Medical Battery Pack solution for Flaw detector standby

1. About Medical Flaw Detector Standby

The flaw detector is a portable industrial non-destructive testing instrument that can detect, locate, evaluate and diagnose various defects (welds, cracks, inclusions, folds, pores, blisters, etc.) inside the workpiece quickly, easily, without damage and accurately. It can be used in both laboratories and engineering sites. The instrument can be widely used in the fields of manufacturing, steel metallurgy, metal processing industry, chemical industry, etc., which require defect detection and quality control. It is also widely used in in-service safety inspection in the fields of aerospace, railway transportation, boiler and pressure vessel. Life assessment, which is a must for the non-destructive testing industry. Portable flaw detectors have become an important tool for on-site testing in modern social construction sites, and providing efficient, portable, lightweight, and adequate backup power solutions for portable flaw detectors is an important guarantee for testers to perform long-term field work. The 18650 lithium battery pack has become the first choice for backup power solutions for such high-tech test equipment due to its unique advantages.

2. About Medical Flaw Detector Standby Lithium ion Battery Requirements

Due to the high voltage and long working time of the flaw detector, the quality of the equipment itself and the continuous stability of the power supply are particularly critical, which requires that the power supply must be realized by multiple series and combination of large-capacity single-cell lithium batteries; During the work process, a large amount of valuable data needs to be saved continuously. Therefore, an accurate battery power display and alarm system must be provided to prompt the user to save the data in time to improve the effectiveness of the work. The standby lithium battery solution of the flaw detector adopts an intelligent chip, and the host continuously reads the power and related important data in the smart chip through the I2C communication mode, and monitors the battery from time to time to prompt the user to perform related operations reasonably and timely. The battery integrated in our solution has the advantages of high energy ratio, light weight, small volume, high cycle life, high safety, high voltage and good consistency. The lithium battery pack design has an output overcurrent protection value of 12A and continuous working current. 7A, the charging capacity is 5200mAh, which fully meets the power demand of the instrument.

3. About CTECHI Make Battery Pack Solution of Medical Flaw Detector Standby

A. Smart Fuel Gauge Protection Board (PCM): The SBS intelligent battery management system uses the advanced power calculation principle to accurately calculate the battery power from time to time, and reports the battery power information to the host through SMBUS, and simultaneously to the rechargeable smart battery. The group performs functional protection. Due to the chemical characteristics of the lithium battery itself, it is necessary to provide protection functions such as overcharge, over discharge, short circuit, over current and over temperature to avoid the danger of burning and explosion.
B. Temperature switch: mainly designed for temperature protection function. When the temperature of the battery itself reaches 70±5°C due to other abnormal problems, the temperature switch operates to protect the temperature.
C. FET (MOSFET): MOSFET tube, which acts as a switch in the protection circuit, so that the voltage across the load will not rise or fall, ensuring voltage stability.
