Thermal Shock Test on EV Battery Modules

Industry: Automotive

Location: Hungary – Germany

Sector Affiliation: OEM Tier 1 Supplier

Product: EV Battery Modules

The Challenge

A leading EV battery cell and module manufacturer needed to perform thermal shock tests on 15 battery modules within a tight time frame and strict specification.

Key challenges included:

• No single laboratory had enough chambers to test all 15 modules simultaneously.
• Due to the weight of the modules,the solution required multiple laboratories operating in parallel.
• The test specification demanded rapid transfer time between zones: from +70°C to -40°C (and back) within 30minutes.
• The core temperature of the modules—not just chamber temperature—was the decisive factor.
• Lacking the necessary capacity,the manufacturer’s Hungarian plant turned to KÖR to deliver a solution.

The Solution

Through our laboratory network, we at KÖR identified and coordinated three laboratories with the right capabilities and sufficient chamber availability.

• Parallel testing: We secured 6chambers across 3 labs, enabling simultaneous testing of all 15 modules.
• Precise monitoring: We implementedPT100 sensors to track module temperature during the test.
• High-frequency data recording:Temperature data of both chambers and modules was logged every second, fully meeting customer requirements.
• Synchronized execution: All laboratories were aligned to ensure identical start and end times.

Key Capabilities Delivered

• Multi-laboratory coordination to meet strict specifications.
• Synchronization of tests across different labs.
• Real-time monitoring and detailed temperature recording.
• Reliable test execution within the customer’s time frame.

Client Benefits

• Single provider solution: We at KÖR managed the entire process, simplifying service delivery.
• Seamless coordination: We synchronized three laboratories to function as one integrated system.
• Administrative relief: KÖR handled service-related coordination and reporting.
• Time savings: Parallel testing shortened validation timelines.
• Transparent communication:Proactive updates from KÖR and the laboratories.

Why It Matters

By combining technical expertise with strong laboratory partnerships, KÖR ensured the successful execution of highly complex thermal shock tests under challenging conditions—helping the client validate their battery modules quickly, accurately, and in compliance with all specifications.
