[0044] The embodiment of the present invention provides a charging test system. Figure 1 A schematic diagram of a charging test system provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, the system includes: an electronic device 11, a switch control module 13, an output module 14 and a plurality of charging ports, for example, the plurality of charging ports include charging port 1 to charging port 8. The electronic device 11, the output module 14 and the plurality of charging ports are connected to the switch control module 13; the electronic device 11 is also connected to the device under test 15; the output module 14 is also connected to the device under test 15.

[0045] In the embodiment of the present invention, the switch control module 13 , the output module 14 and a plurality of charging ports are integrated into the charging on / off board 12 .

[0046] In the embodiment of the present invention, the device under test 15 includes a first port 16 and a second port 17 , the first port 16 is used for data transmission, and the second port 17 is used for charging; the electronic device 11 is connected to the first port 16 , and the output module 14 is connected to the second port 17 .

[0047] In the embodiment of the present invention, the first port 16 is a UART port, and the second port 17 is a USB port. For example, the USB port includes but is not limited to B-5Pin, B-4Pin, B-8Pin, B-8Pin-2×4, Micro USB or Type-C.

[0048] Each step of the embodiment of the present invention may be performed by an electronic device, which includes but is not limited to a tablet computer, a portable PC, a desktop computer, etc.

[0049] The devices under test in the embodiments of the present invention include but are not limited to smart phones, tablet computers, wearable devices, etc.

[0050] In the technical solution of the charging test system provided in the embodiment of the present invention, the electronic device, the output module and the multiple charging ports are connected to the switch control module; the electronic device is also connected to the device under test, and the output module is also connected to the device under test. The switch control module, the output module and the multiple charging ports are integrated into the charging on-off board. The device under test includes a first port and a second port, the first port is used for data transmission, and the second port is used for charging; the electronic device is connected to the first port, and the output module is connected to the second port. The charging test system of the embodiment of the present invention adopts the above structure to realize automatic switching of multiple charging ports to complete the charging test process, without relying on manual switching of multiple charging ports to complete the charging test function, thereby improving the convenience of the charging test.

[0051] The embodiment of the present invention provides a charging test method, which can be based on Figure 1 The charging test system shown in is implemented as follows, Figure 2 A flow chart of a charging test method provided by an embodiment of the present invention, such as Figure 2 As shown, the method includes:

[0052] Step 101: The electronic device obtains the current power level of the device under test.

[0053] The electronic device is electrically connected to the device under test through the UART port, so the electronic device can detect the current power of the device under test through the UART port. For example, before any charging port charges the device under test, the electronic device can obtain the current power of the device under test through the UART port.

[0054] Step 102 , the electronic device determines whether the current power level is less than a first power level threshold, if so, executes step 103 ; if not, executes step 110 .

[0055] If the electronic device determines that the current power is less than the first power threshold, it indicates that the device under test can be charged and tested; if the electronic device determines that the current power is greater than or equal to the first power threshold, it indicates that the current power of the device under test is too high and the device under test can be discharged. For example, if the first power threshold is set to 90%, when the current power is 45%, the current power is less than 90%, and the device under test can be charged and tested, the electronic device can obtain complete charging information within the set charging time; when the current power is 97%, the current power is greater than 90%, and the current power of the device under test is too high. If the device under test is charged and tested at this time, the electronic device cannot obtain complete charging information within the set charging time, and the device under test can be discharged.

[0056] Step 103: The electronic device sends an activation signal of the current charging port to the switch control module according to the charging information of the device under test when the last charging port detected charged the device under test.

[0057] The charging information includes the power level of the device under test or the charging time.

[0058] As an optional solution, the charging information includes the power of the device under test. If the charging information of the device under test reaches the set power, the electronic device sends a start signal of the current charging port to the switch control module. For example, the set power is 45%, the current charging port is charging port 2, and the power of the device under test reaches 45%, and the electronic device sends a start signal of charging port 2 to the switch control module.

