Chapter 180 Ni-MH Batteries (for Subscription)

"Battery?"

Cao Mao and others were even more confused, talking about the motor, how did it involve the battery?
Ichiro Ozawa knew that if he didn't tell these laymen thoroughly, he couldn't make them give up, so he turned around and gathered the surface of the "Houlang" hydrofoil surfboard in front of him from the workbench, and then opened the pedal The hatch cover reveals a battery block about 38 centimeters long, 12 centimeters wide and 6 centimeters thick.

Remove it casually, and then remove the baffle to remove the electrodes, and soon the lineup of battery blocks will be revealed. Inside are all dark green strip-shaped dry batteries, densely packed in two layers.

"This is... a chewing gum battery?" A high-end Fengmao company immediately recognized the battery inside: "Yes, it is a chewing gum battery, a new product just developed in Japan a few years ago!"

"Mainland manufacturers actually use chewing gum batteries!"

"Didn't you say that this kind of battery is a special battery developed for Walkmans? Why is it put on sports equipment?"

"That's not the point. The point is how do mainland manufacturers have this kind of battery production technology? I heard that this technology is unique to Japan!"

……

The executives of Fengmao Company can be said to be talking about it. There is no way. Although the chewing gum battery is a new product that has only been born in recent years, thanks to the influence and publicity of Japanese products, many people still know about it.

Especially this group of well-informed executives of Fengmao Company has paid attention to the trend of this new product for a long time.

It's just that I didn't expect to see this new type of battery, which is claimed by Japan as an exclusive technology, in a product of a mainland manufacturer.

"Cough cough~~~"

At this time, Ichiro Ozawa coughed twice, suppressed the comments of Fengmao executives, and then pointed to the battery and said: "There are indeed chewing gum batteries inside, but more precisely, they are high-density nickel batteries. Compared with the popular nickel-cadmium chewing gum battery on the market, this kind of nickel-hydrogen battery is more environmentally friendly when the energy density remains the same.

But these are not the key points I want to talk about, because compared with the idea and design of this product, what kind of battery to use is not the final thing! "

As soon as this remark came out, everyone including Cao Mao frowned and didn't understand the meaning of Ozawa Ichiro's words, but Ozawa Ichiro put it off and looked at Fengmao's senior executives Suddenly asked: "Before this, who of you thought of using dry batteries in series to form a battery box and become the energy source of the motor?"

"This one……"

After hearing this, many Fengmao executives realized that this simple, direct and even rude method had never occurred to them.

It's not that I dare not think about it, but that I can't think about it at all, because the traditional motor uses alternating current and needs a special battery to drive it.

The battery is a small thing that weighs more than ten kilograms, and a larger one weighs tens of kilograms or even hundreds of kilograms.

That's all, the key is that the energy density is not high, and no three or four groups can't move the traditional motor at all, so even if you know that there is a simple way, it can't be used, because the dry battery belongs to direct current, which is different from the AC motor. The matching degree is too low to be used, so what else do you want?
Why do mainland manufacturers who produce "houlang" hydrofoil surfboards dare to do it?

Because people use DC brushless motors, it does not involve the complicated mechanism of DC to AC conversion, and the battery pack can be directly connected to the motor to complete the entire upgrade kit.

"Ni-MH batteries have a high energy density. According to our calculations, this battery pack can guarantee the use of the hydrofoil surfboard for 3.5 hours. The number of recharges is slightly less than 300 times, but the overall cost is very low. It’s probably less than $100, and the people who buy these hydrofoil boards are mostly middle-class, and sub-$100 replacement costs are nothing to them.”

Ichiro Ozawa looked at the gray-faced Fengmao executives, and his tone became very helpless: "Brushless DC motors, rare earth permanent magnets, and this set of battery packs are outstanding products even in Japan. , there are no more than 5 manufacturers that can make it. If your Fengmao company wants to imitate, you must first solve various supporting facilities, then reserve relevant talents, and finally complete sets of processing equipment. For you Fengmao, it is absolutely astronomical.

What's more, even if you invest at all costs, will it really pay off?As far as I know, the price of the 'Houlang' pro upgrade kit in North America is only 320 US dollars, but according to our calculation, the cost of Fengmao to produce similar products is at least 1200 US dollars, the difference between the two is nearly 4 times, how do you compete? "

"Then there is no other way?"

At this time, Cao Mao spoke slowly. At this time, the nearly 80-year-old Cao family speaker was like a dying person who was dying, holding on to the last straw, holding Ichiro Ozawa's hand, struggling His begging: "Mr. Ozawa, please find a way, any conditions are fine, as long as there is a way!"

But this time Ichiro Ozawa didn't speak, but slowly pulled his hand back from Cao Mao.

Cao Mao immediately understood everything, and immediately rolled his eyelids, and fell headlong amidst the exclamation of "Mr." and "Chairman".

Ichiro Ozawa helped put the fainted Cao Mao into the ambulance, then returned to his office, closed the door, took out a piece of letter paper from the drawer, took out a pen and quickly wrote a letter of resignation, Then seal it with an envelope.

Then he took out a piece of fax paper and wrote on it: "Recently, Zhujiang Machinery Factory in the Mainland has developed very rapidly, especially in the technology of motors, rare earth materials and batteries. Department attention!"

After finishing writing, Ichiro Ozawa opened a booklet, on which were densely recorded many communication numbers, and Ichiro Ozawa soon stopped in front of the number marked "Mitsubishi Heavy Industries Technical Analysis Headquarters", and then left Go to the fax machine and send your handwriting back to Japan!
……

In Japan, in the Industrial Technology Analysis Headquarters on the 15th floor of Mitsubishi Heavy Industries headquarters, a section chief looked at the fax he had just received, and glanced at several staff members under him: "Zhujiang Machinery Factory... Does anyone know anything about it?"

In the office, four or five male and female employees looked at me and I looked at you, all shook their heads in unison, the head frowned, and threw the fax in his hand aside: "File first, we are currently working The focus is on Baosteel's production line..."

……

Zhujiang factory, in the assistant factory director's office, Wen Dawei didn't know that their factory was almost blacklisted by a well-known Asian commercial espionage organization. Zhiyu: "Dear Wen, you are a genius, yes, I already knew you were a genius, the 'Houlang' pro upgrade suit is simply amazing, even better than Miss World's figure!"
