What is home EV charging from a CPO perspective?

Home EV charging for CPOs means deploying AC chargers at private residences while retaining centralised control, monitoring, and commercial ownership. The charger is physically installed at a user’s home, but operationally managed like any other asset in the CPO’s network.

This model is increasingly used for company cars, utilities, housing associations, and subscription-based charging offers.

Why are CPOs expanding into home charging?

CPOs are adding home charging to extend network reach beyond public infrastructure, reduce dependency on peak-time public charging, and increase customer lifetime value.

Home charging also enables predictable usage patterns, lower operational costs per session, and tighter customer relationships compared to purely public networks.

What are the key operational requirements for CPO-managed home charging?

For CPOs, home charging must behave like a networked asset rather than a standalone consumer product. Core requirements typically include:

  • Remote provisioning and configuration

  • Backend connectivity from first power-on

  • Usage metering suitable for billing or reimbursement

  • Fault monitoring and remote diagnostics

  • Controlled access where required (for example, user or vehicle-based)

Without these capabilities, operational overhead increases quickly at scale.

How is load and amperage controlled in home charging deployments?

Amperage is controlled through the CPO’s backend or connected smart charging platform.

The installer or operator sets a maximum current limit for each charger, ensuring charging stays within the electrical capacity of the home and local grid constraints.

This allows CPOs to deploy home charging without site-specific engineering for every installation while still maintaining grid compliance.

What role does OCPP play in home charging for CPOs?

OCPP enables home chargers to communicate with the same backend systems used for public infrastructure.

For CPOs, this means home charging can be monitored, updated, and managed using existing operational tools and processes.

Using OCPP also reduces vendor lock-in and simplifies long-term scaling across mixed charger fleets.

How is billing typically handled for home charging?

Billing models vary depending on the use case, but common approaches include:

  • Monthly reimbursement based on measured consumption

  • Flat-rate home charging subscriptions

  • Cost recovery for fleet or company-car charging

  • Energy-based billing via backend-integrated metering

Accurate energy measurement and reliable connectivity are critical for all models.

Who owns the charger in a CPO home charging model?

Ownership depends on the commercial structure.

In some models, the CPO owns the charger and leases it to the end user. In others, the charger is bundled into a service contract tied to employment, tenancy, or vehicle ownership.

Clear ownership terms reduce churn risk and simplify asset lifecycle management.

What installation challenges should CPOs expect?

Home installations introduce variability compared to public sites. Typical challenges include:

  • Different grid capacities and fuse sizes

  • Varying installation standards across regions

  • Coordination between installer, end user, and operator

Standardised hardware, remote configuration, and clear installer workflows significantly reduce these issues.

How does home charging affect total cost of ownership for CPOs?

When designed correctly, home charging typically delivers lower TCO per charging session than public AC infrastructure.

Lower site costs, minimal civil works, and predictable usage patterns all contribute to improved economics.

However, poor connectivity or lack of remote control can quickly erode these gains through increased support and maintenance costs.
