Background
In order to ensure the operating state and performance of the fuel cell stack, it is necessary to confirm that the fuel cell voltage can operate at a normal operating voltage, and at the same time, it is also necessary to monitor whether the voltage of each single cell has uniformity. If the voltage of the single cell in the fuel cell cannot be measured in real time, and thus the best time for taking protective measures is missed, the performance of the whole cell stack may be damaged or the performance of the whole cell system may be reduced. Therefore, a technique capable of detecting in real time whether or not an abnormal condition occurs in the single cell of the fuel cell is actually important.
In the conventional fuel cell, in order to read the voltage value of each unit cell in the fuel cell, as shown in fig. 1, a voltage measuring module 3 is coupled to the fuel cell 1 through a probe integration terminal 2, and a circuit board 32 in the voltage measuring module 3 must be coupled to a large number of signal transmission lines 31b in addition to an isolation signal line 31 a.
Although the conventional information bus also reduces the assembly complexity in a modularized manner, in practical applications, especially in a high-voltage fuel cell, because the number of required single cells is quite large, the number of signal transmission lines and isolation signal lines corresponding to the single cells is still quite large, and once an error occurs in an assembly sequence or an assembly failure occurs and the like, an abnormal result of an excessively high voltage occurs in the voltage measurement module due to the fact that the signal transmission lines cannot normally transmit voltage value signals, so that the entire fuel cell and the voltage measurement module are exposed to a risk of damage.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The integrated voltage measuring system 5 of the fuel cell disclosed in the present invention can be applied to a fuel cell 4 including a plurality of unit cells 41, each unit cell 41 having a wireless voltage signal, the integrated voltage measuring system 5 disclosed in the present invention includes a voltage measuring module 51 and a connecting module 52.
The voltage measuring module 51 of the integrated voltage measuring system 5 includes a wireless signal transmission unit 51a and a plurality of terminal portions 51b, the connection module 52 includes a carrier 52a and a plurality of electrical connectors 52b, the carrier 52a has a plurality of through holes 52aa and at least one fixing portion 52ab, the through holes 52aa are located in the carrier 52a, the fixing portion 52ab is connected with the carrier 52a and the fuel cell 4, the electrical connectors 52b are detachably connected in the through holes 52aa of the carrier 52a, wherein the fixing portion 52ab is a buckle, a tenon, a hook, a slider, a sliding slot or a combination thereof. Each electrical connector 52b includes a first electrical connection terminal 52ba and a second electrical connection terminal 52bb, the first electrical connection terminal 52ba is correspondingly coupled to the terminal portions 51b of the voltage measurement module 51, and the second electrical connection terminal 52bb of each electrical connector 52b is correspondingly coupled to the single cell 41 of the fuel cell 4.
First, in the connecting module 52, the carrier 52a is insulated, and for the fuel cell 4 with high voltage requirement, the number of the unit cells 41 included in the stack is usually quite large, and the distance between the unit cells 41 is relatively narrow, so as to avoid the short circuit problem caused by contact, an insulating layer 52bc is further formed on the outer surface of the electrical connector 52b, especially on the outer surface of the second electrical connector 52bb, to avoid the short circuit caused by contact between the electrical connector 52b and the adjacent unit cell 41. In order to avoid short-circuiting between the electrical connector 52b and the adjacent cell 41, the main body 52a of the connection module 52 may be formed with a plurality of insulating extensions 52ac extending along the direction of the through-hole 52aa and the cell 41.
In addition, since the connection modules 52 of the adjacent fuel cells 4 are mostly connected tightly to save space and increase the volume energy density of the assembly when the plurality of fuel cells 4 are assembled, the carrier 52a at the other end corresponding to the through hole 52aa of the connection module 52 disclosed in the present invention can be held, so that the assembly or disassembly of the connection module 52 can be directly performed by a jig or manually. In the connection module 52, the electrical connection component 52b can be designed to have different lengths and appearances according to different mechanism designs, so that the possibility of installation errors during assembly can be reduced.
It should be noted that, in the integrated voltage measurement system 5, the voltage measurement module 51 and the connection module 52 can have different mechanical connection designs according to different requirements in the electrical coupling manner, for example, the terminal portion 51B of the voltage measurement module 51 and the first electrical connection terminal 52ba of the connection module 52 can be in a pluggable connection relationship, in other words, similar to the configuration shown in fig. 4B, the terminal portion 51B of the voltage measurement module 51 can be coupled to the first electrical connection terminal 52ba of the connection module 52 in a pluggable manner, or in other configurations, the terminal portion 51B of the voltage measurement module 51 and the first electrical connection terminal 52ba of the connection module 52 are in an integrated connection relationship, for example, the terminal portion 51B of the voltage measurement module 51 and the first electrical connection terminal 52ba of the connection module 52 can be fixedly coupled by welding or other post-process manners, alternatively, the terminal portion 51b of the voltage measuring module 51 and the first electrical connection terminal 52ba of the connection module 52 may be integrally formed, in other words, the voltage measuring module 51 and the connection module 52 are both integrally formed in structure and electrical connection.
