Lithium battery pack - portable flue gas analyzers lithium battery group applications
一、Portable integrated flue gas analyzer introduction
The portable integrated flue gas analyzer adopts the international advanced technology, wide measuring range, suitable for all coal, oil and gas-fired boiler flue gas test with independent intellectual property rights NDIR NDIR electrochemical gas analysis, an instrument measuring smoke gas CO, CO2, O2, SO2, NO2, NO volume concentration and exhaust gas temperature, and English software operation interface, and can freely switch with automatic data storage, query, delete, export and other functions, the structure is simple and lightweight design , rechargeable lithium battery-powered, easy to carry.二、Lithium battery pack requires comprehensive portable flue gas analyzer
Portable flue gas analyzers operating current of approximately 1.5-2A, to work for 3 hours, and requires more than 800 times the cycle life requirements, therefore I am using imported Sanyo batteries combination of the battery with a high energy than light quality advantages of small volume, high cycle life, high safety, high voltage consistency.

三、Power Solution
The portable integrated flue gas analyzer lithium battery protection function
Chip: (import Sanyo 18650 lithium-ion batteries)
1, the protective plate (PCM): rechargeable lithium battery pack protection circuit design, smart electricity due to the chemical properties of the lithium battery, overcharge, over discharge, short circuit, overcurrent protection function. In order to avoid any risk of combustion, explosion, etc..
2, protection IC (Protection IC): the main protection function chip design, the batteries overcharge, over-discharge, over-current, short circuit and functional online constantly monitor the batteries in a safe, stable and efficient range.
3, the temperature switch: mainly designed for temperature protection function. When the battery itself, the temperature reaches the range of 70 ± 5 ℃ result of other anomalies, the temperature switching operation temperature protection
4,18650 lithium-ion batteries / 18650/2500mAh/3.7V Li-ion cell (SANYO).
5, FETs (MOSFETs): MOSFET tube, to switch from the role in the protection circuit, always so that the voltage across the load will not be increased nor decreased, to ensure the voltage stabilization.
