EV load management  relates to the effective distribution and control of electrical loads associated with charging.

EV load management is the ability to control how much energy an EV charger dispenses to a vehicle; controlling when electricity is used, where it goes and how much goes to each vehicle. Load management ensures that each vehicle is charged as much as possible, without threatening the electricity grid, building infrastructure or risking high demand charges, by specifically addressing the even distribution of electrical loads within the power distribution system to maintain stability and prevent issues related to imbalances.

Load Management Methods

Static Load Management

Static load management involves the installation of EV charging equipment on a dedicated power supply that has a known fixed power capacity. The EV chargers are designed to effectively manage this power supply by evenly distributing the load between them as more sockets are utilised. This can be done at Cloud level (using back-office software) or locally to the chargers using the Ratio Sense.

For example, a site that has 22kW available in total and 4 sockets; each charge point will receive the maximum power available i.e. 5.5kW for 4 vehicles, 7.3kW for three vehicles, 11kW for two vehicles.

Dynamic Load Management

Dynamic load management monitors the building’s energy supply and usage, calculating the power available and distributing it equally to the EV charger installation.

As the building power consumption increases (heavy machinery being switched on or off for example), the additional dynamic load management hardware will increase or decrease the power available to the EV charger installation.

Ratio ticked all these boxes and more

At Garage Play we turn tired and run-down garages into a genuine new space for the home, this could be a gym, an office, or simply a neater, nicer garage space. As part of our offering we wanted to supply EV charging equipment, but we need it to be smart enough to cope with differing power availability and solar interoperability, reliable and robust enough to cope with everyday living, plus good looking to fit in with our total proposition. Ratio ticked all these boxes and more!

One happy customer! 

Matt and the team at Ratio helped us out recently when we needed an urgent installation for a solar compatible home installation. They delivered the unit directly to site the next day and Martin even came out to site to make sure everything went well. One happy customer!
