Just for the actual measurement of the sample battery, Ye Jiayi originally did not plan to alarm Mr. Xu of Chengsheng Automobile Company, but Lao Wan's words made her heart cold for a while, it seems that for such a trivial matter, she has to go to see the great god.

Fortunately, Ye Jiayi is a caring person, not only has she kept in touch with several big leaders of Chengsheng Automobile Company over the years, but also before the cooperation with the New Materials Research Institute began, she deliberately strengthened this connection, otherwise, when she suddenly mentioned this matter, let alone the other party, even Ye Jiayi herself felt abrupt.

Dialed the phone number of Mr. Xu, the leader of Chengsheng Automobile Company, Ye Jiayi reported to herself, "Hello Mr. Xu! I am Ye Jiayi of Changda Group." ”

"Changda Group, is the Changda Auto Parts Company with which we have a parts partnership, right?" It seems that Lao Xu has an impression of Changda Group and Changda Auto Parts Company.

"Yes, Changda Auto Parts Company is a wholly-owned subsidiary of Changda Group. ”

"I think of it, Mr. Ye is not only the general manager of Changda Group, but also in charge of the business of Changda Auto Parts Company, I remember half a year ago, you came to us to do business, and we also met. ”

"Mr. Xu has a good memory, that's right, we visited customers half a year ago, and we met. ”

"Ye is always the general manager of Changda Group, wearing many hats, and he has a lot of opportunities, so call today, is there anything wrong?"

"There's something I want to ask Mr. Xu for a favor. Ye Jiayi said bluntly.

"Oh, Changda Auto Parts and Chengsheng Automobile Company are old relations, what does Mr. Ye need help with? ”

"I heard that the electric vehicle project of Chengsheng Automobile Company is progressing smoothly, but I wonder where it is now?"

"The trial production of the whole vehicle has been completed, and the next step is to prepare for road testing. "Lao Xu's grasp of the situation is similar to that of Lao Wan.

"Congratulations on the smooth progress of the project! In other words, Chengsheng Automobile's electric vehicles are not far from being listed," Ye Jiayi said.

"Hehe, I'm afraid it's not that simple, it's still too early to talk about going public until the car's powertrain is well resolved. "Lao Xu is very sober.

"Mr. Xu, doesn't Chengsheng Automobile's electric vehicle have a suitable power system yet?"

"The batteries of several companies have not worked well, and now this is the key to the success or failure of electric vehicle projects. Lao Xu said frankly.

"Mr. Xu, please help me just now, related to this problem, in the power system of the electric vehicle project, can you give us a chance?"

"Aren't you making auto parts, why do you care so much about car powertrains?"

"Isn't the battery also an auto part for electric vehicles? Ye Jiayi said.

"You're right, batteries are also auto parts, but I still don't quite understand what you mean, are you also producing high-energy batteries for electric vehicles?"

"To be precise, we are working with a research institute to develop high-energy batteries for vehicles, and we have already achieved satisfactory test results. ”

Changda Group is really powerful, high-energy batteries for vehicles are high-tech projects, and many units are doing it, but there are very few who do it well. Lao Xu said.

"We take the Institute of New Materials of the Academy of Sciences as the technical support unit, and cooperate with them to develop solid electrolyte and battery separator materials, after testing, the indicators are leading in China, close to the international advanced level, and the next step, we want to apply it in electric vehicles. Ye Jiayi said.

"That's what you've asked me to help with, right? No problem! But let me state in advance that there are now four or five battery manufacturers that we are cooperating with, and I can promise your products to join the ranks of the test, but whether they can win in the end depends entirely on the performance of the battery. ”

"As long as we can make Changda Group's products compete with other enterprises, we are very grateful! Mr. Xu, any product of Changda Group is to participate in market competition with high cost performance and high-quality after-sales service, so to speak, in the market, Changda Group does not have those small actions that are not seen. In this regard, Ye Jiayi has always been very confident.

"Yes, it is precisely because of this that Chengsheng Automobile Company has become the largest user of Changda auto parts. Lao Xu agreed.

"If Mr. Xu agrees that the battery of Changda Group will join the trial ranks, please say hello to the relevant departments, and we will send the samples over after a while. ”

"No problem, let me know before sending the samples, and I will make suitable arrangements for you. ”

After the contact was made, Ye Jiayi asked Tong Wei to make a complete battery as soon as possible, and once the performance tests were qualified, he would seize the time to provide experimental samples to the electric vehicle project of Chengsheng Automobile Company.

More than half a month later, using Tong Wei's scientific research achievements and solid electrolyte and separator materials produced in industrial tests, the New Materials Research Institute developed ten sets of high-energy batteries. Before preparing to deliver the goods to Chengsheng Automobile Company, Ye Jiayi asked Guan Yuntian for advice: "I already said on the phone last time that these sample batteries should be sent directly to Lao Xu, and he will personally arrange the test. Is there any need for you to meet with Lao Xu?"

