A Deep Dive into Energy Management using EO Hub

What is EO’s Energy Management solution? ​​

Energy Management System​ for Electric fleets 

EO Hub is an energy management system which automates load management, distributing energy intelligently and safely throughout your depot, it also enables fleet operators to utilise off-peak energy tariffs. ​

EO Hub is an OCPP[1] (Open Charge Point Protocol) load-balancing device that allows any site with restricted power access to efficiently distribute the available power to all active charging stations. ​

EO Hub is powered by the EO Cloud, enabling you to:

  • view live power consumption at your depot​

  • configure charging profiles to reduce peak energy costs​

  • schedule charging to make the most of off-peak and renewable energy

  • ensure the fleet is fully charged and ready to complete its next shift

EO’s energy management solution gives you full control of your power usage at all times!​

01. What is EO Hub?​

EO Hub is an energy management system which automates load management and enables fleet operators to utilise and schedule charging sessions during off-peak energy tariffs. ​

EO Hub is an OCPP load-controlling device that allows sites with restricted power access to distribute the available power efficiently to all active charging stations. It is the perfect partner to the EO Cloud, enabling you to automatically calculate the available power on-site and distribute it to your connected vehicles, giving you complete control of your power usage at all times. ​

​If, for any reason, EO Hub detects that the energy consumption from the charging stations is approaching the limit of your incoming supply, it immediately adjusts the load to your charging vehicles to prevent overloading your main supply.​

If the connection between EO Hub and the EO Cloud is lost, EO Hub will continue to seamlessly manage the load offline. In this scenario, all messages received from the charging station will be stored temporarily in EO Hub until the connection is re-established.


02. How can EO Hub help your fleet?

One of the biggest challenges fleets face when moving to EVs is being able to manage the available power on-site. Many depots do not have the power infrastructure to support large electric fleets, and securing the required power from the grid is expensive and takes time.

Therefore, fleets require a reliable load management solution on-site to ensure that its EVs will receive the necessary amount of charge without breaching the site's power constraints. ​

Now, how do we possibly resolve such issues? ​

Our Research & Development team has been working extremely hard to develop EO Hub to solve one fundamental problem: to enable electric fleets to operate beyond the limits of their electrical systems. EO Hub enables live monitoring of power coming into their site and intelligently distributing it to the vehicles that need it most, making sure fleets are always up and running when needed.

03. What benefits can you see from implementing EO Hub to your depot?

EO Hub provides a various number of features and solutions and operates as the "brain of the depot": ​

  • Monitor live power of your entire site: EO Hub monitors the power coming into your site, instantly calculates and distributes available power to the vehicles that need it the most. EO Hub also provides the ability to integrate other on-site energy systems​, such as solar power

  • Scale your fleet with peace of mind: EO Hub scales itself based on your depot size and capacity so you can continue to grow your EV fleet. You can connect a virtually unlimited number of OCPP devices to the EO Hub​

  • Full flexibility: Gives you the ability to control any OCPP charger – AC, DC, EO, 3rd party, you name it. Our products are all open source, giving you the choice to select your hardware​

  • Simplicity right at your fingertips: Synchronises both power and performance data directly onto the EO Cloud portal​

  • Goodbye connectivity issues: You can actively regulate available power offline (without an internet connection) ​

  • Forget about upgrading your grid connection: EO Hub optimises the available power on-site, reducing or removing the need for a costly grid upgrade.

  • Secure and scalable by design: ability to integrate with other energy and management systems  ​

  • Do all of this remotely: configure sites remotely from the cloud-based management system, EO Cloud 

04. How do I go about implementing EO Hub for my business?

EO Hub requires two key components: ​

1. An active EO Cloud subscription
2. OCPP 1.6 compatible charging stations ​

Once the charging stations are installed and the site is connected to EO Cloud, installing EO Hub is simple. EO’s trained technicians will take care of all the heavy lifting. We’ll come to your site to install EO Hub at your main incoming supply, along with the networking equipment that enables it to communicate with all connected charging devices offline (if not already in place). We’ll connect EO Hub to your smart meter (or provide one if needed), and install our EO Router Pack to enable it to independently communicate with our EO Cloud back office.​

The final step involves configuring all of the connected charging devices so they communicate directly with EO Hub. EO Hub will pass these messages on to the EO Cloud when connected to enable you to monitor and manage the system remotely.​

In the event that the connection between the site and the EO Cloud is lost, EO Hub will take over and continue to manage your power and all connected charging stations. ​

05. Automatic vs. Static Load Management

The introduction of EO Hub offers the opportunity to introduce Automatic Load Management to your depot. 

EO Cloud offers Static Load Management by default, while Automatic requires a Smart Meter installed on-site and connected to EO Hub. ​

Static Load Management[2] -  users can configure and set automatic thresholds (in Amps), which EO Hub will ensure are not exceeded. ​

​Automatic Load Management works via the connection of a smart meter.  

However, the main difference is how the power available to the charging stations is calculated. EO Hub considers the overall site limit and the energy consumption values from the smart meter. Allowing the remaining power to be distributed evenly amongst all active charging stations. In cases where the depot is under a larger load, less power will be available to the charging stations. This works vice-versa in less busy periods, meaning more power will be available to them.


06. Do I need to increase my power capacity with EO Hub?

No, EO Hub reduces and in some cases removes the need for increasing power capacity by utilising the available power on-site whilst smartly distributing across your fleet!

  • No more lengthy application processes

  • No more grid upgrade fees

  • No additional electrical infrastructure​

One small device that gives you complete power autonomy over your depots!


OCPP [1]: The Open Charge Point Protocol (OCPP) is an open-source communication standard for Electric Vehicle (EV) charging stations and network software firms. This means that any EV charging station adhering to OCPP can be set up to operate with any OCPP-compliant software. ​

Static Load Management [2]: Monitors the energy consumption from all charging stations on-site, and the moment it detects that the sum of all the energy consumed is getting close to the site limit, it works to recalculate a new 'safe level' of consumption, which is then sent to all active charging stations. Allowing each active charging station to receive an equal amount of power. For example, if the total limit on-site is set at 1000 Amps, with 10 x DC charging stations, each with a maximum output of 200 A, and all the chargers are actively dispensing power, EO Hub will reduce their output to 100 A each, down from 200 A. In the case that one of the charging stations no longer actively charges a vehicle, then the remaining nine charging stations would split the extra 100 A, or each would get approx. 110A.
