Slow charging (conventional charging, on-board charging) is suitable for on-board chargers and family wall-mounted charging piles tram wireless charging principle , its current and power are relatively small, and the general charging time takes 6-8 hours. Fast charging (ground charging, emergency charging) includes two forms of charging station and mobile trolley, mainly through the non-on-board charger using high current to directly charge the battery, so that the battery can be charged to 80% in a short timeThe power on the right can be fully charged in 1 hour.
A charge of new energy vehicles within 5-10 hours, which is the most common charging mode, in addition, slow charging is the safest and most conventional way of charging electric vehicles, that is, AC charging, the charging process takes 6-8 hours. Charging method of new energy vehicle: portable charging gun.
Normal charging usually takes seven to eight hours, enough to fully charge the battery by 70 to 80 percent. However, this charging method has a lower current and has less impact on the battery. But it is worth noting that the fast charging current is extremely high, although capable of being semi-smallThe faster charging speed is achieved within the time limit, but it may have potential damage to the battery, so the balance between time and battery life should be carefully balanced when using. Before discussing "how long does it take for a pure electric vehicle to charge", we must first familiarize ourselves with the two main ways of charging electric vehicles: charging piles (often called "fast charging") and portable chargers (also known as "slow charging"). The charging pile is famous for its fast speed, usually half an hour for the battery to fill 80% of the capacity tram wireless charging principle ; Portable chargers are slower, taking about 6 to 8For an hour.
At present, there are two main charging methods, one is fast charging, and the other is a portable charger. Fast charging generally uses high-power DC charging, which can fill 80% of the battery capacity in half an hour, while portable chargers take 6 to 8 hours to complete the charge. Fast charging devices are often referred to as charging piles, while slow charging includes both 16A and 32A power chargers.
1, first of all, upgrade the choice of new energy vehicles with better endurance performanceType is the key. Compared with traditional fuel vehicles, new energy vehicles usually have a longer driving range and faster acceleration performance, which has a significant improvement effect on alleviating driving anxiety. Secondly, with the help of advanced intelligent technologies, such as 100km induction charging and automatic driving technology, the endurance can be significantly improved to ensure that the driver can safely travel longer distances.
2, there are three ways to solve the problem of endurance anxiety of new energy vehicles. The first way can be replaced with super lithium iron phosphate. The main reason for the short life of electric vehicles is that the cost of power batteries is too high, and the use of ordinary high-nickel ternary lithium batteries wants to set a reasonable priceGrid will inevitably reduce capacity, mileage will naturally be very low.
3, when the endurance of the new energy vehicle reaches the degree of inter-city performance, it can successfully reach the destination without charging after full charge, so that it can effectively alleviate the problem of endurance anxiety. ... Of course, in addition to increasing the endurance, increasing the number of charging piles and shortening the charging time is the fundamental way to completely solve the endurance anxiety, only this problem can be solved, in order to ultimately eliminate the problem of endurance anxiety.
4, the power of an electric car is fixed, we can change the lineDriving mode to improve actual range, such as avoiding frequent acceleration and deceleration; Try to keep a constant speed at 60~80 kilometers per hour, especially do not run the highest speed of electric vehicles, which is the most power consumption; Minimum speed turtle speed is also not advisable. In this way, the actual operating range can be improved, and the maximum potential of the battery can be brought into play.
5, in addition, improving the coverage of new energy vehicle charging stations is also an effective way to eliminate endurance anxiety. The high coverage of charging stations can maximize the convenience of electric vehicles, ensuring that the vehicle can be charged at the right place at any time while driving to meet the driver's journeyCountries can't afford it, only Europe can afford it? '> Wireless charging in electric vehicles, China can not afford to use, only Europe can afford to use?
As for the electromagnetic wireless charging scheme, aluminum can also be used to replace copper as raw materials to a certain extent, thereby reducing manufacturing costs. In summary, electromagnetic induction and magnetic resonance are the most suitable choices for electric vehicles, and the models currently in the development and application of wireless charging are basically using the above two methods.
It is worth mentioning that the Ministry of Industry and Information Technology recently released the "wireless charging (power transmission) equipment radio managementIn the interim Provisions, it is clear that the charging power limit of mobile phones and other mobile devices is raised to 80W, and the management provisions are also applicable to the wireless charging of electric vehicles. This has undoubtedly injected new impetus into the development of wireless charging technology for electric vehicles. In short, electric vehicle wireless charging technology still faces many challenges, but its development prospects are broad.
