System Structure
The testing system includes upper computer software, middle computer control, bidirectional AC/DC conversion and bidirectional DC/DC control. During charging, the system draws power from the grid and charges the battery pack. During discharging, the energy regenerative module feeds energy back to the grid to improve energy efficiency.
Software and Data Management
The upper computer software supports device start, stop, pause, test step editing, channel monitoring, data collection and report export. Operators can view channel status, compare curves and export test data to CSV or Excel for battery quality analysis.
