The instruments of POWER-Z all support OTA upgrade. In the recently updated firmware version, a protocol specificDecoyFunction to improve the convenience of testing. This article makes a detailed operation analysis for this function.
Operation introduction
This time, POWER-ZKM003CThe firmware version of the tester is updated to 1.7.9. Connect the PD 3.1 140W charger to the computer terminal for operation measurement.
Device connection
Change POWER-ZKM003CThe tester connects the power supply equipment (charger) and load equipment (load meter, mobile phone, tablet and other electrical equipment), and connects with the computer through its own HID port through Type-C wire. The matching upper computer POWER-Z software can operate the charging data in real time.
Step 1: Turn on the upper computer
Download the upper computer APP on the computer end and run it. You can see the left sideKM003CThe option box of represents that the tester is correctly read. Double click it to open it. The left area displays the number of testers connected to the computer, and the right interface displays the specific values of voltage, current, and power;The middle curve is the curve display;There is a time coordinate axis below;On the far right is the operation interface for setting the start/stop conditions, sampling rate, cache depth, etc.
After upgrading the new version of firmware, you can click the red menu key (indicated by the arrow) on the operation interface“Fast charging protocol”You can enter the operation interface in one column.
Step 2: Tester connection
Open“Fast charging protocol”DecoyAfter the interface, you can see the switch icon at the upper left corner. By default, you need to manually connect the tester.
After turning on the switch button, click the yellow icon on the right interface again to trigger the protocol to ensure the safety of the charging device and prevent damage.
Click the "Power Delivery" option to enter the interface of voltage and current gear options under the protocol.
It can be seen that various gears supporting PD3.1 protocol are decoy, that is, the maximum decoy voltage and current gear is 28V 5A.
After clicking the corresponding voltage and current gear, you can see that the voltage at this time is 28V in the left display column.
At the same time, during the voltage gear deception, you can synchronously click the record button in the upper computer to record the charging test data. The two operations can be carried out synchronously without mutual interference.
UFCS Fusion Protocol
The operation steps of gear deception for UFCS fusion fast charge protocol are similar to the above PD fast charge protocol. Click to enter the internal voltage gear option.
Click the corresponding voltage and current gear again, and then debug according to the test requirements;The left display area will synchronously display the current and voltage during debugging.
Similarly, when conducting voltage gear deception, you can synchronously click the record button in the upper computer to record the charging test data. The two operations can be conducted synchronously without mutual interference.
QC Fast Charging Agreement
For charging equipment supporting QC fast charging protocol, click the protocol to enter the internal voltage gear option.
Click the corresponding voltage gear again and debug according to the test requirements.
Similarly, when conducting voltage gear deception, you can synchronously click the record button in the upper computer to record the charging test data.
FCP fast charging protocol
For charging equipment that supports FCP fast charging protocol, the operation steps are similar to those above. Click the protocol to enter the internal voltage gear option, click the corresponding voltage gear again, and then debug according to the test requirements.
SCP fast charging protocol
The charging equipment supporting SCP fast charging protocol can be debugged according to the test requirements.
AFC fast charging protocol
For charging equipment supporting AFC fast charging protocol, click the protocol to enter the internal voltage gear option, click the corresponding voltage gear again, and then debug according to the test requirements.
SFCP fast charging protocol
For charging equipment that supports the SFCP fast charging protocol, you can click the protocol to enter the internal voltage gear option, click the corresponding voltage gear again, and then debug according to the test requirements.
Summary of charging head network
The above is POWER-ZKM003CThe new host computer deception function is compatible with the mainstream fast charging protocol in the market. At the same time, the charging data can be recorded in the host computer while facilitating the voltage and current numerical debugging, which does not interfere with each other and improves efficiency.
Users can adjust the frequency of data recording according to the equipment to be tested, and can also place tests. After setting the threshold, there is no need to observe in real time. At the same time, invalid data can be avoided, and test efficiency can be improved.
