EV charging load management
Make better use of your site’s available electrical capacity
Charging EVolution designs and installs intelligent EV charging load management systems for strata communities, workplaces, fleets and commercial properties across Victoria.
Load management protects your electrical infrastructure, adjusts charging to suit building demand and may reduce or avoid the need for costly supply upgrades.
How much EV charging can your site support?
EV chargers can place significant additional demand on a property’s electrical supply, particularly when several vehicles charge simultaneously.
The amount of charging your site can support depends on its electrical supply, existing building demand, parking durations, vehicle requirements and plans for future expansion. Simply connecting every charger at its maximum output may overload the electrical infrastructure or lead to unnecessary upgrade costs.
A properly designed load management system controls charging demand so that available power can be distributed safely and effectively.
What is EV charging load management?
EV charging load management controls the total amount of power allocated to a charging installation and distributes it across the connected vehicles.
When electrical capacity is limited, charger output can be reduced or temporarily paused. As more power becomes available, charging output can increase automatically.
Load management does not increase your site’s electrical capacity. It allows the available capacity to be used more effectively while helping protect the building’s electrical supply.
Static and dynamic load management
Static load management
Static load management establishes a fixed amount of electrical capacity for the charging system. The connected chargers share this allocation without exceeding the predetermined limit.
This may be suitable where sufficient electrical capacity can be permanently dedicated to EV charging.
Dynamic load management
Dynamic load management uses a power meter to monitor the property’s electricity demand in real time.
When building demand increases, the power available to the chargers is reduced. When building demand falls, additional power can be made available for vehicle charging.
This is particularly useful for properties with variable electrical demand or limited spare capacity.
We assess each property individually to determine whether static or dynamic load management—or a combination of both—is appropriate.
EcoStruxure EV charging expert
Charging EVolution supplies and installs Schneider Electric’s EcoStruxure EV Charging Expert, an intelligent controller designed specifically for EV charging infrastructure.
The system can manage how available power is distributed between chargers, electrical zones and connected vehicles. Charging priorities can also be assigned to selected users or vehicles, such as fleet vehicles, emergency vehicles or essential staff.
Key capabilities include:
- Static and dynamic load management
- Real-time monitoring of site demand
- Multiple charging zones and priority rules
- Remote monitoring, diagnostics and reporting
- User access and charging-session management
- Integration with compatible Charge Point Operators and OCPP systems
EcoStruxure EV Charging Expert can support smaller installations as well as larger, multi-zone charging networks, allowing the system to grow with your requirements.
Benefits of EV charging load management
A properly designed system can:
- Help protect the property’s electrical infrastructure
- Reduce the risk of overloading or nuisance tripping
- Make better use of existing electrical capacity
- Reduce or avoid costly supply upgrades
- Allocate power fairly between connected vehicles
- Prioritise selected users or fleet vehicles
- Support the staged expansion of charging infrastructure
- Provide greater visibility over charging activity and energy use
The objective is not to install as many chargers as possible. It is to provide a charging solution that suits how your property will actually use them.
Where is load management used?
Strata and apartment buildings
Power can be shared between residents while protecting the building’s common electrical supply. The system can also support staged expansion as more residents purchase electric vehicles.
Workplaces and commercial properties
Charging demand can be managed alongside lighting, air conditioning, machinery and other building loads without unnecessarily increasing the property’s maximum demand.
Fleet depots
Available power can be distributed across fleet vehicles, with priority given to vehicles that must be ready for specific operational requirements.
Hospitality and destination venues
Hotels, wineries, accommodation providers and other destinations can offer EV charging while managing demand alongside their existing business operations.
Commercial and public car parks
Multiple AC and DC chargers can be coordinated across different electrical zones, with centralised monitoring and access control.
Our approach to load management
01.
Understanding your requirements
We begin by taking the time to understand how charging will be used at your property, including vehicle types, parking durations, access requirements, charging priorities and plans for future expansion. Your budget is considered from the outset.
02.
Assessing the site
We conduct a detailed assessment of the property’s electrical supply, switchboards, existing demand, cable routes, communications infrastructure and operational constraints.
Where required, we can undertake electrical data logging to establish an accurate picture of the site’s available capacity and demand profile.
03.
Designing the system
Based on our findings, we recommend the appropriate charging equipment, electrical infrastructure and load management strategy.
Our proposal clearly outlines the recommended solution, associated electrical works and project costs.
04.
Installation and commissioning
Our in-house electrical team manages the installation and commissioning from start to finish. We are experienced in working in live environments and plan our work carefully to minimise disruption.
The completed system is tested, configured and commissioned to meet the project requirements and applicable Australian Standards.
05.
Handover and ongoing support
We provide system handover, user guidance and ongoing after-sales support. You will have a single point of contact throughout the project and for ongoing after-sales support.
Frequently asked questions
No. If sufficient electrical capacity can be permanently allocated to the chargers, a dedicated supply or basic static control may be sufficient. We determine this during the site assessment.
In some cases, yes. Dynamic load management may allow EV charging to operate within the property’s existing supply capacity. However, this depends on the site’s electrical infrastructure and charging requirements and cannot be guaranteed without an assessment.
Charging output may be temporarily reduced when building demand is high or several vehicles are charging simultaneously. The system increases charging output when more capacity becomes available.
We consider parking duration and vehicle requirements when designing the system so that charging performance remains practical for users.
Yes. Charging priorities can be configured for selected users or vehicles, making this useful for fleets, essential staff and other operational requirements.
Yes, provided future expansion is considered during the initial design. Switchboard capacity, submains, communications cabling, conduits and load management licensing should all be considered at the outset.
