Match Power and Heat
Balance battery, coil load, output, charging and heat for the target product life.
Coil and airflow load
Provide resistance, heating structure, airflow and liquid supply conditions across operating modes.
Charging and enclosure limits
State charging target, cell format, PCB space, enclosure materials and heat-dissipation constraints.
Available energy
Cell capacity and discharge behavior must be considered at the required output and cutoff conditions.
Output profile
Power delivery, ramp behavior and mode changes affect aerosol output and energy consumption.
Thermal accumulation
Coil, PCB, cell and enclosure temperatures should be reviewed during repeated use and charging.
Protection thresholds
Cutoff, short-circuit, low-voltage and charging protections must align with the approved hardware.
Operating States
Power & Heat Tests
Test the device during use, recovery and charging—not only at one power level.
01
Energy-use profile
Measure consumption across defined output modes and representative draw sequences.
02
Voltage and cutoff behavior
Confirm output stability and end-of-discharge behavior for the selected cell and load.
03
Temperature review
Record relevant component and surface temperatures during use and charging scenarios.
04
Protection response
Check device response to the agreed electrical and operating fault conditions.
Engineering Output
