Fleets are under significant pressure to become more sustainable by going electric. However, the implications of going electric for a professional fleet are complex and costly, and include massive operational challenges.

Planning ahead is the only way to keep sight of your fleet’s objectives, maintain the level of service your business needs, and make the shift to EVs, all at the same time.

The most effective way to plan complex professional fleet operations is by simulating them – performing “experiments” before buying a single new vehicle or installing a charger. Careful, data-driven planning can save fleets from incurring the double penalty of fixing expensive mistakes after the fact.

Autofleet recently released a self-serve version of its Fleet Planning Simulator that allows companies such as Terawatt, Scania, and Ford to use real trip or demand data, alongside telematics and actual traffic information to simulate the dynamics of an EV fleet and the required infrastructure.

Here is a quick look at the power of simulations.

The Test Fleet

Meet ACME, Autofleet’s fictitious fleet of technicians providing service for home appliances. We used aggregated trip data from several sources to create ACME’s fleet data with the following specifications:

  • Fleet size: Just over 300 vehicles.
  • Operating in: 10 U.S. cities
  • Number of service calls: 250-600 per day
  • Fleet composition: 100% ICE vehicles from over 20 different OEMs

Process: We uploaded the data into the simulator (it’s actually as simple as uploading a file) and let it do the math.

What we wanted to learn:

  • What is the optimal mix of vehicle types?
  • What is the most suitable charging strategy for the fleet?
  • How will electrification affect the fleet’s carbon footprint?
  • How to de-risk the switch to EVs effectively?

First Thing First: Optimizing the Fleet to Make Sure We Get the Greatest Returns

The first step to electrification is actually to make sure the current fleet is optimized. The transition to EVs can be pricey, but it offers much better ROI when the vehicles are utilized the most — leveraging the lower energy and maintenance costs of an EV to offset the high initial cost and reduce total cost of ownership (TCO).

In our test fleet (based on real data) and using Autofleet’s Route Optimization, we were able to serve the same demand with 20% fewer vehicles — each covering more distance.

A smaller fleet with higher utilization makes the TCO of EVs more attractive compared to the existing ICE vehicles. This is because the fleet is expected to cover more miles, and thus the much lower cost per mile of EVs plays a bigger role when calculating the total cost of ownership.

What Vehicle Mix Will Yield the Best Results?

Electrification becomes even more attractive financially when it is coupled with route planning and optimization. However, we had to ensure that electrification would not disrupt existing schedules for midday recharging. That is, routes were optimized for maximum utilization, yet they needed to complete the full route without exceeding the projected range.

We found that most vehicles in our simulated test fleet can operate the whole day without stopping to top off their batteries.

That was not always the case, however, and some vehicles did need charging during the day. For example, the graph below shows that some vehicles in City 1 and City 7 needed to top off their batteries during the day, which may entail long breaks and detours.

What Will It Cost? Assessing the Financial Implications of Moving to EVs

In order to get a better understanding of the financial implications of adopting EVs, we dove deeper into the data of one particular city to find out the best EV charging policy that will allow us to maintain the current level of service and expenses.

The different charging options are:

  • Depot or home overnight charging using level 2 AC charging stations.
  • Public rapid DC charging stations (from the likes of Electrify America, EVgo or ChargePoint, for example).
  • Or even an on-demand mobile charging truck that can deliver DC charging to the vehicles at their location.

Since the optimized routes strategy we chose does not require topping off the batteries during the day in this city, using Level 2 AC chargers with overnight charging is the best solution. This can be done either by using a depot or by compensating workers for their charging costs at home.

The energy cost savings is easily calculated by looking at the difference between the cost of powering ICE vehicles (using gas prices) and EVs. That cost difference is the leeway ACME has above the current costs, to either cover higher leasing costs or improve its bottom line.

As is to be expected, even a partial switch to EV reduces the carbon footprint of the fleet significantly.

Simulations Can Reduce Costs and Overhead

There is no one-size-fits-all answer to the electrification question. Every fleet has different needs and different considerations affecting TCO. It is not uncommon to discover that a mix of EV and ICE assets may be the best plan in the present time.

Planning requires accurate tools like the one offered by Autofleet to avoid costly mistakes. Successful electrification projects we saw recently were backed with data to help streamline the transition without letting the service levels slip.

Start by answering the big questions - who and what does the fleet serve? What’s the impact on the TCO and emissions? How do you maintain the level of service your business offers?

Then test different scenarios, fleet composition, and optimizations that will be tailored to your needs, increasing your chances of success.
