Hybrid/EV Powertrain Control Module 2

WARNING: This page is about a different variant/trim than selected.

The hybrid/EV powertrain control module 2 is located above the hybrid/EV battery sections. The module is responsible for monitoring the battery parameters via the hybrid battery interface control modules.

The hybrid/EV powertrain control module 2 is responsible for the cell balancing process. During operation, individual cells may charge or discharge at different rates. To ensure proper battery health and optimal life, these voltages are balanced, with energy from a higher voltage cell being transferred to a lower voltage cell. This keeps the voltage consistent between all the cell groups. Cell balancing is an internal process of the hybrid battery interface control module. Internal gates allow energy to flow between cells using the same circuits that are used to monitor cell voltage.
