Membership charging plans are subscription-based pricing models offered by a charge point operator (CPO) or e-mobility service provider (eMSP) that give EV drivers or fleets access to charging services under predefined terms—typically combining a recurring fee with discounted energy rates, session fees, roaming benefits, or bundled charging allowances.
What Are Membership Charging Plans?
A membership charging plan is a commercial agreement where a user pays a monthly or annual fee in exchange for charging benefits. These plans are used to:
– Reduce the per-kWh price compared to pay-as-you-go tariffs
– Simplify billing through a single account and invoice
– Offer access to a wider network via roaming
– Provide predictable costs for frequent users, fleets, or employees
Membership plans may be consumer-focused or designed for business and fleet accounts.
Why Membership Charging Plans Matter in EV Charging
For charging operators and site owners, membership plans can:
– Increase customer retention and repeat usage
– Improve revenue predictability and utilization
– Encourage drivers to choose a specific network over competitors
– Support business models for workplace, residential, and fleet charging ecosystems
For drivers and fleets, they can lower costs and reduce friction at the point of charging.
Common Types of Membership Charging Plans
Unlimited or bundled plans
– Fixed fee that includes a defined amount of charging (kWh or sessions)
– May include fair-use rules or power/time restrictions
Discount plans
– Membership fee + reduced per-kWh rate or reduced session fee
– Often best for high-frequency users
Roaming-inclusive plans
– One contract provides access across multiple networks via roaming agreements
– Can include different rates for “home network” vs roaming sessions
Fleet and business accounts
– Central billing, driver management, cost allocation, and reporting
– May include depot + public charging access in one plan
Workplace employee plans
– Reduced rates or payroll-linked billing for employees charging at company sites
Typical Pricing Components
Membership charging plans often combine:
– Recurring subscription fee (monthly/annual)
– Energy price (€/kWh)
– Session fee (start fee) and/or time fee (idle/parking fee)
– Network access fees for roaming sessions
– Discounts by location, time of day, or user group
The final cost depends on charging behavior, location, and tariff structure.
How Membership Plans Work Operationally
– User signs up in an app or via fleet onboarding
– Authentication is provided via RFID card, app, or Plug & Charge (where supported)
– Charging sessions are tracked in the CPMS and billed according to the plan rules
– Users receive invoices/receipts and usage history
– Fleets can allocate costs by driver, vehicle, or cost center
Benefits and Limitations
Benefits
– Lower cost per kWh for frequent charging
– Predictable billing and simplified access
– Potential network-wide access through roaming
– Useful for fleets needing centralized reporting
Limitations
– Not cost-effective for low-usage drivers
– Roaming rates may still be higher than home-network rates
– Plans may include fair-use limits or exclude certain high-power chargers
– Complexity in comparing plans due to mixed fees (kWh + time + session)
Considerations for CPOs and Site Owners
– Align membership tiers with utilization goals and capacity constraints
– Use managed charging and pricing signals to reduce peak demand
– Ensure clear tariff communication to avoid billing disputes
– Combine membership with loyalty programs, corporate accounts, and roaming partnerships
– Monitor profitability: heavy users can increase energy cost exposure if pricing is misaligned with wholesale volatility
