Jaguar I-Pace Won't Charge, Charging Port Problems
When an I-Pace refuses to charge, the first question is AC against DC: DC bypasses the on-board charger, so if DC works the charger module is the suspect. If nothing charges at all, I'd look at the charge port's locking pin and the 12 V battery before anything expensive. A fault code reader that reaches the high-voltage modules saves a lot of guessing here.
How bad is it · Garage, carefully
Drivable on the charge you have — but a high-voltage warning means stop
Without charging the car is only good for the range left. High Voltage electrical fault, stop as soon as possible, or limited power with no regeneration, is not a message to drive on.
Which one applies to yours depends on your symptoms, your model year and what has already been done to it.
Likely causes, most common first
Read the check cost before the odds: a free check that rules a cause out beats a likely guess that costs money.
Auxiliary coolant pump failed
The auxiliary pump circulates coolant for the drive motors and the climate system. An internal short in it blows its fuse, and the car protects itself: very little power, no regeneration and no charging.
Limited power, no regen and no charging together, with codes such as P2600-13 and P2602-11. A new fuse blows again or changes nothing.
Codes first. The pump sits at the front left of the traction battery: with the car off, a resistance of 0 Ω from the pump's 12 V feed pin to ground means an internal short. Bench-test its 40 A relay too.
Replacing the pump brought the car back. Look for coolant that has leaked onto the harness, which has damaged wiring on another car with the same failure.
The charge port locking pin or its actuator
The car won't start a charge until the cable is locked in. If the pin doesn't drop into place, there is no charging at any level, AC or DC. A failed actuator can also trap the cable.
Stuck at Initialising on every charger, or a session that stops and won't restart anywhere; a cable that won't come out.
Lock the car with the cable in and watch the pin at the top of the connector opening. To free a cable, press unlock on the fob until you hear the actuator; with two-stage unlocking it may take several presses at a DC charger.
Worth checking first: the socket and its lock are the most frequent no-charge cause, then the harness from the socket to the battery energy module. A failed locking actuator is a dealer part.
On-board charger module (BCCM): AC fails, DC works
The BCCM handles AC charging; DC goes round it. A failed BCCM, sometimes after a mains surge, leaves the car charging only on DC, or not at all if it shorts.
Home and public AC charging fail while DC fast charging works. After a power cut on a home charger: no charging at all, a dead charge-port light, and its fuse blowing the instant it is replaced.
Spend a little range on a DC charger: if DC works, the on-board charger is the suspect. A fuse that blows straight away means a hard short in the module or its wiring — don't fit a bigger one.
Worth knowing: a replacement BCCM, even a used one from a 2020 car, which shares the part with 2019, restored AC charging. The job needs the 12 V and HV shutdown procedure and a partial coolant drain.
High-voltage isolation fault
A monitoring loop runs through every HV connection; a break or high resistance in it reads as an isolation fault and the car stops charging. That loop is powered by the battery energy control module, not the 12 V battery.
High Voltage System Fault detected, often with P0AA6-00, sometimes after DC fast charging or in hot weather. Charging failures that grow from occasional to permanent.
A scan of all modules. Confirm the H441 recall software is installed: the battery energy control version in the software screen starts with BS. Make sure no 12 V battery was changed without the right procedure.
With the HV system powered down, inspect the HV connections and the loop. Intermittent warnings that clear after a short drive can defeat a full-day diagnosis.
A cell module flagged by the recall: charge capped
The H441 recall software watches the pack's cell modules. When it finds a bad one it caps charging, typically at 72%, and the module is replaced under the recall.
OK to drive with caution, Traction Battery fault detected, and the car won't charge past 72%. It often first appears after a full charge.
Ask a dealer with an EV-certified technician to read the cell modules; many dealers don't have one, so call round.
The module is replaced free under the recall. Afterwards capacity reads low until the cells balance: give it 4 or 5 full AC charges from below 50% before judging the range.
A weak or flat 12 V battery
The car needs a healthy 12 V to wake up and run a charging session. A weak starter battery can sag under the load of DC charging, and a flat one leaves the charger with nothing to talk to.
A DC session stops minutes in with errors, for example when the starter battery falls to 12.00 V. After the pack runs empty, the charger shows no communication at all, not even Initialising.
Measure or log the 12 V batteries. If the car is dead, charge the 12 V first to wake it, then plug in.
Not settled: software updates to the 12 V-related modules didn't stop the DC cut-outs on one car. Start with the battery itself.
The order to check them in
The point of the order is money: each step either rules a cause out or makes the next one worth doing. Green is free, amber costs a little, red is the one to arrive at last.
AC against DC
Try a different charger and, if you can, a DC one. DC working with AC failing points at the on-board charger.
freeWatch the locking pin
With the cable in, lock the car and look for the pin dropping at the top of the connector opening.
freeFree a stuck cable
Press unlock on the fob until the actuator is heard; several presses if two-stage unlocking is on.
freeCheck the 12 V side
A dead car can't charge: wake it by charging the 12 V first. A weak 12 V can also cut DC sessions short.
cheapRead all the modules
A reader that reaches the HV modules: P0AA6 is isolation, P2600/P2602 the auxiliary coolant pump. Check the H441 software is on the car.

That is a hard short downstream. Never fit a higher rating; find the module or wire that's shorted.

Charger modules, HV connections and cell modules need one. Parts can take weeks, so book early.
