Chapter 322

In fact, there has always been a Refutation in the new energy vehicle industry - new energy vehicle environmental protection.

However, as long as we carefully analyze the raw materials and energy composition of new energy vehicles, we can know whether new energy vehicles are environmentally friendly. In fact, we have to make a question mark.

The first is the battery of new energy vehicles.

Tesla uses ternary lithium batteries. The so-called ternary lithium battery is ternary polymer lithium battery.

The cathode material of the battery is a lithium battery using lithium nickel cobalt manganate (Li (NiCoMn) O2) or ternary cathode material of lithium nickel cobalt aluminate. The ternary composite cathode material takes nickel salt, cobalt salt and manganese salt as raw materials.

In addition to the ternary lithium battery, bidi automobile also uses lithium iron phosphate battery. The lithium iron phosphate battery is the positive electrode composed of LiFePO4 material with olivine structure, which is connected with the positive electrode of the battery by aluminum foil. The negative electrode of the battery composed of carbon (graphite) is connected with the negative electrode of the battery by copper foil.

Whether it is ternary lithium battery or lithium iron phosphate battery, it is certain that there is pollution in the production process of the battery by looking at the materials used.

Although this kind of pollution is much smaller than the previous lead-acid battery, it is not completely 0 polluted.

In addition, it is the power source just mentioned.

72.4% of Xia's electricity is thermal power, that is, electricity generated by coal.

So the question is, do you use the engine to burn oil directly to reduce the pollution, or do you burn coal and then input electricity into your city to reduce the emission of charging?

The emissions from direct energy utilization must be smaller than those from indirect energy utilization.

At present, the emission standard of fuel engine in China is certainly less than that of coal after combustion in power stations.

Therefore, when you buy a new energy vehicle, the sales consultant will only say that you have zero emission during driving, and will never tell you that the electricity you charge is actually polluted, and your battery is actually polluted during production and destruction.

So why do we have to develop new energy vehicles?

Because in the field of fuel vehicles, Xiaguo's enterprises can't do Dongyang and Oumi's enterprises at all.

Toyota sells nearly 10 million cars a year, which is less than the sales of all domestic car companies in Xiaguo.

"We should actively embrace new energy, but it depends on what kind of new energy it is." Zhou Xiao said, "high consistency energy liquid is injected into the microbial battery to make the microbial battery 'move'. This is new energy!"

Zhang Zhidong fully agreed with Zhou Xiao and led the experimental team to study how to make small biological batteries form a combined battery, and then arrange small input pipes on each biological battery. When the system tests that the battery is about to run out of power, it will use a pressurized electric pump to inject the thick energy liquid from the energy liquid tank into each battery.

In the design of new energy vehicles, Zhang Zhiyang attaches great importance to the vehicle's endurance.

Zhang Zhiyang hated the endurance of new energy vehicles on the market.

The endurance of Tesla m3 is 660 km. In fact, it can only run 550 km when considering traffic jams, air conditioning, etc.

With the increase of service life, it may only run three or four hundred kilometers in the next five or six years.

The standard endurance version of Tesla m3 is even more pitiful, with a endurance of only more than 400 kilometers.

It's OK to run in the city, but what if you travel?

A small self driving tour may be four or five hundred kilometers one way and 800 to 1000 kilometers round trip.

Of course, if your electric car is expensive and can be charged quickly, you can charge at the charging pile along the way. Even fast charging takes more than four hours.

If new energy vehicles become popular, you may have to queue up to recharge.

If you drive to a mountainous area, plateau or sparsely populated place, you will be embarrassed. There is no charging pile or fast charging pile. You need to spend seven or eight hours to charge.

Charging is inconvenient and slow, which is the disadvantage of many new energy vehicles.

Zhang Zhiyang is determined to develop new energy vehicles with super endurance and super convenient energy supplement.

In Le County, Hainan Province, the energy plant improved the high-density energy block for new energy vehicles and developed the high-density energy block into a high consistency energy liquid.

The liquid can be poured into each battery under the action of an electric pump.

The modified car based on Nanma 8s, with motor and microbial battery pack, belongs to a relatively heavy urban SUV, which consumes 13 kwh per 100 km.

The calorific value of high-density energy block is 900 kcal per 100g, while the high-density energy liquid is 850 kcal per 100g.

S8 if you want to run a thousand kilometers, you need 130 degrees of electricity. According to the 70% electrical energy conversion mechanical energy efficiency of the motor assembly and 85% energy conversion rate of the colony, you need (130 divided by 0.7 divided by 0.85) 218.5 degrees of energy, which is equal to 187918.74 kcal of energy. It takes (187918.74 divided by 850 multiplied by 100) 22108g (22.1kg) to convert it into a high concentration of energy solution.

(Note: the calorific value of gasoline is higher than that of high concentration energy liquid, but the efficiency of fuel automobile engine is mostly lower than 40%)

The density of high concentration energy liquid is higher than that of water, so the volume occupied under the same mass is smaller. The "fuel tank" capacity of 22.1kg energy liquid is far less than 22L. If the fuel tank of ordinary cars is configured with 40L, the actual driving mileage of new energy vehicles will reach 1800km.

1800 kilometers!

What is this concept? It means that self driving tour can go from Shanchuan province to Shanghai stock market!

This is the data that the automobile industry has never had!

This is due to the ultra-high energy conversion rate of ionizing bacteria and the fact that the conversion rate of motor is much higher than that of fuel vehicles.

When the lab gets this data! Zhang Zhiyang knows that if the origin group wants to produce new energy vehicles, it will surely win Tesla!

In the past, why couldn't Xia's new energy vehicle enterprises defeat Tesla?

There are many reasons.

Most of them are behind Tesla in terms of endurance. Only bidi automobile and Tesla are equal.

Tesla is a little better than fast charging.

It's a little better than Di to speed up 100 meters, but it doesn't have much practical significance for users.

Spell to the end, spell what?

Only the interior!

Technology is not good. We are better than you in making interior decoration without scientific and technological content!?

Therefore, many of the summer's propaganda will make complaints about the garbage in Tesla's interior. It's a toy car, and the interior decoration of a certain car is so good!

This is the era of voting with your feet. If Tesla is really a toy car, why did the sales of electric cars end up in a few streets of Xiaguo?

When one car and another don't dare to fight for the motor and battery, but just fight for the interior, then he has lost.

If the electric vehicle made by the origin group is at the same price or even higher.

The electric car of the origin group can run 1800 kilometers and add energy liquid in seconds.

Tesla's electric car can only run 600 kilometers and charge fast for 5 hours.

What will consumers buy?