[0059] As another optional solution, the charging information includes the charging time. If the charging time of the device under test reaches the set time, the electronic device sends a start signal of the current charging port to the switch control module. For example, if the set time is 5 minutes, the current charging port is charging port 3, and the charging time of the device under test reaches 5 minutes, the electronic device sends a start signal of charging port 3 to the switch control module.

[0060] Step 104: The switch control module controls the current charging port to be connected to the output module in response to the start signal of the current charging port.

[0061] The switch control module determines that the current charging port needs to be controlled to charge the device under test according to the start-up signal of the current charging port, and then controls the current charging port to be connected with the output module, so that the current charging port is electrically connected with the output module through the switch control module.

[0062] Step 105: The current charging port charges the device under test through the output module.

[0063] The device under test is connected to the output module via the USB port, so the current charging port charges the device under test via the switch control module, the output module and the USB port.

[0064] Step 106: The electronic device detects the device under test to obtain charging test information.

[0065] The charging test information includes the current charging voltage, current charging current, current battery power percentage and charging protocol type. When the charging port is charging the device under test, the electronic device can obtain the current charging voltage, current charging current, current battery power percentage and charging protocol type of the device under test through the UART port. Among them, the charging protocol type includes but is not limited to a dedicated charging port (Dedicated Charging Port, DCP), a standard downstream port (Standard Downstream Port, SDP) or a charging downstream port (Charging Downstream Port, CDP).

[0066] Step 107 , the electronic device determines whether the sequence number of the current charging port is less than or equal to the total number of the multiple charging ports. If so, step 108 is executed; if so, step 109 is executed.

[0067] If the electronic device determines that the sequence number of the current charging port is less than the total number of multiple charging ports, it indicates that there is a charging port that has not performed a charging test on the device under test; if the electronic device determines that the sequence number of the current charging port is equal to the total number of multiple charging ports, it indicates that all multiple charging ports have completed the charging test on the device under test. Figure 1 As shown, the multiple charging ports include charging port 1 to charging port 8, and the serial numbers of the multiple charging ports include 1 to 8, and the total number of the multiple charging ports is 8. For example, when the serial number of the current charging port is 3, the serial number 3 of the current charging port is less than 8, indicating that there is a charging port that has not performed a charging test on the device under test; when the serial number of the current charging port is 8, the serial number 8 of the current charging port is equal to 8, indicating that all charging ports have completed the charging test on the device under test.

[0068] Step 108 : The electronic device adds 1 to the serial number of the current charging port and executes step 103 .

[0069] When the serial number of the current charging port is 5, the electronic device adds 1 to the serial number of the current charging port, and the charging port with serial number 5 is changed to the previous charging port, and the charging port with serial number 6 is changed to the current charging port; when the serial number of the current charging port is 7, the electronic device adds 1 to the serial number of the current charging port, and the charging port with serial number 7 is changed to the previous charging port, and the charging port with serial number 8 is changed to the current charging port.

[0070] Step 109: The electronic device stops charging test.

[0071] When the electronic device determines that the sequence number of the current charging port is equal to the total number of multiple charging ports, it indicates that all multiple charging ports have completed the charging test on the device under test, and the charging test on the device under test is stopped. For example, when the sequence number of the current charging port is 8, it indicates that all of the 8 charging ports have completed the charging test on the device under test, and the charging test on the device under test is stopped.

[0072] Step 110: The electronic device sends a discharge instruction to the device under test.

[0073] The current power of the device under test is too high, so the device under test needs to be discharged to reduce the current power of the device under test.

[0074] Step 111: The device under test discharges in response to a discharge instruction, and the electronic device detects the amount of electricity of the device under test after discharge.

[0075] After receiving the discharge instruction sent by the electronic device, the device under test discharges, and the electronic device can detect the amount of electricity after the device under test is discharged.

[0076] Step 112 , the electronic device determines whether the amount of electricity after discharge is greater than a second electricity threshold value, if not, execute step 103 ; if yes, execute step 110 .

