Today to share the knowledge of wireless car charging, which will also be wireless car charging which brand is good to explain, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Anker: Anker car charger quality is relatively stable, can charge two devices at the same time, chip quality is excellent and good protection design, but also has a good warranty andAfter-sales service. AUKEY: AUKEY car chargers mainly consider quality and beautiful appearance, high power conversion efficiency, provide safe and stable power for multiple devices, and also have intelligent functions such as automatic identification of adaptive equipment power.
PHILIPS (PHILIPS) small and beautiful, exquisite workmanship, full metal shell, full metal material, looks very texture, plug into the car, there will be a circle of white light belt, and then charging speed, my iPhone, plug in charging speed is very fast.
Car charger recommended brand: the first Pinsheng Guangdong Pinsheng electronic sharesLimited company second Momis Shenzhen Momis Co., LTD. Third Belkin Belkin Trading Co., LTD. Fourth first section fifth Philips sixth green link using car charger will make the car lose electricity? Normally, as long as you do not charge for a long time, the problem is not big, especially the new car battery, and the car is turned off after a long time to charge, so there is basically no problem.
Yingcai Star Yingcai star is the product brand of Chenghai District Yingcai electrical Appliance factory, Shantou Chenghai District Yingcai Electrical Appliance Factory, brand Yingcai Star HSC, located in Dongli town, Chenghai District, Shantou City, the main production of automotive electronic productsProducts, such as car home charger, car apple charger, car oxygen bar charger, car smart electric cup, etc., product quality is stable, fine work, novel appearance.
Huawei Car Charger QuickCharge Fast Charge (Max 18W) If the mobile phone you are using is a mainstream Android phone or supports fast charge iPhone, it is recommended that you choose Huawei car charger QuickCharge Fast Charge (Max 18W). The car charger has two USB ports, one of which supports 9V / 2A 18W fast charge, covering the current mainstream handThe fast charge requirement of the machine.
Car charger recommended Newman, modern and Oshur these brands, easy to install to the car, the price is not expensive, it is recommended. Newman this model is priced at about 20 yuan, the first glance looks good color and the holder feels very good, exquisite workmanship, relatively light weight, it is very stable after being installed in the car, the mobile phone can be automatically tightened and will not shake randomly, in order to use convenience, it can automatically adjust the Angle and height.
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. Standard tests use iPhThe one 11 pro comes with all wireless charging phone stands, and the rule is that the phone stays lit, and the time required to charge 10% (from 40% to 50% of the phone's battery) is tested 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, it is applied to electric vehiclesThe development of wireless charging technology is not as good as expected. 4, the vehicle only needs 10 seconds to accelerate 100 kilometers, the top speed is 140 kilometers per hour, and the mileage can reach about 389 kilometers in the WLTP test mode, which is 30% more than the endurance 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, while the Geely Galaxy L6 masterWhen physical wires are connected, electric devices are charged by means of electromagnetic fields or electromagnetic waves.
The breakthrough of the technology is to find a way to "catch" electromagnetic waves, that is, to use the "resonance" principle of physics - two objects with the same vibration frequency can efficiently transmit energy. The system consists of the main circuit located outside the car and the secondary circuit, rectifier and drive system located inside the car.
The basic principle of wireless charging: electromagnetic induction type: the primary coil of a certain frequency of alternating current, through electromagnetic induction in the secondary coil to produce a certain currentTo transfer energy from the transmitting end to the receiving end.
Wireless charging system mainly adopts the principle of electromagnetic induction. Wireless charging usually adopts electromagnetic induction, energy coupling through the coil to achieve energy transfer. When the system works, the input end converts the AC mains into direct current through the full bridge rectifier circuit, or uses the 24V direct current end to supply power to the system directly. After passing through the power management module, the output direct current is converted into high-frequency alternating current through the 2M active crystal oscillator inverter to supply the primary winding.
The principle of wireless charging of cars is to convert electrical energy into electromagnetic waves, and then sent to the receiver, and then the electromagnetic wavesConverted into electricity. 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.
This is the end of the introduction of wireless car charging and wireless car charging which brand is good, do not know you find the information you need? If you want to know more about this, remember to follow this site. < / p >
