P2EB6 is the counterpart to P2EB5: the voltage at the input of the inductive charger is higher than its electronics accept. Too much induced voltage can stem from a ground unit sending more power than requested, a ride height that shifts the coupling, for example when the vehicle is loaded or unloaded during charging, or a control loop between both sides that has lost step. Momentum Dynamics' patent US10826565 explains why the vehicle side reports voltage, current and the gap in near real time, and how the ground unit halts transfer at once when the vehicle signals a fault. SAE J2954 sets the 85 kHz band and the power classes within which these limits work. No manufacturer documents P2EB6 publicly. The charger shuts down to protect itself and the battery; cable charging stays possible.

Likely causes

Ground unit sending more power than requested
Coupling changed by ride height or position during charging
Disturbed communication between vehicle and ground unit
Faulty input voltage measurement in the charger

Symptoms

  • Inductive charging stops shortly after starting
  • Charging fault message