"Since you've told him everything, isn't it a bit redundant for me to meet him again?"

"I don't think it's redundant at all, after all, Lao Xu is the leader of Chengsheng Automobile Company, and you are the chairman of Changda Group, don't you pay more attention to this matter when you meet to talk about it?"

Guan Yuntian thought for a moment, "Okay, I'll go with you." ”

When I arrived at Chengsheng Automobile Company, in Lao Xu's office, old friends met, and they inevitably greeted each other, "Mr. Guan, you are really silent, you have not met for half a year, Changda Group has made a high-energy battery, I have seen a lot of enterprises, whether state-owned enterprises or private enterprises, Changda Group is the most low-key enterprise I have ever seen." ”

"In fact, the high-energy battery project, only the industrial test process, has been nearly a year, plus Dr. Tong has done a lot of basic research work in the laboratory of the Institute of New Materials, I estimate that there will be at least three or four years before and after, right?" Guan Yuntian said.

"If you don't say that you are very low-key, when we met half a year ago, you and Mr. Ye didn't say a word about high-energy batteries, and now you have made battery samples, which surprised me. Lao Xu said.

"Hey, there is nothing to do with the eight characters, the outside world knows it, once it is not successful, won't it make people laugh? Our management is shy and unwilling to do that. ”

"You guys are drinking tea, and I asked the people from the electric vehicle project to come over and bring the sample batteries over and let them arrange the test and actual test as soon as possible. ”

After speaking, Lao Xu made a phone call, and about ten minutes later, two young people in overalls who looked to be in their thirties pushed the door into the house, "Mr. Xu, we have picked up something." ”

"In the parking lot downstairs, there is a pickup truck with a foreign license plate, you tell the driver and let him pull something and follow you. The two young men turned to leave, and as soon as they walked to the door, Lao Xu stopped them, "You tell Liang Gong and let him arrange testing and testing as soon as possible." ”

"By the way, this is the test report we brought. Ye Jiayi got up and handed the report to Lao Xu.

"The old rule, your test results are yours, and anything that comes to us must be subject to our test results. ”

In the evening, Guan Yuntian hosted a banquet at the most luxurious local hotel for the leaders of Chengsheng Automobile Company, and the guests attending the banquet were not only Mr. Xu, the leader of Chengsheng Automobile Company, but also Manager Jiang of the Liaison and Coordination Department, Manager Jiao of the Purchasing Department, and Mr. Wan, the consultant of the electric vehicle project.

Everyone is an old friend, and several guests know the purpose of the banquet, although Guan Yuntian rarely mentions relevant matters during the banquet, but the guests know it. However, until the end of the banquet, Lao Xu only promised to speed up the progress of the actual measurement and strive to come up with results as soon as possible, but kept silent about other things.

Cruising range is the main indicator of vehicle power battery, in addition, there are charging time, charging and discharging times, weather resistance, oxidation aging resistance and other indicators, which must be strictly measured.

In the past two months, the electric vehicle project team of Chengsheng Automobile Company first conducted laboratory tests on the battery samples provided by Changda Group, and then installed the batteries on the test sample car, and conducted actual measurements and inspections on various indicators under the use of the situation.

After the test, the relevant engineering and technical personnel analyzed and compared the results, in the sample battery provided by the five enterprises that have been tested, the battery life of Changda Group ranks first, it is nearly 100 kilometers more than the second place, the charging time ranks second, six or seven minutes more than the first place, although the number of charging times ranks third, but it is almost the same as the first and second place; in terms of weather resistance, Changda brand battery has the widest range of high and low temperature use, this index ranks first; the oxidation and aging resistance of the battery, Changda brand battery ranks second。 There are several other indicators, although the batteries of Changda Group are not particularly outstanding, but they are not bad.

After analyzing the performance of the battery, the engineers who participated in the test scored the batteries of the five companies, and the results showed that the Changda brand battery scored the first in terms of comprehensive score.

After learning the news, Ye Jiayi immediately called the electric vehicle project consultant office of Chengsheng Automobile Company, "Hello Mr. Wan! ”

"I heard that, Mr. Ye, may I ask you what's the matter?"

"The results of the battery measurement have come out, do you know Mr. Wan?"

"I know, I also participated in the scoring, and your battery comprehensive score ranked first, I am happy for Changda Group, congratulations!" Lao Wan said seriously.

"What does it mean to be the first in the overall score? Do you think Chengsheng Automobile Company's electric vehicles will definitely use Changda Group's batteries in the future?" This is the question that Ye Jiayi is most concerned about.

"This ...... I really don't dare to pack tickets. ”

"Why? Our battery has the first comprehensive score, the key is the farthest mileage, doesn't Chengsheng Automobile Company choose the best battery? This is not in line with your business philosophy!" Ye Jiayi was very puzzled.

"Why are you in a hurry? I just said that I didn't dare to pack tickets, and I didn't say that I wouldn't use your batteries, but there are still some uncertainties. ”
