In the charging performance testing stage of the new energy vehicle, a national standard recommended direct current disconnect box (GBT-DC BOB) is generally connected between the vehicle and the charging pile to provide controlled power and/or signals to the vehicle so as to inject various charging faults into the vehicle, and then the feedback data is read and the state of the vehicle is determined, and finally whether the performance of the vehicle meets the national standard recommended direct current charging performance standard is determined.

The inventors of the present application have discovered that there are a number of disadvantages with existing dc breakout boxes, including but not limited to: the manual operation is mainly carried out on site by testers, so that the use is inconvenient, the testing efficiency is low, and human errors are easily introduced; only the on/off of the signal line can be controlled, and the on/off of the power line cannot be controlled; the resistance value can not be changed to meet the requirements of the direct current test standard recommended by the national standard; the low voltage direct current (LV DC) voltage value cannot be changed to meet the requirements of the DC test standard recommended by the national standard.

Accordingly, the inventors of the present application propose an improved dc charging performance test apparatus for a vehicle, which can solve the above-mentioned disadvantages of the above-mentioned conventional dc disconnect box.

Fig. 1 schematically shows a structural schematic diagram of a dc charging performance test apparatus 10 for a vehicle according to an embodiment of the present disclosure.

As shown in fig. 1, the dc charging performance test apparatus 10 for a vehicle may include: a charging input 120 for connecting to an external power device to obtain power from the external power device; and a charging output 130 for connecting to a vehicle to charge the vehicle. When it is required to connect the dc charging performance test apparatus 10 between the charging pile and the vehicle to be charged, the charging gun of the charging pile may be connected to the charging input terminal 120, and the charging output terminal 130 may be connected to the charging inlet of the vehicle. In some embodiments according to the present disclosure, the charging input 120 may be, for example, a charging socket capable of plugging a charging gun, and the charging output 130 may be, for example, a charging gun. Note that both the power drawn by the charging input 120 and the power provided by the charging output 130 are in the form of direct current.

Referring to fig. 1, the dc charging performance test apparatus 10 for a vehicle may further include a national standard dc charging guide circuit 140 connected between the charging input terminal 120 and the charging output terminal 130. Since the dc charging involves the use of a higher dc voltage, which may cause danger, meeting the national recommended standards is a crucial requirement for dc charging guidance circuits. The national standard direct current charging guide circuit 140 according to an embodiment of the present disclosure is a circuit for implementing a control guide function of direct current charging between a charging pile and a vehicle to be charged, which strictly satisfies a national recommended standard, and may include at least one signal line.

The dc charging performance test apparatus 10 for a vehicle may further include at least one power line 150 connected between the charging input terminal and the charging output terminal. Note that in the present disclosure, the power line 150 refers to a line for supplying the main power to the vehicle battery, and the signal line in the national standard dc charging guidance circuit 140 may cover all other lines required for charging, other than the power line 150, such as a circuit for providing a control signal, a line for providing communication, and/or a line for providing an auxiliary voltage, and the like.

With continued reference to fig. 1, the dc charging performance test apparatus 10 for a vehicle may further include a control circuit 100 coupled to a national standard dc charging boot circuit 140 and at least one power line 150, and including a main control board 110. The master control board 110 may include a communication module 112 to enable the master control board 110 to receive a first set of control signals through the communication module 112. In a preferred embodiment, the communication module may comprise a CAN bus, for example. The dc charging performance test apparatus 10 for a vehicle may further include a touch panel 160. The touch panel 160 may be coupled to the main control board 110, so that the main control board 110 can receive a second set of control signals input by a user through the touch panel 160. In a preferred embodiment, the main control board 110 may be provided with a dedicated interface for connecting the touch panel 160. In a preferred embodiment, the touch panel 160 may be disposed on the housing of the dc charging performance testing apparatus 10, for example, so as to be convenient for the tester to use. Those skilled in the art will understand that the connection lines in fig. 1 are only used for schematically illustrating the connection/coupling relationship between the respective modules, and are not intended to constitute any limitation on the specific connection/coupling manner (for example, it is not intended that such a connection line necessarily exists between the connected/coupled modules or only one connection line exists or no other component is included in the connection line, etc.). In embodiments according to the present disclosure, the connected/coupled modules may be connected/coupled to each other in any suitable manner.

