For example, Tesla models turn on FSD to automatically recharge the vehicle after arriving at the destination; Unmanned buses, express vehicles, etc., can also be completely unmanned management; Or tram wireless charging goodWhen you do not have time to find a charging pile for your car, you can send the vehicle to find its own wireless charging pile "foraging"; Wireless charging can also solve the problem that many vehicle charging plugs are not shared at present, just like mobile phones, cars, SUVs, trucks and other different types of different brands of vehicles can use the same charging plate.
First of all, Tesla's wireless charging technology uses the principle of electromagnetic induction. The technology transmits energy through special electromagnetic fields, allowing Tesla cars to charge themselves when parked. This technique is not only efficient, it can also be greatly reducedCharging time. Secondly, the wireless charging technology of Tesla cars also has the characteristics of intelligence.
According to media reports, Tesla recently launched a $300 "wireless charging platform" that can charge up to 3 devices at the same time. This wireless charging pad can provide up to 15 watts of charging power for each device that supports the Qi wireless charging protocol, including iPhone, Android or AirPods headphones. According to Tesla's official website, this charging pad has been opened for pre-sale, and willIt will begin shipping in February 2023.
Magnetic resonance is an efficient and safe wireless charging method. It generates magnetic field resonance through the resonator 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, wireless charging technology is showing broad development prospects, is expected to become the mainstream of electric vehicle charging.
Tesla's charging process takes about 12 hours or so, but when using a home charger, due to transformer load peaks may causeThe voltage drops, 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. The optional dual built-in charger can further shorten the charging cycle, and it only takes about 4 hours to full charge. 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 be able to charge from the grid to the battery with an efficiency of 90 to 93 percent. Charging power will be able to reach 6-11kW, or even higher; Its ground launch end is connected with the vehicleThe convenience of car charging needs to be improved, and the government, enterprises and society need to work together to increase investment, promote infrastructure construction, and improve the coverage and utilization rate of charging facilities in order to better meet the needs of users.
With the continuous popularity of new energy vehicles, including the national power grid, including the major operators have begun to lay down, Oems and some shared travel service providers have also begun to lay out infrastructure, although there are still some problems have not been solved, but new energy vehicles will be the mainstream trend of future cars.1, the new energy vehicle can be unplugged midway. The following is a relevant introduction to the charging of new energy vehicles: The correct way to unplug: First turn off the charging gun. Some charging guns will be powered off by swiping the card, scanning the bar code, entering the password, unplugging the power, etc. Please wait a moment after the power is turned off and then pull the charging gun out of the jack of the car. Note for charging: Before charging, it is necessary to confirm whether the state of the car is good or not.
2, the new energy vehicle is not fully charged can be unplugged, if the electric vehicle is not full of unplugged, with a chargeIt will also speed up the speed of battery water loss, and long-term operation will also cause the battery to fill the drum phenomenon, affecting the battery life. Once the battery is filled, it will be an irreversible situation, basically irreparable, and you can only choose to replace the new battery.
3, new energy vehicles can not be disconnected in the middle of charging. There are a variety of problems that cause the charging of new energy vehicles to stop for a while: There is a problem with the battery of new energy vehicles. The battery cannot be charged because the temperature is too low. There is a problem with the connection of the charging cable. The charging mechanism used is faulty, the charging pile is damaged or the power supply is faulty. <4, in the charging process of new energy vehicles, users can unplug the charging gun. However, it is important to note that this operation must be done carefully to avoid possible safety hazards. First, before unplugging the charging gun, you need to turn off the charging device. Depending on the specific charging device, the shutdown method may vary, and may need to be carried out by swiping the card, scanning the barcode, entering the password, or unplugging the power directly.
