Description

Technical Field

Its main purpose is to intelligently manage and maintain each battery cell; prevent overcharging and over-discharging of batteries, and extend battery life; collect battery status information in real time, and upload the data to the backend for remote monitoring. It is one of the core subsystems of an energy storage battery system.

[0003] In existing technologies, when testing a battery management unit (BMS), testers typically need to manually adjust and simulate signals that meet the required conditions, and then manually input these simulated signals into the BMS to facilitate testing. However, this method, which relies on testers manually simulating and inputting these signals into the BMS, consumes significant manpower. Furthermore, the accuracy of manually simulated signals is low, and the testing time is long, resulting in low testing efficiency. Utility Model Content

[0018] The technical solution provided by this utility model has the following advantages:

[0019] 1. The signal testing system provided by this utility model includes a mounting base and a testing structure. The mounting base has a mounting cavity and is adapted to support the test piece. The testing structure includes a testing component and a push-pull component. The push-pull component includes a push-pull member and several plug-in members. The push-pull member is disposed on the mounting base with its push-pull end facing the test piece. All the plug-in members are disposed on the push-pull end of the push-pull member. The testing component is disposed in the mounting cavity and is electrically connected to all the plug-in members and the test piece. Under the action of external force, all the plug-in members have an inserted state and a separated state. In the inserted state, the push-pull end of the push-pull member is adapted to drive all the plug-in members closer to the test piece and insert them into the test piece. In the separated state, the push-pull end of the push-pull member is adapted to drive all the plug-in members away from the test piece and separate them from the test piece.

[0020] This signal testing system, through a test structure mounted on a mounting base, has a mounting cavity and can hold a test piece (BMS) in this embodiment. The test structure specifically includes a test component and a push-pull component. The push-pull component includes a push-pull member and several connectors. In this embodiment, the push-pull member and connectors are a push-pull arm and a probe, respectively. The push-pull member is mounted on the mounting base with its push-pull end facing the test piece, allowing it to move closer to or further away from the test piece under external force. All connectors are located on the push-pull end of the push-pull member. Thus, when the push-pull end of the push-pull member moves closer to or further away from the test piece under external force, the connectors can have two states: an engaged state and a disengaged state. In the engaged state, all connectors can be inserted into the interface on the test piece; in the disengaged state, all connectors can be inserted into the interface on the test piece. The interface is separated. Furthermore, the test component is housed within the mounting cavity and electrically connected to all connectors and the device under test (DUT). This allows the test component to input test signals to the DUT through all connectors, thus testing the DUT. In the plugged-in state, all connectors on the push-pull end of the push-pull component are plugged into all interfaces on the DUT, enabling the test component to simultaneously deliver different test signals to the DUT. This allows the DUT to complete multiple signal tests at once, improving signal testing efficiency and eliminating the need for manual testing. In the separated state, all connectors are disconnected from the interfaces on the DUT, allowing the DUT to be replaced and all connectors to be plugged into the next DUT requiring testing.

[0021] 2. The signal testing system provided by this utility model includes a test component and a power supply unit. The test component is electrically connected to all connectors so that when the connectors are in the plugged-in state, the test component inputs a test signal to the device under test. The power supply unit is electrically connected to the test component and the device under test to provide voltage. The power supply unit includes a first power supply component and a second power supply component. The first power supply component provides high voltage, and the second power supply component provides low voltage. Both the first and second power supply components are electrically connected to the test component and the device under test, respectively. A control terminal is also included. The control terminal is disposed on one side of the mounting base and is electrically connected to the test component and the device under test to monitor the test component and the device under test.

