Contemporary Ampere Technology Co., Ltd., are you ready to change the electricity?

Easy car original-"The car is hungry"? Please, chocolate battery.

Yes, you are not mistaken. Today's manufacturers really take pains to name their products to gain attention. What blade batteries and jelly batteries? This is not because Contemporary Ampere Technology Co., Ltd. has brought chocolate batteries to EVOGO, which is a recently released brand for changing electricity. The car is out of power, come to the power station at any time and instantly "resurrect with blood". It seems that the scene in the game was really brought to the real world by "Wang Ning", which makes me ask: Wei Lai, are you ready to fight?

We all know that Weilai has always been an advocate and leader of power exchange and energy supplement. Before contemporary Amperex Technology Co., Ltd. entered the bureau, only Weilai, a rare form of power and money trading in China, had begun to take shape. Weilai official website shows that up to now, there are 784+ power stations, a considerable number of which are still being popularized and covered. On NIO Day last year, Weilai also announced plans to have more than 65,438+0,300 power stations in China. After the implementation, users' mileage anxiety will be greatly improved, and the process of changing electricity can be completed in one song, which will greatly promote the development of electric vehicles.

So, is the sudden entry of Contemporary Ampere Technology Co., Ltd. a whim or a long-planned one? We might as well review some key contents of the conference. Look at the highlights and advantages of the power exchange of contemporary Anpu Technology Co., Ltd..

What new gadgets did 0 1 EVOGO bring?

At present, the new energy automobile industry has entered a new stage of explosive growth. 202 1 12 The retail penetration rate of new energy vehicles in China reached 22.6%, with more products and more diversified services. However, mileage anxiety, energy replenishment anxiety and purchase cost have been puzzling consumers of new energy vehicles.

In response to the pain points of consumers, EVOGO launched a combined power exchange solution of power exchange block+fast power exchange station +APP at the press conference. The three modules form a closed loop, and it is very simple to replenish energy.

The most striking thing is chocolate SEB. Each chocolate battery pack can provide a cruising range of about 200km, and the bicycle can support up to 3 chocolate battery packs. In other words, the maximum battery life can reach about 600km.

"Chocolate for Battery Block" is a specially developed and mass-produced battery with three characteristics: small and high energy, free combination and minimalist design. With the CTP (Efficient Grouping) technology of contemporary Amperex Technology Co., Ltd., the weight energy density and volume energy density of "chocolate battery changer" exceed 65,438+0.60 Wh/kg and 325Wh/L, and a single battery can provide a battery life of about 200 kilometers, which can adapt to 80% of vehicles developed by pure electric platforms that have been listed in the world and will be listed in the next three years. The humanization point is that consumers can choose 1-3 battery according to different mileage requirements when changing electricity. Improve the efficiency of power exchange and reduce the cost of power exchange. In addition, the "chocolate power exchange block" adopts wireless BMS technology for the first time, and there are only high-voltage positive and negative interfaces outside, which greatly improves the reliability of plugging and unplugging components.

In addition, "one electric car with multiple cars" is also a highlight of this electricity-changing block. "Chocolate battery changer" can be applied to buses and logistics vehicles A00 to B and C ... The power changing station can adapt to all brands of vehicles using "chocolate battery changer", which breaks through the adaptation barrier between batteries and vehicles and realizes the freedom of choice of battery changing vehicles.

Consumers can "rent electricity on demand" and freely choose the number of rented power exchange blocks according to their own usage scenarios and habits. At present, most private car owners only use 10-20% of battery power in daily use scenarios, but in order to alleviate mileage anxiety and recharge anxiety, they have to buy large-capacity models and pay a lot of sunk costs. Through "rent electricity on demand", consumers only need to rent one electricity block when commuting in daily cities. If you want to travel long distances, you can choose two or three electric gears to really increase or decrease and realize the freedom of electricity use.

The second point is the quick change station, which has four characteristics: small area, fast circulation, large capacity and all-weather. Each standard station only needs three parking spaces, and it takes about 1 minute to change electricity for a single block. The station can store 48 power exchange blocks to ensure that users can replace fully charged blocks at any time without waiting for a long time. At the same time, the power station can also provide versions suitable for climate and environmental conditions in different regions.

As the last item of the closed loop, APP acts as a link between different modules and consumers, and provides interconnection and services among people, vehicles, stations and electric blocks. In the future, more and more functional modules will serve consumers through APP.

Finally, the conference announced the combined power exchange version 00 1 of FAW Pentium NAT, a member of EVOGO "Little Green Ring Family". In the future, EVOGO will select ten cities to launch the first batch of power exchange services and release more brands of power exchange models.

What is 02 CTP technology?

Earlier, we mentioned that the newly released chocolate battery block uses CTP efficient grouping technology, so what does CTP mean? How does this technology help improve the performance of batteries?

We know that the structure of power battery is generally battery → module → battery pack. A unit is the smallest unit, and a module consists of units. In order to improve the safety of the whole battery system, the battery pack is composed of modules.

This three-layer structure is the standard of typical power battery pack. On the one hand, there are modules to protect, support and integrate batteries. On the other hand, each module independently manages some batteries, which is helpful for temperature control, preventing thermal runaway and facilitating maintenance. However, everything has advantages and disadvantages. The existence of modules reduces the space utilization rate of the whole battery pack, resulting in low grouping efficiency. While the energy density of single battery exceeds 300Wh/kg, the energy density of battery system is still around 160Wh/kg due to the traditional grouping method of battery pack. Therefore, the efficient group technology proposed by contemporary Ampere Technology Co., Ltd. is to solve this problem.

Removing modules and integrating battery cells directly on the battery pack, namely CTP(Cell to Pack), has the advantages of reducing the gap between modules and increasing the volume energy density of the whole battery pack.

