AutoBeta(AutoBeta.net)11/15 Report--

Today, the Weima product manager introduced the Weima battery thermal management V2.0 system, which will be released at the Guangzhou Auto Show. It is understood that the thermal management system is different from traditional car companies in that it provides heat through external diesel internal combustion engines to keep batteries and in-car air-conditioning systems warm. Battery thermal management V2.0 will be 1.0 version of the difference lies in the improvement of diesel heating technology auxiliary system, diesel fuel tank upgraded from 6L to 10L, a supplement of diesel fuel can stand by for about 20 days.

Generally speaking, in order to solve the problem of battery heating, Weima car heats the battery by introducing diesel internal combustion engine, and the diesel heater and the electric heating of the car body coexist. In addition, the electric vehicle is extremely vulnerable to external temperature in winter, resulting in a great reduction in the battery life of the electric vehicle. Therefore, in order to solve this problem, the battery management system will heat the interior environment of the car and prevent the owner from using battery heating, resulting in shorter mileage.

As we all know, electric cars are extremely vulnerable in winter, especially in terms of much less electricity than usual, that is to say, the battery life of electric vehicles will be reduced, coupled with the low temperature, if the owners turn on air conditioning and heating, the battery life will be reduced by 20-30%. In this case, the battery life of 500km electric vehicles will only be about 300km. In addition, due to the low temperature in winter, the battery takes longer to preheat, resulting in longer charging time, which greatly limits the travel of car owners and is the reason why many consumers are reluctant to spend money on electric cars.

At present, most electric vehicle brands in the market have their own battery thermal management systems, but most of them heat the battery through the battery, and so is the heating in the car. but this situation greatly reduces the battery life of electric vehicles.

At present, Weima battery thermal management system 2.0 has been carried on the Weima EX5 520 model, and the Weima EX6, which will be unveiled in Guangzhou Auto Show, will also be installed.

For Weima car this wave of operation, netizens expressed different views on this.

Netizen A: you said that you drive a pure electric brand green car to the gas station to fill up with diesel. Will people who don't understand think you are a fool?

Netizen B: you are burning diesel, and the relevant departments are about to talk to you. Has the car been emitted to the sixth grade of the country?

Netizen C: if the fuel tank is a little bigger, we don't need electricity! Driving an electric dad and running to a gas station? If the electric dad catches fire, it can be even more spectacular.

Netizen D: considering that diesel is black, it is not too much for me to call cool techs.

However, the main reason that affects consumers' purchase of electric cars is its quality. For this emerging product, consumers have given it a good-sounding name-"Electric Dad". As the name implies, it is necessary to buy an electric car to supply it, not to make it "angry". Once it has a "temper", it is itself who will suffer.

The quality of electric vehicles is worrying. This year, the phenomenon of spontaneous combustion of electric vehicles has occurred many times, including brands such as Xilai, Tesla, Weima and so on, resulting in consumers' concerns about the quality of new energy vehicles. It has also had a certain impact on the sales of electric vehicles.

Of course, it can not be denied that electric vehicles have certain advantages for fuel vehicles, after all, as the future development trend, it still has a great impact on the development of society.

However, at present, electric vehicles are in the early stage of development, and there are many problems in quality, power and even basic charging piles, which lead to consumers' resistance to this new thing. In addition, many car companies can not focus on electric vehicles, developed models either for state subsidies, or for double points, the models put on the market are rarely difficult to meet the needs of consumers.

After the decline of new energy vehicle subsidies, the sales of new energy vehicles have been greatly affected, but to a certain extent, car companies have been forced to increase their research on electric vehicles to improve their competitiveness.
