EV Charging Load Management

What is Load Management?

Load Management – simply put – is when you use software to control your EV charging.

Standard home EV chargers use the power supply from the house to charge their vehicles. Nice and straightforward!

But what do you do when you own a building where several EVs that all need charging at the same time? That could make for one very big queue!

For commercial buildings, workplaces, apartments, and things like that, that’s where load management makes a big difference.

Load management is the process of balancing the supply and demand of electricity on the grid. By controlling the power drawn by devices, such as EV chargers, it prevents blackouts and brownouts, and can also save money by reducing the need for expensive infrastructure upgrades.

Commercial Load Management

Charging multiple EVs at the same time can put a lot of strain on your electrical systems, and it could lead to an overload. Not good! Load management allows you to specify the amount of power used, and it can adapt to different circumstances as they arise. If the power required exceeds what’s available from the grid, then load management evaluates and modifies the flow of power for safety and performance.

For example, if you own an apartment building with multiple car points outside, it will balance out the electricity being used, and the risk of damage or overload to the charging infrastructure is minimised. For four vehicles who all need of charging at the same time, and the current used for a 32A 3.6kW charger is 40A, then each car would be charged at 10A.

Load Management Can Save Your Bacon!

If installing and maintaining charging points at your business is an big part of your future business plans, then making the system is reliable and efficient is top priority.

You can’t risk an overload or blackout when you have commercial vehicles to charge. A loss of power could mean a loss of business revenue and unexpected downtime!

With Load Management, you can rest assured that your electrical system can handle the demand of EV charging without overloading, even at your busiest times.

Save money with Load Management

When handling multiple properties, each with multiple EV chargers, you need to know your set up is both efficient and reliable.

Myenergi’s zappi monitors the electricity demand and supply in real-time and can detect when the electricity demand is high and when it is low.

Each Zappi communicates wirelessly with its buddies within the set up to dynamically and constantly adjust the charge rate, according to how much power is available within the building. This is known as load shedding. By reducing the charging rate, the smart EV charger ensures that the total electricity demand is within the available supply.

Simply setup the first zappi as master point, then pair additional chargers as the demand for charging in your building increases.

Different Options Available

Static Load Management

Even distributes the power available via a pre-set system across all EVs being charged at the time, with each vehicle receiving the same amount of power

Scheduled Load Management

Depending on the time of day, EVs will receive different charging power – allowing for Time of Use Pricing and when more power is generally available.

Active Load Management

The power available for charging is determined by the power usage of the connected building and can be set by the owner of the premises. At times when the building requires more power, less will be allocated to the EV chargers, and vice versa.
