Here is what PBPF-IDO produces for a premium passenger EV scenario. Your own results will reflect your own vehicle parameters.
Sample Scenario
Premium passenger EV, 500 km range
VEHICLE MASS
1,900 kg
TARGET RANGE
500 km
PEAK POWER
200 kW
CYCLE LIFE
2,000 cycles
Recommended Pack
NMC 811
Current premium EV standard. Highest volumetric energy density at production-ready scale (TRL 9).
Lightest Pareto-optimal chemistry that meets all range, power, and cycle-life constraints for this scenario.
PACK MASS
425 kg
INSTALLED ENERGY
72.2 kWh
PACK COST
£6,859
Binding Constraint & Top Engineering Lever
Aerodynamic drag dominates this design
At a 110 km/h cruise speed, aerodynamic drag is the largest single contributor to pack mass. The top actionable engineering lever is the drag coefficient: a 10% reduction in Cd saves approximately 25 kg of pack mass and £400 in pack cost.
PBPF-IDO computes the full sensitivity ranking for all input parameters including mass, drag, drivetrain efficiency, rolling resistance, and frontal area. The complete sensitivity output is available inside the portal.
Pareto Frontier
Of five candidate chemistries evaluated, three meet the 200 kW peak power requirement. Pareto-optimal chemistries are highlighted.
| RANK | CHEMISTRY | PACK MASS | PACK COST | PARETO |
|---|---|---|---|---|
| 1 | NMC 811 | 425 kg | £6,859 | |
| 2 | NCA | 452 kg | £7,220 | |
| 3 | LFP | 621 kg | £5,415 |
Solid-state (Li-metal) and Li-S chemistries were evaluated but do not yet deliver the 200 kW peak power required for this vehicle at production-ready TRL levels.

Designing a battery pack for an electric vehicle is a problem with too many moving parts to solve in your head or on paper. The engineer has to balance five things at once: how far the vehicle needs to go, how much power it needs to deliver, how much the battery is allowed to weigh, how much it can cost, and how many years it has to last. Push any one of those harder and another usually gets worse. A heavier battery gives more range but raises cost and stresses the chassis. A cheaper chemistry lasts longer but cannot deliver as much peak power. A more advanced chemistry weighs less but can cost four times more and is harder to source.
PBPF-IDO does the maths across all five constraints and all five candidate chemistries simultaneously, then tells the engineer which combination produces the lightest pack that meets every requirement. It also identifies the single design choice that would deliver the biggest improvement if the engineer could change it. That second output, which battery engineers call binding-constraint sensitivity, is the part that saves real time.
All of this happens in about two seconds, in any web browser, with no installation required.
How it works
Three coupled layers, solved in one pass
Layer A: Vehicle Energy Demand
PBPF-IDO computes the energy your vehicle actually needs at the wheels and at the battery, accounting for mass, drag, rolling resistance, drivetrain efficiency, auxiliary loads, and your target range. This is the foundation of every pack design decision.
Layer B: Cell Chemistry Vector
Five calibrated chemistries (LFP, NMC811, NCA, sulfide solid-state with Li-metal anode, and stabilised Li-S) are evaluated against your vehicle parameters in parallel, producing seven figures of merit per chemistry: energy, power, cycle life, cost, mass, volume, and TRL.
Layer C: Pack Architecture Search
PBPF-IDO ranks all viable cell-chemistry-and-pack combinations on a Pareto frontier and identifies the lightest pack that meets every constraint, including thermal, safety, and crash margins. The recommended pack is highlighted with full justification.
Who PBPF-IDO is built for
PBPF-IDO is built for any organisation designing electric vehicles or battery packs that does not have a fifty-person internal software team. The first wave of users falls into eight clear groups.
Adding these groups together, the addressable population of engineers and researchers who would benefit directly from PBPF-IDO numbers between 25,000 and 40,000 worldwide, across more than 1,000 organisations in approximately 30 countries.
What makes PBPF-IDO unique
Integrated multi-physics, not stitched-together tools
Plenty of tools exist for vehicle dynamics, plenty exist for cell chemistry, plenty exist for pack architecture. PBPF-IDO is the first commercially available tool that combines all three into a single coupled optimisation, eliminating the manual transfers between separate tools that create errors and miss critical design tradeoffs.
Binding-constraint sensitivity built in
Other tools tell the engineer the answer. PBPF-IDO tells the engineer the answer plus a ranked list of which design parameter to attack next for the biggest improvement. That second output is what working engineers actually need, because no real design ever stops at the first answer.
Accessible for the first time at this level
Until today, multi-physics battery design software was either free academic code with limited capabilities, or enterprise engineering bundles starting at fifteen thousand pounds per year per seat. PBPF-IDO sits at one thousand five hundred pounds per month, runs in any web browser, and delivers usable analysis within five minutes of first sign-in.
