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
The present invention relates to a kind of fuel cell system false voltage acquisition system, can as with reference to backup detection system when when fuel cell primary voltage acquisition system goes wrong and fuel cell breaks down.
Background technology
Current fuel cell system voltage collection, the acquisition mode of many employings binodal or multiple batteries one group, once there is battery failures, and show voltage reduction, breakdown judge is for two batteries or multiple batteries group, think that this two joint or multiple batteries unit group go wrong, any batteries can not be confirmed to be and break down, and can not the order of severity be differentiated.If because collection wire harness or joint go wrong, and show the reduction of cell voltage, acquisition system also can not differentiate.
Summary of the invention
The voltage acquisition that the object of the invention is to overcome the existence of existing fuel cell system voltage harvester is comprehensive, and the unsharp problem of fault distinguishing, provides fuel cell system false voltage acquisition system that the is a set of and parallel running of primary voltage acquisition system.
For achieving the above object, technical scheme of the present invention is: a kind of fuel cell system false voltage acquisition system, comprise fuel cell management system, above fuel cell arragement direction, be provided with the probe for fuel cell voltage acquisition, and probe can along the voltage of each joint fuel cell of fuel cell arragement direction mobile collection.
Described probe is arranged on the guide rail that fuel cell arranges above, and is connected with fuel cell management system.
When fuel cell breaks down or main fuel cell System of voltage acquisition breaks down, described fuel cell system false voltage acquisition system startup optimization.
The invention has the beneficial effects as follows: the voltage acquisition that existing fuel cell system voltage harvester exists can be overcome comprehensive, the unsharp problem of fault distinguishing, and can with the parallel running of primary voltage acquisition system.Back-up system, can enhance system security, and can carry out fault analysis.
Accompanying drawing explanation
Fig. 1 is fuel cell system false voltage acquisition system schematic diagram;
Fig. 2 is fuel cell system false voltage acquisition system application example schematic diagram.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the invention will be further described.
As shown in Figure 1, fuel cell system false voltage acquisition system of the present invention, except fuel cell primary voltage acquisition system, increase a set of fuel cell System of voltage acquisition, probe 11 can measure the voltage of a joint fuel cell 10, probe 11 can along the voltage of each joint fuel cell of guide rail 12 mobile collection, because this is false voltage acquisition system, so do not work when probe 11 is flat, only when fuel cell breaks down or main fuel cell System of voltage acquisition breaks down, this cover system just brings into operation.
As shown in Figure 2,1st, 2,3,4 batteries are first group, 5th, 6,7,8 batteries are second group, when fuel battery voltage collection finds that the fault that voltage reduces appears in the 2nd group of fuel cell comprising Section 6 fuel cell, probe 11 moves to the 5th, 6,7,8 joint fuel cells, measure and often save the voltage of fuel cell, report fuel cell management system, thus be confirmed to be Section 6 fuel cell and break down, logical superpotential height judges simultaneously is occurred which kind of fault, judge to take which kind of counter-measure by fuel cell management system.
