After all, for the current 'nothing' Universe Group, when developing new energy vehicles, if there is no battery technology, it is obviously not possible.

The usual measures are naturally for the early research and development of new energy vehicles.

The reaction given by the Tianneng Group was agreed.

First, because Zhang Datian was too enthusiastic about the automobile business and could not bear to break off the relationship with each other, and in addition, the two sides still had an electric factory to invest in and build, so the relationship was too stiff and not good.

It's just that for the battery technology provided for new energy vehicles in the early stage, Tianneng Group has left an eye on it, and in the battery technology supplied, the battery technical parameters used are several years ago, and the latest technical means are retained.

These do not have much impact on the early stage of research and development.

After all, the work done by the R&D team in the early stage is nothing more than the construction of the electronic system of the whole vehicle and the design of related circuits.

And with the current R&D direction, because it is the warm-up of new business, the new energy vehicles developed are mainly 'electric power', and as for the 'hybrid' models, they will not be involved for the time being.

As a 'pure electric' power mode, the biggest problem at present is the battery.

Although Tianneng Group has given certain technical support, it is a little caught off guard in the technical data of several batteries given.

First of all, the lead-acid battery provided to the R&D team has a quality of more than 1,000 catties of battery packs alone.

The technology of lead-acid battery has a history of hundreds of years, although the cost of the battery pack given by Tianneng Group is relatively low, but the mass of more than half a ton makes it difficult for the R&D team to design and put it on the car.

Moreover, the energy content of lead-acid batteries per unit is too low, and if the 'endurance' ability of the R&D model is considered, if it is to ensure that it reaches the current average level of more than 200 kilometers, I am afraid that the number of photocells used together will exceed the weight of one ton.

In the other battery technology provided, there is some sincerity, and the mature technology of nickel-metal hydride batteries has been taken out.

NiMH batteries also have a good reputation in the industry.

After all, in the past, nickel-metal hydride batteries were widely used for their long life, high energy density and high memory.

But in the same way, having so many points at the same time and the high cost is naturally the characteristic of nickel-metal hydride batteries.

The most important thing is that in new energy vehicles, as an existence that is more important than the 'heart', the long-term and repeated use of the electric power source must also meet the requirements.

The nickel-metal hydride battery obviously does not have very good durability.

The previous cyclic charging energy test data of nickel-metal hydride batteries show that the battery of this technology generally does not have a big gap in the secondary charging loss degree when it is about 500 to 600 times of cycle charging, and generally decreases by about 0.1% each time.

However, judging from the secondary charge of more than 600 times, the energy loss will appear relatively large.

According to the nickel-metal hydride battery contained in the normal car model, if the theoretical value of the battery can drive 350 kilometers in theory, the new energy vehicle using the nickel-metal hydride battery as the power source will enter the 'rapid decay period' after driving more than 20,000 kilometers at most.

At this time, cars equipped with nickel-metal hydride batteries are faced with two choices, one is to replace the battery, or simply abandon the car.

At present, in the new energy vehicle market in Huaxia, there are several foreign-funded car companies that use this kind of battery in the new energy vehicles launched.

Although these car manufacturers advertise the 'endurance' ability of more than 350 kilometers at a time, the total mileage of more than 80,000 kilometers, etc., when these car manufacturers launch new cars, these values are far from being reached.

And in the atmosphere of the current government in China vigorously promoting "new energy vehicles", this kind of model has been tried and tested repeatedly.

As for the lithium battery technology that the R&D team wants most, Tianneng Group does not provide it.

After all, lithium-ion batteries, as a new type of high-voltage, high-energy-density rechargeable batteries, have the characteristics of light weight and large energy storage.

It's just that at present, among the domestic battery companies in Huaxia, there are few lithium battery technologies with completely independent intellectual property rights.

Tianneng Group was naturally one of them, but it did not provide the corresponding technology to the Universe Group.

After a period of research and development, there is no mature lithium battery technology as a power supply, and it is a waste of time to develop a few 'broken batteries' in hand.

Fang Xiaoguang, the leader of the R&D team, reflected this problem to Lao Chang.

In desperation, he just began to contact Zhang Datian frequently to see if he could loosen his tone and meet the current preliminary research and development work.

But I don't want Zhang Datian to be very resolute, and has said several times that as long as the final cooperation contract can be signed with the Universe Group on the cooperation of new energy vehicles, Tianneng Group will take out all the most advanced battery technology without hesitation.

But when it comes to signing a contract, I often can't make up my mind.

Moreover, the reason why the Universe Group has not signed a formal cooperation treaty with the Tianneng Group is that Lao Chang naturally knows the key.

On the question of who will take the initiative, he knows Zhao Tian's consistent attitude and way, so naturally he will not agree.

Now Tianneng Group, relying on its own battery technology advantages, frequently releases signals to take the initiative, and it is difficult for the two parties to compromise for a while.

After all, battery technology is an important part of new energy vehicles, in the current form of the Universe Group, although all components can be purchased to create a car, but with one more core technology in hand, the stability of the performance of the vehicle is still more guaranteed.

What's more, Zhang Datian personally promised that if their cooperation with the Universe Group was finally reached, Tianneng Group would contribute three billion yuan as the cost of new energy vehicle business.

Although Lao Chang has already spent 2 billion yuan from the group on investment and construction costs, this 'huge investment', when he really started the business, he knew that the consumption of new energy vehicle research and development is even more afraid of traditional cars.

Now only some laboratories have been temporarily built for the R&D team, and the funds consumed have exceeded 500 million. If it was time to wait for the car, Lao Chang would have no concept in his heart. ()
