22.4 Jeep – 4xe PHEV sistemi

Research frame

This is a research heading from the source atlas. The heading alone is not OEM service data or a failure-rate claim; model/generation/market identity, official campaigns and measurement evidence remain separate.

Which systems should be separated?

• ICE, HV/48 V, 12 V, DC-DC, motor-generator, regeneration and thermal management are layers of one energy chain.
• HV battery, BMS, isolation, inverter, OBC/DC-DC, 12 V and thermal management are separate evidence chains.

Evidence collection sequence

1. Compare SoC, cell deviation, DC-DC output, motor torque request, regeneration and ICE engagement conditions in one capture.
2. During READY/charging, monitor pack temperatures, cell delta, isolation, 12 V and charging-power curve together.

Risk of false generalization

• Displayed range or one SoH value alone does not prove battery health.
