10+ Metrics for Measuring Fleet Electrification Success

5 Min. Read

• Cost Metrics: Track cost per mile, average cost per delivery or home visit, charging cost per kWh, maintenance, and insurance rates to evaluate the total cost of ownership (TCO) and ROI of electric vehicles (EVs) compared to internal combustion engine (ICE) vehicles.
• Charging Infrastructure Efficiency: Monitor average charging time per session, state of charge at route start, wait times, charger uptime, utilization rate, and maintenance costs to optimize EV charging strategy and infrastructure performance.
• Operational and Satisfaction Metrics: Assess route adherence, driver behavior (acceleration, speed, braking), accident rates, and driver/customer satisfaction through surveys to ensure operational efficiency and a positive EV experience.

How do you measure the success of a fleet electrification project?

Adopting electric vehicles reduces fleet fuel costs and unlocks other benefits, such as access to advanced telematics and a better brand image.

Without the right framework to measure your progress, these benefits remain invisible. It’s why you need to track the right metrics or key performance indicators (KPIs).

4 Fleet Electrification Success Metrics for Tracking Performance and Savings

Adding EVs to your fleet is an upfront investment, and you should prepare to pay a little more than a traditional ICE vehicle for a comparable model.

Once your new EVs are on the road, you can look at performance metrics to determine how quickly you get that upfront investment back. These numbers can also inform which EV models have the best ROI for future purchases.

The first EV-related metric to track is your cost per mile. This will help you determine how much fuel you’re saving and possibly compare charging options. You can also look at the average cost per delivery or home visit.

If you need to compare EVs to ICE vehicles, calculate the average charging cost per kWh and translate this number into an MPG equivalent.

You should also keep a close eye on EV maintenance and repair costs so you can compare these numbers to what you spend on maintenance for your ICE vehicles. If your insurance company is billing differently for EVs, include your new insurance rate in the KPIs you track for a more accurate overview of your costs.

These different metrics are important for calculating your total cost of ownership (TCO) for your electric fleets and communicating savings to the decision makers in your organization. They can also help you budget better if you’re electrifying your fleet in phases.

6 Metrics for Your EV Charging Infrastructure

You can’t measure fleet electrification success without looking at EV fleet charging. Assess how effective your charging strategy is by looking at the average charging time per session and your EV’s state of charge at the beginning of a route. If applicable, you should also look closely at wait times for using the chargers.

These three fleet electrification KPIs will help you determine how effectively you’re using the chargers you invested in. You can go further with three additional metrics, including charger uptime, utilization rate for your chargers, and EVSE maintenance and repair costs.

If you have a time-of-use agreement with your electricity provider, track your EV charger utilization rate more closely to make sure you’re doing most of your charging when time-of-use electricity rates are low.

According to Jake Lowe, Qmerit’s Director of Fleet & European Program Operations: “These numbers matter because they show whether your fleet charging infrastructure still reflects your needs. The charger utilization rate should go up as you add more EVs to your fleet, but things like wait times going up or charging downtime becoming more frequent can indicate issues.

Beyond collecting these numbers, talk to your drivers about charging to make sure you’re offering a smooth experience.”

On the Road: Fleet Electrification Success Metrics for Operational Efficiency and Satisfaction

What do day-to-day operations look like for your electric fleet? You can get a comprehensive picture with the following metrics.

Look at how closely drivers follow the planned routes by tracking your schedule and route adherence rates. Frequent changes can indicate you need to optimize route differently and better account for charging needs and EV ranges.

Driver behavior analytics are even more valuable with EVs. These vehicles support advanced telematics applications and allow you to track things like acceleration, average speed, and excessive braking. You can then use these insights to calculate a driver score and hold your team members accountable and foster a culture that values safety.

Speaking of safety, you should also track accident rates. Driving an EV feels different, and it might take a while before drivers are comfortable with instant torque and rapid acceleration. A low accident rate indicates your training efforts are paying off, while a spike in accidents means you should slow down and let your drivers familiarize themselves with EVs in a safe environment before heading out on their usual routes.

Loew adds: “Lastly, you can gather a mix of qualitative and quantitative data with surveys for your drivers and customers. Wait until you’ve had EVs on the roads for a few months and ask everyone how they feel about this change. You can ask drivers to grade their experience on a scale of 0 to 10 or ask customers if the EVs mean they perceive your brand differently.”

Tracking these metrics gives you better visibility over your fleet electrification project and helps you optimize your ROI as you scale and adopt more EVs.
