5g will become the most frequently used word in 2020. In the past year, 45 telecom operators around the world have begun to deploy 5g. Obviously, 5g will change our lives at a speed far faster than 4G. As the world's largest mobile phone chip supplier, at this CES, Qualcomm also showed its overall layout of 5g era for the first time, initially completing the comprehensive coverage of mobile phones, computers, cars and cloud

different from the previous press conference in which mobile phone business occupied the C position, the biggest space of this CES press conference of Qualcomm was about the automobile business. For the first time, the automotive field has become the focus of Qualcomm's layout. In addition to the Internet of vehicles business that has been laid out before, this time, Qualcomm has also extended its tentacles to automatic driving

automatic driving platform with more flexibility and lower power consumption at the press conference of Qualcomm on the eve of CES, Qualcomm officially launched the new snapdragonride platform, officially listed various problems encountered in current automatic driving, and said that its own platform is one of the most advanced and scalable open automatic driving solutions in the automotive instry. This kind of scene is like, one day, a former mobile phone chip maker suddenly stood in front of a pile of car Tier1 and sighed: "there is no one who can take a taxi. I have to come to the automatic driving solution."

with the development of 5g and artificial intelligence technology, more and more technology companies have joined the automotive instry, using the advantages of chips and software to enable intelligent vehicles and accelerate the intelligent and networking process of vehicles. Perhaps, owning a more intelligent and convenient car will come true earlier than we think

There are two kinds of batteries for electric vehicles: lead batteries and lithium batteries

lead-acid battery is divided into 36V and 48V:

36V, and the common capacities are 10Ah and 12Ah; Some are 14Ah, 17ah, 20Ah

the common capacities of 48V are 10Ah, 12Ah, 14Ah, 17ah and 120ah; Some of them are 15ah, 16ah, 18ah, 22ah, 24Ah

the Li ion battery is 48V and the capacity is 12Ah

extended data

differences between electric vehicle lead-acid batteries and lithium batteries:

1. Battery life: the service life of lead-acid batteries is generally about 2 years, while lithium batteries are more rable, and the service life is mostly 4-5 years; And the lead-acid battery cycle is generally within 300 times, while the lithium battery cycle is more than 500 times

2. Easy to operate: compared with the light body with only 2.5/3kg lithium battery, the lead-acid battery with the same capacity generally weighs about 16 / 30kg; The battery is not only large in mass but also large in volume; Compared with the lead-acid car, the lithium tram has a detachable design, which makes it more convenient to ride and carry

3. Cost performance: at present, the market price of mainstream lead-acid batteries is about 450 yuan, while the price of lithium batteries is about 1000 yuan; The prices of the two types of batteries are different, and the corresponding prices of electric vehicles are also quite different. At the same time, the warranty period of lithium batteries is one year longer than that of lead-acid batteries, which can be guaranteed for two years

4, range: the same 48V battery, full charge, lead-acid / lithium battery electric vehicle range are almost the same, depending on the speed, motor size and other factors. Of course, in terms of battery capacity, lead-acid batteries will be slightly larger than lithium batteries

Electric vehicles

Finally, let's share a piece of gossip. Ding Lei, the founder of China express, was once the co-founder and global vice chairman of LETV, and was deeply influenced by Lao Jia's car making

Ding Lei made Gao He, which can be regarded as a tribute and continuation to FF

if you like the content of the car, you must remember to pay attention to us: KM has the deep and practical automobile content every hour. We make complaints about it either in love or in recommendation. p>

