Installing Electric Vehicle Chargers

How To Install EV Charging Stations At Your Business

So, you are interested in installing electric vehicle chargers at your corporate office for your employees or at your business for customers.
EV Charging Pedestal
It is wise to add Level 3 charging stations because they offer a number of benefits depending on the intended user.

  • They can attract new business
  • They increase the average time customers spend at your location
  • They provide an incentive to employees while demonstrating your commitment to the environment

Depending on the output capacity of the Level 3 charger station, it can fully charge an empty battery in as little as 7 minutes for a small passenger car to 50 minutes for a light commercial vehicle.
The typical installation cost is in the range of $30,000 - $250,000 per location depending on whether it is a single ev charging pedestal or many pedestals.
For this reason, it is important to carefully consider all aspects of the system in order to get the most benefit from this investment.

2. Establishing Rules for the EV Chargers

Time LimitsEstablish time limits on chargers to ensure efficient use of chargers.
Remind users of time limits
Multiple UsersProhibit users from disconnecting other users’ electric vehicles.
Establish a protocol for users who pass their allotted time on a charger
Improper UseRemind users of the importance of charging safely.
Ensure users store charging cord properly by providing signage for proper storage

3. Providing a Safe Environment for EV Charging

• Installl only charging equipment has been rated and listed by a Nationally Recognized Testing Laboratory (NRTL) such as UL, CSA, or ETL
• Schedule a regular maintentance and test interval for the charging station
• Manage charging cords to minimize trip hazards for users
• Prevent charging cord damage by keeping the cord on its holder
• Report damage immediately to the appropriate personnel

4. Should We Charge to Charge?

• Payment and payment methods are decided by the charging station owner
• Requirement payment may help recover equipment and usage cost
• Options include: charge per kWh used, time parked, or a flat fee

5. Protecting Your Investment? Surge Protectors for Electric Vehicle Charging Stations

Today’s increased reliance on very sensitive electronics makes surge protection an important topic for Electric Vehicle (EV) Charging Systems.
The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges.
In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©.

This article discusses the various types of EV Charging Systems and Electric Vehicle Supply Equipment (EVSE) to help you develop a comprehensive surge mitigation strategy.
Each section will provide a recommendation on exactly which EV surge protector to use for your equipment and where to install these Surge Protective Devices for EV Chargers.

Where To Protect a Level 3 EV Charging Station

EV Public Charging Stations

Power Source : DC Fast Charging (DCFC)

The fastest charging method (30 minutes for 124 miles) but also the most costly.
These are connected to the power utility grid with an AC to DC power conversion module.
The output DC voltage range is from 120Vdc to 1000Vdc with higher voltages expected in the future.
In addition to the AC source, these systems can be fed or supplemented with by a photovoltaic power plant or energy storage system.
