The battery management system collector 200 collects state data such as voltage, temperature, current, insulation resistance, high-voltage interlocking and the like of the battery system 401, and then obtains the service condition of the battery through analysis of the state data, and outputs monitoring signals outwards; the battery management system controller 4021 performs optimal control on the charge and discharge process of the battery system 401 according to the monitoring signal transmitted by the battery management system collector 200, so as to utilize the energy stored in the battery system 401 to the maximum extent, thereby improving the running time of the vehicle 400 of the present utility model.

For convenience of description, in the following description of the battery management system collector 200 and the battery management system controller 4021 in the embodiments of the present utility model, the battery management system collector 200 is simply described as the collector 200, and the battery management system controller 4021 is simply described as the controller 4021.

Referring to fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of an inspection platform 300 according to an embodiment of the utility model, and fig. 3 is a schematic structural diagram of a collector 200.

Referring to fig. 2 and fig. 3, the detection platform 300 provided by the present utility model includes a connector 100 and a processor 301, wherein the connector 100 is electrically connected between the collector 200 and the processor 301, so that the processor 301 can send and receive signals to the collector 200, thereby detecting the collector 200.

During the detection process, the processor 301 outputs a status signal S1 and transmits it to the collector 200 through the connector 100. After the collector 200 analyzes the status signal S1, a monitoring signal S2 is sent and transmitted into the processor 301 via the connector 100. The monitoring signal S2 of the collector 200 is analyzed by the processor 301, so as to complete the detection of the collector 200.

As shown in fig. 3, the collector 200 includes a plurality of signal transmission terminals 201 and a plurality of functional areas 202. The signal transmission terminal 201 is configured to receive various input signals and to send the monitoring signal S2 to the outside; each functional area 202 analyzes the status data collected by the corresponding signal transmission terminal 201, converts the status data into a corresponding monitoring signal S2, transmits the monitoring signal S2 to the corresponding signal transmission terminal 201, and outputs the monitoring signal S2 via the signal transmission terminal 201. The signal transmitting terminal 201 may be constructed as a pad structure as shown in fig. 3, for example.

Since the collector 200 needs to be tested by the test platform 300 before the collector 200 is applied to the battery management system 402, the normal operation of the functional areas 202 of the collector 200 is ensured.

It will be appreciated that when the collector 200 is used in the battery management system 402, the signal transmitting terminal 201 of the collector 200 is configured to receive status data such as voltage, temperature, current, insulation resistance, high voltage interlock, etc. of the battery system 401, and is configured to send the monitoring signal S2 to the outside.

When the detection platform 300 is used to detect the collector 200, the signal transmission end 201 of the collector 200 is configured to receive the status signal S1 input by the processor 301 and send out the monitoring signal S2. The status signal S1 output by the processor 301 is various status data transmitted to the collector 200 by simulating the battery system 401 under different conditions, so as to analyze and detect the monitoring signal S2 output by the collector 200 under different conditions. The status signal S1 output by the processor 301 may simulate various status data of the battery system 401 under normal operating conditions, various status data of the battery system 401 under fault conditions, and various status data of the battery system 401 under limit operating conditions, for example. Thus, detection of collector 200 is more fully achieved.

Referring to fig. 4, an open state of the connector 100 according to an embodiment of the utility model is shown.

As shown in fig. 4, the connector 100 provided by the present utility model includes a base 10, a circuit board 20, probes 30, and plug terminals 40. The base 10 further includes a bottom plate 11 and a side wall 12, and the side wall 12 is disposed around the periphery of the bottom plate 11 and is configured to cooperate with the bottom plate 11 to form a receiving space with a certain volume so as to accommodate the collector 200.

The circuit board 20 is accommodated in an accommodating space formed by the side wall 12 and the bottom plate 11 and is fixedly connected with the base 10, a plurality of transmission lines (not shown in the figure) are arranged in the circuit board 20, one end of each transmission line is electrically connected with the probe 30 arranged on one side of the circuit board 20 away from the base 10, and the other end of each transmission line is electrically connected with the plugging terminal 40 fixed on the side wall 12, so that the plugging terminal 40 can be electrically connected with each probe 30 through the circuit board 20.

