How an EV Power Management Device Can Save Energy and Money

The EV charging experience for both property managers and EV drivers is defined by an efficient power management system for EV charging, sometimes referred to as “network management.” These services include software and tools bundled with EV chargers that streamline and optimize the charging process while meeting the needs of both building operators and EV users. An EV power management device​ ensures your building’s electrical infrastructure can support a growing number of EV chargers without expensive installation costs and upgrades.

Understanding the difference between load sharing and load shedding is essential when selecting the right EV power management device. For EV charging in condo buildings, effective EV load management is crucial to optimize charging capacity and ensure equitable power distribution among residents. For EV charging in commercial buildings, a proper EV load management system helps maximize efficiency and meet the demands of multiple EV users without overworking the electrical infrastructure.

What is an EV Power Management Device?

An EV power management device dynamically adjusts the output of each charge point based on the total electrical capacity of the building and the number of vehicles plugged in. This allows property managers to future-proof their infrastructure by accommodating more chargers without overwhelming the existing electrical system.

There are two primary approaches for an EV power management device: load sharing and load shedding.

How Does Load Sharing Work?

Load sharing efficiently distributes the available electrical capacity among all vehicles connected to the charging network through an EV power management device. Rather than prioritizing one vehicle over another, the system divides the power output dynamically, ensuring all EVs receive a charge.

When multiple EVs are plugged in, the system calculates the available electrical capacity and shares it proportionally across all chargers. This ensures that every vehicle is charged, even if the total demand approaches the building’s maximum electrical capacity.

Here is an example of EV charger load sharing with four 32-amp EV chargers installed on a panel with only 120 amps available:

Benefits of Load Sharing

• Maximized Capacity: Supports multiple EVs without exceeding your building’s electrical limits.
• Improved User Experience: Ensures all vehicles receive a charge, even during peak demand. 
• Future-Proof Solution: Reduces the need for costly electrical upgrades as EV adoption grows with a scalable EV charging infrastructure.

At metroEV, our EV charging software uses load sharing to ensure every EV gets the charge it needs, providing a seamless experience for drivers and property managers.

How Does Load Shedding Work?

Load shedding operates differently by prioritizing certain vehicles at the expense of others. When electrical capacity reaches its maximum limit, the system “sheds” or stops charging one vehicle to allow another vehicle to begin charging. While this method can manage capacity, it often leaves some vehicles without a charge.

When demand exceeds electrical capacity, the system stops charging one or more EVs to make room for new vehicles. This prioritization can create an inconsistent charging experience for EV drivers, as some may be left without power.

Here is an example of EV charger load shedding with four 32-amp EV chargers installed on a panel with only 120 amps available:

Drawbacks of Load Shedding

• Inconsistent Charging: Some vehicles may be left without a charge, frustrating drivers.
• Less Efficient: Fewer vehicles are charged simultaneously.
• Poor User Experience: Interruptions in charging can impact overall satisfaction.
