To about 8 days. Solar surveillance camera standby time if it is rainy or cloudy, the standby time is not 4 days, because in the standby four days, the solar panel has been charging the battery during the day, but it does not charge at night, so the standbyThere is still 30-40% of the conversion to charge, so the actual standby time is about 7 to 8 days, and the power will have an impact.
Hello! How much solar panels generate electricity depends on the power of solar panels and weather conditions, the longer the light time, the higher the illuminance, the more power generation. 150W photovoltaic panel to meet the electricity of a camera is no problem.
Photovoltaic solar panels are generally manufactured in the form of modules, usually with 30V or 18V output, to see the nominal voltage value on the factory label to determine. If used for surveillance cameras, the corresponding constant voltage can be matchedRoad and battery to obtain a stable voltage (at night will use battery power supply).
You can't shoot where the camera lens is not pointed; If the camera is already working, it is not possible to manually control it, and it is generally set a preset bit and then intelligent cruise.
Temporary solar traffic lights will, of course, take photos. And it's still a high-definition camera, so it can clearly take pictures of you no matter what the weather. That's why we all need to watch when we cross the intersection. Don't run the yellow light. The intersection is difficult. It's better to be three minutes slow than to steal a second. Sometimes pedestrians and non-motorized vehicles suddenly appear. The totalStreet mobile phone wireless charging street lights, what is going on?
Mobile phone wireless charging street lights appear on the streets of Wuhan, and mobile phones have wireless charging functions, which can be charged directly next to the corresponding street lights. This is a new street lamp installed on Jianghan Road in Wuhan City, which can solve the problem of people being unable to charge outside. Personally feel this function is very convenient, they can charge when waiting for people on the street or urgent use of mobile phones. Just be careful when charging to avoid having your phone stolen.
is free and open. According to media reports, there are many Wuhan citizens walking in the Jianghan Road pedestrian street, inStreet lights that can charge mobile phones wirelessly have been discovered. These transformed landscape street lights are somewhat different from ordinary street lights, and the logo of "mobile phone wireless charging port" can be seen on the base of the lamp post, and the wireless charging coil is added, there are obvious traces of transformation, and it is very recognizable.
Charging lines for mobile phones will be withdrawn from the market stage in the future, because even the streets of Wuhan have unlimited charging street lights, everything is possible. The appearance of this wireless charging street light on the streets of Wuhan has also caused intense discussion among everyone, and those citizens have found themselvesWhen I was walking in the evening, I found this street lamp that can be charged, which is obviously very interesting.
Wireless charging is actually an electromagnetic induction charging method, the advantage of this charging method is that the cost is relatively low, and the efficiency is very high. The specific working principle is that the coil is installed on the charging base and the coil is also installed on the back of the mobile phone. When the mobile phone is near the charging base, the magnetic field of the coil will change. After the magnetic field changes, the induced current will be generated and the magnetic energy will be converted into electrical energy to complete the wireless charging process.
Yes, a few days ago, a "Wuhan street mobile phone wireless charging street lamp" causedPay attention. It is reported that when walking on Wuhan Jianghan Road recently, I found that there was a "mobile phone wireless charging port" sign on the base of the street landscape street lamp post, which attracted many citizens to stop and watch.
Yes. In November 2020, a large number of street lights that can charge mobile phones wirelessly appeared on Jianghan Road in Wuhan, and many citizens who came to shop here have tried them, and the relevant topic has triggered heated discussion among netizens. According to the staff of Wuhan Construction Bureau, about 60 mobile phones with wireless charging function of new street lamps have been installed on Jianghan Road, and fast charging can be achieved on the road light pole marked with "mobile phone wireless charging port". Each street lamp has two functionsCharging, but there are requirements for the phone model.
Can electric vehicles in the future be like mobile phones photovoltaic wireless charging to achieve wireless charging? Of course you can! Don't talk about the future. It's already here. BMW produces photovoltaic wireless charging electric vehicles, which can already be charged wirelessly. As long as the driver puts the car on the wireless chargerThe system will automatically charge the car. A domestic electric vehicle company is also studying wireless charging technology, which has entered the experimental stage and may be mass-produced in the near future. At present, only static wireless charging can be achieved, but static wireless charging is only a little more convenient than wired charging, and it is far less than wired charging in terms of cost, safety and charging efficiency. In terms of technology and cost control, dynamic wireless charging is difficult to popularize in a short time. The reason why there are few models of electric vehicles that support wireless charging now is that static wireless charging is the fundamental reasonThe practicability is poor.
To answer this question, we need to start from the development of wireless charging and its principle. In the 1830s, Michael Faraday discovered that changes in the surrounding magnetic field would create an electric current in the wire. In the 1890s, Nikola Tesla, an assistant to Edison's spectral radiation research project, proposed the idea of wireless power transmission.
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. And 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.
1, each has its own advantages: wireless charging is convenient, do not need to connect the phone to the charger, put on the charging board; Wired charging is more stable, and the charging speed is faster than wireless charging.
