How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
Vbank = V × Ns, Ahbank = Ah × Np, Wh = Vbank × AhInputs
| Name | Unit |
|---|---|
| Battery voltage | V |
| Battery capacity | Ah |
| Number in series | 1 |
| Number in parallel | 1 |
Outputs
| Name | Unit |
|---|---|
| Bank voltage (hero result) | V |
| Bank capacity | Ah |
| Bank energy | Wh |
| Number of batteries | 1 |
Diagnose
Observations are context. They do not pass or fail a structure. See Diagnose.
| When | Observation | Severity |
|---|---|---|
(Number in series ?? 1) > 1 | Series configuration | info |
(Number in parallel ?? 1) > 1 | Parallel configuration | info |
Assumptions
- Series strings share current. Parallel strings share current.
Provenance
- Identical matched batteries. Does not evaluate balancing, BMS, or health.
