Engineering module
Battery & EV Systems
Closed-form or FEM estimates without a specific design code claim. Applies recommended default units when you change standard; unit dropdowns stay fully editable.
Design workflow
Design / Check / Select for Battery & EV Systems
Define targets in the inputs column, compare candidates in Select mode, and apply a sizing result before running a detailed check.
Use the Workflow mode control in the inputs column to switch between Check, Design, and Select.
Verify the geometry and loads already entered in the calculator.
Coolant temperature-rise sweep for pack ohmic heat rejection.
| Option | Size | Util. | Margin | Status | Governing | Detail |
|---|---|---|---|---|---|---|
| ΔT = 4 K | ΔT = 4 K | 0.00 | — | pass | design target | flow 0.000 kg/s |
| ΔT = 6 K | ΔT = 6 K | 0.00 | — | pass | design target | flow 0.000 kg/s |
| ΔT = 8 K | ΔT = 8 K | 0.00 | — | pass | design target | flow 0.000 kg/s |
| ΔT = 10 K | ΔT = 10 K | 0.00 | — | pass | design target | flow 0.000 kg/s |
| ΔT = 12 K | ΔT = 12 K | 0.00 | — | pass | design target | flow 0.000 kg/s |
| ΔT = 15 K | ΔT = 15 K | 0.00 | — | pass | design target | flow 0.000 kg/s |
Recommendation: ΔT = 4 K is the first passing candidate with design target governing.
- Computed from live calculator inputs via module design registry.
- utilization = demand / capacity (module-specific)
| Candidate | Basis | Pass criteria | Tradeoff |
|---|---|---|---|
| Research screen | Fast estimate | Flag risks | Lowest detail |
| Preliminary design | Balanced assumptions | Pass expected | Needs verification |
| Conservative design | Margin-first | High reserve | Heavier/costlier |
Candidate columns to calculate: Configuration, Margin, Risk, Next linked check.
- Cryogenic properties
- Vacuum conductance
- Magnet constants
- Battery/hydrogen safety references
- Cell formats
- Busbar current density
- Coolants
- UL/SAE/ISO safety references
- Advanced systems need assumptions shown prominently because coupled physics can dominate simple checks.
