- Smart charging uses software to control when and how electricity flows to chargers, cutting costs and protecting grid capacity without affecting driver experience.
- The biggest levers are dynamic load management, scheduled off-peak charging, and peak demand shaving.
- Operators who implement smart energy management typically reduce energy costs, avoid costly grid upgrades, and open the door to grid service revenue.
- Spirii Connect delivers all of these capabilities as standard platform features, not optional extras.
Energy is the largest variable cost in running a charging network. The operators who manage it intelligently have a structural cost advantage over those who don't. This article covers the practical tools available and how to use them. For a definition of the underlying concept, see our smart energy management glossary entry.
The problem with dumb charging
A charging network without smart energy management draws power on demand. When multiple vehicles plug in simultaneously, the site draws at full capacity. If that exceeds the available grid connection, circuit breakers trip, drivers are left without a charge, and the operator faces an expensive grid upgrade.
Even without an outage, unmanaged charging concentrates demand in peak hours when electricity is most expensive. That means operators pay peak rates for every session, regardless of whether the vehicle actually needed to charge urgently.
Dynamic load management: the foundation
Dynamic Load Management (DLM) is the core tool. It monitors the total power draw across all active chargers in real time and distributes available capacity automatically. If ten vehicles plug in simultaneously at a site rated for 100 kW, DLM gives each charger 10 kW rather than letting the first few take full power and tripping the circuit.
The practical benefit for operators is significant. DLM allows more chargers to be installed on an existing grid connection, deferring or avoiding costly infrastructure upgrades. A site that might have needed a grid upgrade to support ten chargers can often run twenty with DLM in place.
Scheduled charging: moving demand to cheaper hours
Not every vehicle needs to charge immediately. Fleet vehicles charging overnight at a depot, or workplace chargers used during office hours, have a window of several hours to complete a charge. Scheduled charging takes advantage of that window by shifting sessions to off-peak periods when electricity is cheapest.
For fleet operators, this can mean the difference between paying peak commercial rates and off-peak rates for the same energy. Over a fleet of fifty vehicles, that difference compounds quickly into meaningful cost savings month over month.
Peak shaving: controlling demand charges
Many commercial electricity tariffs include demand charges based on peak consumption within a billing period. A single 15-minute spike can set the demand charge for the entire month. Peak shaving caps total site consumption at a preset limit, smoothing out those spikes and reducing the demand charge component of the bill.
Combined with scheduled charging, peak shaving gives operators full control over their energy cost profile without restricting charger availability for drivers who need it.
Grid services: turning cost into revenue
The most advanced application of smart energy management is grid services. By making charging assets responsive to grid signals, operators can participate in balancing programmes that pay for controllable load. In effect, the charging network becomes a grid asset rather than just a grid draw.
This is still emerging in most markets but is increasingly commercially viable, particularly for larger depot and public charging operators with predictable load profiles.
How Spirii Connect delivers these capabilities
All of the above are core features in Spirii Connect, not optional modules. Dynamic Load Management, scheduling, peak shaving controls, and grid services integration are available to every operator on the platform. The Insights Dashboard tracks energy consumption, session costs, and efficiency across all sites, giving operators the data they need to optimise continuously.
