Supported strips: See link at bottom of page.
"Web" means the individual connections between the cells, usually 7 to 8mm
If you use individual strips, use their width
Web thickness: mm
Strip thickness: mm
Average current: A ( kW)
Peak current: A ( kW)
💡
Usually, high current is only needed for starting. For foiling, current is less.
The duration is how long the peak current is consumed.
This is needed only for thermal simulation.
Peak current duration: Seconds
💡
This is the equivalent area of conductor in series with the current flow.
So the area between the P-groups
Area between groups: mm²
💡
This is the equivalent resitance from one P-group to the next.
💡
The power lost / dissipated in the strips at average current consumption.
Power Loss Strip: W
💡
The power lost / dissipated in the cells at average current consumption.
Power Loss Cells: W
At peak current:
💡
The power lost / dissipated in the strips at peak current consumption.
Power Loss Strip: W
💡
The power lost / dissipated in the cells at peak current consumption.
Power Loss Cells: W
💡
The relation of powerloss in Cells vs Strip.
Power Loss Relation: %
Temperature rise, by thermal mass, at peak current, after the duration
💡
Temperature rise of strips, at peak current, after the duration.
ΔT Strip: K (°C)
💡
Temperature rise of cells, at peak current, after the duration.
ΔT Cells: K (°C)
Temperature rise, by radiation, at peak current, at infinite duration
💡
Temperature rise of strips, according to ANSI formula for PCB trace temperatures, calculated as an external trace
ΔT Strip: K (°C)
