Mobile Charging as a Service (MCaas)

What Is Mobile EV Charging as a Service?

Mobile EV Charging as a Service (MCaaS) is a flexible, on-demand energy delivery model where portable charging units (vans, trailers, or robotic devices) provide EV charging at the vehicle’s location. It combines the logistics of mobile services with the utility of EV charging.

Lack of Fixed Charging Infrastructure

  • Infrastructure build-out is slow and costly: Installing Level 3 chargers involves permitting, construction, utility upgrades, and significant capital.

  • Urban dwellers lack home chargers: Many EV owners in cities park on streets or in multi-unit dwellings with no access to chargers.

  • Grid constraints: Fixed DC fast chargers put heavy loads on the grid, which can trigger delays or require utility intervention.

MCaaS bridges the gap — no need for permits or grid upgrades; it can scale up quickly wherever needed.

    • Last-mile delivery and rideshare fleets need vehicles on the road — not parked at chargers.

    • Downtime is costly: Waiting to charge eats into operational hours.

    • Depot space limitations: Fleet operators may not have room for 10–100 chargers at their site.

    MCaaS provides scheduled, on-location charging (overnight or between shifts) that fits fleet workflows.

    • Stranded EVs or vehicles in areas without chargers need rescue charging.

    • Events, festivals, or temporary sites require EV charging but don’t justify permanent infrastructure.

    • Power outages or natural disasters can knock fixed chargers offline.

    Mobile chargers offer a rapid-deployment backup or temporary solution.

    • Rural or suburban regions are often left behind in charger deployment.

    • Tourism or recreation sites (beaches, parks, ski resorts) may lack year-round demand.

    MCaaS enables EV adoption in these regions before fixed infrastructure is economically viable.

    • Bridge-to-build model: While cities or companies are waiting for permanent chargers to be installed, MCaaS can serve as an interim solution.

    • Test-before-invest: Cities or site owners can trial charging demand with mobile units before building permanent infrastructure.

    Mobile service derisks investment and supports smoother EV rollout.

Mobile Charging Hardware

Battery-integrated systems (86kWh/90kW): Pre-charged mobile battery packs brought to vehicles.

    • Customer app for scheduling, tracking, and payment.

    • Operator dashboard for route optimization, fleet management.

    • Integration with EV telematics for proactive charging needs.

    • On-demand: User requests charge via app.

    • Scheduled: Regular fleet or B2B charging windows.

    • Emergency: Roadside assistance or low-battery response.

    • Fleet Operators (logistics, rental cars, rideshare, etc.)

    • Urban EV owners with no home chargers.

    • Corporate campuses or events.

    • Government/military and municipal vehicles.

    • Remote/off-grid areas or during power outages.

  • Per Charge Pricing : Flat fee + kWh fee (e.g., $25 callout + $0.45/kWh)

    Subscription : For regular fleet charging: monthly fee per vehicle.

    B2B Contracting : White-label or managed charging services for businesses.