Wang Hewu, Deputy Secretary General of China electric vehicle 100 people's Congress, is currently concentrating on the field of commercial vehicles. Zhangjiakou City has deployed a number of hydrogen fuel cell buses, which are in very good operation conditions and have no major problems in winter

conclusion: new energy vehicles will be on the right track

before, the development of new energy vehicles in China was not a normal development trend, car companies relied on government subsidies excessively, and the quality problems of vehicles have been criticized, and vehicle spontaneous combustion accidents occurred from time to time

however, the 100 people's Congress saw that car companies and suppliers have invested more energy in vehicle R & D and paid more attention to vehicle quality

in addition, Miao Wei, Minister of the Ministry of instry and information technology, said frankly on the spot that on July 1, 2020, the subsidies for new energy vehicles will not further decline, which means that the subsidies will decline, but will not be completely cancelled. However, the responsible persons of a number of automobile enterprises also expressed that they are ready for the decline of subsidies

generally speaking, most new energy vehicle enterprises have survived the most difficult year of 2019. With the rection of proction cost of electric vehicles, the enhancement of profitability and the improvement of market acceptance of electric vehicles, the electric vehicle instry is expected to enter a recovery period in 2020

Recently, we will develop from automatic driving to Moore's law in the next ten years, and the resolution of both on-board computing power and sensors will be improved hundreds of times in 2030. Thousands of tops chips, hundreds of millions of pixel cameras and high-resolution solid-state lidar will become the standard configuration of automatic driving

as long as there are enough data and sufficient R & D investment, the leading enterprises of intelligent electric vehicles can realize level 4 automatic driving, and automatic driving will become the operating system of intelligent electric vehicles, not the function configuration. By 2030, we believe that level 4 automatic driving will become the standard configuration of every intelligent electric vehicle, and users will not choose an intelligent electric vehicle without automatic driving ability

in terms of electric technology, the ultra fast charging technology of 300-500km in 10 minutes will be popularized in an all-round way, so as to make the charging experience close to refueling, which will become a necessary condition for accelerating the popularization of electric vehicles. More green power generation, charging network with energy storage capacity and V2G (vehicle to grid) will form a new commercial value chain. HPC super charging station will have a higher return on investment than gas stations, and better support the popularity of electric vehicles in business

3. Changes in the market

the full popularity of automatic driving in 2030 will polarize consumers' demand for cars

some people think that the car will become the exclusive space for autonomous driving, and hope to have the exclusive space for themselves and their families. This space has the atmosphere and design we like, sufficient power, super computing power, the best VR and AR environment. It's a space for entertainment, social interaction, work and family. Smart electric vehicles will become more value-added exclusive space than residential buildings. We believe that the sales volume of private intelligent electric vehicles will not decrease, and the output value of each vehicle in its whole life cycle will increase significantly

other people think that the self driving car is a means of transportation. To solve the travel problem from point a to point B, we only need to consider the efficiency and cost. This kind of demand competition will make the travel cost including the self driving taxi drop sharply, and the self driving public transportation will even become a free service. Enterprises and the government can obtain benefits through value-added services

ideal car will adhere to its mission: to create a mobile home and a happy home. For more families to create self driving exclusive space, create happiness, loyal to our own brand mission

2. Instry challenges in 2030

1. Challenges of competition

the competition of traditional fuel vehicles is the competition of instry and machinery, and the overall competition pattern in recent decades is relatively friendly, more like league matches in football, rather than cup matches and elimination matches. Even a brand with a small market share can seize the market segments through its own unique positioning and proct characteristics, and survive and develop healthily

the end of the competition of intelligent electric vehicles is the competition of data and chips, which will soon become a knockout competition such as the football World Cup. Each brand will face the qualification of the group stage and one round of knockout competition. Referring to the market share of China's smart phones in 2020, the top five brands account for 96.5% of the market share. In 2030, the market competition and market share of intelligent electric vehicles will be very similar. Only by gaining more than 25% of the global market share, can we have the opportunity to become the leading enterprise in the global intelligent electric vehicle instry

2, energy challenge

the convenience of charging is still the biggest challenge in the popularization of electric vehicles. The total number of parking spaces where private charging piles can be installed is extremely limited, which will hinder more fuel vehicle owners from buying smart electric vehicles. Only when the charging station is as convenient and fast as the gas station can all consumers replace fuel vehicles with smart electric vehicles

in the next decade, the ideal car will choose two routes in parallel: 1. The extended range electric platform (power bank) with urban pure electricity and long-distance power generation as the user value; 2. Ten minutes to add 300-500 km of 400 kW ultra fast charging high voltage pure electric platform (super charger). All we do is to provide energy solutions for free travel and accelerate the popularization of electric vehicles from the perspective of user value

