In the context of national policy support, domestic new energy vehicles have developed rapidly in recent years, and China has become a global zui.new energy vehicleMarket, and there is still a very large space for development; at present, my country's new energy vehicles mainly include pure electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles. Among them, pure electric vehicles dominate the market,2018Annual production and sales accounted for nearly80%Therefore, we mainly take the development of pure electric vehicles as an example.

The replacement of fuel vehicles by new energy vehicles has gradually formed a trend, which is an urgent need for green, environmental protection, energy saving and sustainable development in China. The state's support for the consumption of new energy vehicles is very strong, which can be summarized as followsMoney subsidy, tax relief, license road.At the same time, the penetration rate of special parking lots and charging piles for electric vehicles is also increasing year by year. Therefore, the future of new energy vehicles is bright and the historical trend is unstoppable.

New energy electric vehicles have always been claimed to be the hope for my country's auto industry to achieve "corner overtaking". However, behind this seemingly prosperous, there are many problems. First of all, the core technology of my country's automobiles is still far behind that of European and American countries, and many parts still rely on imports. If new energy vehicles cannot break through in technology, it will be surpassed sooner or later; secondly, the manufacturing cost of new energy vehicles is high and the government Subsidies are too dependent. If there is no government subsidy, many new energy vehicle companies will lose money; in addition, the supporting facilities of new energy vehicle charging piles are not perfect, although the number of charging piles is rising every year, it is still not enough to support the development of new energy vehicles, and the distribution of charging piles is uneven, mostly concentrated in developed cities and highways; zui's important new energy technologies are emerging technologies after all, and safety issues There is still a lot of controversy, and new energy vehicle fires occur frequently.

From January 2019 to now (8In the middle of the month), according to incomplete statistics, there are at least 19 new energy vehicle fires in China, with an average of at least 2 fires a month, especially in August, with 5 spontaneous combustion incidents in less than 15 days.2019In the first half of the year, onlyWeilai AutoCarOne recalled 4803 cars with potential safety hazards. The causes of the fire included battery module design defects and other factors.

Improving safety technology requires a long process. In order to minimize casualties and losses, it is very important to detect fires in time. Therefore, we can consider installing fire detectors on the car.COgases, we can monitor in real timeCOOnce the gas exceeds the alarm threshold, start the alarm, evacuate people and start the fire, so as to win more valuable time.

Here,recommend a paragraphCOSensorTGS5141, The sensor has the advantages of small size, long life, andCOHigh sensitivity, long-term stable performance, consistentUL2034、EN50291Certification requirements and other advantages, is a good choice for fire detection alarm.