In addition, the signal transmission modes of the integrated voltage measurement system 5 and the external data transmission unit 6 can be divided into wired or wireless communication modes, for example, when the signal transmission modes of the integrated voltage measurement system 5 and the external data transmission unit 6 are wired communication modes, an isolation signal line (not shown) can be used as a coupled physical line, a synchronous Serial Peripheral Interface (SPI) can be generally adopted, and since the isolation signal element 6 is only used for transmitting digital information and does not transmit analog radio voltage signals, even if the line is accidentally dropped, an error occurs during assembly or any unexpected error occurs, the integrated voltage measurement system 5 and the fuel cell 4 are only disconnected, and the problem that the integrated voltage measurement system 5 and the fuel cell 4 are damaged due to excessively high voltage is avoided.
When the signal transmission mode of the integrated voltage measurement system 5 and the external data transmission unit 6 is a wireless communication mode, the wireless communication transmission unit 51a of the voltage measurement module 51 is directly used to receive and output a plurality of wireless voltage signals of the fuel cell 4 and also read the wireless voltage signals transmitted by the external data transmission unit 6, wherein the data transmission mode of the wireless signal transmission unit is an active wireless transmission method and/or a passive wireless transmission method, for example, the data transmission mode of the wireless signal transmission unit 51a may use active radio frequency technology, such as the existing ZIGBEE, ANT, BT, etc. as a transmission interface, or a passive radio frequency tag as a transmission interface, and when the wireless signal transmission unit 51a uses a passive transmission interface, usually, an active reader (not shown) is collocated with the outside to read back the wireless voltage signal, in other words, the wireless communication transmission unit 51a of the voltage measurement module 51 of the present invention receives the wireless voltage signal of the fuel cell 4 in a wireless communication manner, but the transmission mode with the external data transmission unit 6 is designed according to different requirements, and the purpose of data transmission is achieved by a wired or wireless communication manner.
As can be seen from the above description, since the voltage measurement module 7 receives the wireless voltage signal of each cell 41 in the fuel cell 4 by wireless communication, the problem of electrical interference caused by too high density of electronic components (such as a large number of signal transmission lines for transmitting analog signals) can be reduced, and the distance between the integrated voltage measurement system 5 and the fuel cell 4 can also be effectively shortened.
Furthermore, since the voltage measuring module 7 of the integrated voltage measuring system 5 of the present invention is integrated with the connection module 5, the power required by the voltage measuring module 7 can be directly supplied by the fuel cell 4 without additionally configuring a separate battery as a power supply.
Therefore, the integrated voltage measuring system of the fuel cell disclosed by the invention transmits the voltage value of each single cell in the fuel cell in a wireless communication mode, so that the voltage measuring module, the connecting module and the fuel cell are not required to be coupled by using signal lines, and the voltage isolation effect is effectively achieved. In addition, because the terminal of the voltage measuring module is directly coupled with the connecting module, the integrated structure can reduce the probability of error during assembly and reduce the risk of over-high voltage of the fuel cell caused by the error of line assembly. In addition, because the integrated voltage measuring system and the external data transmission unit are only coupled by the isolation signal line, even if assembly errors occur, the problem of disconnection between the voltage measuring module and the fuel cell is only caused, and the problem of damage caused by overhigh voltage is avoided. And because the integrated voltage measurement system is directly integrated in the fuel cell, the power required by the voltage measurement module is directly supplied by the fuel cell without additionally arranging an independent power supply element.
In view of the above, in the integrated voltage measurement system for a fuel cell according to the present invention, the voltage measurement module is integrated on the connection module of the fuel cell, and the voltage measurement module and the connection module are only coupled to each other in a terminal manner, and the voltage measurement module receives and transmits the wireless voltage signal in a wireless communication manner, so that the integrated voltage measurement system is assembled without using a lead wire manner, thereby reducing the occurrence probability of assembly errors, and meanwhile, since the voltage value is detected in a wireless communication manner, the situations of over-high voltage and circuit and element damage caused by assembly errors are avoided. In addition, the power source of the voltage measuring module is self-powered after the fuel cell reacts, an external power supply does not need to be additionally arranged to provide power for the voltage measuring module, and the size of the whole system can be effectively reduced.
The principles and embodiments of the present invention have been described herein using specific examples, which are provided only to help understand the method and the core concept of the present invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed. In view of the above, the present disclosure should not be construed as limiting the invention.