3, the challenge of organization

traditional fuel vehicles run in a relatively controllable world. Planning, process and control are the most effective management modes, which also proce powerful instrial enterprises and organizations. The purchase of a traditional fuel vehicle has almost no change after three years, while an intelligent electric vehicle is growing almost every month, which means that the management mode will be completely different, and the demand for talents will also be completely different

human beings are the most advanced intelligent creatures on the earth. The operation modes of human intelligence are: 1; 2. Decision making; 3. Implementation; 4. Feedback. Specific to a proct, an organization and its partners, how to effectively use the operation mode of human intelligence and build the management and operation system of the proct and organization is a compulsory course for every intelligent electric vehicle enterprise

this is an unprecedented vision and goal of a Chinese enterprise, but we have the responsibility to make a difference under such a general situation. Although the traditional automobile instry has developed for more than 100 years, the competition of intelligent electric vehicles will basically be divided in 2030

we hope that through the struggle of all our partners, we can achieve a real event in the best decade of our life and in the best decade of our instry. Make this decade the proudest one in our life, and don't let our life leave a huge regret

(2) market and strategy, how do we do in 2025? 1. The time rhythm of 2025

2015-2020 is the stage of ideal automobile from 0 to 1. Like most start-ups, our resources and funds are relatively scarce at this stage, so survival and hematopoietic capacity are the core goals of enterprise development at this stage. We have delivered the ideal one, experienced the test of complete proct, R & D, supply chain, proction, sales and organizational ability, and achieved the first sales volume of China's new energy SUV in 2020, with the most basic survival and hematopoietic capacity

this is a huge challenge. We must maintain abundant talent and capital reserves, take user proct value as the goal, take technology R & D and proct R & D as the core driving force of the enterprise, invest the most resources in R & D and talent reserves, and do not take shortcuts

first, they are generally family users with children, and often need three generations together. They are the additional purchase of Mercedes Benz, BMW and Audi, and the replacement purchase of Volkswagen, Toyota and Honda. The design of ideal one fully considers the needs of every family member including the host, hostess, elders and children. Good driving experience, continuous growth ability, front passenger screen, second row electric seats, third row passageway and huge trunk are all designed for this group

looking forward to the next five years, we will expand the coverage of user groups: a wider range of home users, anyone who wants to have their own "home". Around the core mission of creating a mobile home, we provide more intelligent electric vehicles, including a variety of procts from the second generation extended range electric X platform, high voltage pure electric whale platform, and high voltage pure electric shark platform. We adhere to the brand positioning of luxury intelligent electric vehicles, and widely cover the price of 150000-500000, Let more people have high quality mobile home

User: family user

user demand: exclusive space for automatic driving

price range: 150000-500000

brand positioning: luxury intelligent electric vehicle

brand mission: create mobile home and happy home

the strategic goal of ideal automobile in 2025 is to achieve 20% market share and become the first intelligent electric vehicle enterprise in China

the first key supporting element is the comprehensive technical ability, which is composed of leading proct R & D and technology R & D, with user proct value as the core

the second key supporting factor is the commercial ability with market share as the core and leading sales service, proction and supply chain

the third key supporting element is the strategic resource support capability with intelligent organization as the core and leading talents, data and funds

only when the comprehensive strength is the first, can we really have a chance to win the world cup of intelligent electric vehicles

I hope that every partner of ideal automobile can carefully read the 2025 strategy, implement the core objectives and requirements of the enterprise into specific work, and make their business decisions and work results better support the enterprise 2025 strategy. Welcome the most wonderful and challenging decade in our life, and realize the decade that we are all proud of
