System Architecture & Logic
The ZB2L3 utilizes an external resistor load to dissipate energy, calculating total capacity by integrating current over time. The onboard microprocessor automatically identifies appropriate termination voltages based on the initial battery state, while allowing manual override via tactile push-buttons. Integrated diagnostic codes (Err1: Battery voltage > 15V, Err2: Battery voltage < termination voltage, Err3: Battery cannot sustain load current) ensure immediate fault isolation during automated testing sequences.
Industrial Application
In high-volume battery pack manufacturing and refurbishment facilities, the ZB2L3 serves as a critical diagnostic node. When grading salvaged 18650 cells for secondary-life energy storage systems (ESS), technicians rely on the ZB2L3 to execute standardized discharge profiles. This isolates degraded cells with high internal resistance or diminished capacity, ensuring that only cells meeting strict operational tolerances are integrated into multi-cell arrays, thereby preventing thermal runaway and premature system degradation.