[0077] If the electronic device determines that the power after discharge is less than or equal to the second power threshold, it indicates that the power of the device under test meets the conditions for charging test and no discharge process is required; if the electronic device determines that the power after discharge is greater than the second power threshold, it indicates that the power of the device under test is too high and the device under test needs to continue to be discharged. For example, if the second power threshold is set to 10%, when the current power is 5%, the current power is less than 10%, then the power of the device under test meets the conditions for charging test and the device under test can be charged; when the current power is 45%, the current power is greater than 10%, and the device under test needs to continue to be discharged.

[0078] In the embodiment of the present invention, the first power threshold is greater than the second power threshold.

[0079] Combine the following Figure 1 , through a specific example Figure 2 The charging test method is described in detail in Figure 1 As shown, 8 charging ports are taken as an example for description, and the 8 charging ports are arranged in the order of serial numbers.

[0080] The electronic device obtains the current power of the device under test. If the current power is less than or equal to the second power threshold, the electronic device sends a start signal of the charging port 1 to the switch control module. The switch control module responds to the start signal of the charging port 1 and controls the charging port 1 to be connected with the output module. The charging port 1 charges the device under test through the output module, and the electronic device detects the device under test to obtain charging test information. After the charging port 1 charges the device under test for a set time, when the electronic device detects that the power of the device under test is higher than the second power threshold, it sends a closing signal of the charging port 1 to the switch control module to stop charging the device under test. The current power of the device under test is greater than the second power threshold, and the electronic device continues to send the start signal of the charging port 1 to the switch control module; the switch control module responds to the start signal of the charging port 1, controls the charging port 1 to be connected with the output module, and the charging port 1 charges the device under test through the output module. The electronic device detects the device under test and obtains charging test information. After charging port 1 charges the device under test for a set time, the electronic device sends a start signal of charging port 2 to the switch control module based on the charging information of the device under test when the charging port 1 is detected to charge the device under test, and charging port 1 stops charging the device under test. The switch control module responds to the start signal of charging port 2 and controls charging port 2 to be connected with the output module. Charging port 2 charges the device under test through the output module, and the electronic device detects the device under test to obtain charging test information. After charging port 2 completes charging, if the electronic device determines that the current power of the device under test is greater than or equal to the first power threshold, it sends a discharge instruction to the device under test, and the device under test discharges in response to the discharge instruction, and the electronic device detects the power of the device under test after discharge. The electronic device determines whether the power after discharge is greater than the second power threshold. If the electronic device determines that the power after discharge is greater than the second power threshold, it continues to send a discharge instruction to the device under test. If the electronic device determines that the amount of electricity after discharge is less than or equal to the second electricity threshold, the electronic device sends a start signal of charging port 3 to the switch control module according to the charging information of the device under test when the charging port 2 is detected to charge the device under test; the switch control module responds to the start signal of charging port 3, controls charging port 3 to be connected with the output module, and charging port 3 charges the device under test through the output module; the electronic device detects the device under test and obtains charging test information. The charging tests of charging ports 4 to 8 are completed in sequence according to the charging test method of charging port 3, and the charging test is stopped when charging port 8 completes charging the device under test.

[0081] In the technical solution of the charging test method provided in the embodiment of the present invention, the electronic device sends an activation signal of the current charging port to the switch control module according to the charging information of the device under test when the last charging port detected charges the device under test; the switch control module controls the current charging port to be connected with the output module in response to the activation signal of the current charging port; the current charging port charges the device under test through the output module, and the electronic device detects the device under test to obtain the charging test information; when the electronic device determines that the sequence number of the current charging port is less than the total number of multiple charging ports, the sequence number of the current charging port is increased by 1, and the electronic device continues to send the activation signal of the current charging port to the switch control module according to the charging information of the device under test when the last charging port detected charges the device under test; when the electronic device determines that the sequence number of the current charging port is equal to the total number of multiple charging ports, the charging test is stopped. The embodiment of the present invention can realize automatic switching of multiple charging ports to complete the charging test process, without relying on manual switching of multiple charging ports to complete the charging test function, thereby improving the convenience of the charging test.
