Recently, the electric motor brand nanoFLOWCELL from Liechtenstein released the new QUANT 48Volt concept sports car, using the latest low-voltage flow battery technology, the maximum power will reach 762 horsepower, the top speed of 300km / h, 0-100km / h acceleration 2.4s, the maximum cruising range Or over 1000km.
I believe that everyone has been familiar with this kind of news, but in fact, for our ordinary consumers, this kind of "surreal concept car" is still far away from us, the most important thing is the price. . . . . . According to the news, the future price of this car is as high as RMB 10 million. However, the reason for mentioning this news is that this concept car uses an uncommon "flow battery".
The types of batteries for electric vehicles, the most common ones are lithium batteries, nickel-metal hydride batteries, etc. (of course, there are many small classifications, which are not mentioned one by one), and for flow batteries, the earliest brand during 2014 The concept product was launched, and the Geneva Motor Show, which opened in March, will bring a real car show. Here I will introduce you to what is a flow battery. . . . . . And whether the flow battery can become the mainstream driving method of electric vehicles in the future.
Flow battery
It is not rigorous to say that the flow battery is a "liquid" battery, it is not a type of solid battery, which is also known from the name of light. What exactly is the flow battery?
In fact, the flow battery is not used as a battery system in electric vehicles at the earliest. Japan uses liquid flow batteries for facilities such as peak shaving and wind energy storage, which is enough to prove the strength of the flow battery.
Of course, if the storage capacity of the flow battery is considered to be an advantage, it can be said to be both happy and credit for pure electric vehicles. The reserves are large, the natural volume is large, and for a car, the large-capacity battery is not suitable for loading the car, which is the contradiction.
(But according to the news, the concept car of the nanoFLOWCELL brand mentioned earlier has developed a high-density flow battery, which will be introduced in detail below)
Advantages of flow battery
The following two figures clearly show the working principle of the flow battery:
In fact, the biggest difference between a liquid flow battery and a normal lithium battery pure electric vehicle is that the flow battery plays an "engine" in the overall structure of the automobile, and is not a common energy storage mechanism. The positive and negative electrolyte chambers continuously supply fuel to the flow battery, and a redox reaction occurs in the film to generate an electric current.
Having said that, everyone is sure that the most important thing is where its advantages are, that is, the advantages of the flow battery compared to lithium batteries:
The rated power and rated energy are independent, the power depends on the stack, and the amount of energy depends on the electrolyte. The amount of electrolyte can be increased at will to achieve the purpose of increasing the capacity of the battery.
The battery has an indefinite shelf life and a long shelf life. The electrolyte is recycled, there is no problem of deterioration, but the battery separator resistance increases after long-term use.
Instant recharge can be achieved by changing the electrolyte.
In fact, there are still many advantages for the flow battery. Since there are so many advantages, why not spread? The most important reason is that the technology is not mature and the cost is very expensive, which makes it impossible to popularize.
The concept of flow battery introduced by the nanoFLOWCELL brand has been shown to the world as early as 2014, and after three years of technology development and precipitation, it will finally usher in the true concept of the concept car at the upcoming Geneva Motor Show.
What is the "magic place" of the nanoFLOWCELL brand QUANT 48Volt concept car? Is it really difficult to solve the flow battery technology?

Innovative energy
nanoFlowcell? It is the most innovative and powerful energy storage system in mobile and stationary applications. Compared to conventional batteries, nanoFlowcells provide energy in the form of a liquid electrolyte (bi-10N) that can be stored away from the battery itself. Like conventional flow cells, positively charged and negatively charged electrolyte liquids are stored in two tanks, respectively, and pumped through a converter in a separate circuit, like a conventional flow cell or fuel cell (nano flow cell) The actual unit of the system). The two electrolyte circuits are separated only by the permeable membrane. Ion exchange occurs once the positive electrolyte solution and the negative electrolyte solution pass each other on either side of the converter membrane. This converts the combined chemical energy in the bi-ION into electricity, which can then be used directly in the electrical consumer.
