Chapter 241 (2/2)

The energy density ratio of the first battery is about 100 kW / kg, that is, each battery of about 1 kg can store 100 kW of power.

However, this battery also has its own defects, that is, there are great restrictions on the output power and output voltage of this battery. The maximum output power is only 100 kW, and the maximum output voltage can not exceed 300 v.

Although the energy density of the second battery is almost the same as that of the first one, which is 100 kW per kg, the weight of the second battery can reach about 5 kg, that is, the maximum storage capacity of each battery can reach 500 kW.

At the same time, the output power and voltage are also higher, up to 500 kilowatts and 500 volts.

Most importantly, although this battery can not supply power in series like the first battery, it works in parallel.

Unfortunately, the second battery is a product that cannot be easily sold. If President Du really needs to buy it, he must first get a license, ”Wang Bin said.

After listening to Wang Bin's words, Du Haili at the other end of the phone was relieved. After all, not to mention the second battery, even the first battery is enough for the helicopter developed by their company. After all, this is a 100 kilowatt power storage! Even if the helicopter developed by their company consumes 10 million electricity, that is, one kilometer per kilowatt, it can definitely give their helicopter a range of 100 kilometers.

So even the first battery is enough for their helicopter, not to mention the second battery. If they can really get the second battery, the endurance of the helicopter developed by their company can be increased to at least 500 kilometers, which is absolutely enough for a civil helicopter.

As for the second battery, Du Haili is confident that the formalities required can be completed.

So he immediately said to Wang Bin, ”Mr. Wang! Your Tiangong technology has really developed high-performance batteries! That's really great. With your two batteries, I think it's not so easy for foreign enterprises to get stuck in the neck of our Kunlun company!” Du Haili said happily.

Then he thought about the electric engine. After all, if you want a helicopter to fly, you can't just solve the problem of energy. You have to solve the problem of engine.

Now, since Tiangong technology has the ability to develop batteries with such excellent performance, it represents Tiangong technology. The technology in power and energy is definitely not simple, so he knows that Wang Bin's Tiangong technology will definitely have high-performance motor technology.

So he asked Wang Bin, ”Mr. Wang, what about the electric engine technology? I wonder if your company has high-performance supporting electric engine technology?”

After listening to Du Haili's words, Wang Bin nodded directly, smiled and said: ”Mr. Du, please rest assured! Our company also has the supporting electric engine technology. Even if you need an electric engine with a power of more than 500 kW, it is not difficult for Tiangong technology. It depends on Mr. Du, what kind of engine you want!”
