Today to share the knowledge of Nanshan wireless fast charging car charging, which will also explain the wireless charging scheme in Shenzhen, if you happen to solve the problem you are facing now, don't forget to pay attention to the site, start now!
< ul>Low charging efficiency Since it is for mobile phone charging, the speed of charging is of course the first, even if you can do "wireless" in the application way, but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
Wireless charging does not affect battery life, but early wirelessLow charging efficiency, slow charging, has not been popularized. However, with the continuous development of mobile phone charging technology, according to the information now found, the wireless charging efficiency has reached about 75% to 90%.
Wireless charger under normal circumstances will not harm the mobile phone, wireless charging now the working frequency is done below 1M, so the signal of the mobile phone will not have an impact. Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.
Small workWireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction. High-power wireless charging usually adopts a resonant mode (most electric vehicle charging uses this mode) by the power supply device (charger) to transmit energy to the electric device, which uses the received energy to charge the battery, and at the same time for its own operation.
Electric vehicle wireless charging technology has become popular after electric vehicles become mainstreamThe problem of battery life has not stopped, in order to solve the battery life problem, the various car companies are also trying their best to find a way to solve this problem, in addition to changing electricity and fast charging, in fact, there is a different way, that is, road charging, so that the car on the road running while rushing.
The logic behind the wireless charging technology applied by Germany's WIFERION, which Tesla acquired, in the modified Model 3 is electromagnetic induction wireless charging. The current modified Tesla Model 3 can achieve a wireless charging power of up to 12KW, and the fastest one hourReplenished at 80 kilometers. Full charge could take about six hours.
The wireless charging process will definitely heat up. As long as the temperature is not very high, no problem, you see if there is something around the block, because many times love to put some things on it. Low-power wireless charging often uses electromagnetic induction, such as the Qi method of charging mobile phones, but ZTE's electric vehicle wireless charging method uses induction.
Lveco (IVECO) must be no stranger to everyone, as the world's leading commercial vehicle manufacturer, IvECO products cover light, medium and heavy models. And StellantiThe s Group was formed in 2019 by the merger of the 50 percent stakes of Peugeot Citroen Group (PSA) and Fiat Chrysler Group (FCA). The vehicles that have successfully tested inductive charging are an Iveco electric bus and two Fiat 500s, and this amazing technology is DWPT - dynamic wireless power transmission.
For example, the Tesla model opens FSD to reach the destinationAutomatic replenishment of vehicles behind the ground; Unmanned buses, express vehicles, etc., can also be completely unmanned management; Or you do not have time to find a charging pile for your car, you can send the vehicle to find its own wireless charging pile "foraging"; Wireless charging can also solve the problem that many vehicle charging plugs are not shared at present, just like mobile phones, cars, SUVs, trucks and other different types of different brands of vehicles can use the same charging plate.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through a special electromagnetic field to stop Tesla carsWhen the automatic charge. This technology is not only efficient, but can also greatly reduce charging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence.
According to media reports, Tesla recently launched a $300 "wireless charging platform" that can charge up to three devices simultaneously. This wireless charging pad can provide up to 15 watts of charging power for each device that supports the Qi wireless charging protocol, including iPhone, Android or AirPods headphones. According to Tesla's official website, this charging pad has been opened for pre-sale and will be available in 2023Shipments begin in February.And the charging mode equipment cost is low, so it is very suitable for family scenes as a private charging pile to charge the car. Disadvantages: Due to the small charging power of AC charging pile, the efficiency is low, and the charging time takes about 5-8 hours, the longest or even more than 30 hours.
Power change, is a direct replacement of the battery pack charging mode. When the power battery runs out, it can be replaced with a fully charged battery pack, which can greatly shorten the charging time. The replaced battery will be slowly recharged at the charging station. Wireless charging is a kind of electricity without connectiond=' Quality cars :10 models of wireless charging performance test comparison (5)'> Quality cars :10 models of wireless charging performance test comparison (5)
1. In the comparison of wireless charging functions, it can be found that 6 out of 10 models support manual shutdown of wireless charging function, and Hao Bo GT also supports language shutdown, with excellent overall performance. Slightly regrettably, the BMW Z Buick Veran Pro GS, Chery Arezer 8 and Tesla Model 3 do not support closing.