Scalable energy
Use nanoFlowcell? The separation of technology, energy converters and energy storage media means that the stored energy is no longer dependent on the cell size. This is where the flow battery is different from the traditional type of battery. Use nanoFlowcell? The energy available depends on the concentration of the electrolyte in the electrolyte liquid and the volume of the electrolyte container. Thanks to its unlimited scalability, the nanoFlowcell can therefore be adapted to a wide range of applications.
Fast charge and discharge
Instantaneous recharging by replacing the electrolyte is also a characteristic of the flow battery.
Innovative charge carrier
Let me say more here:
bi-ION is nanoFlowcell? Liquid energy carrier. The power density of an electrolyte is comparable to the power density of today's lithium-ion batteries, but its energy density is five times that. bi-ION is the perfect fuel for environmentally compatible and sustainable electric drives.
Is bi-ION a pair of nanoFlowcells? The power characteristics of the system are critical. Through years of research, the company has developed a special charge carrier that makes the power and energy density of the solution significantly higher than all liquid batteries currently on the market.
High energy density
The company's charge carriers have been developed to allow significantly higher concentrations of previous electrolytes in conventional flow cells. Compared to an electrolytic tank in a fixed device having a volume of several thousand liters, only the tank volume of a conventional automobile is required to achieve the performance of the QUANTINO 48VOLT. In the current state of development, an energy density of 600 Wh/l is achieved using bi-ION. What is the nanoFlowcell running on the bi-ION compared to the lithium-ion battery used in most electric vehicles? It can provide enough energy to reach 5 times that of conventional electric vehicles.
Whether it is mass production and technical problems
All of the above are just advantages to the power system, the following is based on the advantages of the concept car itself.
Hub motor technology
The QUANT 48Volt concept car is equipped with an electric motor in all four wheels, allowing four wheels to independently output torque. This is equivalent to not requiring the differential to adjust the torque between the wheels.
Long cruising range
The company has solved the problem of liquid battery density. According to the official cruising range, the new car will have a cruising range of more than 1000km, which is also a long battery life that cannot be achieved by the technical level announced today.
Powerful power system
According to official data, the new car has a maximum power of 762 hp and a top speed of 300 km/h and a 0-100 km/h acceleration time of 2.4 s.
If you say shortcomings, the author believes that the biggest drawback is technical problems and expensive prices.
Although the technology of this concept car is advanced, it still cannot achieve mass production. From the perspective of development funds, the price of foreign media before a car will not be less than 10 million RMB.
The mass production level cannot be achieved, and even if there is a strong technical reserve, it will stop at the concept. As consumers, we cannot be immersed in the beautiful concepts created by these companies. Looking at the technology of today's electric vehicles, it takes a certain amount of time to achieve such a high level. It is still unknown to really bring qualified products to market.
Written at the end
In fact, it is not touted how advanced the technology of the QUANT 48Volt concept car, of course, these are only in the theoretical value. It is an indisputable fact that electric vehicles are indeed the development trend of the future automobile industry. Regardless of the promotion of the government or the company, our consumers only care about whether the product is convenient for daily life.
What is it for buying a car? The definition of a car is nothing more than tools, props, and toys. Most of the electric vehicles on the market are defined as tools. However, a series of social problems such as charging piles cannot be alleviated. It can be said that they spend money to find crimes. Borrow a quote from the famous big V in the rim. Are you eating for charging or charging for dinner?
In short, whether electric vehicles are environmentally friendly or not, there are still some doubts. I believe that this is by no means the real concern of most car owners. When it is possible to solve the charging problem and stability problem under the vehicle, it is very important, otherwise everything will be "cheat money."
Transmission And Distribution Pole
Steel poles are commonly used to carry several types of electric power lines, distribution lines and lighting system. Distribution lines carry power from local substations to customers. They generally carry voltages from 4.6 to 33kV for distances up to 30 miles, and include transformers to step the voltage down from the primary voltage to the lower secondary voltage used by the customer. A service drop carries this lower voltage to the customer's premises.
