Super-divine civilization begins with the civilian use of dark energy technology

Chapter 148 Tianmeng Bicycle is on sale

The first to appear on the market were electric bicycles.

The structure of electric bicycles is relatively simple.

But electric bicycles contain many parts, and electric bicycles also have many functions.

The first is the battery. Tianmeng bicycle uses Baineng graphene battery.

Baineng graphene battery has the characteristics of small size and light weight. After a series of safety packaging, the Tianmeng bicycle battery weighs 1KG and has a storage capacity of 1kwh, which is one kilowatt hour.

The energy consumption of an electric bicycle per 1.2 kilometers is 1.5~60 kilowatt-hours of electricity. One kilowatt-hour of electricity can allow the bicycle to run at least [-] kilometers.

Then there is the charger. The charger is a device that replenishes power to the battery. It is generally divided into two-stage charging modes and three-stage charging modes.

Two-stage charging mode: Constant voltage charging first, the charging current gradually decreases as the battery voltage rises. After the battery power is replenished to a certain level, the battery voltage will rise to the set value of the charger, and then it switches to trickle charging.

Three-stage charging mode: When charging starts, constant current charging is performed first to quickly replenish energy to the battery; after the battery voltage rises, it switches to constant voltage charging. At this time, the battery energy is slowly replenished and the battery voltage continues to rise; the charge termination voltage of the charger is reached. When the battery is on, it switches to trickle charging to maintain the battery and supply the battery’s self-discharge current.

Tianmeng Automobile Factory’s electric bicycles have been modified with chargers. The chargers are directly connected to Baineng Graphene batteries and directly charge Baineng Graphene.

When an electric bicycle is sold, it will come with a charger.

Since the battery of Tianmeng bicycle is removable, customers can buy a charger and place it at their work place, so that they can be charged while working.

Next is the controller. The controller is the component that controls the motor speed and is also the core of the electric vehicle electrical system. It has under-voltage, current limiting or over-current protection functions.

The intelligent controller also has multiple riding modes and self-checking functions for the vehicle's electrical components.

The controller is the core component of electric vehicle energy management and various control signal processing.

The controller includes the handlebar, brake handle, power sensor, torque sensor, etc.

Turn handles, brake handles, etc. are signal input components of the controller.

The handlebar signal is the driving signal for the electric vehicle motor to rotate.

The brake handle signal is an electrical signal that the internal electronic circuit of the brake handle outputs to the controller when the electric vehicle brakes. After the controller receives this signal, it will cut off the power supply to the motor, thereby realizing the brake power-off function.

When the electric vehicle is in a power-assisted state, the power-assisted sensor is a device that immediately detects the pedal force and pedal speed signals while riding.

The controller automatically matches manpower and electricity based on the electric driving power to jointly drive the electric vehicle to rotate.

The most popular power-assist sensor is the central axis bilateral torque sensor. Its product feature is that it can collect the pedal force on the left and right sides, and adopts a non-contact electromagnetic signal collection method, thereby improving the accuracy and reliability of signal collection.

With this power-assist sensor, e-bike riders can use electricity while pedaling.

The combination of manpower and electricity is realized.

When the battery is completely discharged, the bicycle can be pedaled home.

Finally, there is the motor. The most important accessory of an electric bicycle is the motor. The motor of an electric bicycle basically determines the performance and grade of the vehicle.

Most of the motors used in electric bicycles are high-efficiency rare earth permanent magnet motors, which are mainly divided into three types: high-speed brush gear + wheel reduction motor, low-speed brush motor and low-speed brushless motor.

The motor is a component that converts battery energy into mechanical energy to drive the electric wheels to rotate.

There are many kinds of motors used in electric vehicles in terms of mechanical structure, speed range and energization form.

Common ones include: brushed geared hub motor, brushed gearless hub motor, brushless geared hub motor, brushless geared hub motor, high disk motor, side-mounted motor, etc.Tianmeng Bicycles chose brushed and geared hub motors.

What Qiao Guojin wants is for Tianmeng Bicycle to seize most of the market as soon as it is launched.

Electric bicycles should be made the best, and Tianmeng Bicycles should be the best among electric bicycles!
Of course, choose the best motor.

In addition, Tianmeng bicycle has an advantage. Compared with lithium batteries, Baineng graphene batteries are 5 kilograms lighter.

Since the battery has been reduced, we might as well reduce the weight of the motor, reducing the entire electric bicycle by 10 kilograms.

Although this increases the cost of the motor, it can add an advantage to the electric bicycle and is a good improvement.

The lighter weight means less effort when pedaling. In today's society, effort saving is of course the most important thing.

Other electric bicycles seem to retain the function of the pedals. In fact, the position of the pedals has been changed to a battery storage area, making the pedals very short. The result is that the torque is small, the bike itself is bulky, and the short pedals are very heavy to pedal. Hard work.

The Tianmeng bicycle is different. The battery is light in weight and small in size. The battery does not take up space and the pedals can be made into normal pedals.

Everyone in the company is full of confidence in Tianmeng Bicycles, and the results are as expected.

As soon as the Tianmeng bicycle was released, it was sought after by the public.

Although removable batteries are common, the two-pound battery with a range of 60 kilometers surprised the public.

If there is still a battery weighing two kilograms, the company also has a battery weighing one kilogram.

Contrary to the company's expectations, the most popular product turned out to be a one-pound battery.

Although the range of this battery is only 20 kilometers (the packaging weight accounts for a small part).

But for most people, the distance from home to work is only a few kilometers, and the distance from home to work is only a dozen kilometers at most.

A battery weighing one pound is just right.

And the battery can be hundreds of dollars cheaper!

If the previous shared bicycles were aimed at the last few hundred meters.

Tianmeng Bicycle aims at the entire distance. With the speed limit of 20 kilometers per hour for electric bicycles, it can be reached in up to an hour on an electric bicycle.

An hour is actually about the same as taking the subway.

Because the subway also takes into account the waiting time, the subway is not crowded in places such as Beijing, Shanghai, Guangzhou and Shenzhen.

If you are unlucky, an electric bike may be faster than taking the subway!
Of course, people who have a distance of more than 20 kilometers can also buy a two-pound battery, and the range of 60 kilometers is enough to reach the company.

Therefore, as soon as Tianmeng bicycles were released, they were well received by office workers.

For most office workers, riding an electric bicycle is better than squeezing into subways or buses.

Of course, in addition to office workers, the other customer groups are takeaways and couriers.

Needless to say, it is the best choice for delivery people because it is lightweight and has a long range.

However, what is unexpected is that deliverymen are not satisfied with the 60-kilometer range. They usually buy three two-pound batteries at once, just for backup.