2, CT6's various high-tech also really affect its car costIts 0T engine has a variable cylinder function, allowing two cylinders to be shut off under low load conditions and running in two-cylinder mode to save fuel. The 10AT gearbox is not a gimmick, its gear ratio range is very large, CT6 cruise at 120kmh speed on the highway engine RPM is only about 1900 RPM, less than 2000 RPM.
3, the highest charging efficiency of Xiaomi and Huawei require the mobile phone to support their own protocols, so we separately tested the Huawei Mate 30 with Huawei wireless charging mobile phone bracket and Xiaomi 10 with Xiaomi wireless charging mobile phone bracket. The standard test uses the iPhone 11 pro with all wireless charging phone stands, and the rule is to keep the phone lit, and test the time required to charge 10% (from 40% to 50% of the phone charge) on all products under test.
The best charging method for pure electric vehicles: conventional charging, that is, slow charging: the traditional way of constant voltage and constant current is generally used to charge the car.
Slow charge. Slow charging, also known as conventional charging and on-board charging, is carried with the carThe charging device can be charged using household power supply 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.
Conventional charging is also slow charging: the car generally uses the traditional constant voltage and constant current way of charging. The charging current is about 15 A, taking a 120A h battery as an example, charging should last at least 8 hours. Generally, after work at night, the charging pile can be fully charged the next morning. This charging mode is currently the common charging mode for electric vehicles.
How many ways electric cars can be chargedIt mainly includes the following ways: Using a portable charger carried with the car: This charger can be charged through the household power supply, which is very convenient. However, the charging speed is relatively slow, so it is more suitable as a way to replenish power. Home charging pile: When buying an electric vehicle, it is generally given a home charging pile along with the car, and the technician will install and debug it at the door.
Inductive charging mode as shown in the figure below, through the electromagnetic induction coupling way to carry out energy conversion to charge the battery. Its characteristics are: easy to use, charging in harsh climatic environments without the risk of electric shock. Charger will 5The ordinary electricity of 0 ~ 60Hz is changed into the high-frequency electricity of 80 ~ 300Hz, and then the high-frequency AC electricity is induced to the electric vehicle, so that the charging time is greatly shortened.
Three methods of constant voltage charging, constant current charging and pulse fast charging are used in the car. First of all, the constant voltage charging method is to connect the charged battery to the charging power supply with a constant voltage, and the charging current will gradually decrease with the increase of the battery voltage. In the charging process, if the battery voltage and electrolyte temperature are high, its polarizationThe action will hinder the passage of current, so that the battery is not easy to fill.
Constant current charging method: The charging current remains constant during the charging process, referred to as constant current charging method, or constant current charging method or constant current charging method. During the charging process, the charging current gradually decreases due to the gradual increase of the battery voltage.
The initial charge is carried out in two stages: first, the initial charge current is charged until the electrolyte releases bubbles, and the single cell voltage rises to 3-4V. Then the current is reduced to 1/2 of the initial charging current, and continues to charge until the electrolyte releases violent bubbles, and the ratio and voltage remain stable for 3h. Total charge timeAbout 45-65h.
Electric vehicles are divided into slow charge, fast charge, power change, wireless charging, mobile charging and other ways according to different charging methods. The specific introduction is as follows: slow charge: also known as conventional charging car charging is the use of portable charging equipment equipped with the car to charge can use household power supply or special charging pile power supply. It's the way passenger cars are used today: on-board chargers and wall-mounted charging piles for homes.
Emergency power supply: This is a new kind of thing like a charging bank, there are two kinds of lead acid and polymer lithium electricity, which can help the loss of power vehicles to start, but also have lighting,Multifunctional supplies for charging mobile phones and inflating cars with an air pump. And they are generally portable, very light, if you have it, you don't need to ask others for help. After use, be sure to charge in time to keep enough power to cope with emergencies.
There are two kinds of charging methods for new energy vehicles, one is to charge with the help of a public charging pile, and the other is to charge with their own charging device, as specified below. Use of public charging piles for charging: As of August 2019, with the increasing number and brand of new energy vehicles in the society, public charging piles for new energy vehicles will be installedThere is also a lot of setup. When charging with a public charging pile, pay attention to distinguish between fast charging and slow charging.
