China Automobile Association data show that China's new energy vehicles continue to explode growth,2022Annual production and sales completed separately705.8million and688.710,000 vehicles, up year-on-year respectively96.9%and93.4%, continuously8Ranked first in the world, and the market share increased25.6%higher than the previous year.121percentage points, gradually entering a period of full market-oriented expansion, ushering in a new stage of development and growth. Sales of new energy vehicles account for total sales of new vehicles.25.6%Completed three years in advance.2025Annual planning objectives. This shows that the development prospects of China's new energy vehicles are quite good.

However, these new energy vehicles are dominated by lithium batteries, which are basically used as energy storage devices. As we all know, lithium is a very active element. This characteristic makes lithium batteries thermally out of control in some cases, such as thermal shock, electrical shock, short circuit, collision, etc., which is likely to develop into a fire and explosion situation. If the drivers and passengers cannot find and evacuate in time, it is likely to cause casualties.

Lithium battery thermal runaway will release a large amount of gas, different types of lithium-containing cathode material thermal runaway release of gas is very similar, the most important gases areH2、CO、CO2、CH4Wait.

Under normal circumstances, the content of these gases in the air is notCO2The outside is very low, so our customers pass the test.H2、CO、CH4The concentration of changes to determine whether the battery thermal runaway, there is an exception in a timely manner to alert personnel to evacuate, reduce losses.

In hereTo recommend a hydrogen sensorTGS2616-C00，TGS2616-00It's JapanFIGAROResearch and development of semiconductor principle sensors,Fast response, low power consumption, small size，TGS2616-C00It contains a newly developed sensitive element, which is very little affected by interference gases such as alcohol, and has a high selectivity to hydrogen. Ideal for detecting changes in hydrogen concentration.

At the same time,TGS2616-C00The application circuit is also very simple.

Provide a stable heating voltage to the sensor, connect a fixed resistor voltage division in series, and sample the fixed resistor voltage division.

The following isTGS2616-C00The basic parameters:

      Detection range:10-3000ppm

      Circuit voltage:5.0±0.2V

      Heating voltage:5.0±0.2V

      Heater power consumption:280mW
