Know your battery.
Plan its life.
Personalised EV battery-life and charging-strategy intelligence based on your exact vehicle, charging habits, climate and ownership plans.
Your battery. Your habits. Your forecast.
Why 80% isn't the whole story
Generic advice judges charging by the maximum SOC. Battery ageing depends on how long the battery stays at high SOC, how warm it is, how deep and how fast you cycle it — and how long you plan to own the car.
- 1Reaching 100% shortly before you drive adds little time at high SOC.
- 2Parking for days at very high SOC in the heat is what accumulates stress.
- 3A stricter strategy can cost dozens of extra charging sessions for a small benefit.
How Voltgevity works
- 01
Pick your exact vehicle — battery chemistry, capacity, buffers and charging curve, each with a confidence level.
- 02
Describe how you really drive and charge: routines, departure times, fast-charging habits, climate.
- 03
Thousands of Monte Carlo simulations project your battery with P10/P50/P90 bands.
- 04
Compare strategies and see whether changing is worth it for your ownership period.
Your habits matter
Model multiple recurring charging routines — nightly home charging, workplace charging, motorway fast-charging stops — each with arrival and target SOC ranges, charger power and how long the car waits before you leave.
Time at SOC matters
Voltgevity tracks every hour of the year by state of charge and estimated pack temperature. A battery that reaches 100% and departs is treated very differently from one parked at 100% for days.
Chemistry matters
LFP, NMC, NCA, LMFP and sodium-ion age differently. Each has its own model and evidence — LFP never borrows NMC coefficients — and uncertain chemistry widens the prediction bands instead of being guessed.
Compare charging strategies
Strategy Lab compares your actual behaviour with the 80% advice, a battery-preservation strategy and a maximum-convenience strategy using paired simulations.
See whether changing behaviour is worth it
Every comparison weighs projected capacity retention against extra charging sessions, hours connected, cost and estimated residual value — for your ownership horizon and priorities.
Transparent science
Every coefficient carries provenance and a probability distribution. Every result shows model versions, evidence, assumptions and confidence — and can be reproduced exactly.
Example simulation
A 100 kWh-class NMC performance EV driven 55,000 km per year, charged to 100% at home with prompt departures and frequent motorway fast charging.

Frequently asked questions
Is charging to 100% bad for my battery?
Not in itself. What matters is how long the battery stays at very high SOC and how warm it is. Charging to 100% shortly before a trip adds little calendar stress; leaving it at 100% for days, especially in heat, adds more.
Does Voltgevity measure my battery?
No. Voltgevity provides scientifically informed estimates. It does not physically inspect cells. You can log real SOH measurements to personalise the model.
Why do you show a range instead of one number?
Battery packs vary and the science has uncertainty. P50 is the median projection, not a guarantee; P10–P90 shows where 80% of simulated outcomes fall.
Will Voltgevity always tell me to charge to 80%?
No. If a stricter strategy brings little benefit during your ownership period and costs convenience, Voltgevity will tell you your current strategy is already suitable.