Compared with the traditional charging method, the wireless charging system can indeed greatly improve the convenience of charging, so that it is stopped and charged, and the wireless charging device has lower space demand. In addition, relying on magnetic resonance wireless charging, it is theoretically possible to charge while walking, and even haveHope to solve the range anxiety of pure electric vehicles.
Charging indicator system: The charging indicator system mainly refers to the voltmeter or charging indicator on the instrument panel, which is used to indicate whether the working state of the generator is normal. If the charging indicator light is on or the voltmeter pointer is lower than 24V while the car is driving, it means that the generator is not charging or the charging amount is too low, and the charging system needs to be repaired.
Contact type. Contact type is also called coupling or conduction type. The contact charging method connects an AC power cable with a plugThe cable plugs directly into the electric car's socket to charge the battery. Its advantages are simple and high efficiency; The main deficiency is that the charging current is small and the charging time is long. (2) Induction type.
The charging process of electric vehicles is mainly divided into six steps: physical connection, low-voltage auxiliary power-on, charging handshake, charging parameter configuration, charging, charging end. When charging an electric vehicle, the first condition to be met is the matching of the charging gun and the charging interface, that is, the physical connection. If the charging gun can be normally inserted into the car, the basis for charging is established.
1, the application environment is harsh wireless charging transmitter is generally arranged on the ground of the parking space, if the parking space is outdoor, you need to ensure that even in lightning, rain and snow, high temperature exposure, low temperature freezing and other harsh environment can still work effectively. Even indoors, you need to consider the possibility of being run over by wheels or trampled by pedestrians.
2, the principle of wireless charging is magnetic induction, the magnetic flux of the magnetic field must be very large, the charging efficiency is low, which is harmful to human health and interferes with electronic equipment. And the vast majority of the cars don't pick upDevice.
3, wireless charging is through the electromagnetic field. Not the radiation risk of high-power fast charging. Only slow charge. It'll take a few hours. Hours. Why save a few seconds plugging in a socket? And wireless charging to improve efficiency requires precise berths. And wired charging actually requires very low parking accuracy, long wires ah. And there's plenty of room for improvement in wired charging. Like a plug that comes off easily without being crushed.
4, electric vehicle charging needs to be fast, wireless charging power is difficult to meet the standard of wired charging, in addition, car wireless charging because it belongs to high-power electromagnetic field,Safety has also been questioned. 5, now the main problem of electric vehicles or charging time is too long, the efficiency is too low, and from a long time ago there are companies proposed to use wireless charging technology in the car, recently there are companies to do it, but at present it is only a small range in the test, the future want to popularize is also difficult. In fact, before this road wireless charging began, there have been companies that have used this technology, but the final effect is not very ideal. 6, in theory, electric vehicle wireless charging technology can not only greatly improve the user's car experience, but also for the futureThe final stage of the unmanned use scenario of autonomous driving is set. One of the important reasons for the delay in really going to the market is that various countries failed to develop a unified standard for the technology as soon as possible, resulting in a series of "chain reactions", resulting in difficult to scale, marketization.
1. Unlock the vehicle, open the hatch cover and protection cover of the AC charging socket; Connect the vehicle plug that comes with the charging pile to the vehicle socket; Follow the instructions of charging equipment to start charging; Combination instrumentLight up the charging connection indicator, and display the charging screen; Unlock the vehicle, set the charging device, or charge the device fully. 2, wireless charging, also known as inductive charging: the biggest feature is safety, even in rain and snow do not have to worry about the danger of electric shock; Car charging box: mainly used for emergency charging. When the car is idle, the car charging box can be fully charged, and the most important thing for long-distance sports cars is to rely on the car charging box; Traditional constant voltage constant current charging Charging electric vehicles: that is, the traditional charging method, just like charging an electric bicycle, just plug into its own socket.
3. ElectricHow to charge a home electric car How to charge a home electric car charging method: Use a home power supply: plug the car charger into the 220V16A power outlet at home, it takes more than 8 hours to fill, more suitable for charging at night; Installation of charging piles: The charging piles installed at home are basically slow charging piles, the power is about 2000 to 3300 watts, and the battery can be full in about 1 hour.
4, the common charging methods of electric vehicles are as follows: portable charging Portable charging refers to the use of the portable charging cable attached to 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. But its charging speed is not flattering.
5, the first, fast charging port. This kind of charging port is generally in the front position (Jianghuai IEV5 on the contrary, the same below), which belongs to the DC charging mode and requires the use of high-power fast charging piles. Charging time is relatively rapid, generally tens of minutes can be charged to 80%. The second, slow charging port. This kind of charging port is generally on the rear side of the car, with the gasoline car refueling port.
