Private charging is EV charging intended for a restricted group of users rather than the general public. Access is controlled by the site owner or operator—typically for employees, residents, fleet vehicles, or authorized visitors. Private charging can take place at homes, workplaces, depots, gated residential sites, and private parking facilities.
Private charging may still use networked chargers and a CPMS, but the access and commercial rules are defined by the private site.
Why Private Charging Matters in EV Infrastructure
Private charging is a core part of EV adoption because most charging happens when vehicles are parked for long periods. It helps organizations and property owners:
– Ensure predictable charging access for known users (no public queues)
– Reduce operating costs through controlled tariffs and off-peak scheduling
– Support fleet readiness and operational planning
– Enable billing and cost allocation for residents/tenants/employees
– Improve property value and tenant satisfaction with reliable EV-ready amenities
– Reduce reliance on public charging for daily energy needs
How Private Charging Works
Private charging typically includes:
– Chargers installed on private land (homes, workplaces, depots, residential car parks)
– Access control (RFID cards, app accounts, Plug & Charge, or whitelists)
– Optional billing rules (free charging, internal chargeback, or resident billing)
– Load controls to fit within site constraints (load management, phase balancing)
– Reporting for energy use, cost allocation, and CO₂ accounting (where required)
Common Private Charging Models
– Home charging: single user, typically simple access and basic scheduling
– Workplace charging: employee access with optional payroll/department allocation
– Residential multi-tenant charging: tenants/residents billed individually, often via MID metering
– Fleet depot charging: controlled access and scheduling aligned to dispatch deadlines
– Hospitality guest charging: private or semi-private access for guests (sometimes time-limited)
Key Design Considerations
– Electrical capacity planning (import capacity, maximum site demand limit)
– Load management and phase balancing for sites with many AC chargers
– User identification and permissions (who can charge, when, and at what price)
– Billing and compliance (kWh-based billing may require MID metering)
– Bay discipline and policies (reserved bays, overstay management)
– Cybersecurity and privacy controls for user data (privacy-by-design)
Benefits
– High convenience and predictable access for approved users
– Lower cost per kWh vs many public tariffs (site- and tariff-dependent)
– Easier to implement scheduled charging to maximize off-peak energy
– Better operational control and reporting for organizations
– Scalable for phased deployment (start small, expand as EV adoption grows)
Limitations and Practical Considerations
– Upfront CAPEX and building electrical upgrades may be required
– Multi-tenant billing and metering can add complexity
– Shared private sites still need enforcement to prevent bay blocking
– Requires ongoing administration (user accounts, access cards, billing disputes)
– Limited usefulness for the general public unless the site later becomes semi-public or public