It will be appreciated that the status signal S1 input from the plug terminal 40 can be transmitted to the probe 30 via the circuit board 20 during the process of detecting the collector 200 using the detection platform 300. At the same time, the monitoring signal S2 input from the probe 30 can also be transmitted to the plug terminal 40 via the circuit board 20. That is, the plug terminals 40, the circuit board 20, and the probes 30 are connected and mated with each other to form a signal transmission line of the connector 100 of the present utility model for realizing the mutual transmission of the status signal S1 and the monitor signal S2.

Meanwhile, please refer to the connection schematic diagram of the connector 100 and the collector 200 according to an embodiment of the utility model shown in fig. 5. In order to facilitate the connection between the connector 100 and the collector 200, the base 10 is omitted in fig. 5.

As shown in fig. 5, the distribution positions of the probes 30 on the circuit board 20 correspond to the distribution positions of the signal transmission terminals 201 on the collector 200. In the process of detecting the collector 200 by using the detection platform 300, the collector 200 is fixed on the base 10 (not shown in the figure), and the probe 30 extending towards the direction away from the bottom plate 11 is contacted and conducted with the signal transmission end 201 one by one, and the signal transmission end 201 of the collector 200 is electrically connected to the plug terminal 40 in cooperation with the signal transmission line formed by the probe 30, the circuit board 20 and the plug terminal 40, so that the input of the state signal S1 of the collector 200 and the output of the monitoring signal S2 are realized through the plug terminal 40.

It will be appreciated that when the collector 200 is fixed to the base 10, the status signal S1 input from the socket terminal 40 is transmitted to the circuit board 20 and sent to the probe 30, and is conducted to the collector 200 through the contact between the probe 30 and the signal transmission terminal 201. After the collector 200 analyzes the status signal S1, a monitoring signal S2 is output, and the monitoring signal S2 is transmitted to the probe 30 via the signal transmission terminal 201, is transmitted to the plugging terminal 40 via the circuit board 20, and is then output from the plugging terminal 40. Thereby, the detection function of the collector 200 is realized.

In one embodiment, as shown in fig. 5, a plurality of plug terminals 40 are disposed on the side wall 12, and each plug terminal 40 is in communication with at least one functional area 202 (see fig. 3) of the collector 200. In the process of detecting the collector 200, a plurality of functional areas 202 of the collector 200 are mainly detected, when the status signal S1 is transmitted to the collector 200, the status signal S1 is transmitted to each functional area 202, and after being processed by each functional area 202, the monitoring signal S2 is output.

It will be appreciated that the processing of the status signal S1 by each functional area 202 is independent of each other, and in the actual detection process, there are cases where detection of a certain functional area 202 of the collector 200 is required. Therefore, when a single detection needs to be performed on a certain functional area 202, the state signal S1 can be controlled to be transmitted to the socket terminal 40 corresponding to the functional area 202, and transmitted to the corresponding functional area 202 via the probe 30, and then the monitoring signal S2 output by the functional area 202 is output via the probe 30, and transmitted to an external circuit via the corresponding socket terminal 40, so that the single detection on the functional area 202 is realized.

It can be understood that each functional area 202 on the collector 200 can analyze and process state data such as voltage, temperature, current, insulation resistance, high-voltage interlock, etc. in a targeted manner, so as to output a corresponding monitoring signal S2. Each functional area 202 may be analyzed and processed corresponding to at least one of status data such as voltage, temperature, current, insulation resistance, high voltage interlock, etc.

In one embodiment, when each functional area 202 is analyzed for only one status data. For example, when the voltage of the collector 200 needs to be detected separately, the state signal S1 output by the processor 301 is transmitted to the collector 200 through the jack terminal 40 corresponding to the voltage functional area 202, and is transmitted to the voltage functional area 202 from the signal transmitting end 201 corresponding to the voltage functional area 202, and after being analyzed and processed by the voltage functional area 202, the monitoring signal S2 of the voltage is output to the outside, and is transmitted to the processor 301, so that the detection of the voltage functional area 202 is realized. It will be appreciated that in other embodiments, each functional region 202 may also be analyzed for two or more status data, and applicant does not particularly limit this.

