Load, Energy & Grid Management System for  Commercial EV Charging

HARMON-E is FLEXECHARGE’s cloud platform
for managing the energy side of high-power charging sites.

It gives CPOs one unified platform to connect charging assets, control site load, coordinate BESS-enabled charging environments and prepare high-power charging portfolios for grid flexibility - without replacing the existing CPMS.

Challenges

Challenges that HARMON-E addresses

High-power charging needs a unified load management platform

As high-power charging sites scale, load management can fragment across CPMS logic, charger-level controls, battery systems and site-specific workarounds.

That makes consistent control harder - especially when grid capacity is limited and site demand changes throughout the day.

BESS needs to work with the charging site

Battery Energy Storage Systems can help high-power charging sites boost available power, reduce grid pressure and improve commercial performance.

But batteries only create value when they are coordinated with charging demand, site limits and operational priorities.

Grid requirements are becoming part of charging operations

High-power charging infrastructure is increasingly connected to grid requirements, DSO interfaces and future flexibility opportunities.

Charging demand is dynamic

At HPC sites, charging sessions start, stop and ramp at different times. Demand can change quickly, and static or isolated control logic is often not enough.

Grid capacity is limited

High-power charging sites often need more power than the grid connection can easily provide. Expanding the connection can be expensive, slow or unavailable.

Solutions

The three solutions controlled
via

HARMON-E is the platform used to deploy & control our three solutions: Enable, Optimise and Aggregate.

Enable

Connect and control high-power charging sites through one platform

Enable brings chargers, meters, BESS environments and site infrastructure into HARMON-E.
It creates the foundation for unified load management, site control and grid compliance.

Standard Asset Connect

Connect charging assets, meters and relevant site infrastructure into  HARMON-E.

Dynamic Load Balancing

Distribute available power across chargers and connectors while respecting site limits.

BESS Boost Charging

Coordinate battery power with charging demand to support high-power charging beyond grid constraints.

Grid Control Compliance

Support grid-control requirements through active charger control, reactive site control and DSO-facing capabilities.

Optimise

Improve the commercial performance of high-power charging sites

Optimise improves how energy is used, stored and controlled across the charging site. It helps CPOs reduce cost exposure, increase the value of BESS environments and prepare sites for more advanced energy optimisation.

Peak Shaving

Reduce exposure to peak-related costs by managing charging power against configured site thresholds.

Aggregate

Coordinate flexible charging capacity across multiple sites

Aggregate turns controllable charging sites into a coordinated portfolio. HARMON-E helps CPOs understand, forecast and dispatch flexible capacity across high-power charging locations.

Portfolio Aggregation

Bring multiple charging sites into one coordinated flexibility portfolio.

Customise your load, energy & grid management to ensure that it fits your needs and deploy it to all your sites, with minimal effort.  A new powerful blueprint for scaling your network.

One platform for load, energy and grid management

HARMON-E replaces fragmented control approaches with one platform for managing the energy side of high-power charging. CPOs can manage site load, energy assets and grid constraints through one unified platform layer.

Better use of constrained grid capacity

HARMON-E helps operators get more from the grid capacity already available.By coordinating chargers, connectors, site limits and BESS environments, CPOs can scale high-power charging sites with greater control over how power is allocated.

Built for BESS-enabled HPC sites

HARMON-E is designed for charging sites where batteries are part of the energy strategy.It coordinates BESS behaviour with charging demand, site limits and optimisation logic - helping CPOs use batteries for power boosting, peak reduction and future energy value.

Works with the existing charging stack

HARMON-E is not a CPMS replacement. It works alongside CPMS platforms, chargers, meters, BESS environments and site infrastructure to manage the load, energy and grid layer.

Ready for future flexibility

By connecting and controlling charging assets through HARMON-E, CPOs can prepare sites for aggregation, centralized dispatch and future grid-service opportunities.

Cloud intelligence. Local control where it matters.

HARMON-E is the cloud platform for load, energy and grid management.
FLEXBOX is the local hardware product that extends HARMON-E at sites requiring real-time metering, local control, BESS coordination, deterministic load management or DSO interfacing. 

Together, HARMON-E and FLEXBOX create a cloud + local architecture
for high-power charging sites.

Why combine HARMON-E with the FLEXBOX?

By combining HARMON-E with FLEXBOX, CPOs get the benefits of centralised cloud orchestration together with fast, local site control.

HARMON-E manages the platform logic, feature configuration and portfolio-level visibility, while FLEXBOX enables real-time metering integration, local execution, BESS coordination and stronger DSO-facing capabilities where high-power charging sites require more resilient on-site control.

Explore FLEXBOX

For high-power charging sites that need local control, real-time metering and stronger grid integration, FLEXBOX extends what HARMON-E can do on site.
