P0D24 Battery Charger A Temperature Too High

P0D24 is stored when the on-board charger reports an internal temperature above its permitted limit. Chargers protect themselves by reducing power or stopping, so the driver typically notices slow or interrupted AC charging. Kia lists P0D2498, failure type 98 for over-temperature, among the codes of the integrated charging control unit (ICCU) in bulletin 298 for the 2023 Niro EV: poor or no charging on level 1 or level 2 while DC fast charging still works, sometimes with MIL and warning messages; after checking the 12 V battery and other conditions, the ICCU is replaced. CARB requires plug-in hybrids to detect charger faults that prevent or slow charging. Besides an internal defect, a weak cooling path, low coolant or a blocked air flow can drive the temperature up. Cooling system performance is P0D8F.

Likely causes

Internal defect in the charger or charging control unit (Kia ICCU replacement)
Low coolant, failed pump or blocked air flow on the charger cooling path
Charger temperature sensor reading too high

Symptoms

  • AC charging slow, interrupted or impossible while DC fast charging works
  • Warning message for the electric system, sometimes MIL
