EVSA assessment results
Learn how to read each tab in your assessment results.
The assessment recommendation report provides detailed summaries for the recommended EVs. To open an assessment, click its tile on the Electric Vehicle Suitability Assessment page.
Each assessment has three tabs. Select a tab to view its details.
- Summary: Charts that summarize the assessment results. For more information, see Summary tab charts.
- Recommended EV replacements: The vehicles that have a suitable EV recommendation. For more information, see Recommended EV replacements.
- Fleet vehicles without EV fit: The vehicles that don't have a suitable EV recommendation.
Fleet vehicles without EV fit
The table under Fleet vehicles without EV fit lists the vehicles that don't have a suitable EV recommendation. A vehicle is listed when:
- The EV can't meet the daily driving range requirements, compared with the EV range under local monthly conditions.
- The EV's lifetime savings aren't within a predefined limit compared with an equivalent non-electric vehicle.
To change how many en-route charging events are acceptable, see Assessment preference options.
Summary tab charts
Review the charts that compare cost, fuel, and emissions for your assessment.
Recommendation summary
The Recommendation Summary chart gives a quick overview of the assessment recommendations. It displays the number of vehicles assessed and the number of recommended vehicles by vehicle type: battery electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs), and vehicles recommended for replacement by new non-electric vehicles.
For each vehicle selected when you created the assessment, an EV is recommended if both of the following are true:
- The EV can meet the daily range requirements of the vehicle without charging during the day beyond the allowed limit.
- The lifetime cost of the EV is within the allowed limits compared with an equivalent non-electric vehicle.
Lifetime replacement cost
The Lifetime Replacement Cost chart compares the lifetime costs of two scenarios:
- Recommended EVs: The sum of the costs of the recommended BEVs and PHEVs.
- Comparable ICEs: The sum of the costs of replacing the fleet vehicles that have a suitable EV replacement with new internal combustion engine (ICE) vehicles.
The total cost has the following categories: Procurement, Maintenance, Fuel, Electricity, and Other.
The Other category includes vehicle registration and taxes, insurance, and low emission zone charges. The lifetime is based on the number of years that you select on the Preferences step.
Annual fuel and electricity
The Annual Fuel and Electricity chart compares the annual energy costs or fuel volume of two scenarios: Recommended EVs and Replacement Candidates.
When you select Cost, the chart calculates the cost for each scenario as follows:
- Recommended EVs: The sum of the fuel and electricity costs of the recommended BEVs and PHEVs, averaged over one year.
- Replacement Candidates: The total fuel costs of the selected fleet vehicles that have an EV replacement candidate, averaged over one year.
When you select Fuel Volume, the chart calculates the amounts for each scenario as follows:
- Recommended EVs: The sum of the projected fuel consumption of the recommended PHEVs, averaged over one year.
- Replacement Candidates: The total projected fuel consumption of the selected fleet vehicles that have an EV replacement candidate, averaged over one year.
The EVSA uses the actual fuel consumption from the vehicle when possible. If a vehicle doesn't report fuel consumption through the GO device, the EVSA uses a default fuel economy value for that vehicle.
Annual CO2 tailpipe emissions
The Annual CO2 Tailpipe Emissions chart compares the annual carbon dioxide tailpipe emissions of two scenarios:
- Recommended EVs: The total projected CO2 emissions of the recommended PHEVs, averaged over one year.
- Replacement Candidates: The total CO2 emissions of the vehicles that have an EV replacement candidate, averaged over one year.
BEVs aren't included because they don't emit carbon dioxide.
Recommended EV replacements
Review the details that the EVSA lists for each recommended EV replacement.
The table under Recommended EV replacements lists all vehicles that have a suitable EV recommendation, either a battery electric vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV). For each vehicle, the table displays the following data:
Column | Description |
|---|---|
Vehicle name | Name of the existing non-electric vehicle. |
Year, Make, Model | Year and model of the existing non-electric vehicle, from MyGeotab. |
Vehicle type | Vehicle type of the existing non-electric vehicle. |
Recommended EV | EV recommended as a replacement for the existing non-electric vehicle. |
Powertrain | Powertrain of the recommended EV, either a BEV or a PHEV. |
En-route charging events due to distance | The number of days when the BEV can't meet the range requirements without charging during the day, either because of long trips or because it has insufficient charging time before the trips. |
Lifetime savings | Projected savings of the recommended EV compared with a new non-electric replacement. |
Click View details after the last row to open more information about Range Assurance and Lifetime Cost. For more information about range, see Monthly range assurance.
Vehicle size variation
If the EVSA recommends an EV that isn't the same size as the existing vehicle, the table displays a Vehicle Size Variation note. For more information about how the EVSA matches sizes, see How the EVSA works.
Monthly range assurance
Learn how the EVSA compares the range of a recommended EV with monthly driving and temperature.
The Monthly Range Assurance chart helps you understand the range capability of the recommended EV throughout the year, based on the driving activity of the current internal combustion engine (ICE) vehicle.
For every calendar month, the chart shows the following data points:
- The longest daily distance driven by the selected ICE vehicle.
- The range of the recommended EV, which accounts for the average monthly temperature where the vehicle is driven.
- The monthly average temperature of the region where the vehicle is driven the most.
If the assessed vehicle doesn't report trip data for 12 calendar months, the EVSA replays trips from other months to cover the entire year. The months that use trip data from other months are labeled Assumed Data on the chart.
The accompanying Monthly en-route charging events chart tracks how many times the recommended EV would need to charge en route before it could return to a location where it can charge.
By default, an EV is considered the best fit when no en-route charging events are required in any calendar month. To change this, set the number of acceptable en-route charging events per month with the En-route charging setting. For more information, see Assessment preference options.
EVSA warnings and exceptions
Review the warnings and exceptions that the EVSA can raise while it processes fleet data.
The following table describes the warnings and exceptions that the EVSA can encounter while it processes fleet data. If a warning or exception is raised for a fleet vehicle, you can review it in the detailed recommendation table.
Warning or exception | Description |
|---|---|
No data from vehicle | The MyGeotab API didn't return trip data within the assessment time frame. The vehicle is considered to have no suitable EV fit. |
Not enough data | Less than 3 weeks passed between the vehicle device activation and the report end time. The assessment runs and a warning is raised. |
No fuel data | The vehicle doesn't support fuel consumption. The assessment runs using a default fuel economy value for the vehicle, and a warning is raised. |
VIN missing | The vehicle make, model, and year aren't available because the VIN is missing in MyGeotab. The assessment runs and a warning is raised. |
Unidentified vehicle | The vehicle make, model, and year aren't available because the MyGeotab VIN decoder can't decode the VIN. The assessment runs and a warning is raised. |