Referring to fig. 6, a schematic structure of a closed state of the connector 100 according to an embodiment of the present utility model is shown.

As shown in fig. 6, the base 10 further includes an upper cover 13, and the upper cover 13 is rotatably connected to the side wall 12. It can be appreciated that when the collector 200 is fixed to the base 10, the upper cover 13 and the side wall 12 are buckled with each other, so that the collector 200 is received and held in the connector 100 of the present utility model.

It can be appreciated that the position of the collector 200 relative to the connector 100 is fixed, so that the position of the signal transmission end 201 of the collector 200 is fixed relative to the probe 30, and the contact conduction between the signal transmission end 201 and the probe 30 is guaranteed based on the one-to-one correspondence between the position of the signal transmission end 201 and the position of the probe 30, so as to further ensure the electrical connection between the collector 200 and the connector 100.

On the other hand, the cooperation of the upper cover 13, the side wall 12 and the bottom plate 11 prevents the damage to the collector 200 caused by external pressure, thereby protecting the collector 200 and the rest of the structure of the connector 100 disposed in the base 10. Further, the integrity of the collector 200 and the connector 100 is ensured, thereby ensuring the electrical connection of the collector 200 and the connector 100.

In one embodiment, as shown in fig. 4, the upper cover 13 further includes a pressing member 131 having elasticity. It can be appreciated that when the upper cover 13 and the side wall 12 are fastened to each other, the pressing member 131 and the collector 200 abut against each other to be used for matching with the side wall 12, so as to achieve a holding effect on the collector 200.

Meanwhile, when the pressing member 131 is elastically deformed, the pressing member 131 applies an elastic force toward the bottom plate 11 to the collector 200 based on the structure that the pressing member 131 is the upper cover 13, thereby ensuring contact of the signal transmission end 201 of the collector 200 with the probe 30.

It will be appreciated that during the detection of the collector 200, there may be a case where the collector 200 is bent and deformed toward the side away from the base plate 11, so that the signal transmission end 201 is in poor contact with the probe 30, resulting in a short circuit. Therefore, the pressing member 131 is provided on the upper cover 13 such that the elastic force applied to the collector 200 by the pressing member 131 re-contacts the signal transmission end 201, which is in poor contact with the probe 30, with the probe, thereby ensuring the signal transmission function of the connector 100 to the collector 200 according to the present utility model.

Please refer to the schematic structure of the prior art connector 100' shown in fig. 7.

As shown in fig. 7, in the prior art, the connector 100' includes a wire harness 10' and a plug terminal 20', one end of the wire harness 10' is electrically connected to the plug terminal 20', and the other end is soldered to a signal transmission end 201 of the collector 200. In the process of detecting the collector 200, the state signal S1 input from the plug terminal 20 'is transmitted to the signal transmission terminal 201 through the wire harness 10'; after analyzing the status signal S1, the collector 200 outputs a monitoring signal S2, and the monitoring signal S2 is output from the signal transmission end 201 and transmitted to the plug terminal 20' via the wire harness 10', and is output outwards through the plug terminal 20 '.

It can be appreciated that, in the prior art, the number of the wire harnesses 10' is consistent with the number of the signal transmission ends 201 of the collector 200, and when the collector 200 is connected to the connector 100', each wire harness 10' needs to be welded to the signal transmission ends 201 one by one, so that the connection between the connector 100' and the collector 200 is relatively complicated, and the connection efficiency between the connector 100' and the collector 200 is reduced.

Meanwhile, after the detection of the collector 200 is finished, based on the welding between the wire harness 10 'and the signal transmission end 201, after the connection between the collector 200 and the connector 100' is removed, welding slag may be left on the signal transmission end 201 of the collector 200, and the collector 200 with the welding slag left may not be used continuously, thereby causing the waste of the collector 200.

On the other hand, the connector 100' of the related art does not take a protective measure for the collector 200 and the wire harness 10' of the connector 100' when the collector 200 is detected. In the detection process, there may be a phenomenon that the welding point between the wire harness 10' and the signal transmission end 201 falls off due to the external pressure, and even damage is caused to the collector 200, so that the detection result cannot reflect the actual situation of the collector 200, and even cannot obtain the detection result.

