Overview of Transportation Energy Power System Reform

In the long history of mankind, we have experienced two changes in transportation, energy and power system. Each change has brought great changes to the production and life of human beings, and has also contributed to the economic take-off of the leading countries or regions. The first revolution took place in the 1760s, which was mainly marked by the birth of steam engine technology. Coal and steam engine greatly improved the productivity of human society, initiated human industrial economy and industrial civilization, and triggered the industrial revolution in Europe, making European countries become the world economic powers at that time.

The second change took place in the 1870s, when oil and internal combustion engine replaced coal and steam engine, transforming the world economic structure from light industry to heavy industry, and at the same time contributing to the economic take-off of the United States and bringing human beings into the oil-based economic system and material prosperity.

Today, human once again came to the traffic at the intersection of energy power system reform, the third change will be driven by electricity and battery (including fuel cells) to replace oil and internal combustion engine, the mankind into the era of clean energy, we bold predictions, the third traffic energy power system change will lead Asia's economic take-off, Asia overtook the us as the engine of the world economy.

HEV ( Hybrid Electrical Vehicle ), BEV ( Battery Electric Vehicle), FCEV ( Fuel Cell Electric Vehicle ) and other small electric vehicle are popular at present.

Classification of small electric vehicles

But here, get rid of those “ big guys “ we only talk about small electric vehicle which includes :

Electric Bicycle

Electric Moped

Electric Scooter

Electric Golf Cart

Electric Wheelchair

Electric Sightseeing Car

Electric Logistics Vehicle

...

These small electric vehicles are widely used in different places and market demand is increasing. Currently, lead-acid batteries, nickel-metal hydride batteries and rechargeable lithium batteries are used as power batteries.

Description of Lead-Acid , Ni-Mh, Rechargeable Lithium Battery

1) Lead-Acid battery

Lead-acid batteries are strictly limited in use because of their high pollution. The Ministry of Industry and Information Technology (MIIT) issued a new national standard for the safety of electric bicycles in 2018, stipulating that the maximum speed of electric bikes should not exceed 25 kilometers per hour. The vehicle quality (including battery) is forbidden to exceed 55 kg; Must be able to pedal; The motor power shall not exceed 400 watts; The nominal voltage of the battery does not exceed 48 v; Do not modify the appearance of the vehicle at will. The standard will be officially implemented on April 15, 2019.

According to the new national standard, the dominant lead-acid battery in electric bicycles may not meet the technical requirements.

2) Ni-Mh battery

Nickel-metal hydride battery technology is mature, the purchase and use cost is low, but the self-discharge rate is large, the specific energy is small, can only be used as a transitional battery.

3）Rechargeable Lithium Battery

Only rechargeable lithium battery can match electric vehicle comprehensively, which has the characteristics of long cycle life and small self-discharge rate. It developed in the 90 s, high-capacity and energy than Ni-MH batteries, longer cycle life and smaller self-discharge rate. They can meet the requirements, such as volume, life.

Rechargeable lithium battery anode material sort is more, mainly includes lithium cobalt acid, lithium manganese acid, nickel manganese cobalt (ternary materials) and lithium iron phosphate.

Among the existing anode materials, lithium cobalt oxide is the most industrialized, the most mature technology and the largest production variety. It is mainly used in the field of small batteries such as mobile phones and digital products.

But because of the high price of the raw materials (cobalt and nickel), heavy pollution, and there is a risk of overheating fire or explosion when batteries in the large-scale. Therefore, the anode materials lithium manganate, ternary materials and lithium iron phosphate) have better safety performance and lower cost. Therefore, the current industrial investment is mainly concentrated on these materials.
