1. It is reported that Sweden is building a new lineThe road, which charges electric vehicles while driving, calls it "the world's first permanent electrified road." Why so many attributes? This is because Sweden, Italy and the United States are also interested in this technology.
2, 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 the Xiaomi 10 with Xiaomi wireless charging mobile phone bracket. The standard test uses the iPhone 11 pro with all wireless charging phone mounts, and the rules are phone insuranceWith the screen on, test the time required to charge 10% (from 40% to 50%) on all products under test.
3, compared with the electromagnetic induction type, the characteristics of the electromagnetic resonance type is obviously more in line with the needs of electric vehicle wireless charging. Soon after the technology demonstration was announced, WiTricity received offers from Audi, BMW, Chrysler, Jaguar, Nissan and Toyota to work with it. However, after receiving financial support, the development of wireless charging technology applied to electric vehicles has not been as good as expected.
4, carThe car only needs 10 seconds to accelerate 100 km per hour, has a top speed of 140 km per hour, and can reach a range of about 389 km in WLTP test mode, which is 30% more than the range of the old model. It takes only 30 minutes to charge the 145km range with 50kW charging, and 9 hours and 25 minutes with 7kW charging to fully charge the vehicle. However, this powerful and popular small electric car starts at €20,000 in Europe, which is a bit expensive.
5, and Geely Galaxy L6 mainly 100,000 ~ 150,000 level intermixing market, whether it is performance, intelligent configuration or rideComfort in the same class is very advantageous, can be said to be a higher quality and high value of the home car products. The Deep Blue SL03 is the main extended-range model, which is more suitable for users who have low power requirements and are more inclined to pure electric or extended-range models.
1, Tesla's acquisition of the German WIFERION, in the modified version of the Model 3 applied wireless charging technology, behind the logicIt's electromagnetic induction wireless charging. At present, the modified Tesla Model 3 can achieve a maximum of 12KW wireless charging power, the fastest one hour to make up 80 kilometers, full may take about 6 hours.
2. For example, the auto recharge of the Tesla model after the FSD arrives at the destination; 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 vehicles do not share charging plugs, just like mobile phones and carsDifferent types of vehicles of different brands such as SUVs, trucks can be charged using the same charging plate.
3. First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. 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. 4, according to media reports, Tesla recently launched a $300 "wireless charging platform" that can be used for up to three units at the same timeThe device is charged. 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, the charging pad has been opened for pre-sale and will begin shipping in February 2023.
1, however, in terms of current technological development, the efficiency of wireless charging is lower than thatLine charging. If wireless charging is used, there is no exposed connector when wireless charging of electric vehicles, completely avoiding safety hazards such as leakage and electricity running. And wireless charging can hide the power supply and transformer underground, so that the car can be charged in the parking lot or on the street special charging points, so wireless charging is very convenient.
2, low charging efficiency Since it is for mobile phone charging, charging speed is of course the first, even if you can do the application of "wireless", but for the most basic requirements of charging speed can not be reached, then the experience will probably be a discount.
3, wireless chargingElectricity does not affect battery life, but early wireless charging is low in efficiency, slow in charging, and 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%.
4, 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 stillVery high, more energy saving.
5, 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. 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.
6, wireless fast charge is not very fast, nor very slow. Wireless fast charge is much faster than wireless fast charge, and slower than wired fast charge. Wired charging headThe power output to the wireless fast charge base is not the wireless fast charge output power but the wireless fast charge input power. Charging time of more than 2 hours of wireless fast charge, not as fast as the wired fast charge of 1 hour and 30 minutes, is not fast charge. Unexpectedly, the wireless fast charging efficiency of 60% when the 18W is charged for 2 and a half hours.
1, there are two charging methods for new energy vehicles, one is to charge with the help of public charging piles, and the other is to use their own charging devicesLine charging, 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, 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.
2, home charging is one of the most common charging methods, the general electric vehicle purchase will be equipped with a home charging pile. Of course, the installation of home charging piles requires a parking space and the consent of the property. When you want to use a home charging post, just park the vehicle next to the charging post and plug in the chargeCar cigarette port, the other end of the link wireless charger; After fixing the position of the wireless charger, make sure that it is stable and will not slide, put the phone on and charge it.
First of all, fix the car wireless charger to the appropriate position in the cab, connect the wireless charger data cable connector to the car's cigarette lighter interface, and connect the other end to the wireless charger, after fixing the wireless charger, ensure that the wireless charger will not slip, the wireless charger can be used normally.
Fixed wireless charger. Owners need to buy a suitable wireless charger equipment, and then fix the wireless charger on the vehicle, fixedThe location should be convenient for the owner to take. Connect the cigarette lighter. One end of the USB data cable of the wireless charging device is connected to the wireless charger, and the other end is connected to the car cigarette lighter interface. Put it in your phone. Put your phone in a wireless charger and it will start charging.
Fixed position: First, fix the car wireless charger in the appropriate position in the cab. You can place the charger in the center console, under the front seat, or on the edge of the windshield. Make sure the charger does not interfere with driving and does not slide or move. Connect the data cable: Connect one end of the USB data cable of the wireless charger to the car cigarette port.The other end is connected to a wireless charger. Make sure the connection is secure and does not come loose or break.
Car wireless charging as long as the mobile phone supports wireless charging function can be charged, if the mobile phone does not support, you need to connect a wireless charging patch on the mobile phone. At present, the car charger basically uses the QI protocol (wireless charging standard), and the mobile phone and the car charger that meet this protocol can be matched for charging. So as long as the transmitter and receiver are QI certified, they can basically be charged.
Start by securing the in-car wireless charger in the proper position in the cab of the Chevrolet Coruse. Secondary nullOne end of the USB data cable of the cable charger is connected to the car cigarette port, and the other end is connected to the wireless charger. After it is confirmed that it is stable and will not slide, put the phone on and charge it.