Therefore, the connector 100 of the present utility model ensures the electrical connection between the connector 100 and the collector 200 by using the contact conduction between the probe 30 and the signal transmission terminal 201, and reduces the damage of the signal transmission terminal 201 of the collector 200 caused by the electrical connection between the connector 100 and the collector 200, thereby reducing the waste of the collector 200.

Meanwhile, the connector 100 protects the collector 200 and other structures of the connector 100 arranged in the base 10 by arranging the base 10, so that the damage of external pressure to the collector 200 and other structures of the connector 100 arranged in the base 10 is avoided, and the connection effect of the collector 200 and the connector 100 is further ensured.

On the other hand, the connector 100 of the present utility model makes the probe 30 contact and conduct with the signal transmission end 201 one by one when the collector 200 is fixed on the base 10 by corresponding the arrangement position of the probe 30 and the arrangement position of the signal transmission end 201, so as to avoid one by one welding process of the wire harness 10' and the signal transmission end 201 in the prior art, thereby simplifying the connection process of the connector 100 and the collector 200 and improving the connection efficiency of the connector 100 and the collector 200 of the present utility model.

Referring to fig. 8, an exploded view of a connector 100 according to an embodiment of the present utility model is shown.

As shown in fig. 8, the side wall 12 has an inner wall 121, the inner wall 121 is used for supporting the collector 200 and positioning the collector 200, the inner wall 121 is provided with a flange 1211, and the upper surface of the flange 1211 is used for carrying the collector 200. It will be appreciated that the arrangement of the inner wall 121 of the side wall 12 is such that the position of the collector 200 within the side wall 12 is relatively fixed. Based on the fixed connection between the circuit board 20 and the base 10, the position of the circuit board 20 and the position of the side wall 12 are also relatively fixed, so that the position of the probe 30 and the position of the side wall 12 are relatively fixed.

Therefore, the positions of the signal transmission ends 201 of the collector 200 and the positions of the probes 30 are relatively fixed and correspond to each other one by one, so that contact conduction between the probes 30 and the corresponding signal transmission ends 201 is facilitated, and the connection function of the connector 100 is facilitated.

On the other hand, the provision of the flange 1211 allows the collector 200 to be placed on the upper surface of the flange 1211, thereby reducing the pressure exerted by the collector 200 on the probe 30. It will be appreciated that when the flange 1211 is not used to carry the collector 200, the weight of the collector 200 is transferred to the probe 30, potentially causing damage to the probe 30. Meanwhile, the positions of the signal transmission ends 201 based on the collector 200 are not uniformly distributed on the collector 200, and the positions of the probes 30 are not uniformly distributed. It will be appreciated that there may be a case where the collector 200 is inclined due to its own weight, and the like, thereby causing a poor contact between a portion of the signal transmission terminal 201 and the probe 30.

Thus, the provision of the flange 1211 ensures the relative flatness of the surfaces of the collector 200 and probe 30, reducing possible damage to the probe 30, thereby ensuring the connection function of the connector 100 of the present utility model.

In one embodiment, as shown in fig. 8, the connector 100 of the present utility model further includes support columns 50, where the support columns 50 are disposed on the side of the circuit board 20 provided with the probes 30, and are distributed on the periphery of the circuit board 20 and extend in a direction away from the bottom board 11. It will be appreciated that the support post 50 contacts the collector 200 when the collector 200 is secured to the base 10 and is configured to engage the side wall 12 to provide support to the collector 200.

In one embodiment, as shown in fig. 8, the base 10 further includes a support plate 14, the support plate 14 is provided with a plurality of through holes 141, and the position of each through hole 141 corresponds to the position where the conductive hole 21 and the support column 50 are provided. When the collector 200 is fixed to the base 10, the support plate 14 is disposed between the flange 1211 and the collector 200, and allows each of the probes 30 and the support columns 50 to contact the collector 200 through the through holes 141. It will be appreciated that the support plate 14 cooperates with the side walls 12 to facilitate the holding effect on the collector 200.

