Sealed Battery Helium and Defect Detector for Prismatic Cell

Ⅰ、Product Introduction

The equipment is used for sealing testing after welding the top cover of power batteries. Its main functions include: battery scanning, battery loading, helium inspection, cavity helium cleaning and detection, automatic retesting of defective products, battery cutting and troubleshooting, etc.

 

Ⅱ、Technical Specification

Basic parameters	Value
PPM	15PPM(customized)
Testing method	Helium detection
Applicable battery size	W140-180mm，H 85-220mm,T 20-80mm
Helium detection time	≤5S
Missed kill rate	0%
Helium injection pressure	0.05-0.15Mpa, adjustment accuracy 0.001Mpa
Minimum detectable leakage rate	1x10-12*m3/S
Sealing of cavity	Vacuum to 20pa and hold for 2 minutes before starting the test. The pressure drop within the cavity is less than 50pa within 1 minute

 

Ⅲ、Advantages

1. Data collection with high sensitivity and fast response

2. Automatically detect helium gas in the cavity, automatically clean contaminated cavities, and prevent false detections.

3. Automatic monitoring of helium pressure and concentration. When the pressure and concentration are insufficient, the system automatically replenishes helium.

4. Modular design, short changeover time, fewer parts, and low cost.
