The development of the entire new energy vehicle in 2015 and January-March 2016 was very explosive. But calm down, in addition to the joy of harvest, may wish to analyze the factors of the development of new energy vehicles?

Representative of the Vice President of the New Energy Chamber of Commerce of the All-China Federation of Industry and Commerce, and Cheng Haosong, Director of Chaowei Power Co., Ltd.

The first is the six difficulties in the development of new energy vehicles!

The first one is difficult to use. The current core components of new energy vehicles are batteries, mileage, time of use, non-uniform standards, and wear resistance.

The second one is difficult to build, charging piles, and local renovation.

The third is financially difficult. Although there are high subsidies, they are implemented in every car company and some car companies get it.

Fourth, the matching of charging facilities is basically the actual use requirement that cannot be met.

The fifth, the profit is more difficult, the current fraud. To put it bluntly, no money is earned.

Sixth, coordination is more difficult. This is the six core elements that affect the development of new energy.

Followed by six difficulties in core battery components

The first one, the standard is not uniform, the standard of the motor, the standard of the battery is varied, which increases our manufacturing cost.

Second, the customer's personality is customized. The demand for each customer's power battery is different, whether it is power, size, form factor or strategy.

Third, the versatility is relatively poor. The compatibility of batteries from different manufacturers and batteries of different models from the same manufacturer is relatively poor.

Fourth, the manufacturing cost is relatively high. Due to the non-universality of components, a series of costs are incurred, and the costs of procurement, production, processing, etc. are relatively high.

Fifth, the utilization rate of production value is relatively low, and the method and path are more difficult.

Sixth, after-sales maintenance costs are relatively high, and now the battery-integrated instrument group has about 300 kilograms. It is very difficult to carry a 300-kilogram car on the road.

In response to these problems, Chaowei proposed a series of solutions. The one-time standard module effectively circumvents the six issues just mentioned, standard issues, custom development issues, and versatility issues.

What is a once-electric module?

The energy is 1000 watts, the voltage is 48 volts, the capacity is 21 ampere, the size is 230, and the weight is about 5.5 kg. This is a standard module for one degree of electricity.

Why do you make a standard module and its origins.

The 13 batteries plus the communication interface become a battery pack. The one-powered module can be applied not only to electric vehicles, but also to electric bicycles, electric motorcycles, electric tricycles, and smart microgrids. At the same time, the lower the monomer coefficient of the module, the lower the after-sale cost, and the higher the usable value.

Why do we choose 48 volts and 21 pm modules?

First, we found that 75% of the electric bicycles and electric motorcycles on the market have a platform voltage of 48 volts, and its capacity has evolved from the original to high capacity of 20, 40, and 60 ampere. After the voltage, it can meet the requirements of most automotive batteries, and can meet the voltage requirements of most automotive batteries and the capacity platform requirements, including the smart microgrid.

Secondly, Chaowei Lithium has accumulated 10 years of experience. Within this decade, there have been some very successful experiences in technology from batch to batch. At the same time, the weight of 5.5 kg, to meet the convenience.

Why choose a 48 volt, 21 ampere module?

The first is convenience.

The one-time electric module plus the protection method became convenient on bicycle electric and electric motorcycles.

Once the electrical module plus the single-pole acquisition module will become the first electrical module of the car battery, used in electric vehicles.

Once the electrical module plus the single acquisition module, it can be used on the intelligent module.

Changes in voltage or capacity steps in different areas, from 21 amps to 190 amps.

Second is security, and the most critical point.

At present, the mainstream one in the market, there is no way to monitor a single battery in the acquisition module, only the entire battery is monitored. If we take a one-time power standard module, we can monitor a single battery through the acquisition chip, and there is a switch here. When the chip detects that one of the single-chip cores is abnormal, it will not affect the whole battery and it will not work. Here are some image descriptions. This is some of the traditional situations. For example, the battery, some of which can not be used, will directly lead to the entire stop, which will bring customers complaints.

If one of the batteries is broken, it will directly cause the car to stop on the road and cannot be used.

When a battery has hidden dangers during use, there is a safety hazard. If a single module is adopted, these problems can be directly circumvented, and the data cloud platform monitoring by GPS remote monitoring is adopted. We actively discover problems through background monitoring. The situation is the same. Through passive control, it becomes active prevention, and an abnormal situation of a single unit is found in advance to provide services.

Again, the convenience of manufacturing.

The design of the standardized solution will greatly reduce the socket. At the same time, we can take economies of scale, implement scale and automation, greatly improve our quality and reduce our costs.

Fourth, the convenience of after-sales.

When our battery is in different situations and in a violent situation, the current practice is that the customer is not satisfied, and if there is a problem, the after-sales service personnel are notified to go to the site for testing. This detection cycle is often 7-30 days. After we adopt modularization, we can realize data monitoring to detect problems in advance after adopting GRS and GPS data monitoring. After the problem is discovered, we will serve customers in a peer-to-peer manner. There is data monitoring in the background. We will produce the instrument group according to the information collected in the background or the information given by the customer. A small module will be brought to the customer's use site, and the entire group of batteries can be on site. Poor module replacement greatly reduces logistics costs, including social costs, and shortens the social service cycle, greatly improving customer satisfaction.

Fifth, product economy.

We also conducted a rough analysis on the economic side. This analysis does not necessarily fit the basics of everyone. After modularization, each group of battery recycling increased by more than 30 yuan.

Sixth, this product has also obtained the national invention patent and the new patent used, and it is also used in many aspects.

This is the solution for the module battery in batch application. Now, the actual application cases such as 370 volts and 24 ampere have been applied in batches. This is two electric vehicles independently developed by Chaowei. The light steam soldiers have been independently researched and developed by Chaowei for three years, and are characterized by intelligence, modularity and light weight. (Maiqiao), these two car module batteries, with intelligent, lightweight, modular and other product features.

In retrospect, through the application of modularity, on one hand, it can effectively solve the problem of its gradient utilization. When it comes to gradient utilization, we can really use gradients. The battery can be used on electric bicycles and used on microgrids. After modularization, its series of costs, convenience of installation, timeliness of social services, and improved recycling value are also insignificant for enterprises and even for the industry. Chaowei is to create two ecological chains. The first one is from the power battery to the power system, to the electric vehicle manufacturing and sales, such a production chain. The other, from energy storage batteries to key components of energy storage, to energy storage systems, energy storage stations, energy storage and power to achieve the strategic development goals of Chaowei future. In the future, Chaowei is not only a company that develops and produces batteries, but also a new energy enterprise with a competitive battery system and a storage battery system as its core.
