Technical field
The present invention relates to a kind of electric car combustion experiment platform and experimental methods, are used for electric car and electric car
The fire safety evaluating of the systems such as interior battery, motor, high-voltage wiring harness is tested.
Background technique
World today's energy shortages and environmental pollution are got worse, and various countries are it is well recognized that energy-saving and emission-reduction are future automobiles
The main direction of technology development.Electric car has the distinguishing features such as efficient, energy conservation, low noise, zero-emission, will become 21 century
Cleaning, efficient and sustainable development the vehicles.
Kuomintang-Communist sale of electricity electrical automobile 370,000 in 2015, new-energy automobile sales volume in 2016 reach 50.7 ten thousand, sales volume two
Secondary global first, electric car in 2017, new-energy automobile sales volume have had reached 770,000, meanwhile, ownership has surpassed
1,600,000 have been crossed, the half in the world is accounted for.According to the new-energy automobile development plan that country puts into effect, the year two thousand twenty, pure electric automobile are arrived
With plug-in hybrid-power automobile production capacity up to 2,000,000, adding up volume of production and marketing is more than 5,000,000.The electric car in the U.S. is cut
It is 52.8 ten thousand to ownership in October, 2016, wherein pure electric automobile about 280,000, plug-in hybrid are 24.8 ten thousand.December
Part U.S. electric car registration amount has reached 24635, and annual accumulative sales volume in 2016 is close to 160,000, compared with 2015
Increase 37%.With the increase of electric car ownership, electric car fire was also continuously emerged, from Shenzhen BYD in 2012
" 5.26 " fire incident was to Beijing three inner village Yangze river and Huai river IEV5 electric car " 6.26 " fire of southern exposure in 2016, and electric car fire is not
Disconnected to be pushed over public opinion forward position, fire brigade is at the fire fighting and rescue of electric car and fire investigation field and explores rank
