Tell you the unit conversion in the car's emergency starting power supply

The car emergency starting power supply is a multi-functional portable mobile power product developed in recent years. It can not only support the emergency start of the car, but also can support multiple outputs (such as 5V output, 19V output, etc.). At the same time, the conversion methods of MAH and WH in the car emergency starting power supply have been a question in many people's minds, then you know how to convert the MAH and WH in the car emergency starting power supply? The following small series tells you:

The mAh in an automotive emergency start-up power supply is not an energy unit. It also needs to have the current voltage to be truly energy. Therefore, it can be based on the evolution formula of Ohm's law under the pure resistance circuit: I = Q / t (current = charge, that is, power / time), we can see that Q = It (electricity = current A or mA × time h), so it has Battery capacity in mAh.

The Wh in the car's emergency start-up power supply refers to the amount of voltage, current, and time that are proportional to each other. This amount is called electric quantity. For example, W=Pt (electrical power J=electrical power W or kW×time h), so when the voltage V is described in the battery of the car emergency starting power source, it generally follows Wh in the back, so that it represents how much power the battery can perform. Therefore we can conclude that 1A = 1000mA1W = 1VA. So 1wh=1VAh=1000maVh. If it is a 10V 1000mah battery, we convert it to wh which is 10V*1Ah(1000mah=1Ah)=10wh. As for how much time it can take, we need to look at the power of the appliances.mobile power plant

Looking at the unlimited possibilities created by China from new energy vehicles

n many people's minds, our country’s level of environmental protection technology is not advanced, but for many visitors who visited the previous session of the High Fair, this understanding was completely subverted. Taking the weaker new energy vehicles of scientific research in our country as an example, the “New Energy Vehicles and Connected Vehicles Special Pavilion” specially set up by the Ministry of Industry and Information Technology, one of the organizers of the High-Tech Fair, revolves around the theme of “Green Intelligence, Smooth Travel to China”, not only It only showed the application of new energy vehicles as a whole and parts technology, and also reflected the unlimited possibilities created by China.mobile power plant

In the “New Energy Vehicles and Vehicle Network Special Feature Pavilion”, BYD Company, a local auto company in Shenzhen, demonstrated that the “Qin” model car equipped with the second-generation DM hybrid has taken the limelight. It is understood that as a hybrid car 0 to 100 kilometers to accelerate only 6 seconds, and the maximum speed of up to 185km / h, while the fuel consumption is only 2L 100 kilometers; even in the pure electric driving state can continue to drive 70KM, to deal with the city business Daily needs such as travel, driving by car are more than enough. This BYD's self-developed car can be called an advanced hybrid car in various parameters.

At the Geely booth, the pure electric vehicle EC7-EV, which is still under development, has attracted the attention of many people. The two-cell battery combination with a mileage of about 165km and a long mileage of 250km is designed. The maximum speed is 200km/h, and the charging speed is up to 80% in 30 minutes! The exhibition of such advanced new energy vehicles will allow viewers to imagine the future without exhaustion. It will also make the audience all wonder that the excitement at the High-Tech Fair is so incredible.

Maybe, the current traditional car industry Lin Lin, the brand impression is deeply ingrained, but with the gradual depletion of oil resources, society is increasingly attaching importance to environmental protection, traditional cars will become outdated, new energy vehicles will become a great success New industry. The infinite possibilities that China will create in the cause of environmental protection will be amplified, extended, and even radiated to foreign countries. It is inseparable from the high-tech fair, which provides a professional platform for docking, exchange, and financing. The last session of the Hi-tech Fair has made everyone lament the advancement of China’s new energy vehicles. It is conceivable that the opening of the 17th Hi-tech Fair will be the time when China’s creation will refresh us again.

High performance flexible super capacitor, wearable device battery future!

Recently, scientists from MIT have developed a new type of flexible supercapacitor based on nanowires, which can be said to be a new generation of ideal energy for fitness trackers and other wearable devices.

Life is particularly important for smart watches and fitness trackers that are becoming more and more popular nowadays, but we all know that these devices are generally not large, which means that their battery capacity will not be too high. The best way is to use a small super capacitor - it can provide fast high power electrical pulse. MIT researchers demonstrated experiments on a variety of materials. Eventually they found that carbon nanotubes and graphene were the best performers, thanks to their larger surface area than other materials—the larger surface area means that Accommodate more ions, which is more energy.mobile power plant

MIT chose germanium nanowires as electrodes for miniature supercapacitors. According to researchers, this supercapacitor has a power density of up to 55 W/cc—3.5 times that of a carbon nanotube supercapacitor. In addition, this capacitor also has the advantage of small size. It is reported that the capacitor does not require any metal support, which will greatly save the space required. The cesium that it uses is a relatively abundant substance in nature, so its cost will be relatively cheap. Imagine how much of this technology will be applied to the car's emergency power supply.

Although the current supercapacitor is only confined to the laboratory, researchers say that they will then design and manufacture a version suitable for mass production.

When will new battery technology be stable and lasting?

In addition to battery life can not meet the user's needs, the stability of the battery seems to be a problem, this can be seen from time to time some of the battery explosion, spontaneous combustion events.

Then, a question worth pondering is when will stable, long-lasting new battery technologies enter the market and enter our lives?mobile power plant

Taking into account the serious mismatch between battery technology and digital device batteries, in order to allow consumers to get rid of the current situation of low battery power, major manufacturers have entered the stage of research and development of new battery technologies. The ultimate goal of manufacturers developing new battery technologies is to apply them to their own products as soon as possible to improve the lifespan and stability of the products. From the current point of view, improved technologies based on lithium batteries are the most likely to enter the market first. .

