EVCare™ is Volterra's AI-driven battery health intelligence platform — delivering real-time diagnostics, predictive failure prevention, and lifecycle optimization for electric vehicle fleets. Purpose-built for transit agencies and commercial fleet operators who can't afford to guess.
The Challenge
Transit agencies are deploying electric fleets at scale — but the tools to manage, protect, and optimize the most expensive asset in those fleets simply don't exist in traditional fleet management software. EVCare™ was built to close that gap.
Battery degradation is invisible until it causes a service disruption — by which point damage is already done to the asset and the schedule.
Operators watch range decrease over time without visibility into why — or which specific cells, packs, or operational patterns are responsible.
Without predictive diagnostics, maintenance teams respond to failures rather than preventing them — driving up labour costs and vehicle downtime.
Batteries represent up to 50% of an EV's total cost. Without health data, agencies can't accurately value, certify, or extend battery lifecycles.
The Architecture
EVCare™ operates through a proprietary three-layer intelligence stack — from individual cell-level sensing through fleet-wide fitness scoring — giving operators an unprecedented view of battery health at every scale.
The foundational sensing layer. CareStar™ monitors individual cell behaviour — voltage, temperature, impedance, and capacity — to detect anomalies at the source before they propagate to pack or system level.
The intelligence synthesis layer. BattHealthScore™ aggregates CareStar data into a single, actionable health index for each vehicle and each pack — replacing subjective technician assessment with objective, AI-derived scoring.
The operational decision layer. FitStar™ translates battery health data into fleet-wide fitness scores, route assignment recommendations, and capital planning insights — connecting the battery room to the boardroom.
The Software Toolkit
EVCare™ deploys as a modular platform — agencies can start with core health monitoring and expand into lifecycle management, maintenance integration, and asset valuation as operations mature.
A real-time system overview of all battery specifications, KPIs, health data, and performance metrics across the entire fleet — the operator's daily starting point.
Summarized actionable insights per vehicle, health influencer breakdowns, and fleet-level projections. Answers the question every operations manager asks: which buses are ready to run today?
Real-time insight into expected battery lifespan and optimal management practices. Helps capital planners forecast replacement cycles with confidence rather than guesswork.
Analyzes, diagnoses, and prescribes maintenance actions — acting as the bridge between EVCare™ health data and existing work order and maintenance management systems.
A prescriptive battery certification system for end-of-service or second-life sale. Ensures maximum residual asset value and supports secondary market confidence.
Tracks health issues against warranty conditions, documents operating and maintenance compliance, and builds the evidence record needed for warranty claim support and approval.
Accurate battery valuation at any stage of life — supporting capital planning, asset sales, insurance, and replacement budgeting with data-backed figures rather than estimates.
Compares manufacturer specifications against real-world fleet performance data, surfacing gaps between nominal and actual battery capability for procurement and vendor management.
Designed for Every Role
EVCare™ was built around a deep understanding of how transit agencies actually operate. Each module delivers role-specific insights — so the right person gets the right data at the right moment.
Executive dashboards with fleet-wide BattHealthScore trends, capital planning forecasts, and ROI impact of battery optimization programs.
Daily FitStar™ readiness scores and route assignment recommendations — deploy every vehicle with confidence in its range and reliability.
AMS™ work prescriptions and priority rankings replace reactive maintenance with a structured, data-driven preventive program.
Cell-level CareStar™ diagnostics and fault codes give technicians the precise information needed to service batteries accurately and efficiently.
TVAL™ and LPM™ outputs support budget modelling, vendor negotiations, and asset lifecycle financial planning with objective battery data.
Fleet electrification performance reporting, battery second-life planning, and energy efficiency metrics that support environmental mandate reporting.
The EVCare™ Vision
Fleet managers gain real-time access to battery health data through EVCare™ dashboards — ending the guesswork in daily vehicle deployment and maintenance scheduling. Peace of mind becomes the baseline, not the aspiration.
Advanced predictive analytics and AI-driven maintenance prescriptions guide fleets toward proactive battery care — reducing total cost of ownership, extending vehicle service life, and improving schedule reliability fleet-wide.
EVCare™ becomes the intelligence backbone of fleet modernization — informing procurement decisions, enabling battery second-life programs, and positioning transit agencies as leaders in sustainable, data-driven public mobility.
