Industry Problem Statement
Battery degradation is the largest hidden cost driver in India's 2W and 3W EV segment. OEMs, fleets, and owners routinely discover capacity loss only after range collapse, warranty disputes, or unexpected replacement CAPEX.
Traditional approaches rely on coarse SOC displays, ad-hoc load tests, or post-failure teardown. These methods cannot model how daily distance, fast charging, depth-of-discharge habits, ambient temperature, and load patterns compound stress over years.
Business impact: elevated warranty claims, fleet downtime, stranded assets, and eroded customer trust. Financial impact: premature pack replacement (often ₹25,000–₹80,000+ per 2W/3W asset). Safety impact: stressed packs increase thermal and swelling risk when operated beyond safe envelopes. Regulatory impact: traceability and responsible battery lifecycle management under evolving AIS and recycling norms.
EVXpertz Solution Overview
The EVXpertz Battery Degradation Predictor combines physics-informed degradation curves with India-calibrated usage multipliers. Inputs include chemistry (LFP/NMC), pack kWh, daily km, load, terrain, charging type, charging habits, frequency, and average ambient temperature.
The engine projects annual degradation %, remaining useful life, equivalent full cycles, Battery Care Score (0–100), and side-by-side current vs optimized scenarios (e.g. 20–80% SOC + slower charging). Outputs include a downloadable PDF report with health-over-time charting.
Methodology layers calendar aging, cycle stress, temperature exposure, and fast-charge penalties — aligned with field learnings from EVXpertz service networks serving multi-brand 2W/3W fleets.

Frequently Asked Questions
What data inputs are required?
Vehicle model or custom kWh, chemistry, daily km, load, terrain, charging type, habits, frequency, and average temperature. No telematics mandatory for the public tool.
How accurate are projections?
Outputs are model-based estimates calibrated for Indian 2W/3W conditions — not a substitute for laboratory SOH testing. Accuracy improves when paired with BMS telematics in enterprise deployments.
Can OEMs integrate via API?
Yes — EVXpertz supports API and batch scoring for fleets, dealers, and finance partners. Contact us for integration architecture.
Is rider data private?
The free web tool processes inputs client-side where possible; enterprise deployments support tenant isolation and DPDP-aligned data handling.
Does it support LFP and NMC?
Yes — chemistry-specific degradation curves are applied.
How should fleets interpret Care Score?
Scores below 60 indicate elevated stress; prioritize coaching, charging infrastructure, or inspection for units below 50.
Can this support used EV marketplaces?
Yes — degradation forecasts and care scores provide buyer/seller transparency for pricing and disclosure.
What fleet sizes are supported?
From single vehicles to thousands via partner API and batch reports.
How does this relate to AIS-156?
Supports safety and lifecycle documentation aligned with responsible battery management; not a certification substitute.
Can insurers use outputs for underwriting?
Risk tiers and stress scores inform premium and coverage decisions when integrated with claims history.
What charging infrastructure is assumed?
Slow (home/depot) vs fast (public/DC) profiles with habit modifiers — compatible with mixed infrastructure fleets.
How often should reports be regenerated?
Quarterly for fleets; after material habit, route, or climate changes; before warranty or resale events.
