EV Charging History report

The EV Charging History report provides a comprehensive record of your electric fleet's charging sessions, including energy added, power levels, and charging duration.

The EV Charging History page, accessible via Fuel and Energy > EV Charging History, provides a comprehensive report on your electric fleet's charging sessions. This page is the EV equivalent of the Fill-Ups Report used for fuel. This report provides information about the electric power and energy consumed when vehicles plug in to charge.

EV Charging History report questions answered

Key Questions

Answers

What happened? Where, when, for how long, and how much did EVs charge? Why do my EVs have the battery charge percentage that they have?

Answered generally by EV Charging History.

What is the EV contribution to facility load?

Sum total Energy Added by Zone.

Note:

To calculate charging costs, consider:

  • EV Charging Cost Report: Easily calculate charging costs, factoring in different energy prices in different locations. It does not factor in different prices by time of day (works well when you have a single price per location).
  • Marketplace solutions from partners that specialize in home charge reimbursement. For more information, contact your Reseller.

Report fields

Important:

Charge events are grouped differently on different tabs of the EV Charging History report.

Charge Event (Report Tab of excel report): A Charge Event is recorded from when charging starts (power > 0 W) to when it stops (power = 0 W). While a vehicle is parked, there may be multiple Charge Events. On the report tab, each row of data corresponds to a single Charge Event. This captures each time charge management software or plug sharing causes EV charging to start or stop.

Charge Session (MyGeotab UI, Summary Tab of excel report): A Charge Session is a group of Charge Events that occurred during a single vehicle stop. On the summary tab of the excel report (and in the MyGeotab UI), each row of data corresponds to a single Charge Session. This results in a more readable summary of charging behaviour.

Field

Description

Start Date

In the Report Tab of the excel report, this is the date and start time of the Charge Event. In the MyGeotab UI or Summary Tab of the excel report, this is the date and start time of the Charge Session: the start of the first charge event during a single stop.

End Date

In the Report Tab of the excel report, this is the date and end time of the Charge Event. In the MyGeotab UI or Summary Tab of the excel report, this is the date and end time of the Charge Session: the end of the last charge event during a single stop.

Odometer

The vehicle's odometer at the charging time.

Location

The street address of the charging location. When Personal Mode is applied, this will be blank.

Zones

If the location is within one or more Zone, the names of the Zones are displayed. When Personal Mode is applied, this will be blank.

Zone Types

If any Zone has one or more Type, the name of each Zone Type is displayed. When Personal Mode is applied, this will be blank.

Start Charge %

In the Report Tab of the excel report, this is the battery charge percentage remaining at the start of the Charge Event. In the MyGeotab UI or Summary Tab of the excel report, this is the battery charge percentage remaining at the start of the Charge Session: the start of the first charge event during a single stop.

End Charge %

In the Report Tab of the excel report, this is the battery charge percentage remaining at the end of the Charge Event. In the MyGeotab UI or Summary Tab of the excel report, this is the battery charge percentage remaining at the end of the Charge Session: the end of the last charge event during a single stop.

Energy Added

The total electric energy added, expressed in either kilowatt-hour (kWh) or watt hour (Wh).

Max Power

During a Charge Event or Charge Session, the power typically fluctuates. The maximum value is the best indicator of the sustained power found throughout. The maximum value is also the best indicator of the EV contribution to additional billing charges resulting from excessive power demand, and for being aware of the capacity requirements for EV charging.

Current

This is either AC (Alternating Current) or DC (Direct Current).

AC Voltage

The Alternating Current voltage.

Note:

For those in North America who want to display charging as SAE Level 1 (120 V AC), SAE Level 2 (~240 V AC), or SAE Level 3 (DC), use the Current and AC Voltage values to extend the report.

EV Charging History

The EV Charging History feature tracks charging events for the electric vehicles in your fleet.

A charging event is logged every time the system detects that charge is added to an electric vehicle. Viewing this data in sum can help you see when assets typically need to charge and how long a charge event typically lasts. It can also allow you identify cost saving opportunities for your fleet.

The EV Charging History feature shows each asset that logged a charging event during the selected time period, followed by a list of each charging event the asset logged. The following data is displayed for each charging event:

  • The zone where the charging event was logged (If the charging event took place outside of any zones, MyGeotab displays an Outside zones label)

  • The date and time the asset started and ended the charging event

  • The charge duration

  • The address where the charge event took place

  • The battery charge percentage at the beginning and end of the charging event

  • The amount of electric energy added during the charging event

  • The device associated with the asset

  • The odometer reading at the time the charging event was recorded

You can view the trip associated with each charging event by clicking the Map icon next to the zone name where the event took place.

Why does the Fuel and Energy Usage Report show different energy consumption, when compared to the EV Charging History Report?

The two reports measure different energy flows: one measures energy leaving the battery during driving, while the other measures energy entering the battery during charging.

These reports are measuring different things:

  • The Fuel and Energy Usage report measures energy that leaves the battery while the vehicle is driving or idling.
  • The EV Charging History report measures energy that enters the charging port of the vehicle while the vehicle is charging.

Because of losses in internal vehicle components, these measurements will be different.