2, wireless charging good. Wireless charging does not require direct contact between the charger and the device being charged, making it easy to useStrong environmental adaptability, avoiding the physical interface so there will be no interface wear, sparks, leakage and other problems, in addition to wireless charging can also achieve high voltage, high current, high power charging. The cable is charged. Wireless charging also requires a wired charger, but also more wireless charging board.
3, the pursuit of higher portability and comfort, you can choose wireless charging; In pursuit of faster charging speed and wider application range, you can choose wired charging. The advantage of wireless charging is that it provides higher portability, which is especially suitable for wearable devices, smart home and other fields. However, the charging speed of wireless charging is relatively slowAnd the distance between the charger and the device will affect the charging effect.
4, wireless charging is better. The convenience of wireless charging Wireless charging provides users with great convenience. For example, some public places, such as cafes, restaurants and airports, offer wireless charging services where users simply place their phones on the charging mat without carrying additional charging cables. In addition, wireless charging technology is also being applied to furniture and cars, allowing users to charge at any time at home and in the car.
5, the following will introduce the difference between the two charging methods in detail. Advantages and disadvantages of wired charging and wireless charging Wired chargingThe advantages of electricity are fast charging speed, good stability, and data transmission can also be carried out at the same time. The disadvantage is that the connection line is required and the use is not convenient enough. The advantage of wireless charging is that it is easy to use, does not require a cable, and only needs to put the device on the charging base to charge.
6, convenience: when the phone is charging, the phone comes in, but it is not convenient to answer in some specific situations. At this time, the convenience of wireless chargers is reflected. Simply pick up the charging case and move it to any place where the user can easily answer the phone.
1, it is free and open. According to media reports, many Wuhan citizens took a walk on Jianghan Road and accidentally found street lights that could charge mobile phones wirelessly. These transformed landscape street lights are somewhat different from ordinary street lights, and the logo of "mobile phone wireless charging port" can be seen on the base of the lamp post, and the wireless charging coil is added, there are obvious traces of transformation, and it is very recognizable.
2. According to the Wuhan Construction Bureau, there are 60 on Jianghan RoadMultiple of these high-tech street lights. Each street lamp is equipped with two wireless charging ports, which support high-power fast charging and are open to the public free of charge. However, only phones with wireless charging will be able to use the service. The staff reminds that since these charging street lights are unattended, citizens should take good care of their personal property when using them to prevent theft. Citizens who have experienced this service generally give positive comments.
3, Wuhan street mobile phone wireless charging street lights are free, passers-by walk past, put the mobile phone can be charged, very convenient.
4, the staff of the Wuhan Construction Bureau explained,Wuhan Jianghan Road has more than 60 such landscape street lights, each street light has 2 charging ports, are high-power wireless fast charging, free for the public, but only the mobile phone with wireless charging function can be used.
5, Wuhan street added a new convenient service, that is, mobile phone wireless charging street lights, surprisingly, this service is free. Just place the mobile phone gently on the street light, you can start charging, for those who are out of mobile phone power, is undoubtedly a big boon.
Can electric vehicles achieve wireless charging in the future like mobile phones? Of course you can! Don't talk about the future. It's already here. The electric cars produced by BMW can already be charged wirelessly. As soon as the driver drives over the wireless charger, the system automatically charges the car. A domestic electric vehicle company is also studying wireless charging technology, which has entered the experimental stage and may be mass-produced in the near future.
Then, if the car can also be charged wirelessly, that is, stop and charge, or even runSide charge, so not to solve the electric car now a major pain point? Recently, the Ministry of Industry and Information Technology issued regulations to raise the charging power limit of mobile phones and other mobile devices to 80W, and apply wireless charging technology to electric vehicles. This means that the era of wireless charging for electric vehicles may be coming.
It is worth mentioning that the "Interim Provisions for Wireless Charging (Power transmission) equipment radio Management" issued by the Ministry of Industry and Information Technology recently clearly raised the charging power limit of mobile phones and other mobile devices to 80W, and stipulated that the management provisions also apply to the wireless charging of electric vehicles. This undoubtedly injected into the development of wireless charging technology for electric vehiclesNew motivation. In short, electric vehicle wireless charging technology still faces many challenges, but its development prospects are broad.
Future charging methods will be more intelligent, such as wireless charging or charging pad, the vehicle does not need to carry a charger, just gently placed on the charging pad, you can automatically start charging. This way can not only improve the charging efficiency, but also optimize the vehicle structure, improve performance and endurance. Therefore, future electric vehicles are highly likely to adopt this more intelligent charging method to better cater to user needs.
German automaker BMW has demonstrated a car wireless chargingThe board, the owner can place it on the floor of the garage. When the car is parked and turned off, the charging pad automatically begins to charge the car. Porsche Charging Park cannot yet guarantee that wireless charging will be ubiquitous or adopted on a large scale in the future.
