Description

Battery stacking module with assembling and arranging functions for new energy automobile

Technical Field

The invention relates to the technical field of new energy automobiles, in particular to a battery stacking module with an assembling and arranging function for a new energy automobile.

Background

An important benefit of utilizing a fuel cell to convert fuel into usable electricity through an electrochemical reaction is that it is achieved without relying on combustion as an intermediate step. As such, fuel cells have several environmental advantages over Internal Combustion Engines (ICEs) for propulsion and related prime mover applications. In a typical fuel cell, such as a proton exchange membrane or polymer electrolyte membrane (PEM in either case) fuel cell, a pair of catalytic electrodes are separated by an ion transport medium, such as nafion (tm), where they are collectively referred to as a Membrane Electrode Assembly (MEA). When a gaseous reducing agent, such as hydrogen, is introduced and ionized at the anode and then passed through the ion-transport medium such that it reacts electrochemically in combination with a gaseous oxidizing agent, such as oxygen, introduced through the other electrode (cathode), this combination of reactants forms water as a byproduct. The electrons released in the ionization of hydrogen travel to the cathode in the form of Direct Current (DC) through an external circuit, which typically includes a load (e.g., an electric motor) in which useful work can be performed. The power generation generated by such DC power flow can be increased by incorporating a plurality of such cells into a larger current generating assembly. In one such configuration, the fuel cells are connected along a common stacking dimension (much like playing cards) to form a fuel cell stack. From the viewpoint of energy conservation and ecological environment protection, fuel cells are the most promising power generation technology, and among them, new energy vehicles have a high utilization rate.

Chinese patent granted publication No. CN106025321B is a reference piece design for fuel cell stack and collision protection. Systems and methods for aligning and reducing relative movement between adjacent fuel cells in a fuel cell stack are provided. The inter-cell cooperation of the fuel cells along the stacking dimension is enhanced by one or more datum members placed along the edges of the bipolar plates that form part of the cell housing assembly. The datum members are shaped along a thickness substantially coincident with the cell stacking dimension to avoid misalignment between adjacent stacked cells that would otherwise occur due to the occurrence of significant acceleration along the dimension defining the major surfaces of the plates, cells and their respective components. By having the datum integrally formed with a plurality of stacked cells, the need to secure a separate tab to each plate is avoided.

A fuel cell device according to chinese patent No. CN105591144B, comprising: a battery pack (102S); a case (500), the case (500) including a cover portion (503) that covers one of side surfaces of the battery pack (102S) in the stacking direction; an end plate (190), the end plate (190) being connected to one end of the cover portion (503) in the stacking direction; and a fastening member (300), the fastening member (300) extending parallel to the stacking direction on the opposite side of the battery pack (102S) from the cover (503), the fastening member (300) including one end in the stacking direction connected to the end plate (190) and the other end in the stacking direction connected to the case (500), and the fastening member (300) fastening the battery pack (102S), the end plate (190), and the case (500) to each other. The thermal expansion coefficient of the cover part (503) is larger than that of the fastening part (300)
