Hyundai Wia Begins Mass Production of Thermal Management Modules for EV9 and Kona Electric Vehicles

Cooling Water Hub Module, Annual Production of Up to 210,000 Units
First Domestic Auto Parts Company
"Tested Under Harsh Conditions"
Integrated Thermal Management System Development by 2025

Hyundai Wia announced on the 16th that it has begun full-scale production of the 'Coolant Hub Module,' one of the dedicated thermal management systems for electric vehicles. This is the first time a domestic automotive parts company has produced this module. Up to 210,000 units are expected to be produced annually at Hyundai Wia's Changwon Plant 1 in Changwon, Gyeongnam. This module will be installed in the Kia EV9 and Hyundai Motor's Kona Electric.

The module developed by the company helps efficiently manage the heat of electric vehicle batteries, drive units, and electronic equipment components. The company explained that it improved efficiency by functionally integrating separate devices responsible for cooling drive components and batteries. Specifically, it integrated the reservoir tank that supplements coolant, the electric water pump, and valve functions. This allows the battery temperature to be optimally maintained while managing the heat generated from drive components such as the motor and inverter at appropriate temperatures.

To ensure the reliability of this module, a total of 53 types of evaluations were conducted at the single part, module, and vehicle levels, including thermal shock tests. Additionally, 23 types of quality verification procedures were completed before final production.

Based on the mass production of this module, Hyundai Wia plans to develop an integrated thermal management system covering motors, batteries, and interior air conditioning by 2025. As part of this effort, they are constructing a 'Thermal Management Test Building' at their research center located in Uiwang, Gyeonggi Province, aiming for completion next month.

A Hyundai Wia official stated, “We have created the Coolant Hub Module based on the technological expertise accumulated over a long time through mass production of automotive parts, especially modules. With the mass production of the Coolant Hub Module, we are making a full-scale entry into the thermal management system market for electric vehicles,” adding, “We will strive to become a company with global competitiveness in the future mobility market through continuous research and development.”
