Importance of EV Charger Load Management

What is Load Management and Why is it an important feature of EV Charging in Commercial, Workplace or Apartments

Electric Vehicles (EVs) will be the future of transport all over the world. However, questions about these loads have been rising in recent years, especially regarding the power needed to charge these vehicles and the demand that these will place on the Australian electrical grid.

Power capacity needed for an EV charging system is the biggest obstacle preventing the development of EV charging industry. What a standard EV charger will do is simply draw power from the grid and charge the EV’s battery at a full load until it is full. This might result in a huge impact on the existing Australian electrical infrastructure if the number of operating ev chargers is enormous.
At Commercial Properties, charging multiple Electric Vehicles at their maximum power for a long period places a heavy burden on the electrical infrastructure (and the wallet of the property owner). Moreover, this system may require an upgrade of the electrical system in the building which becomes very expensive and therefore prohibitive to many customers. This is where EVSE Load Management has been created to solve this problem.

What is Load Management

Load Management is very popular feature of the EO Genius Intelligent Charging range because of it’s market-leading load management functionality. Unlike a standard EV charger such as our EO Basic EV Charger or our EO Mini EV Charger, an intelligent EV charger is one which can be controlled and monitored by a controller via Software or a Cloud database.

Load Management simply means that users can specify the amount of power used for charging EVs. If the power demanded by the charging system exceeds the power supply from the grid, the controller of the system, with Load Management-enabled, will re-calculate and modify the available at each charging point of the system.

For example:

From the power source, the available Current used for a 32A, 3.6kW charger is 40A

  • If there is 1 vehicle presented, then it can charge at 32A
  • If there are 2 vehicles presented, then each car is charged at 20A
  • If there are 3 vehicles presented, then each car is charged at 13.33A
  • If there are 4 vehicles presented, then each car is charged at 10 A

This ensures that the EV charging system will not exceed limited power set up by the building’s owner. Therefore, the risk of any damage to the expensive electrical infrastructure is totally eliminated.

Advanced Load Management Capabilites are central to the market leading EO Genius EV Charging Solution

There are 3 options supported by Load Management

  • Static Load Management
    Static load management evenly distributes a charging power pre-set for all charging stations across several connected electric cars, no matter how many of the individual electric cars are actually charging. Every charging station is allocated the same charging power within the limited power’s range.
  • Scheduled Load Management (Scheduling)
    The available charging power is divided up according to different times in a day. This allows you to take advantage of time of use tariffs (TOUs) and allocated more supply at times when the site supply is more readily available.
  • Active Load Management (ALM)
    Active load management (ALM) is one of the EO Genius’ most advanced features which separates it in the Australian market as it does not need a charging power pre-set. Instead, the charging power’s range is dynamically modified by the controller based on the power consumption in the entire building.

If the power consumption in the building decreases, then there is more electricity available to charge the electric cars. In contrast, if the power consumption in the building increases, then there is less electricity available to charge the electric cars.

Why Load Management is important to Commercial Properties:

At every Commercial Properties, a stable electrical power supply is compulsory. Nobody wants a sudden blackout due to an overload of the power system.

As mentioned before, each individual EV charger consumes a large amount of energy during its operation. A system with 10 EV chargers operating simultaneously could result in blackout or worse, the corruption of the electrical infrastructure in the building if the electrical draw surpasses the available supply.

Therefore, Load Management can be considered as a means of protection for the electrical system of the building with the EV charging system.

The benefits of Load Management in a Commercial property can be listed as:

  • Protecting the property’s electrical Infrastructure
  • Eliminating the risk of overloading
  • Ensuring efficient operation for all EV chargers within limited power sources.
  • Saving cost for upgrading electrical infrastructure
  • Saving cost of electricity bill