[0022] This signal testing system comprises a test component and a power supply unit. The test component generates test signals and is electrically connected to all connectors. When the connectors are plugged in, the test component can input test signals to the device under test (DUT) through all connectors. The power supply unit is electrically connected to both the test component and the DUT, providing the necessary voltage for operation. The power supply unit includes a first power supply and a second power supply. In this embodiment, the first power supply is a high-voltage programmable power supply, and the second power supply is a low-voltage programmable power supply. The first power supply provides high voltage, and the second power supply provides low voltage. Both the first and second power supplies are electrically connected to the test component and the DUT, respectively, allowing them to provide high voltage and low voltage. Since the voltages provided by the first and second power supplies are programmable, they can be within the operating voltage range of the DUT. By using a control terminal located on one side of the mounting base (in this embodiment, the control terminal is a host computer), the control terminal can be electrically connected to the test piece and the test component, thereby enabling the control terminal to monitor the status of the test component and the test piece in real time to avoid malfunctions.

[0023] 3. The signal testing system provided by this utility model further includes a mounting component, which is detachably mounted on a mounting base. The mounting component is suitable for supporting the test piece, and a push-pull assembly is mounted on the mounting component. A fixing portion is provided on the mounting component for placing the test piece. It also includes an adapter component, which is disposed within the mounting cavity and connected to an external power source. The adapter component has several adapter portions suitable for electrical connection with the test piece and the power supply unit. A switch portion is provided on the adapter component for controlling the electrical connection between the adapter component and the external power source.

[0024] This signal testing system features a detachable mounting component, which in this embodiment is a clamp, mounted on a mounting base. When the mounting component is on the base, it can support the test piece, and a push-pull assembly can be mounted on it. This allows the mounting component to be removed from the base and installed on a working mounting base of another test piece when the test piece malfunctions, thus improving testing efficiency. A fixing part, in this embodiment a fixing groove, is provided on the mounting component. When the test piece is placed on the mounting component, it can be installed within the fixing part, thus securing it to the mounting component. Furthermore, when testing different models of test pieces, the mounting component can be replaced with one having a fixing part of the same size as the replacement model to ensure the testing process can proceed normally. An adapter, which is a plug-in plate in this embodiment, is installed within the mounting cavity. This adapter connects to an external power source, enabling it to operate with voltage. The adapter has several connecting parts, which are plug holes on the plug-in plate in this embodiment. These connecting parts allow the test piece and power supply unit within the mounting cavity to be electrically connected to the external power source, thus enabling them to function properly. A switch, which is a switch button on the plug-in plate in this embodiment, controls the electrical connection between the adapter and the external power source. This allows operators to control the connection of the test piece and power supply unit solely through the switch.

[0025] 4. The signal testing system provided by this utility model further includes a connection structure, which comprises a plurality of first connectors, second connectors, and third connectors. Each first connector has two ends connected to a plug-in component and a test component, respectively. Each second connector has two ends connected to a power supply unit and a test component, respectively.

Some fifth connectors have two ends connected to a control terminal and a test component, respectively, while other fifth connectors have two ends connected to a control terminal and the test component, respectively.

[0026] This signal testing system, through a connection structure positioned between the test piece, the test component, and the push-pull component, specifically includes several first connectors, second connectors, and third connectors. In this embodiment, the first connector, second connector, and third connector are respectively a first wire harness, a second wire harness, and a third wire harness. Each first connector has its two ends connected to a plug and a test piece, respectively, so that the test piece can transmit test signals to the plug through the first connector. The two ends of the second connector are connected to a power supply unit and the test piece, respectively, so that the power supply unit can provide the voltage required for the test piece to operate. The two ends of the third connector are connected to the power supply unit and the test piece, respectively, so that the power supply unit can provide the voltage required for the test piece to operate. The connection structure also includes a fourth connector and several fifth connectors. In this embodiment, the fourth connector and the fifth connector are respectively the fourth wiring harness and the fifth wiring harness. The two ends of the fourth connector are connected to the adapter and the external power supply, respectively, so that the external power supply can provide voltage to the adapter. The two ends of some of the fifth connectors are connected to the control terminal and the test component, respectively, so that the control terminal can monitor the test component through these fifth connectors.

