How to Choose the Best EV Charging Model for Your Hotel or Retail Business: A Comprehensive Guide

As electric vehicles (EVs) continue to rise in popularity, businesses with parking facilities must consider installing EV charging stations to meet growing demand. EV drivers prefer to patronize locations where they can charge their vehicles, making charging stations a key asset for attracting and retaining this valuable customer base. If you’re looking to future-proof your business, installing charging stations is essential.

However, you’ll need to decide how to manage your EV charging stations. There are several models available, each with its own set of advantages and drawbacks. The best option depends on your business goals and the needs of your customers.

Let’s explore five primary EV charging models that retail locations such as hotels and stores can implement.

 

1) Charging by Kilowatt-Hour (kWh)

One straightforward approach is to bill customers based on the kilowatt-hours (kWh) they use. This model allows you to recover the costs associated with the energy consumed by your charging stations.

Example:

• Set price: $0.25/kWh
• 32 kWh x $0.25/kWh = $8.00

 

2) Charging by Time

Another effective method is to charge by the time a vehicle is connected to the charger. This model encourages drivers to move their vehicles once they’ve finished charging, freeing up the station for others.

Example:

• Set price: $3.00/hour
• 32 kWh charge (at 8 kW output) = ~4 hours
• 4 hours x $3.00/hour = $12.00

 

3) Combination Charging (kWh + Time)

For those who want to combine the benefits of both kWh and time-based billing, a combination model might be ideal. This approach charges drivers for both the energy consumed and the time spent at the station.

Example:

• Set price: $0.20/kWh + $1.50/hour
• (32 kWh x $0.20/kWh) + (4 hours x $1.50/hour) = $12.40

 

4) Flat Rate Charging

A flat rate model is the simplest way to collect revenue from your charging stations. By charging a single, fixed fee for using the charger, you eliminate the need for complex billing calculations.

Example:

• Set price: $10.00 per charge

 

5) Free Charging

For businesses looking to offer an extra convenience to their customers, providing free charging is a straightforward, customer-friendly option. Free charging is an excellent way to attract EV drivers to your location.

Example:

• Set price: FREE!

 

Pros and Cons of Each Charging Model

Charging Model	Pros	Cons
Charging by kWh	Simple for both the site host and EV driver Directly recovers energy costs	Does not prevent vehicles from “camping” May not be allowed in all markets
Charging by Time	Legally permissible in most regions Discourages “camping” when full	Favors vehicles with faster onboard adapters (faster charging=lower cost)
Combination Charging	Balanced and fair billing method Discourages “camping” while charging for energy	Finding the right pricing balance can be challenging Slightly favors faster onboard adapters
Flat Rate Charging	Simplifies revenue collection with transparent pricing Works well with network-ready stations	Does not account for actual energy used (may not seem fair) Doesn’t discourage “camping”
Free Charging	Highly attractive to EV drivers Minimal station management and operational costs	No revenue generation Fewer advanced Smart Charging features available

Choosing the right EV charging model for your business depends on your specific goals and the needs of your customers. Whether you opt for kWh-based billing, time-based billing, a combination of both, a flat rate, or free charging, each model has its benefits and challenges.