In one embodiment, referring back to fig. 6, the plug terminal 40 includes a plug port 41 secured to the side wall 12. Wherein the plug 41 penetrates the sidewall 12. When the collector 200 is fixed to the base 10, the status signal S1 inputted from the plug terminal 40 can be directly transmitted to the circuit board 20 (not shown) through the side wall 12. Meanwhile, the monitoring signal S2 transmitted from the collector 200 to the circuit board 20 can also be directly transmitted to the plug terminal 40 through the side wall 12. That is, the plug connector 41 fixed to the side wall is provided, which is advantageous for signal transmission between the plug connector 40 and an external circuit.

On the other hand, as for the plug terminal 40 to be used in the connector 100 of the present utility model, a plug terminal 40 of a general specification may be used so as to be connected to an external device. Referring back to fig. 5, the plug terminal 40 further includes a connecting wire 42, one end of the connecting wire 42 is electrically connected to the circuit board 20, and the other end is electrically connected to a plurality of pins 411 disposed in the plug interface 41. It can be appreciated that the jack terminal 40 is configured to transmit and receive signals to and from the collector 200 through the cooperation of the pin 411 and the connection wire 42.

Referring to fig. 9, a partial schematic view of a connector 100 according to an embodiment of the present utility model is shown.

As shown in fig. 9, the signal transmission terminal 201 of the collector 200 includes a signal input terminal 201a and a signal output terminal 201b. When the collector 200 is fixed to the base 10, each probe 30 is in contact conduction with the corresponding signal transmission terminal 201.

The signal input end 201a is electrically connected with the signal input pin 411a in the pins 411 through the probe 30, so that the status signal S1 input from the signal input pin 411a can be transmitted to the signal input end 201a through the probe 30, thereby realizing signal input to the collector 200.

Meanwhile, the signal output terminal 201b is electrically connected with the signal output pin 411b of the pins 411 through the probe 30, so that the monitoring signal S2 output from the signal output terminal 201b can be transmitted to the signal output pin 411b through the probe 30, thereby realizing signal output of the collector 200.

Thus, the connector 100 of the present utility model ensures the signal transmission function of the connector 100 of the present utility model by ensuring the connection effect of the signal input pin 411a and the signal input terminal 201a, and the connection effect of the signal output pin 411b and the signal output terminal 201b.

In one embodiment, the number of conductive vias 21 is greater than or equal to the number of probes 30. Based on the detachable connection of the probe 30 and the conductive via 21, and the position of the probe 30 corresponds to the position of the signal transmitting terminal 201 one by one. It can be appreciated that the arrangement of the conductive holes 21 greater than or equal to the number of the probes 30 enables the probes 30 to be connected with the plurality of conductive holes 21, so that the probes 30 have different positions on the surface of the circuit board 20, so as to be convenient for adjusting the positions of the probes 30 corresponding to different positions of the signal transmission terminals 201.

In one embodiment, the connector 100 of the present utility model may also be used with collectors 200 of different size scales based on the number of conductive vias 21 being greater than or equal to the number of probes 30. For example, when the conductive vias 21 on the circuit board 20 of the connector 100 of the present utility model are arranged as shown in fig. 10, the collector 200 shown in fig. 2 may be used, which is equal to the connector 100 of the present utility model in size, the collector 200 shown in fig. 11 may be used, which is similar to the connector 100 of the present utility model in size, and the collector 200 shown in fig. 12, which is smaller in size and the connector 100 of the present utility model, may be used. The applicant does not particularly limit this.

It can be understood that the signal transmission terminals 201 corresponding to different collectors 200 have various arrangements, and the arrangement of the probes 30 corresponding to the connector 100 of the present utility model on the surface of the circuit board 20 also has various arrangements when detecting different collectors 200. Therefore, the connector 100 of the present utility model enables the probes 30 corresponding to the pins 411 to be connected with the plurality of conductive holes 21, so that the connector 100 of the present utility model can realize the connection function to different collectors 200, and further the range of the collectors 200 adapted by the connector 100 of the present utility model is enlarged.