But at the same time, although the above idea of de-modularity seems simple, it is not easy to realize. No module means higher process difficulty, which means higher requirements for battery quality and consistency. In the past, if a battery unit has a problem, it can be controlled in the local module through the BMS battery management system so as not to affect the whole battery pack. However, after removing the module, if there is a problem with a battery unit, it may affect the whole battery. Therefore, the modular technology of contemporary Ampere Technology Co., Ltd. is not only an outstanding innovation of battery system technology, but also reflects the technical level of battery cell design and manufacturing. 202 1 CTP (efficient grouping) scheme of Contemporary Ampere Technology Co., Ltd. has entered version 3.0. Under the same volume, the power consumption of the whole package is increased by 13% and the weight is reduced by 10% compared with the previous version.

What are the advantages of CTP?

1. Improve the cruising range: remove the module, fill the battery pack with more batteries, increase the energy density of the battery pack, and directly improve the cruising range of the whole vehicle. Under the same battery chemical system conditions, the energy density of Ningde CTP battery increased by10-15%;

2. Safety promotion: Doesn't it mean that disassembling the module will reduce the safety of the single battery? You know, before improving the performance of batteries, we always rely on improving the energy density of batteries. Before the arrival of CTP technology, the improvement of energy density was mainly achieved by changing from lithium ferrous phosphate to ternary lithium, and ternary lithium batteries were more dangerous than lithium ferrous phosphate. CTP improves the energy density at the battery pack level, which means that ordinary ternary or even lithium iron phosphate batteries with high safety can be used at the battery monomer level to achieve sufficient driving range. Under the same mileage effect, the safety of the whole vehicle is undoubtedly improved. Of course, there are still safety risks for CTP with high nickel system.

3. Cost reduction: From the cost point of view, the number of parts in the whole battery pack is reduced by 40% and the production efficiency is increased by 50% due to the elimination of parts such as wiring harness and cover plate in the module link, and the material cost and manufacturing cost of CTP battery pack will be increased. If the lithium iron phosphate battery with lower cost is used, the cost of the whole battery pack will be further reduced compared with the traditional ternary battery pack.

Therefore, at present, companies are constantly innovating in the structure of batteries. Under the condition of relatively fixed chemical properties, improving physical structure is indeed a wise choice and breakthrough.

Advantages of Power Exchange of Contemporary Ampere Technology Co., Ltd.

Let's take a look at the position of Contemporary Ampere Technology Co., Ltd. in the whole battery industry:

As can be seen from the above table, in 20021year, the installed power battery capacity of Contemporary Ampere Technology Co., Ltd. was 80.5 1GWh, accounting for 52. 1% of the domestic market, far ahead of BYD, which ranked second, and occupied half of the domestic power battery market.

Contemporary Amperex Technology Co., Ltd. has unparalleled advantages in the installed capacity of power batteries and the ability of industry integration, and the promotion of the development of power exchange mode this time also has innate conditions that other manufacturers do not have.

First of all, the huge shipment and battery supply, at least the power station has been built, and there is no need to worry about the source of batteries for power exchange; Secondly, Contemporary Ampere Technology Co., Ltd. acquired Guangdong Bangpu Cycle on 20 15, realizing a circular industrial chain integrating R&D, production, sales and recycling, and creating an ecological closed loop of "battery production → use → recycling and resource regeneration". Therefore, the cascade utilization and recovery of batteries are effectively solved; Thirdly, owning a holding battery after-sales service enterprise can solve the safety problem of power batteries and improve the after-sales service quality of power batteries. In addition, in terms of urban cooperation, financial cooperation and power grid, Contemporary Ampere Technology Co., Ltd. has also launched a lot of cooperation recently, which should be a long-term plan for power exchange.

So what's Weilai's attitude towards the entry of contemporary Amperex Technology Co., Ltd.?

In this regard, Weilai, who insisted on adopting the power exchange scheme, said in an interview: "Welcome the innovation and business model that is conducive to facilitating electric car owners and convenient travel." And pointed out that "Weilai and Contemporary Ampere Technology Co., Ltd. are both shareholders of Wuhan Weineng, a battery asset company, and have been cooperating in this field. It is necessary and beneficial to invest resources in the construction of electric vehicle energy-supplementing infrastructure, promote the popularization of intelligent electric vehicles and promote the development of transportation in the direction of low-carbon and environmental protection. At present, the most important competition is the competition between electric vehicles as a whole and fuel vehicles, so all innovations and business models that are convenient for electric vehicle owners and convenient for travel are good news for all electric vehicle brands. "

It can be seen that Weilai expressed an open and welcome attitude towards the entry of contemporary Amperex Technology Co., Ltd.. After all, at present, how to promote the popularization and perfection of the electricity communication ecology requires the concerted efforts of all Qi Xin. Multi-enterprise joint promotion can achieve a win-win situation and is a convenient choice for consumers.

04 written at the end

The arrival of the power exchange mode has greatly improved and eased the long-standing anxiety of electric vehicles. Imagine that the popularity of the future power exchange mode will make it as efficient and fast as refueling, so the popularity and possession of electric vehicles will be improved to a greater extent.

Whether it is contemporary Amperex Technology Co., Ltd. or Weilai, or a new enterprise in the future, it is the greatest interest to jointly create a complete, safe and convenient e-commerce transaction ecosystem for consumers.

I believe that in the near future, more enterprises will join in, and the joint participation of battery factories and car companies will lead the process of accelerating the popularization of battery replacement mode. Now, whether it is fast charging or battery replacement, whoever can really help consumers solve the problem of battery life anxiety and make it easy to replenish energy will be the most needed technical route in the industry. Let's wait and see.
