Problems solved by technology

The connection between the existing CVM controller and the stack is generally inserted into the socket designed by the fuel cell through metal pins or metal socket blocks, and there are no reasonable measures to ensure that the CVM controller and the fuel cell are completely tight under harsh operating conditions. Contact, the connection between the cvm controller and the fuel cell is easy to loosen and fall off, and even cause damage to the fuel cell during installation, making the overall reliability of the stack assembly low

Abstract

The invention discloses a connecting structure of a galvanic pile and a fuel cell CVM controller and a galvanic pile assembly. The connecting structure of the galvanic pile and the fuel cell CVM controller comprises a seat body, a buffer strip and a pressing rod fixed on the galvanic pile, the seat body is provided with a first groove body for clamping the buffer strip, a second groove body for clamping a metal sheet on a battery unit of a galvanic pile, and a third groove body which is used for a wire harness of a CVM controller to pass through and is communicated with the second groove body; and the pressing rod is connected with the buffer strip. According to the connecting structure of the electric pile and the fuel cell CVM controller, the stable connection of the CVM controller and the fuel cell can be realized, so that the detection reliability of the voltage of a single cell can be improved, meanwhile, the electric pile is prevented from being damaged, and the connecting structure belongs to the technical field of electric piles.

Description

technical field [0001] The invention relates to the technical field of electric stacks, in particular to a connection structure between an electric stack and a fuel cell CVM controller and an electric stack assembly. Background technique [0002] The monolithic voltage inspection (CVM) controller is an important component to monitor the operating conditions of the fuel cell engine. The stack is composed of multiple monolithic fuel cells stacked in series. Since factors such as operating temperature, humidity, pressure, and mechanical damage directly affect the single-chip voltage of the fuel cell, the use of a single-chip voltage inspection (CVM) controller can monitor the voltage of all or part of the batteries in the entire stack in real time according to requirements, and then Accurately grasp the operating status of the stack. The connection between the existing CVM controller and the stack is generally inserted into the socket designed by the fuel cell through metal pi...
