2. Project Introduction

3. 3
Project Objectives
• Engaging stakeholders to determine
the barriers with MUD charging
• Demonstrating innovative
technologies addressing the barriers
• Compiling project findings in a toolkit
• Disseminating the toolkit
Impact on Barriers
•Collect and analyze data on existing
MUD charging stations utilization
•Demonstrate technologies that
reduce MUD charging costs and ease
management barriers
•Create an outreach tool and engage
MUD owners, managers and
residents

7. • Increasing annual usage
trends as expected
• 12.2 hour average session; 3.6
hours average charge duration
• Energy profiles similar for both
longer and shorter sessions
• Highlights opportunity to
increase utilization

9. MUD Decision-Making Process:
• Apartment Building – simpler process with owner and management ruling
• Condominium – complicated and political process of association mixed with local
jurisdictional complexities
Key Barriers Identified:
• Education and Awareness Barriers
• Financial Barriers
• Electrical Preparedness Barriers
• Building Physical and Design Barriers

Barrier
Number
of
Responses Descriptions and Examples
Information and
education
15
-Chicken-and-egg problem for PEV adoption and EVSE need
-Need proper information for building owners, managers, and HOA on features and benefits
HOA related 17
-Common area management
-Association approval difficulties and homeowner buy-in
-A few stalls far from electrical panel will be extremely costly
Parking limitation 15
-Deeded parking and limited parking spaces
-Parking garage or spaces far from electrical panel, increasing costs
Parking operation 8
-Drivers do not unplug when done charging
-Outside free-riders problem
Capital constraints 8 -Not enough funding and/or may need grants or incentives
Electrical related 12
-Older building may not have enough electrical capacity and require costly upgrades
-Distance of electrical panel from garage increases installation costs
-Potential need to conduct expensive load study
Cost of installation 14
-Installation cost of running electrical circuit and conduit for EVSE
-Installation cost for electrical panel or service upgrade
O&M ongoing cost 15 -Power management and network subscription fees
Network signal 4
-Weak cellular signal in garages
-Expensive to run internet cables and install Wi-Fi router or cellular repeaters
