1, if you can transmit power over a longer distance, and can transmit more power, here to talk about another medium range wireless charging technology, can be longer distanceElectromagnetic resonance technology for energy transmission. Its advantage is that the transmission distance is much greater than the electromagnetic induction, can carry out more than 10cm electromagnetic induction energy transmission, even in the larger distance of the transmission distance, the transmission power can still reach several kilowatts. 2, not only Japan, there are many countries are studying wireless charging road, at the end of last year, the world's fourth largest automobile manufacturer Stellantis announced on the official website, their innovative dynamic induction charging technology after years of research and months of testing proved successful, for car wireless charging test road Arena del Futuro is officially opened. So now wireless charging technology is also a very hot ranks.
3, electric vehicle wireless charging technology mainly uses the mutual inductance in the law of electromagnetic induction. It is also similar to a transformer, which inputs from the primary coil and then generates an induced current on the secondary coil. It mainly relies on the energy transmission between electricity and electricity, converts electricity into magnetism, and then induces electricity. Wireless charging is simply to charge electrical equipment through electromagnetic fields or electromagnetic waves without being connected by physical wires.
4, for pure electric cars, now more reliableThe scheme is still electromagnetic induction, which wins in stability and reliability. Although magnetic resonance can have a higher power distance advantage (a few centimeters to a few meters), it is difficult to control, technical difficulty is high, and it is not easy to use for electric vehicles (this may be the development direction of wireless charging in the future).
5. The electric vehicle wireless charging technology transmits electric energy in the form of high-frequency alternating magnetic field through the power supply guide rail buried under the ground to the electric energy picking mechanism running in a certain range of the vehicle receiving end, and then supplies power to the vehicle energy storage equipment. When charging begins, the power transmitter PTx generates an alternating current through its coils, which in turn generates an alternating magnetic field according to Faraday's law.
6, the wireless charging principle of the car is to convert electrical energy into electromagnetic waves, and then sent to the receiver, and then convert electromagnetic waves into electrical energy. Charging technology is not complex, mainly the use of electromagnetic induction and magnetic resonance, but the biggest difficulty of wireless charging is that the lack of a unified standard, charging time is too long, efficiency is too low, high cost.
First, wireless chargingAlso known as inductive charging, its biggest advantage is safety. Even in harsh weather conditions, such as rain and snow, there is no risk of electric shock. 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.
When charging on the highway, it is necessary to pay attention to the following points: First, to choose a charging pile that meets national standards to ensure charging efficiency and safety. Secondly, to comply with the charging rules, do not use non-standard charging cables when chargingCable or charger. Finally, check the charging device regularly to ensure its normal operation. If you find anything abnormal, stop charging immediately and contact a professional for repair.
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, when charging with a public charging pile, the fast charge can be used, and the vehicle can be fully charged within 1-2 hours, without delaying the carDrive normally.
First drive to the high-speed service station. Then drive to the charging pile near. Finally, it will pay a fee to check the plug on the car to complete the operation of charging the temporary license plate new energy vehicle on the highway.
Fourth, if there is only less than 5% of the electricity left in the service area, and there is no charging pile available in the service area, and you do not want to call an emergency rescue, you can consider charging with a portable charging gun. All trams can be charged by ordinary household AC, and the manufacturer will send such a charging gun when buying a car.
Electric cars run long distances on high speeds, in addition to travelIn addition to the preparation of the plan before, in addition to try to control the speed of the vehicle, a long time deep step on the switch at high speed will consume electricity very fast, should try to maintain the speed of 90km/h, which can reduce the power consumption as much as possible.
How to wireless charging the car wireless charging How to use the car wireless charging method is: the car wireless charging is fixed in the appropriate position in the cab; Connect one end of the USB data cable of the wireless charger to the car cigarette port and the other end of the chainConnect to 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. The owner needs to buy a suitable wireless charger equipment, and then fix the wireless charger on the vehicle, and the fixed position should be convenient for the owner to takeTake. 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 point, and connect the other end to wireless chargingA surname Make sure the connection is secure and does not come loose or break.
Install wireless charger. First, choose the right wireless charger for your vehicle, and install it in the right place in the car, ensuring that the location is easy for you to access when using. Connect the power supply. Connect the USB interface of the wireless charger to the cigarette lighter interface of the vehicle to ensure that the data line is firm and the power supply is stable. Place your phone to charge. Place your phone in the sensing area of the wireless charger.
1, electric vehicle wireless charging technology has become a hot electric vehicle to become the mainstream, the problem of battery life has not stopped, in solving the battery life problem, the various car companies are also trying their best to find a way to solve this problem, in addition to the power and fast charge, in fact, there is a different way, that is, road charging, Let the car run along the road.
2, Tesla acquired the German WIFERION, in the modified version of the Model 3 applied wireless charging technology, the logic behind is electromagnetic induction wireless charging. The Tesla that we're currently using for modificationModel 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.
3, wireless charging process will definitely heat. 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.
