The P0BA9 fault code refers to a circuit issue in the 23rd battery cell group of a HybridElectric Vehicle (EV) battery pack. The battery pack consists of 288 cells, grouped in parallel sets of three. There are a total of 96 cell groups connected in series, with each group rated at 3.7V.

The nominal system voltage is 355V DC. The battery cells are divided into three sections.

Section one contains 90 cells (30 cell groups) located adjacent to the cowl, batteries 67 to 96.

Section two is behind section one and consists of 72 cells (24 cell groups), batteries 43 to 66.

Section three, the transverse section, has the remaining 126 cells (42 cell groups), batteries 1 to 42. The battery energy control module monitors the voltage of the cell groups through hybridEV battery interface control modules. Voltage sense circuits are attached to each cell group, and the readings are transmitted to the battery energy control module.

The fault condition is communicated to the hybridEV powertrain control module 2 for diagnostic purposes.

In summary, the P0BA9 fault code indicates a circuit issue in the 23rd battery cell group of a HybridElectric Vehicle battery pack.