[0037] Example

[0038] This embodiment provides a signal testing system, such as Figure 1 As shown, the test structure includes a mounting base 1 and a test structure. The mounting base 1 has a mounting cavity and is adapted to support the test piece 2. The test structure includes a test component 31 and a push-pull component 32. The push-pull component 32 includes a push-pull member 321 and several plug-in members 322. The push-pull member 321 is disposed on the mounting base 1 and its push-pull end faces the test piece 2. All the plug-in members 322 are disposed on the push-pull end of the push-pull member 321. The test component 31 is disposed in the mounting cavity and is electrically connected to all the plug-in members 322 and the test piece 2. Under the action of external force, all the plug-in members 322 have an inserted state and a separated state. In the inserted state, the push-pull end of the push-pull member 321 is adapted to drive all the plug-in members 322 closer to the test piece 2 and insert them into the test piece 2. In the separated state, the push-pull end of the push-pull member 321 is adapted to drive all the plug-in members 322 away from the test piece 2 and separate them from the test piece 2.

[0039] The signal testing system described above, through a test structure mounted on a mounting base 1, has a mounting cavity and can hold a test piece 2. In this embodiment, the test piece 2 is a BMS. The test structure specifically includes a test component 31 and a push-pull component 32. The push-pull component 32 includes a push-pull member 321 and several connectors 322. In this embodiment, the push-pull member 321 and the connectors 322 are a push-pull arm and a probe, respectively. The push-pull member 321 is mounted on the mounting base 1, and the push-pull end of the push-pull member 321 faces the test piece. 2. The push-pull end of the push-pull component 321 is configured such that it can move closer to or further away from the test piece 2 under the action of external force. All the plugs 322 are set on the push-pull end of the push-pull component 321. Thus, when the push-pull end of the push-pull component 321 moves closer to or further away from the test piece 2 under the action of external force, the plugs 322 can have two states: a plugged state and a disconnected state. In the plugged state, all the plugs 322 can be plugged into the interface on the test piece 2, and in the disconnected state, all the plugs 322 can be disconnected from the interface on the test piece 2.

[0040] In addition, the test component 31 is disposed in the mounting cavity and is electrically connected to all the connectors 322 and the test piece 2. This allows the test component 31 to input test signals to the test piece 2 through all the connectors 322, and then test the test piece 2 through the test signals. In the plugged state, all the connectors 322 on the push-pull end of the push-pull member 321 are plugged into all the interfaces on the test piece 2. This allows the test component 31 to simultaneously send different test signals to the test piece 2 through all the connectors 322, and allows the test piece 2 to complete the testing of multiple signals at one time. This improves the signal testing efficiency of the test piece 2 and avoids the need for testers to manually test the test piece 2. In the separated state, since all the connectors 322 are separated from the interfaces on the test piece 2, the test piece 2 can be replaced, and all the connectors 322 can be plugged into the next test piece 2 that needs to be tested.

[0041] The signal testing system provided in this embodiment, such as Figure 1 As shown, the test assembly 31 includes a test piece 311 and a power supply unit 312. The test piece 311 is electrically connected to all the connectors 322 so that when the connectors 322 are in the plugged state, the test piece 311 inputs a test signal to the device under test 2. The power supply unit 312 is electrically connected to the test piece 311 and the device under test 2 to provide voltage.

[0042] The signal testing system described above includes a test component 31, comprising a test element 311 and a power supply unit 312. The test element 311 generates a test signal and is electrically connected to all connectors 322. When the connectors 322 are in the plugged-in state, the test element 311 can input a test signal to the device under test 2 through all connectors 322. The power supply unit 312 is electrically connected to the test element 311 and the device under test 2, thereby providing the voltage required for operation to the test element 311 and the device under test 2.

[0043] The signal testing system provided in this embodiment, such as Figure 1 As shown, the power supply unit 312 includes a first power supply component 3121 and a second power supply component 3122. The first power supply component 3121 is used to provide high voltage electricity, and the second power supply component 3122 is used to provide low voltage electricity. Both the first power supply component 3121 and the second power supply component 3122 are electrically connected to the test component 311 and the test component 2, respectively.

