Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] Such as figure 1 As shown, in the fuel cell system fault voltage acquisition system of the present invention, in addition to the fuel cell original voltage acquisition system, a set of fuel cell fault voltage acquisition system is added. The probe 11 can measure the voltage of a fuel cell 10, and the probe 11 can measure the voltage along the Move along the guide rail 12 to collect the voltage of each fuel cell, because this is a fault voltage collection system, so the probe 11 does not work at ordinary times, only when the fuel cell fails or the main fuel cell voltage collection system fails, the system will start operation.

[0012] Such as figure 2 As shown, cells 1, 2, 3, and 4 are the first group, and cells 5, 6, 7, and 8 are the second group. When the fuel cell voltage is collected, it is found that the second group of fuel cells contain...

Abstract

The invention relates to a fuel cell system fault voltage acquisition system, which comprises a fuel cell management system and is characterized in that a probe used for acquiring fault voltage of fuel cells is arranged along the arrangement direction of the fuel cells, and the probe can move along the arrangement direction of the fuel cells so as to acquire voltage of each fuel cell. The probe is installed on a guide rail arranged above the fuel cells and is connected with the fuel cell management system. The fuel cell system fault voltage acquisition system provided by the invention overcomes problems of incomplete voltage acquisition and indistinct fault judgment of an existing fuel cell system voltage acquisition device, and can operate in parallel with an original voltage acquisition system. The fuel cell system fault voltage acquisition system acts as a standby system, the system security can be enhanced, and fault analysis can be carried out.

Description

technical field [0001] The invention relates to a fault voltage acquisition system of a fuel cell system, which can be used as a reference backup detection system when a problem occurs in the original voltage acquisition system of a fuel cell or when a fault occurs in a fuel cell. Background technique [0002] The current fuel cell system voltage collection mostly adopts a collection method of two or more batteries. If there is a problem with one or more battery unit groups, it is impossible to confirm which battery is faulty, and it is impossible to judge the severity. If there is a problem with the collection harness or connector, and the battery voltage drops, the collection system will not be able to tell. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of incomplete voltage acquisition and unclear fault discrimination existing in the existing fuel cell system voltage acquisition device, and provide a set of fuel cel...
