In addition to being conducive to subsequent mobility, there will also be many conveniences when repairing the supercharging station, so Zhou's proposal was quickly approved by Martin Eberhard.

Next, several people had a discussion on the rest of the structure of the charging station, but it did not involve very detailed parts, all of them were specific framework types, the framework was determined first, and the subsequent details would be improved by the technical staff of the project team.

"Since we are engaged in new energy vehicles, then I suggest that the form of energy used in charging stations can also be diversified, at this stage can mainly rely on the grid power supply, but can also be assisted in the use of solar charging, to minimize the dependence on the power grid, if the technology is mature, you can fully use solar charging instead of grid charging. ”

Zhou Jingming proposed again. Although the advent of solar-powered electric vehicles is still just a concept, Zhou Jingming feels that the application of solar technology in charging stations is completely feasible.

"I think it's a very good idea, not only for solar energy, but also for more forms of energy to power the charging station in the future. Alberhard said as he jotted down Zhou Jingming's proposal.

"I have a question, since the super charging station is to replace the role of the gas station, then how to solve the compatibility of the charging station, if pure electric vehicles will be fully popularized in the future, the manufacturing of electric vehicles must not know our family, then our charging station, can only charge our own cars, or as long as the payment is paid, all can be charged?" said Wang Yuanchao on the side.

Wang Yuanchao's question immediately aroused the thinking of Zhou Jingming and others, because this is a very real problem.

Although the current gas stations are divided into different operators such as PetroChina and Sinopec, any car can enter the station to refuel, but the model of refueling will be different, but what about charging stations?

Is it possible to design different charging stations for electric vehicles made by different businesses and work independently?

There are too many types of charging stations in this way, not to mention whether there is enough space to build, even if it can accommodate so many super charging stations, it is not convenient for consumers to travel.

The best result is that in the future, no matter which electric vehicle manufacturer builds a super charging station, it can be compatible with the electric vehicles produced by the rest of the manufacturers, or more simply, the super charging station is built by the state, or a special industry association is set up, and a unified specification standard is formulated, and the emergence of a separate situation is not allowed.

"This problem is not difficult, there is no international enterprise specializing in the production of pure electric vehicles, since we are the leader, then we can explore the construction standards of electric vehicle charging stations on our own, and design a compatible system that can be uniformly controlled, so that any business that enters the electric vehicle industry in the future will follow our established industry norms. ”

Martin Eberhard thought for a moment, looked at the crowd and replied.

As the formulator of industry norms, Zhou Jingming is no stranger to this kind of thing, and the 16949 system is not designed by Zhou Jingming.

"If, as Mr. Martin said, a unified industry standard for electric vehicles can be formulated, then it will be an absolute guarantee for our future leadership in the electric vehicle market!" Zhou Jingming nodded, and then continued,

"In this way, regarding the industry standard of electric vehicles, Mr. Martin and the relevant personnel will first formulate a first draft, and then I will take this document and find the competent authorities, at least in China, to set the industry standards for electric vehicles. ”

It's not just about industry norms, if you really start building charging stations later, the power grid system, municipal departments, these units, Zhou Jingming have to do it in advance, and when you go to Yanjing, Zhou Jingming will do these things together.

Although there are no substantive results in this discussion, these framework contents will reduce many detours for the subsequent development of electric vehicles, which is very necessary in Zhou Jingming's view.

After coming out of Wang Yuanchao's office, Zhou Jingming was still discussing the development of electric vehicles with Kocone.

"Do you two have any preliminary ideas about the battery panels used in electric vehicles?" Zhou Jingming asked as he walked.

"The battery is one of the most critical components of an electric vehicle, and I don't really have an idea for the time being, so my idea is to use GM's EV-1 as a reference and then upgrade it. Coconi replied.

The EV-1's unsuccessful and low battery life was an important reason.

"The EV-1 uses a lead-acid battery, which has a mediocre power storage capacity, so if I had to try it, I would try it with a lithium battery. Martin Eberhard on the side followed.

"The advantage of lead-acid batteries is that the cost is low, from the perspective of power storage capacity alone, lithium batteries are naturally a better choice, but to manufacture a whole piece of such a large lithium battery, the cost will make us face an important problem, do not control the cost, no matter how high the endurance is just a decoration. Koconi retorted.

The lithium battery has a strong power storage capacity, and Coconi naturally knows it, but the main reason why the EV-1 does not use lithium batteries and chooses lead-acid batteries is that the cost of lithium batteries is too high.

A suitable balance must be found between the range and cost of an electric vehicle.

"In fact, I think that in terms of batteries, it is not necessary to use a whole large battery, but it is completely possible to connect a sufficient number of small batteries to provide power for the car, so that the cost can be controlled?" Zhou Jingming said.

"What the chairman means is that there is no need to develop large lithium batteries for automobiles separately, and the existing small batteries, such as lithium batteries on laptops, connect thousands of these batteries and use them as the power source of electric vehicles, right?" Martin Eberhard said with some excitement when he heard this. He had also conceived such a plan, but it had never been put into practice.

"If you use this series connection, once one battery is burned, won't the entire battery board also stop working, and how can the stability be guaranteed?" Koconi continued to ask rhetorically.

Once a link in the series circuit fails, the entire circuit system will stop working, and people who have learned a little about electricity understand this truth.

However, Cocconi's question did not make Zhou Jingming feel embarrassed, "It doesn't have to be in series, I don't know much about circuits, but there must be many solutions, and if you make these batteries into the form of battery packs, you will definitely be able to find a solution, which is the problem you need to solve next." ”

Tesla's proud battery life is the use of this self-developed battery control system, the battery pack composed of more than 7,000 batteries, even if it is short-circuited, it will not catch fire, and individual battery damage will not affect the normal operation of the battery pack.

"Knowing the chairman, we will develop it according to this line of thought. Koconi scratched his head a little embarrassed, he was here to solve the problem, not to ask the problem as he had just done.
