not applicable

Abstract

The invention provides a battery combination framework applicable to different shapes and sizes. The battery combination framework is particularly suitable for a lithium ion battery, the framework also can be provided with a favorable ventilation structure having a temperature and deformation detection function, a plurality of battery units are arranged between an upper convergence plate and a lower convergence plate in a honeycomb structure and are fixed by screw rods penetrating through the upper convergence plate and the lower convergence plate, the battery at different heights are locked by positive leading-out screws, elastic metal roll can be tightened or expanded by a spiral expansion body so as to fill different sizes of gaps among battery units, the battery units are prevented from inclining, and integration of a battery pack is achieved.

Description

technical field [0001] The invention relates to a battery pack frame composed of a plurality of battery cells, in particular to a battery pack frame formed by a plurality of battery cells connected in series for a hybrid electric vehicle. Background technique [0002] At present, various power supply manufacturers generally use multiple batteries in series or in parallel to form a battery pack when making power modules. When using multiple batteries in series or in parallel, especially for hybrid vehicles, the battery used Faced with adverse environments such as vibration and heat during the process, some battery cells in the battery pack may overheat or deform, which may cause accidents. [0003] In addition, the existing battery pack frame requires that the battery cells in the battery pack have the same shape and size, such as figure 1 As shown, when a battery in the battery pack is damaged, it must be replaced with a battery with the same shape. When the shape and size...