[0044] The signal testing system with the above-described structure includes a power supply unit 312 comprising a first power supply component 3121 and a second power supply component 3122. In this embodiment, the first power supply component 3121 and the second power supply component 3122 are respectively a high-voltage programmable power supply and a low-voltage programmable power supply. This allows the first power supply component 3121 to provide high voltage and the second power supply component 3122 to provide low voltage. Furthermore, both the first power supply component 3121 and the second power supply component 3122 can be electrically connected to the test component 311 and the test component 2, respectively. This allows the first power supply component 3121 and the second power supply component 3122 to provide high voltage and low voltage to the test component 311 and the test component 2, respectively. Since the voltages provided by the first power supply component 3121 and the second power supply component 3122 are programmable, the voltages provided by the first power supply component 3121 and the second power supply component 3122 can be within the operating voltage range of the test component 2.

[0045] The signal testing system provided in this embodiment, such as Figure 1 As shown, it also includes a control terminal, which is located on one side of the mounting base 1. The control terminal is electrically connected to the test component 31 and the test piece 2 to monitor the test component 31 and the test piece 2.

[0046] The signal testing system described above uses a control terminal located on one side of the mounting base 1. In this embodiment, the control terminal is a host computer. The control terminal can be electrically connected to the test piece 2 and the test component 31, thereby enabling the control terminal to monitor the status of the test component 31 and the test piece 2 in real time to avoid malfunctions.

[0047] The signal testing system provided in this embodiment, such as Figure 1As shown, it also includes a mounting component 4, which is detachably mounted on the mounting base 1. The mounting component 4 is adapted to support the test piece 2, and the push-pull assembly 32 is mounted on the mounting component 4.

[0048] The signal testing system described above uses a detachable mounting component 4 mounted on the mounting base 1. In this embodiment, the mounting component 4 is a clamp. When the mounting component 4 is mounted on the mounting base 1, it can support the test piece 2, and the push-pull assembly 32 can be mounted on the mounting component 4. Thus, if the test component 31 in the mounting cavity malfunctions, the mounting component 4 can be removed from the mounting base 1 and mounted on the mounting base 1 of another test component 31 that is functioning normally to test the test piece 2, which helps to further improve testing efficiency.

[0049] The signal testing system provided in this embodiment, such as Figure 1 As shown, the mounting part 4 has a fixing part 41, which is used to place the test piece 2.

[0050] The signal testing system described above uses a fixing part 41 provided on the mounting part 4. In this embodiment, the fixing part 41 is a fixing groove. When the test piece 2 is placed on the mounting part 4, the test piece 2 can be installed in the fixing part 41. In this way, the test piece 2 can be fixed on the mounting part 4 by the fixing part 41. When testing different models of test pieces 2, the test piece 2 can be adapted by replacing the mounting part 4 with a fixing part 41 of the same size as the replacement model, so that the testing process can proceed normally.

[0051] The signal testing system provided in this embodiment, such as Figure 1 As shown, it also includes an adapter 5, which is disposed in the mounting cavity and connected to an external power source. The adapter 5 has several adapter portions 51 that are suitable for electrical connection with the test piece 311 and the power supply unit 312.

[0052] The signal testing system described above, through the adapter 5 set in the mounting cavity, which in this embodiment is a plug plate, can be connected to an external power source, thereby enabling the adapter 5 to have voltage. At the same time, the adapter 5 has several adapter parts 51, which in this embodiment are plug holes on the plug plate, so that the test piece 311 and the power supply unit 312 in the mounting cavity can be electrically connected to the external power source through the adapter parts 51, thus enabling the test piece 311 and the power supply unit 312 to work normally.

[0053] The signal testing system provided in this embodiment, such as Figure 1 As shown, the adapter 5 is provided with a switch 52, which is used to control the electrical connection between the adapter 5 and the external power source.

[0054] The signal testing system with the above structure, by setting a switch part 52 on the adapter 5, which in this embodiment is a switch button on the plug plate, the switch part 52 can control the electrical connection between the adapter 5 and the external power supply, so that the operator only needs to use the switch part 52 to control the electrical connection between the test piece 311 and the power supply unit 312 and the external power supply.

