(01) The problem

Recognise this?

01

The DSO can't expand your connection, or only in 18 months. And your fleet, depot or network is growing now.

02

You pay for electricity at the wrong moments. Everyone plugs in at 18:00 while cars only leave at 06:00. You pay the maximum.

03

CSRD reporting demands audit-grade emissions data. Your current tool doesn't export a CSV your accountant accepts.

(02) What it does

Concretely, in four points

01

Dynamic load balancing on EPEX spot prices, OpenADR DSO signals, and per-user priorities (departure time, energy need, preferred profile).

02

Two strategies per cluster: proportional reduction or priority-based rotation, with configurable minimum-current thresholds (default 6A).

03

Demand-response participation via OpenADR for signals from Liander, Stedin and Enexis.

04

Audit-grade emissions and cost reporting: exportable for CSRD and other compliance.

(03) For whom

Smart Charging is the differentiator for fleet operators, private CPOs under grid pressure, and public CPOs running EPEX arbitrage.

(04) Proof

EPEX price optimisation and OpenADR integration are live in production. Proven 20–40% savings on charging cost for fleets with well-defined departure times. NRG energy expertise via the Evinity joint venture brings direct DSO relations with the Dutch grid operators.

(05) FAQ

The question we hear every week

Does this also work with my existing CPMS, or do I have to switch?

Smart Charging works deepest with ihomer Charge Management, but via ihomer Gateway we can also push charging profiles into your existing CPMS. We figure out what fits your setup in a first call.
