EVSE INFRASTRUCTURE PRESENTATION

EVSE Infrastructure – What it means and communicating it.

Audience:

• Ambassadors for Electric Vehicles

• Those wishing to promote Electric Vehicles and explain to others.

• Those seeking basic understanding of Electric Vehicles and the terminology used.

Intro:

With the recent success of Tesla introducing all electric vehicles that have features found in current fuel powered vehicles including substantial range before recharging; there are now many people who are now considering making a transition from a fuel powered vehicle to a battery powered vehicle. Indeed, many are motivated because of environmental and geo-political reasons. However, they have been dissuaded by several factors:

• Range anxiety.

• Cost of vehicle.

• Where to charge the vehicle.

• Ability to charge the vehicle at home or their work place.

• Criticism from their friends, colleagues and co-workers.

This presentation aims to communicate answers and explanations that can be used to encourage and guide them making these important decisions. In particular, the transition from refueling a vehicle to recharging a vehicle; what that means on a day to day basis and the expectations. This is commonly referred to as Electric Vehicle Supply Equipment (EVSE) Infrastructure.

Promoting Electric Vehicles:

It is important when presenting a new technology to someone who is not familiar that you don't confuse them and over load them with information, facts and techno-speak!

Be prepared to answer negative comments rationally and logically. It maybe that your audience has been mis-led or even had some bad experiences with electric vehicles; perhaps their expectations were not met. Remember, this is a large change for transportation; it has been compared to changing from horse drawn vehicles to powered vehicles.

Have information readily at hand:

• list of commonly asked questions and answers.

• List of reputable reference sources.

• Experiences of local people they may know.

• Local, accessible charging points.

Some other points to consider such as those in an article titled “Guiding Principles to Promote Electric Vehicles and Charging Infrastructure”¹ from the government office of Energy Efficiency and Renewable Energy. “On July 21, 2016, the White House announced that nearly 50 industry members signed on to Guiding Principles to Promote Electric Vehicles and Charging Infrastructure. This commitment signified the beginning of a collaboration between the government and industry to increase the deployment of electric vehicle charging infrastructure.” This significant commitment by the Administration to enhance electric vehicle use and charging infrastructure that is available to all Americans.

EVSE:

Explain carefully that EVSE means Electric Vehicle Supply Equipment. Be sure to stress that it is NOT a piece of charging equipment. It's primary function is to provide power to a vehicles built in charging system and to manage the delivery of that power to the vehicle's charging system. The electric vehicle owner will have to consider their charging options which can be broadly classified:

Places where you can charge up

• At Home

• Public Locations

• At Work

Charging Hookups

Categorizing two major differences:

1. Unsecured 'free' connections - You aren't charged to take the electricity. These are typically found in secure locations such as your garage or possibly at your work place.

2. Some kind of authentication to purchase electricity - Either by card or by account number. Before you can release the cordset from the station you have to release it which probably involves starting a transaction using a credit card. Note that many new points of payment do not use the traditional credit card slot, but use a wireless proximity technology that is denoted by a small symbol on your card.

Pictures of typical public installations - Maybe free / May have to pay

Pictures of typical shared installations in apartment complexes - Maybe part of common charges or maybe part of your rent

Pictures of typical residential installations - typically free(!)

Pictures of workplace installations - Maybe free / or part of compensation package or..../

The International Association of Electrical Inspectors (IAEI) identified the role that electrical inspectors, their members, will play as the charging infrastructure is developed. The main consumers are the individuals that expect to be able to plug the vehicles in at their homes. Indeed, as the market rapidly evolves, there will be challenges to meet the needs of consumer expectations...

INFRASTRUCTURE CHANGES:

As many people are probably wondering, with the increasing number of electrical hookups being installed; how will that impact the current infrastructure and the delivery of electricity be impacted.

The utility companies will need to know about these additions to the system! Remember in the summer time when many air conditioning units are switched on; we begin to experience power outages as the system fails to deliver the power required. In a similar manner, we could experience the same situation. Typically utility companies like to have a constant load presented to their system and to encourage that they provide incentives (or dis-incentives!), to consume power at different times. Indeed, ComEd has flexible tariff programs that charge you according to the time of day and other considerations. The meters that they are now installing, and retrofitting are called SmartMeters which permit you to view your electricty consumption 24/7.

As more vehicles transition to Plug in Electric, battery powered from fuel powered; the energy required will have to come from somewhere! In some parts of the world, there is plenty of solar, wind or hydro power available. Additionally, the grid infrastructure will need to be upgraded to accommodate the additional power delivery required. Advances in battery technology offer one form of help as advanced battery storage solutions can be added to the grid to provide a form of load balancing to reduce the peak demands.

It is important that we embrace these necessary changes and encourage everybody to participate in the changes to avoid unnecessary power outages! We don't want the equivalent of a fuel crisis!
