leafFinish a drive and you may see three different energy totals. They are not competing estimates of one thing. Energy drawn, regenerated and net answer related questions about what passed into and out of the battery during the journey. Keeping them separate makes the drive easier to understand.
The three totals
| Total | Meaning |
|---|---|
| Drawn / used for driving | Energy taken from the battery over the recorded drive. |
| Regenerated | Energy returned to the battery in recorded recovery periods. |
| Net | Drawn minus regenerated. |
An illustrative drive that draws 8.0 kWh and returns 1.5 kWh has net battery use of 6.5 kWh. The 1.5 kWh is not an extra reward to subtract again when calculating the cost; it is already accounted for in the net figure.
Why the power chart goes below zero
In Leaf Pro’s journey charts, positive pack power represents draw and negative power represents regeneration. A zero line helps distinguish the two. Selecting a stretch of the chart integrates the recorded power over time, separating the signs when the trace crosses zero.
Power in kW describes a rate. Energy in kWh describes an amount accumulated over time. A short sharp negative spike can return less energy than a modest negative level held for longer. Compare the integrated energy, not only the highest point.
Why more regeneration is not always better
A route with repeated braking can show more recovered energy than a smooth route while still consuming more energy overall. Recovery does not make the original acceleration free. The useful comparison is net consumption for a comparable journey, along with traffic, speed and route conditions.
A downhill segment may return energy, but a return trip has its own climb. Keep route direction in mind when comparing two drives. Similar endpoints alone do not make their elevation profiles equivalent.
What the app measures
The recorder uses vehicle readings delivered through the adapter. Its estimates depend on sample timing and completeness. Very short events can be poorly represented if the adapter is slow or data is missing. The app cannot recover an unrecorded braking event by drawing a smooth chart between distant samples.
The energy is on the vehicle side. Replacing net battery energy from the wall still involves charging losses. See the charging-cost calculation before comparing it directly with an electricity bill.
Use the figures to compare your own driving
Choose saved journeys with similar routes, traffic and conditions. Look at net Wh/km and total distance before deciding which was more efficient. Leaf Pro’s overall consumption weights energy by distance, rather than giving a tiny trip the same importance as a long one.
There is no need to change braking behaviour just to chase a number. Drive safely, preserve visibility and stopping distance, and use the recorded result to understand the route afterward. The best score is not worth an unsafe manoeuvre.
Share the right story
The Leaf Pro share card places drawn, regenerated and net energy together in the order they add up. That makes the result easier to explain. It deliberately omits location, VIN and battery health, while a full CSV contains much more detail. Review the export you choose before posting.
