SOHpro
Your electric's passport — the historical battery-health record powered by scans from any partner shop.
FREE BATTERY HEALTH SIMULATOR
Project your EV battery's health over 15 years
Same physics engine as a real SOHpro Score, fed by the inputs you choose: chemistry, climate, usage. The shaded band is the P10–P90 confidence interval from a 200-sample Monte Carlo. This is an estimate — the only way to know your battery's real SOH is to scan it.
Engine: NREL Smith (calendar) + Sandia/Preger 2020 (cycle). Methodology: report-technical-guide §14.
Your vehicle
Not sure? If the car lives on the coast or in the lowlands, pick Tropical; a highland city is Temperate.
Nissan Leaf (40 kWh) (2018+)
Estimate what percentage of your total energy is charged at fast public stations (DC, >50 kW) versus slow at home. For reference: 0 % if you always plug in at home, 20 % if you only use fast charging on occasional trips, 50 % if you mix home and public, 80 % if you rely mostly on public fast chargers.

Expected SOH in 2031
Likely range: 88–91 %
Expected SOH over 15 years
Solid line is the P50 (median). Shaded band is P10–P90 — 80 % of plausible trajectories given the inputs.
| Year | Odometer | Expected SOH | Likely range |
|---|---|---|---|
| 2027 | 55,000 km | 94.0% | 93–95 % |
| 2029 | 85,000 km | 91.6% | 90–93 % |
| 2031 | 115,000 km | 89.4% | 88–91 % |
| 2034 | 160,000 km | 86.2% | 84–89 % |
| 2036 | 190,000 km | 84.1% | 81–87 % |
| 2041 | 265,000 km | 79.2% | 75–83 % |

Your inputs are encoded in the URL — anyone who opens the link sees the same projection. Useful for showing your dealer, a buyer, or a friend who's evaluating the same model.
Want the real number?
This simulator shows what the math says. Upload an OBD scan or PDF report from your vehicle, and we compute your actual SOHpro Score against the same physics — co-signed by a partner shop, locked to your VIN, and travels with the car at resale.

How Much Battery Will You Lose in 8 Years? What an EV Owner Can Actually Expect
The question every EV owner asks sooner or later: how much range am I going to lose over the years? The honest answer comes down to three things — and in Latin America, one of them is simply where you live.

Why does one person swear charging to 100% is fine and another says it kills the battery?
Your neighbor swears he charges to 100% every day with zero problems. The forum says that's exactly how you murder a battery. They can both be right—it comes down to the chemistry inside your EV.

How Your EV Battery Really Ages (and How Long It Will Last)
The fear says you'll be swapping the battery in a few years. Reality is almost the opposite: it dips a little early on, settles, and outlives the car itself. Here's how degradation actually plays out, year by year.
This is a projection from physics-grounded models, not a measurement of your specific battery. Real packs vary; manufacturing tolerance, usage patterns, and unobserved factors can shift the result by ±5 %.
The model is currently calibrated against published research (NREL, Sandia, Geotab). LATAM-specific calibration from our own scan data lands when N ≥ 100 multi-visit VINs accumulate.
