DLM Use cases

The eMabler platform’s Dynamic Load Management (DLM) system is designed to optimize charging behavior across a wide range of use cases, from urban garages and residential complexes to mixed fleet sites. By utilizing real-time data, adaptive charging strategies, and dynamic load adjustments, DLM ensures that the charging infrastructure operates efficiently, safely, and cost-effectively under various conditions. Below are some key examples of how DLM can be applied across different environments.

Urban Garage

In urban environments, such as parking garages or commercial buildings, the need to balance electrical load between EV charging stations and other electrical systems (like HVAC and lighting) is crucial. Here's how DLM can help:

• Scenario:

  • Fuse Rating: 250A

  • HVAC Load: 90A (spikes due to temperature changes or high demand)

  • MaxCurrent for EV Charging: Initially set to 250A, but after the HVAC system spikes, available capacity for EV charging decreases.

• How DLM Works:
  As the HVAC load spikes to 90A, the available power for EV chargers is reduced, leaving only 157A for EVs (160A - 3A of load margin). The Dynamic Load Management system adjusts the EffectiveMaxCurrent for the EV chargers in real-time, reducing the load to 157A and ensuring that the total power demand does not exceed the fuse rating of 250A. This prevents overloading of the electrical system and maintains safe operation of both the HVAC system and EV chargers.

• Outcome:
  By dynamically adjusting the charging power based on real-time system demands, DLM ensures that charging stations and other critical systems (like HVAC) can function simultaneously without risking overloads. This is especially important in urban settings where space and electrical capacity are often limited.

Residential Complex

In residential settings, such as apartment complexes, DLM helps to optimize energy usage and reduce electricity costs by aligning charging behavior with cost-saving strategies. The goal is to ensure that EVs charge during low-cost hours, helping residents take advantage of cheaper electricity rates.

• Scenario:

  • Cost Saving Policy Applied:
    A Cost Saving charging policy is activated, which ensures that charging only occurs during off-peak hours when electricity prices are low (typically at night).

• How DLM Works:
  The system monitors electricity prices in real-time and compares them to a predefined cost-saving threshold. Charging is paused when prices are high (e.g., during the day) and resumes when the price falls below the set threshold (e.g., at night). The system automatically adapts to market price fluctuations without requiring any manual intervention, ensuring that residents can save money on charging costs.

• Outcome:
  By using the Cost Saving policy, residents in the complex can charge their EVs only during the night when prices are typically lower. This reduces the overall cost of charging and maximizes savings, making EV ownership more affordable.

Mixed Fleet Site

At a mixed fleet site, there may be a combination of public chargers for customers and dedicated fleet chargers for vehicles in a corporate or industrial fleet. Managing these different charging needs is critical to ensure both operational efficiency and cost optimization.

• Scenario:

  • Public Chargers: Set to Always Charge mode to ensure that critical fleet vehicles always have sufficient charge, regardless of electricity prices.

  • Fleet Chargers: Set to Balanced mode, where charging is paused when the spot price is high and resumes when the price drops.

• How DLM Works:

  • Public Chargers: The Balanced charging policy automatically adjusts the charging schedule based on market prices. Charging will pause when prices are high and resume when they drop, helping to reduce the overall charging cost for public users.

  • Fleet Chargers: The Always Charge policy ensures that critical vehicles (e.g., delivery trucks, emergency vehicles, or other essential fleet assets) are always charged, even if the market price is high, ensuring operational continuity. The system will prioritize fleet chargers, ensuring that their power demand is always met, even when prices increase.

• Outcome:

  • The Balanced chargers help optimize cost by charging only when it's most economical, reducing the total energy cost for public users.

  • The Always Charge policy ensures that the fleet can continue operations without interruptions, guaranteeing that critical vehicles are always ready for use.

  • This configuration allows the site to support both cost-effective public charging and priority fleet charging, maximizing operational efficiency and minimizing downtime.
