Kia Niro - First generation - (DE) (2017-2022) - Service and Repair Manual / Hybrid Control System / High Voltage Battery System / High Voltage Battery System / Components And Components Location

Description

The High Voltage Battery System provides the hybrid drive motor, HSG, and electric A/C compressor
with electric energy and also reserves the electric energy generated during regeneration braking.It
consists of the battery pack assembly, BMS ECU, power relay assembly, case, control wiring, cooling
fan, and cooling ducts.

This battery is a Lithium ion Polymer Battery (LiPB) and has 96 cells (4 Cells x 24 Modules). The
voltage of each cell is 3.75V DC, so the rated voltage of this battery pack is 360V DC.
