Case Study | Battery Pack Air Tightness Testing Project

Industries Served
Automotive manufacturers, service centers, and regional after-sales facilities.

Maintenance Challenges

1. Limited automation in traditional methods – Conventional leak testing often uses manual air pumps to pressurize the battery pack, which cannot provide accurate leakage measurement or generate detailed assessment reports.

2. Poor stability under varying conditions – Traditional devices are highly affected by temperature changes and environmental factors, making it difficult to maintain consistent testing accuracy.

Equipment Used

Model: FQ-80H Battery Pack Air Tightness Tester

Project Achievements

1. Integrated high- and low-pressure testing
   Equipped to verify the sealing performance of both liquid cooling plates and internal battery pack cavities, enabling one device to perform multiple testing functions with high accuracy and stable environmental control.

2. Intuitive visual display
   Dynamic graphical interfaces clearly present each testing stage, allowing operators to see the complete leak detection process at a glance.

3. Real-time comparative analysis
   Multiple test results can be compared instantly to identify leakage variations. The system delivers high repeatability and stability while minimizing the impact of external factors.

4. Customizable functions

• Supports remote OTA updates and user-specific interface customization.

• IoT-ready with cloud-based data management and platform integration for centralized monitoring.
