P2EB5 reports that the input of the inductive charger receives too little voltage during power transfer. That input is the AC the vehicle coil collects from the ground pad across the air gap, so the level depends on alignment, gap and the power sent by the ground side. For its reference coil SAE J2954 allows vertical gaps of up to about 250 mm and a sideways offset of up to 100 mm. In the patent US10826565 of Momentum Dynamics, now InductEV, the vehicle side keeps reporting its voltage and current to the ground unit, which drops the charging signal when a fault is flagged. No manufacturer documents P2EB5 publicly. Low readings come from a poor parking position, an object between the pads, a weak ground unit or a faulty sense circuit. Charging slows or stops; cable charging is unaffected.

Likely causes

Vehicle not parked accurately over the ground pad
Object or ice between ground pad and vehicle coil
Ground unit delivering too little power
Faulty input voltage measurement in the charger

Symptoms

  • Inductive charging slow or interrupted
  • Charging fault message