The control circuit 100 may control the operation of the dc charging performance testing device 10 according to the first set of control signals and/or the second set of control signals. That is, the control circuit 100 may control the operation of the device 10 only according to a first set of control signals received by the main control board 110 through the communication module 112 and remotely input by a tester, may control the operation of the device 10 only according to a second set of control signals received by the main control board 110 through the touch panel 160 and input by a tester in the field, and may control the operation of the device 10 according to a combination of the two sets of control signals.

With continued reference to fig. 1, in some embodiments according to the present disclosure, the master card 110 may also include a memory 114. The memory 114 stores a control program executable by the main control board 110. The main control board 110 may execute a control program according to the first set of control signals and/or the second set of control signals to control the operation of the dc charging performance testing apparatus 10.

According to the national standard recommendation standard, the direct current charging performance test relates to various different test items. In the existing dc charging performance testing device, a plurality of manually operated control components are usually provided, and the testing personnel manually operate the control components at a testing site to perform various tests one by one. This results in a high expenditure of manpower on the one hand and a low efficiency of the test on the other hand. Therefore, in the embodiment according to the present disclosure, a control program may be provided in advance in the control board 110 of the control circuit 100, and then the program may be specifically set according to the acquired control signal, so as to implement an automatic operation of the dc charging performance test.

As described above, the control signals may be obtained through two channels, one is to receive a first set of control signals from the outside through the communication module 112 of the main control board 110, which enables a tester to remotely control the operation of the dc charging performance testing apparatus 10; the other is that the tester manually inputs the second set of control signals through the touch panel, which enables the tester to flexibly adjust the operation of the dc charging performance testing apparatus 10 in the field. Those skilled in the art will appreciate that either the first set of control signals or the second set of control signals may be used alone or in combination. In a preferred embodiment, a plurality of different tests can be preset by the control program, and then the tester inputs corresponding test parameters by the first set of control signals and/or the second set of control signals, and then the apparatus 10 automatically completes the plurality of tests in sequence. The dc charging performance testing apparatus 10 according to the present disclosure provides great convenience for testing, including but not limited to: the method has the advantages of avoiding complex manual operation, simplifying the test flow, allowing remote control, improving the flexibility of the test, improving the test efficiency and the like.

In some embodiments according to the present disclosure, the master control board 110 may be further configured to: the test state feedback signal and/or the test result data are transmitted to the outside through the communication module 112 and/or displayed through the touch panel 160. Under the condition of sending a test state feedback signal and/or test result data to the outside through the communication module 112, a tester can remotely know the test state and/or result; under the condition that the test state feedback signal and/or the test result data are displayed through the touch panel 160, a tester can intuitively know the test state and/or the test result through the touch panel, so that the test flow is greatly simplified, and the test efficiency is improved.

By adopting the dc charging performance testing device 10 provided by the present disclosure, a tester can provide a control command for setting a corresponding control program through remote transmission or input of the touch panel 160, and then obtain a test state feedback signal and/or test result data through remote reception or reading of the touch panel 160, thereby realizing automation of a dc charging performance testing process of a vehicle, which not only saves manpower, but also greatly improves testing efficiency.

With continued reference to fig. 1, in some embodiments according to the present disclosure, the control circuit 100 may further include a relay module 170, and the relay module 170 may be coupled to the master board 110. The main control board 110 may control on/off of at least one signal line in the national standard dc charging guidance circuit 140 through the relay module 170, so as to inject a path/open fault into the national standard dc charging guidance circuit 140. The main control board 110 may also control the on/off of at least one power line 150 through the relay module 170. In a preferred embodiment, the relay module 170 may include, for example, a relay board card.

In the embodiment according to the present disclosure, the relay module 170 may include a plurality of relays, which may be used as switches in various circuit configurations, for example, as switches in signal lines provided in the national standard dc charging guide circuit 140, as switches for controlling high-current high-voltage contactors in power lines, or as switches in other components in the dc charging performance test apparatus 10, so that the main control board 100 may implement various controls through the switches.