Some consumers believe that the current endurance of digital products is too short, in large part because of the thin and light body designs that designers use. The limitation of the body size determines that the battery used by the device cannot have a large capacity. Because of this, we have seen many designs that improve the battery life, such as the layered lithium-ion battery design of the LG G2 mobile phone and the rapidity of Qualcomm. Charging technology and so on, these technologies have improved the capacity of the battery to a certain extent, prolonged the use time of the battery, but still cannot solve the problem fundamentally.

When will a stable and lasting new battery technology come?

As mentioned above, the improved technology of lithium batteries will not be able to play a role for a half hour. Since the internal batteries do not work, then we need to work hard from external power sources, such as mobile power. In addition to the traditional mobile power supply, we have previously reported many highly mobile power products, such as the Blue Freedom, which is powered by water in the water, and the high-power emergency power supply for European and American markets.

In addition, there are some solar charging mobile phones that can absorb light for charging in some markets, but in essence, lithium batteries are still used internally.

Of course, it is undeniable that researchers have made some achievements in new battery technologies, such as lithium anode batteries, silicon batteries, and nano-generators that absorb noise for power generation, but these technologies can only work in the laboratory. In order to put it into commercial use, it also needs some reasonable measures.

In other words, it will take 5 to 10 years or even longer for the new battery technology to achieve long-lasting, stable, and easy-to-use results. Until then, lithium batteries will continue to provide life for our digital devices.

Car battery maintenance instructions during idle period Prevent rust aging

1, to prevent the metal from rust

Corrosion is mainly caused by the combined action of moisture, oxygen, and corrosive substances in the air. Therefore, for long-term parked cars, the metal surface should be kept clean. Parking garages should always be ventilated to keep the relative humidity of the air below 70. Remove dust, dirt, and moisture from the car in a timely manner. The rust-prone parts and the surfaces of the parts should be coated with oil, grease or wrap. The pores in each assembly should be sealed to prevent air, moisture and dust from entering the interior.

2. Prevent deterioration of rubber products

Rubber products on automobiles, such as tires, transmission belts, and dust covers, often undergo aging, swelling, or deformation, resulting in deteriorated performance and shorter service life. The aging of rubber products is mainly due to the fact that rubber is an unsaturated polymer hydrocarbon that easily absorbs oxygen from the air and oxidizes. At the same time, vulcanized rubber has a certain permeability, and oxygen easily enters the interior to cause oxidation. Especially direct sunlight can promote rapid aging of rubber. After rubber products are contaminated with gasoline and engine oil, they will cause volume expansion, loosening gums, and reduced elasticity. In order to prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.mobile power plant

3, to prevent the mildew of cotton and linen products

Cushions and rugs are easy to absorb moisture. Especially in wet areas and rainy seasons, it is more susceptible to moisture mildew. Therefore, the owner should always check the cotton and linen products on the vehicle, timely dry it, and keep it dry.

4, to prevent the decline in the anti-knock performance of gasoline

The antiknock performance of gasoline depends on the octane number of gasoline. When the car is parked for a long period of time, the octane number of gasoline will decrease with the loss of light components and the increase of the colloidal content, thereby reducing its antiknock property. Therefore, the gasoline tank must be tightly sealed and the temperature must not be too high. Gasoline storage time is best not to be too long.

5, often check the working condition of the engine

Start the engine at least once a month, idling for 4-5 minutes, and check the operation of the engine. If there is any abnormality, it needs to be adjusted and maintained in time. In addition, always check the battery. The electrolyte level of the battery must be 10-15mm higher than the plate. When it is not enough, distilled water should be added in time. The battery should be kept fully charged and the battery should be charged when necessary.

        6, prepare a car emergency start power.

High environmental requirements Lithium explosion is deeply thought

At present, the hidden dangers of ignition, burning, and even explosion of lithium batteries are still not safe to eliminate. Lithium batteries have a high environmental requirement. A slight environmental discomfort can cause explosions and fires. Therefore, we only need to properly maintain lithium batteries when using electric vehicles. Reduce the probability of lithium battery accidents.mobile power plant

Lithium battery explosion causes

Vehicles in the event of a collision can cause the battery anode and cathode materials to break through the diaphragm, and the energy of the battery can be rapidly recharged to the battery at the instant of braking. (When the electric vehicle brakes, the current during energy recovery can be as high as 250~300 amps. Can not be diverted, it is easy to cause a short circuit.) And other reasons will lead to battery short circuit, temperature rise, causing combustion or even an explosion, In addition, lithium-ion battery electrolyte is organic electrolyte, these substances are more likely to catch fire after contact with air.

       The development of lightweight lithium trams seems simple, but its investment in technology and equipment is very large. The assembly of the normative and systematic requirements of the personnel is high, a little technical errors will lead to battery damage or explosion, so only the domestic comparison Large-scale manufacturers have the strength to formally put into production. There are also only a handful of authorized dealers from countries, provinces and cities. Some small manufacturers with poor technical skills do not strictly control production and assembly, and are extremely prone to accidents.

       Therefore, the high-quality emergency starter power supply reminds you that when using lithium batteries, it must pay attention to its use of the environment, such as the general normal lithium battery temperature below 50 °C, do not invest in the fire, do not short circuit.