[0055] The signal testing system provided in this embodiment, such as Figure 1 As shown, it also includes a connection structure, which includes a plurality of first connectors, second connectors and third connectors. The two ends of any first connector are respectively connected to a plug 322 and a test piece 311. The two ends of the second connector are respectively connected to the power supply unit 312 and the test piece 311. The two ends of the third connector are respectively connected to the power supply unit 312 and the test piece 2.

[0056] The signal testing system described above utilizes a connection structure between the test piece 2, the test component 31, and the push-pull component 32. This connection structure specifically includes several first connectors, second connectors, and third connectors. In this embodiment, the first, second, and third connectors are respectively a first wiring harness, a second wiring harness, and a third wiring harness. Each first connector's two ends are connected to a connector 322 and a test piece 311, respectively, enabling the test piece 311 to transmit test signals to the connector 322 via the first connector. The two ends of the second connector are connected to a power supply unit 312 and the test piece 311, respectively, allowing the power supply unit 312 to provide the voltage required for the test piece 311's operation. The two ends of the third connector are connected to the power supply unit 312 and the test piece 2, respectively, enabling the power supply unit 312 to provide the voltage required for the test piece 2's operation.

[0057] The signal testing system provided in this embodiment, such as Figure 1 As shown, the connection structure also includes a fourth connector and a fifth connector. The two ends of the fourth connector are connected to the adapter 5 and the external power supply, respectively, so that the external power supply provides voltage to the adapter 5. The two ends of part of the fifth connector are connected to the control terminal and the test component 31, respectively, and the two ends of another part of the fifth connector are connected to the control terminal and the test piece 2, respectively.

[0058] The signal testing system with the above-described structure further includes a fourth connector and several fifth connectors through the connection structure. In this embodiment, the fourth connector and the fifth connector are respectively the fourth wiring harness and the fifth wiring harness. The two ends of the fourth connector are connected to the adapter 5 and the external power supply, respectively, so that the external power supply can provide voltage to the adapter 5. The two ends of some of the fifth connectors are connected to the control terminal and the test component 31, respectively, so that the control terminal can monitor the test component 31 through these fifth connectors. The two ends of another part of the fifth connectors are connected to the control terminal and the test piece 2, respectively, so that the control terminal can monitor the test piece 2 through these fifth connectors.

[0059] The signal testing system provided by this utility model includes a test structure mounted on a mounting base 1. The mounting base 1 has a mounting cavity and can hold a test piece 2, which in this embodiment is a BMS. The test structure specifically includes a test component 31 and a push-pull component 32. The push-pull component 32 includes a push-pull member 321 and several plug-in members 322. In this embodiment, the push-pull member 321 and the plug-in members 322 are a push-pull arm and a probe, respectively. The push-pull member 321 is mounted on the mounting base 1, and the push-pull member 321... The push-pull end of the push-pull member 321 is positioned towards the test piece 2, allowing it to move closer to or further away from the test piece 2 under external force. All the connectors 322 are located on the push-pull end of the push-pull member 321. Thus, when the push-pull end of the push-pull member 321 moves closer to or further away from the test piece 2 under external force, the connectors 322 can have two states: an engaged state and a disengaged state. In the engaged state, all connectors 322 can be inserted into the interface on the test piece 2. In the disengaged state, all connectors 322... The test component 31 is detachable from the interface on the test piece 2. Furthermore, the test component 31 is located within the mounting cavity and is electrically connected to all the connectors 322 and the test piece 2. This allows the test component 31 to input test signals to the test piece 2 through all the connectors 322, thereby testing the test piece 2. In the plugged-in state, all the connectors 322 on the push-pull end of the push-pull member 321 are plugged into all the interfaces on the test piece 2. This allows the test component 31 to simultaneously transmit different test signals to the test piece 2 through all the connectors 322, enabling the test piece 2 to complete multiple signal tests at once. This improves the signal testing efficiency of the test piece 2 and avoids manual testing by the tester. In the detached state, since all the connectors 322 are separated from the interface on the test piece 2, the test piece 2 can be replaced, allowing all the connectors 322 to be plugged into the next test piece 2 that needs to be tested.
