Setting up the POWER-Z P240 starts with the HID interface. Connect it to your PC, open the P240 testing software, and hit "Open Device Serial Communication" to link up. In the "Aging Mode" tab, create a new project. This is your workspace where you'll define every stage of the battery cycle, from initial top-up to final drain.
For the Charging Step, select Power Mode and your target protocol, such as PD3.1. If you're testing a 140W device, dial in 28V 5A and set a safety buffer (like 6A). Pro tip: Always set a "Maximum Step Time." This acts as a fail-safe, ensuring the test continues to the next phase even if the device’s internal charging curve behaves unexpectedly.
When configuring Discharge Steps, switch to Load Mode. Mirror your requirements—say, 28V 5A—and set your cutoff conditions. Crucially, don't forget to insert Idle Steps. These cool-down periods are vital for protecting your hardware and getting consistent data, especially when jumping between high-power discharge runs.
Once your steps are locked in, move to Project Mode. Choose your sampling rate (up to 60 SPS) and loop count, then hit start. The P240 handles the rest, outputting a detailed Excel report with all your voltage, current, and energy data. Just remember: your data is only as good as your cable. Use a high-spec, E-marked cable to handle the full 240W load safely.
