What concrete information can you get from this page?
Verified application example: Europe · J12 / third-generation e-POWER update reference · Qashqai e-POWER · e-POWER generator engine application · Electric traction drive; no conventional wheel-drive gearbox path
VERIFIED FACTModel / system fact
In Nissan e-POWER the gasoline engine generates electricity while the electric traction motor drives the wheels.
FAULT SEPARATIONWhen a symptom appears
If engine speed rises without a matching road-speed change, use energy-flow data to separate normal e-POWER generation strategy from generator/traction-motor limitation.
FIRST MEASUREMENTBefore replacing parts
Synchronize engine speed/load, generator output, pack SOC/temperature, DC bus and traction-motor torque with the freeze frame.

What is the first fault-separation step?
If engine speed rises without a matching road-speed change, use energy-flow data to separate normal e-POWER generation strategy from generator/traction-motor limitation.
What should be measured before replacing parts?
Synchronize engine speed/load, generator output, pack SOC/temperature, DC bus and traction-motor torque with the freeze frame.
Exact oil/fluid capacities, torque, pressure or pin values are shown only when verified in an OEM source for the matching model year, engine and market.

Where should diagnosis start?
Evaluate HV/12 V boundary, battery thermal management and energy flow together.
Exact OEM torque, pressure, capacity, pin or calibration values are not inferred from this normalized identity record; a verified service source is required for the exact vehicle application.

D · source-lineage identity; not OEM service evidence
Grade-D records are not OEM service procedures; they are source-lineage research rows preserving market/generation/powertrain identity. Exact torque, pinout, pressure or fitment is not inferred from this layer.
System architecture: what does this record indicate?
ICE, 12 V, HV/48 V, DC-DC, motor-generator and thermal management are separate control layers; energy flow is aligned with the fault event.
In an EV, HV battery/BMS, contactor-HVIL/isolation, inverter-motor, OBC/DC-DC, 12 V and cooling circuits are separate evidence branches.
Freeze-frame and live-data package
Freeze frame: first/last fault time, RPM, load, vehicle speed, system voltage, core temperatures and companion DTCs.
Electrified layer: SOC/SOH where available, cell delta, pack temperatures, HVIL/isolation, contactor permission, DC-DC output and 12 V voltage.
Measurement sequence
1) Match vehicle/generation/market/powertrain/driveline identity to the source record; family name alone is not fitment evidence.
2) Preserve freeze frame and companion DTCs before clearing; make the first-fault condition reproducible.
3) Verify power/ground and network communication under load; do not decide from key-on static measurement alone.
6) After repair, recreate the same load/temperature and verify DTC state, live-data deviation and user symptom together.
Root-cause discrimination matrix
For READY/charging faults, separate 12 V supply from the HV permission chain first; low 12 V can mimic contactor/HVIL/isolation faults.
For battery performance, use cell delta, temperature spread and voltage deviation under load/charge instead of one SoH percentage alone.
OEM EVIDENCE DOSSIER
Verified technical facts and application boundary
In Nissan e-POWER the gasoline engine generates electricity while the electric traction motor drives the wheels.[S1]
Nissan announced third-generation e-POWER technology as a production application for the European Qashqai.[S1][S2]
Engine speed is therefore not mechanically coupled to road speed like a conventional transmission, so diagnosis must follow energy flow.[S2]
Verified application matches
The matches below are published only within the stated market, model-year and evidence scope. Fitment is not extrapolated to uncited variants.
Market: Europe
Model year: J12 / third-generation e-POWER update reference
Model: Qashqai e-POWER
Engine: e-POWER generator engine application
Transmission: Electric traction drive; no conventional wheel-drive gearbox path
In e-POWER architecture, where the combustion engine does not directly drive the wheels mechanically, monitor engine-generator energy production separately from traction-motor torque.
On e-4ORCE applications additionally correlate front/rear motor torque, wheel speeds and stability-control intervention.
DTC / SPN-FMI / symptom discrimination map
If engine speed rises without a matching road-speed change, use energy-flow data to separate normal e-POWER generation strategy from generator/traction-motor limitation.
For power limitation compare engine-generator output, battery SOC/temperature and traction-motor torque limit in the same capture.
For e-4ORCE traction complaints correlate front/rear motor torque and wheel speeds with stability-control intervention.
Measurement and diagnostic strategy
Synchronize engine speed/load, generator output, pack SOC/temperature, DC bus and traction-motor torque with the freeze frame.
For power limitation separate mechanical engine measurements from generation/traction electrical data; do not use catalogue system output as a service threshold.
After repair record energy flow again at comparable SOC and road load; on e-4ORCE verify front/rear torque balance.
Exact pinouts, torque values, pressure thresholds or service limits are published only when explicitly verified by the applicable OEM service source.
