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 pedestriansAnd so on.
2, this depends on personal use habits! It's all about personal subjective consciousness! This issue to no good debate, I think wireless charging is very convenient, perhaps I am a lazy person, do not like the action of the plug, put on to hear the charging prompt tone do not care about it, more convenient.
3, "Electric vehicle wireless charging system Part 2: Communication protocol between Vehicle charger and charging equipment" (GB/T 38772), "Electric vehicle wireless charging System Part 3: Special requirements" (GB/T 38773),"Electric vehicle wireless charging system Part 4: Electromagnetic environmental limits and test methods" (GB/T 38774) a total of 4 national standards.
4, intuitively, the car wireless charging is short of a charging head insertion action; At a deep level, it has more advantages in charging flexibility, and even in the later stage, it can get rid of the limitations of a pile and a car to achieve a multi-car charging. Second, safety. The safety of automobile wireless charging technology is relatively high, there is no exposed connector, to avoid leakage, electricity and other safety hazards, do not worry about "charging with life".
5Many mobile phones have begun to be equipped with wireless charging function, and the car must be equipped with corresponding functions to the owner. Now the new models have slowly begun to be equipped with mobile phone wireless charging device, the front installation is not equipped with can choose to modify the nine-speed special car special car wireless charging device.
6. Maximum power. As of December 1, 2022, the maximum power of wireless charging of cars is only 15 watts, in order to charge cars more quickly, so all use 15-watt chargers. Wireless charging comes from radio energy transmission technology, which can be divided into two ways: low-power wireless charging and high-power wireless charging.
1, model highlights Wireless fast charging car : Chery new energy's first pure electric medium-sized SUV, the @LIFE platform is being developed, all-aluminum body, the whole NEDC range is 510 kilometers This year is Chery's product year, not only listed fuel vehicles, new energy models are also emerging in endlessly. Chery Ant, just listed yesterday, the new car is positioned as a pure electric medium-sized SUV, and a total of four models are launched, with a subsidized price range of 198-1.98 million yuan.
2, different from small ants, the positioning of more high-end ants is from all aspects of Chery new energy so far the most powerful products, no one. In terms of pricing, the official price of Chery Ant is 198-1.98 million yuan, there is no doubt that this price is not only a breakthrough for their brand itself, but also a direct confrontation with a large number of same-level pure electric SUVs on the market.
3, the price range of zero run C11 is 198-2.98 million yuan, including the extended range versionThe purchase threshold is 1.98 million yuan, and the pure electric version is 1.58 million yuan. Compared with mid-size SUVs on the market, the Zero Run C11 has a significant price advantage. In addition, the Zero Run C11 can provide front double-fork rear five-link suspension in the price range of less than 200,000 yuan, and the configuration of the vehicle is also very rich.
4. The new model of Dongfeng Fengshen E70 is matched with a permanent magnet synchronous drive motor with a maximum output power of 110 kW and a peak torque of 210 nm. At the same time, the car is equipped with a standard capacity of 446 KWH lithium iron phosphate battery pack, CLTC pure electric range of 401km.
1, Dongfeng Nano 01 as the first model of Dongfeng Nano, in the power, design, intelligence, safety and other aspects of the vehicle strength armed to the teeth, and through the "half level higher than the same level" of the core performance, pull up the pure electric model of the quality and price ratio.
2, and nano 01 is a good balance of this contradiction, Dongfeng quantum architecture No. 3 platform for its smart body to bring a variety of comfortSpace-friendly, with a perfect balance between body size and space comfort. As the original pure tram nano 01, so that the 4030mm length has A 2660mm long wheelbase that is not inferior to the A-class car, the effective space in the car is 2685mm, and the "room acquisition rate" is as high as 67%, which has significant advantages in the same class.
3, nano 01's biggest competitor is no doubt BYD Seagulls, in addition, the market hot zero run T03 is also a more direct competitor model of this car. In the comparison of these three models, the sizes from large to small are nano 0 Seagull and T03. Nano 01 and SeagullCompared with the two, the starting price of the two is very similar, only a difference of 1000 yuan, but seagull has a obvious disadvantage compared with nano 01 in terms of body size or wheelbase.
4, Dongfeng Nano 01 has just been listed on January 7, the official guide price is 480,000 to 480,000 yuan. Dongfeng Nano 01 is the first model of Dongfeng Nano, based on the Dongfeng Quantum architecture No. 3 platform, focusing on fashion design, flexible space, high intelligence and other selling points, so that low-cost pure trams can also have a leap-over car experience.
5, today (January 7), Dongfeng Nano brand new carNano 01 officially launched, the new car launched a total of 6 models, the price range of 480-480,000 yuan, and now there are 99 yuan under the order, deduction of 3,000 yuan concessions, the actual entry price of Seagull (from 380,000 yuan) is also cheaper. As a new model dedicated to benefiting more consumers with high-quality products with low thresholds, what is the Nano 01 really like? Below with circle brother to understand.
6, indeed, the ultra-low use cost and better driving quality brought by pure electric drive are more suitable as a supplement for family daily travel compared with traditional fuel small cars.
The logic behind the wireless charging technology applied by the German WIFERION, which was acquired by Tesla, in the modified Model 3 is 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.
First, Tesla cars use wireless charging technologyIs 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.
The charging process of Tesla takes about 12 hours, but when using a home charger, the voltage may drop due to the peak load of the transformer, which affects the charging speed. To increase efficiency, it is recommended to install a special wall-mounted charger, which will reduce the charging time to about 9 hours. Optional built-in dual chargers are availableThe charging cycle is further shortened, with a full charge taking approximately 4 hours.
For example, the commonly used charging pile fast charging power is generally more than 60kw, and the minimum slow charging power is also more than 7kw, so the current wireless charging of electric vehicles only looks good, but the practical value is not high. In fact, compared with the fixed wireless charging technology, the charging technology of the car on the road is the most worthy of expectation. According to WiTricity's website, the company's wireless charging technology can achieve charging efficiency and speed close to that of conventional home charging stations, and it will charge from the grid to the battery with an efficiency of 90% to 93%; Charging power will be able to reach 6-11kW, or even higher; The working distance between the ground transmitter and the receiving end of the vehicle can reach 10-25 cm, and most of the pure electric sports cars, cars and urban SUVs can be normally adapted.
