EVCare™ by Volterra is the world's most comprehensive AI-driven battery health platform for electric vehicle fleets. Purpose-built for transit agencies and enterprise fleet operators who can't afford to guess about their most valuable asset.
The Problem
Transit agencies and fleet operators across North America are adding electric buses and commercial vehicles at pace. But the tools to monitor, manage, and protect the batteries powering those fleets simply don't exist in traditional fleet management software.
Batteries represent up to 50% of an electric vehicle's total purchase cost — yet most fleets operate with zero visibility into battery health, degradation trajectory, or remaining useful life.
No early warning system
Battery degradation is invisible until it causes a service disruption. By then, damage to the asset — and the schedule — is already done.
Shrinking range, no explanation
Operators watch range decrease over time with no visibility into which cells, packs, or operational patterns are responsible — or what to do about it.
Reactive maintenance is expensive
Without predictive diagnostics, maintenance teams respond to failures rather than preventing them — driving up labour costs, parts costs, and unplanned downtime.
Asset value erodes invisibly
Without health records, agencies can't accurately value, insure, certify, or plan replacement for the most expensive component in their fleet.
Battery expertise is scarce
Electrochemical diagnostics require specialist knowledge most transit agencies simply don't have in-house — and can't easily hire for.
The EVCare™ Platform
EVCare™ operates through a proprietary three-layer intelligence stack — from individual cell-level sensing through fleet-wide fitness scoring — giving operators complete battery visibility at every scale.
The foundational sensing layer. Monitors individual cell behaviour — voltage, temperature, impedance, and capacity — detecting anomalies at the source before they escalate to pack or system level failure.
Aggregates CareStar™ data into a single, AI-derived health index per vehicle and pack — replacing subjective technician assessment with objective, continuously updated battery intelligence.
Translates battery health data into fleet-wide fitness scores, route assignment recommendations, and capital planning insights. Connects the battery room to the boardroom.
How It Works
EVCare™ connects to your existing vehicle telematics and BMS data streams — no proprietary hardware required. Data flows continuously from every vehicle in your fleet.
CareStar™ processes cell-level data in real time. BattHealthScore™ synthesizes signals into an objective health index for every vehicle, updated continuously throughout the operating day.
FitStar™ ranks your fleet by readiness and generates specific maintenance prescriptions through AMS™ — telling your team exactly which vehicles need attention, and what to do.
LPM™ and TVAL™ translate health data into lifecycle and financial planning outputs — enabling confident capital decisions, warranty management, and second-life battery planning.
Who It's For
EVCare™ was designed around how transit agencies actually work — delivering role-specific intelligence so the right person gets the right data at exactly the right moment.
Fleet-wide BattHealthScore™ trends, capital planning forecasts, and ROI impact of battery optimization programs — for confident board-level reporting.
Daily vehicle readiness scores and route assignment recommendations. Deploy every bus with confidence in its range and reliability before the first trip of the day.
AMS™ work prescriptions and priority rankings replace reactive maintenance with a structured, data-driven preventive program — and documented warranty evidence.
Cell-level CareStar™ diagnostics and specific fault codes give technicians the precise information needed to service batteries accurately and efficiently — no guesswork.
TVAL™ and LPM™ outputs support budget modelling, vendor negotiations, and asset lifecycle financial planning with objective, data-backed valuations.
Fleet electrification performance reporting, battery second-life planning, and energy efficiency metrics supporting environmental mandate reporting and ESG accountability.
The Market
The EV fleet management market is growing at 22.7% annually — driven by government mandates, $5B+ in federal fleet funding, and the mass deployment of electric buses and commercial vehicles across North America. Volterra sits at the highest-value layer of that market: the battery intelligence that makes electric fleets actually work.