Because the voltage adopted by the direct current charging is high, and the control difficulty is high, the existing direct current charging performance test equipment cannot control the connection/disconnection of a power line generally. In some embodiments according to the present disclosure, each of the at least one power lines 150 may include a high current and high voltage contactor 152, such that the control circuit 100 can control the power lines to be turned on/off through the high current and high voltage contactor 152, thereby achieving more sophisticated control over the dc charging performance test. In a preferred embodiment, the main control board 110 controls the on/off of the high-current high-voltage contactor 152 through a relay in the relay module, so as to control the on/off of the power line.

With continued reference to fig. 1, in some embodiments according to the present disclosure, the dc charging performance test apparatus 10 may further include a voltage acquisition module 180, the voltage acquisition module 180 being coupled to the control circuit 100 and the national dc charging guidance circuit 140 for varying the auxiliary voltage provided to the national dc charging guidance circuit 140 under the control of the control circuit 100 to inject an auxiliary voltage fault to the national dc charging guidance circuit 140. According to the national standard for direct current charging, it is generally necessary to supply an auxiliary voltage of, for example, 12V to a vehicle to be charged, and to require the auxiliary voltage to satisfy a precision range of, for example, 11.6V to 12.4V. In practice, however, auxiliary voltages outside this range may occur, so that the state of the vehicle to be charged in special situations needs to be tested. In an embodiment according to the present disclosure, the voltage acquisition module 180 may provide a variable auxiliary voltage to test the response of the vehicle to be charged to various auxiliary voltages. The voltage collection module 180 may also feed back the actual voltage provided to the vehicle to the control circuit 100 so that the tester knows the actual auxiliary voltage for testing. In a preferred embodiment, the voltage acquisition module 180 may be connected to the control board 100 through an I/O interface on the control board 110, and may also be connected to a relay in the relay module 170. In a preferred embodiment, the voltage acquisition module 180 may include an adjustable dc power supply.

With continued reference to fig. 1, in some embodiments according to the present disclosure, the dc charging performance test apparatus 10 may further include an adjustable resistance module 190, the adjustable resistance module 190 being coupled to the control circuit 100 and the national dc charging guidance circuit 140 for changing a guidance resistance provided to the national dc charging guidance circuit 140 under the control of the control circuit 100 to inject a guidance resistance fault to the national dc charging guidance circuit 140. In a preferred embodiment, the adjustable resistor module 190 may be connected to the control board 100 through an I/O interface on the control board 110, and may also be connected to a relay in the relay module 170. In a preferred embodiment, the adjustable resistor module 190 comprises an adjustable resistor board, for example.

In the existing direct current charging performance test equipment, the resistance value cannot be changed to meet the requirements of the direct current test standard recommended by the national standard, and the low voltage direct current (LV DC) voltage value cannot be changed to meet the requirements of the direct current test standard recommended by the national standard. By adopting the direct current charging performance test device 10 provided by the disclosure, a tester can change the resistance value through the adjustable resistance module 190, can change the low voltage direct current (LV DC) voltage value through the voltage acquisition module 180, and can also provide a control command for controlling the voltage acquisition module 180 and/or the adjustable resistance module 190 through remote transmission or input of the touch panel 160, thereby realizing the automation of the test and greatly improving the test efficiency.

In the dc charging performance test process, when the data fed back by the charging performance test device is inconsistent with the corresponding data read from the vehicle, third party verification is required. To facilitate third party verification, the dc charging performance test device 10 for a vehicle according to an embodiment of the present disclosure may further include a plurality of interfaces 200 provided on the device housing, the plurality of interfaces being connected to the national standard dc charging guidance circuit 140 and/or the at least one power line 150 for a tester to obtain third party test data. Due to the design, third-party test data can be conveniently obtained, and the test efficiency is greatly improved.

In some embodiments according to the present disclosure, the dc charging performance test device 10 may be, for example, a breakout box BOB. In a preferred embodiment, the touch panel 160 and the interface 200 may be disposed on a side of the housing of the termination box for ease of use.

In some embodiments according to the present disclosure, the dc charging performance testing device 10 itself may be powered by 220V ac, for example.

Through adopting the direct current that this disclosure provided to charge capability test equipment, not only can overcome aforementioned shortcoming of current direct current charge capability test equipment, can also realize the remote control and the automated operation of test under the condition of greatly using manpower sparingly operation to effectively improve efficiency of software testing and test accuracy.
