1, for the human body: wireless charging technology is safe and harmless to the human body. The resonance principle used by wireless charging is magnetic field resonance, which is transmitted only between coils resonating at the same frequency, and other devices cannot accept the band, in addition, the magnetic field used by wireless charging technology is itself harmless to the human body.
2, effectLow rate: energy storage and transmission efficiency is less than real contact. Slow charging speed: Due to low efficiency, the charging speed is slow at the same input power. Although wireless charging can be unplugged, the distance between the phone and the charger is very small. However, the electromagnetic energy loss is still not small, and the power received by the general mobile phone is about 75% of the power sent by the charger.
3, efficiency problem Wireless charging is subject to the development of technology, charging efficiency is still relatively poor, because the wireless charging itself is small, and the actual performance is not stable.
4, this means that if the radiation of the wireless charger exceedsIndustry grade wireless module. 4g wireless data terminals are also very convenient to use, customers only need to recharge and activate after the power can be used, the elderly can also easily master the use of skills.
In fact, do not deliberately open, which day 4G mobile phone card can be used directly 4G, that is the best. Anyway, the contract says that cmwap Internet 20 yuan cap, did not say what 2G3G4G, you go to open 4G but not good, when the time to tell you 4G separate charges, waiting for the shutdown.
Mobile 4G data 20 yuan package is 20 yuan monthly Internet traffic charge. 20 yuan set =150M domestic general flow 150M provincial general flow; Do not change the main package do not change the number, do more than 20 yuan traffic package helicopter 4G! Complimentary 10M data via APP. It should be noted that the flow refueling package is opened in the same month, effective in the same month, and the fee is deducted immediately after the successful opening, valid until 24:00 on the last day of the month. It needs to be reopened for the next natural month.
Home charging pile charging Many people will install home charging after buying new energy vehiclesElectric pile, this is more convenient, can be charged at any time, do not need to go everywhere to find charging pile. Charging method: Set the charging time and stop time on the charging pile, or it can be operated in the APP of the phone.
Portable charging: Portable charging refers to using the portable charging cable that comes with the car to connect to the ordinary household socket to charge. This is a very convenient way to charge, as long as you can find an outlet, you can charge. Home charging: Home charging pile is the most common kind of charging pile. The average private user will buy an electric car with a home charging pile. Of course, the pile alone is not enough, you also need to have a parking spaceAnd the property agrees to install.
Slow charge. Slow charging, also known as conventional charging, vehicle charging, is the use of portable charging equipment carried with the car to charge, can use household power and charging pile. The charging current of this slow charge is small, generally about 6A~32A, and the current can be directly carried out by two-phase AC or three-phase AC.
There are a variety of charging methods for new energy vehicles, which are described in detail below: fast charging stations and mobile charging vehicles fast charging stations can be divided into large, medium and small according to the scale, and their power ranges from 90 kilowatts to 300 kilowatts, which can meet 3 to 10 vehicles at the same timeCharging requirements for electric vehicles. This charging method is characterized by fast forward and fast out, and the owner does not need to leave the vehicle during the charging period. In just 30 minutes, the battery can reach 80%.
Portable charging: Portable charging refers to the use of the portable charging cable attached to the car and the ordinary household socket connection for charging. This is a very convenient way to charge it, as long as you can find an outlet, you can charge it. Home charging: Home charging pile is the most common charging pile. The average private user will buy an electric car with a home charging station. Of course, it is not enough to have piles, but also to have parking Spaces, and the property agrees to securityPretend.
There are three ways of charging new energy vehicles on the high speed: wireless charging, also known as inductive charging. The biggest feature is safety. Even in rain and snow, there is no need to worry about the risk of electric shock. Car charging case. When the car is idling, the charging box can be fully charged. Charging in the high-speed service area.
First of all, wireless charging, also known as inductive charging, its biggest advantage is security. Even in bad weather conditions, such as rain and snow, it can be ensuredThere is no risk of electrocution. Secondly, in-car charging boxes are another convenient option. When the car is idle, the on-board charging case can replenish the battery. Finally, charging piles in high-speed service areas are the most common way of charging at present.
Using public charging piles for charging: As of August 2019, with the increasing number and brand of new energy vehicles in the society, a large number of public charging piles for new energy vehicles have also been set up. When charging with a public charging pile, pay attention to distinguish between fast charging and slow charging. In general, fast charging can be used when charging with a public charging pile, at 1-2The vehicle can be fully charged within an hour, without delaying the normal running of the car.
Driving an electric car to travel, then how to solve the charging problem? Charging method, wireless network charging, also known as magnetic induction charging: the biggest feature is safety, timely rain and snow do not have to worry about the risk of electric shock accident. On-board charging box: The key is used for emergency charging, when the car is empty, it can fill the on-board charging box with electricity,The most important thing for long-distance supercars is to use the on-board charging box.
Self-driving travel whether to drive new energy vehicles, is a lot of people have to think about the problem, in this regard, has explained to you the attention of driving electric vehicles, mainly from the driving habits to further alleviate the endurance anxiety of electric vehicles. In fact, in addition to these methods, we can also choose models that are more convenient to supplement energy, and fundamentally solve the problem of new energy vehicle energy supplement.
Pure electric vehicles running long distance need to solve the following problems: pure electric vehicle charging problem, pure electric vehicle battery range, high-speed driving economy, pure electric vehicle battery useLife span. Charging time is reduced from 4-8 hours to 15-50 minutes. In March 2018, in order to verify this problem, Xiaopeng Motor officials also specially carried out a Guangzhou-Beijing trip test, and finally arrived safely, so from the point of view of pure electric vehicles themselves, they have got rid of the limit of the range radius.
When solving the charging problem of electric vehicles, it is necessary to pay attention to the following points: When the vehicle starts, do not vigorously power up. When going uphill or in the wind, it is best to use the foot pedal to help, which is good for the battery and the motor. Once fully charged, wait until the red light is on and then float for 1-2 hours. Don'tOverload and overweight driving, driving found that the instrument shows insufficient power, to use human riding.
There is no way that only someone to drag back, but it is recommended that the general travel before the journey planning. Different EVs (that is, pure electric vehicles), the current charging method is different, for example, if you drive 50 KWH below 200 kilometers of low-speed electric, then things are much simpler, these cars are generally equipped with simple car charging, you can use home winter battery life is short, think about opening a warm wind, the battery life is absolutely acid cool.
