For electric vehicles
The problem of mileage reduction in low temperature environments is common
He and his team
Solved the difficulty of starting electric vehicles in winter
Problems such as short mileage
He is
The 24th Beijing Outstanding Young Engineer Pacesetter
Winner of the first prize of the China Automotive Industry Science and Technology Progress Award
Beiqi Foton new energy vehicle
Deputy Chief Engineer and Vice President of the General Institute of Engineering Research
Wei Changhe
New energy vehicles are being carried out on a large scale
Spread into our lives
It's not hard to find
Vehicles on the road
More and more new energy vehicles have emerged
And there are various models large and small
However, new energy vehicles
All need to be charged
Originally, it was a matter of energy conservation and environmental protection
But in winter
Charging suddenly became inconvenient
Winter because of the cold
Electric cars have an obvious problem
It's that the mileage is shortened and the start is slow
At room temperature
The range of a fully charged electric vehicle
it is 250 km
The mileage in winter is much lower
Range at normal temperatures
To solve these problems
Under the unremitting efforts of Wei Changhe's team
It took a year and a half
Finally, a tram with resistance to -35 ° C was developed
In cold conditions
Range of electric vehicles
it is 220 km
Although the mileage has a certain attenuation
But the goal was achieved
Conquered pure electric vehicles
The challenge of driving normally in extremely cold environments
In 2020
The country is preparing for the Beijing Winter Olympics
Again to the Wei Changhe team
Conveyed the task
Undertake during the Beijing Winter Olympics
Transport tasks for staff and participants
In order to host a green Winter Olympics
Therefore the services provided guarantee the vehicle
Basically, they are all new energy vehicles
Next, let's get to know him through the video!
