Only at this stage, the power of wireless charging is low, the charging speed is slow, the charging time is longer, and it can only be slowly charged, and it can not achieve fast charging, and the energy conversion efficiency is not as high as the plug-in charging efficiency. For example, BMW's wireless charging power is only 3kw, and the wireless charging scheme made by a domestic electric vehicle company can reach a maximum power of 11kw. Such charging power, compared with the current stage of the charging pile power, is still very low.
Tesla bought the German WIFERIONThe logic behind the wireless charging technology applied in the modified version of 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.
Is true. This way of charging is very fresh and convenient, but there are concerns about radiation. In this regard, the radiation of wireless charging technology is very small, far lower than the radiation of mobile phones, and the installation of the receiver will not affect the normal use of electric bicycles.
But the advantages of wireless charging are also very obvious. Since there is no need to plug and unplug the charging gun, the convenience of charging is significantly improved, and the risk of electric shock is reduced. More importantly, if dynamic wireless charging mode is deployed, it can greatly reduce the amount of battery power carried by electric vehicles, reduce the cost of the vehicle, and completely solve the user's driving range anxiety.
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 High-power wireless charging often uses harmonicVibratory (most electric vehicle charging uses this method) by the power supply device (charger) to transmit energy to the electric device, the device uses the received energy to charge the battery, and at the same time for its own operation. Overall, while the idea that electric cars will never have to be recharged again is appealing, it's still a beautiful vision given the current technology and market environment. We look forward to the development of technology in the future to bring more possibilities, but at present, charging is still an essential part of the use of electric vehicles.
Second, wireless charging technology wants to be truly popularThere are also high requirements for the precise positioning and intelligence of vehicles. Only when the vehicle is precisely parked in the charging space can the ground system establish a channel with the vehicle's on-board system and achieve charging. In the case of precise positioning, the same footprint, the number of electric vehicles using wireless charging compared with the traditional charging pile charging will be greatly increased, greatly improving the space utilization and charging efficiency.
To achieve efficient energy transmission. The advantages of this method include high efficiency, long distance transmission and security, but the technical requirements are high, the cost is relatively high, and it has not been applied on a large scale. In general, wirelessCharging technology is showing broad development prospects, is expected to become the mainstream of electric vehicle charging. However, technical difficulties and cost issues are still the key issues that need to be solved, which requires continuous innovation and improvement by researchers.
At present, electric vehicles mainly rely on fixed-position charging piles for battery charging, but wireless charging is their general direction of development. If wireless charging can achieve an increase in power and speed, it should be a more perfect charging method for new energy vehicles. The operation is simple, convenient to use, and there is no danger of electric shock, but this application technology still needs time to develop, and ordinary people are difficult to enjoy this service in a short time.
The research and development of automotive wireless charging technology is a highlight of the current industry. As a technology leader, this new initiative by Qualcomm will undoubtedly promote the progress of the industry.After 24 months, it is reasonable to expect more cars equipped with Qualcomm wireless charging technology to enter the market. Despite the promising prospects of dynamic wireless charging, static charging still dominates. However, as the technology matures, wireless charging is expected to become the mainstream choice for car charging.
For pure trams, the most reliable solution now is electromagnetic induction, which is more stable and reliable. 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 future)Car rules the development direction of wireless charging).
At the same time, the development of fast charging and wireless charging technology has brought revolutionary improvements to the charging speed and convenience of electric vehicles. In terms of intelligence, new energy vehicles are gradually achieving higher levels of autonomous driving functions. By equipped with more sensors and computers, as well as the application of artificial intelligence, machine learning and other technologies, new energy vehicles can improve the safety and comfort of driving, and reduce driver fatigue and errors.1, ringEnvironmental inspection: Please ensure that the AP61 wireless charger is located in a well-ventilated environment without any shelter. Confined Spaces can cause heat to build up, causing heating problems. Original Adapter Use: Make sure you are using the original adapter for the AP61 wireless charger. The use of non-original or low-quality adapters may cause electrical instability, which can lead to equipment overload and heating.
2, please check whether the back center of the phone is placed in the center of the wireless charging board. When there are inclusions between the mobile phone and the wireless charging pad, it may not be able to charge normally. Please check the back of the phone. If the protective phone case used is too thickWill hinder wireless charging, it is recommended to remove the phone cover to try to recharge. Please use the original charger. If you use a non-original charger, you may not be able to charge normally.
3, indicating that it is charging: When the green light on the Xiaomi wireless charger starts to flash, it usually means that the charger is charging the device. This is a standard charging indication that the charger has been properly connected and is transmitting power. Possible problems or anomalies: However, a flashing green light may also indicate that some problem or anomaly has been encountered during charging.
4, the charger problem: if you useIf it is a wireless charger, it may be that the charger itself has problems, such as the charger power cord is loose, the charger interface is dirty, the charger heats up, etc., which may lead to wireless charging instability. Mobile phone problems: If your mobile phone has problems such as poor contact of the charging port and loose charging cable, it may lead to unstable wireless charging.
5, efficiency problem Wireless charging is subject to the development of technology, charging efficiency is still relatively poor, because the power of wireless charging itself is small, and the actual performance is not stable.
