1, in the process of charging new energy vehicles, if you need to unplug the charging gun halfway, it will not cause problems to the vehicle. However, it should be noted that after unplugging the charging gun, it can not continue to charge, and it is necessary to re-swipe the card or plug the gun to charge. The charging methods of new energy vehicles are mainly divided into three types: slow charging, fast charging and wireless charging.
2, there is no problem when pulling out the charging gun. But it can't be charged, so it needs to be charged. Source of energySlow charge: Suitable for car chargers and wall-mounted charging piles in the home. Its current and power are relatively small, the general charging time takes 6 to 8 hours; Fast charging: There are two forms of charging station and mobile charging trolley.
3, Can the new energy vehicle be unplugged midway? In the process of charging new energy vehicles, if you need to unplug the charging gun, there will not be too much problem. However, it should be noted that after unplugging the charging gun, it can not continue to charge, and it is necessary to re-charge the card. There are three ways to charge new energy vehicles: slow charging, fast charging and wireless charging.
4, in useWhen it comes to new energy vehicles, unplugging the charging gun midway will not affect the vehicle, but it can not continue to charge later, and it is necessary to re-operate the card and insert the gun. There are three main ways to charge new energy vehicles: slow charge: suitable for car chargers and family wall-mounted charging piles, its current and power is small, charging time is usually about 6-8 hours, suitable for daily use of energy.
The constant voltage charging method is used on the car, when the battery voltage reaches a certain value, the generator regulator will be cutCut the excitation current, below this value will be switched on to continue charging. The 12V battery is generally controlled at 12V, the 24V battery is controlled at 28V, and the charging method in the maintenance station is a special silicon rectifier power supply that can accurately control the charging voltage and flexibly adjust the charging current.
The constant voltage charging method is used on the car. When the battery voltage reaches a certain value, the generator regulator will cut off the excitation current below this value, and continue to charge. The 12V battery is generally controlled at 12V24V. The battery is controlled at about 28V. The charging method at the maintenance station is a special silicon rectifier power supply that can be accurately controlledThe electric voltage can be flexibly adjusted charging current.
The main charging method of the car is constant voltage charging and four main charging methods. Constant voltage charging means that when the battery voltage reaches a certain value, the generator regulator will cut off the excitation current, and when it is lower than this value, it will be switched on to maintain the charging state. The 12V battery is generally controlled at 12V, and the 24V battery is controlled at about 28V.
1. Charging speedSlow: Due to the current mobile phone and other receiving devices, most limit the input power, so the charging speed is slow. High cost: The charger needs to have an electronic circuit to push the coil, and the electrical device needs to have an electronic device to convert power, both also need to have a coil, and need a high-frequency filter circuit to meet FCC and other specifications, so the cost is higher than direct contact.
2, electromagnetic induction charging, very simple, and the principle of electromagnetic induction in high school is similar, wireless charging the charging base and the terminal are built with coils, so that the two are close to the charging seat and start to supply power from the charging seat to the terminal. A lot of wireless chargingMobile phones are the same principle, but the location must be relatively uniform in order to charge efficiently. And there is also coupling radiation problem, electromagnetic wave coupling will not exist a large magnetic field leakage. 3, there are four basic principles of wireless charging, respectively, electromagnetic induction charging, magnetic field resonance charging, radio wave charging, electric field coupling charging, the mainstream standards on the market mainly Qi standard, PMA standard, A4WP standard, iNPOFi technology and Wi-Po technology five. Let's take a look at the principle of wireless charging.
4, wireless charging methodThere are electromagnetic induction, magnetic resonance, electric field coupling and radio wave transmission, wireless charging of mobile phones mostly uses the principle of electromagnetic induction. Electromagnetic induction wireless charging, when the current of the power supply through the coil (wireless charger's power supply coil) will generate a magnetic field, other unenergized coil (mobile phone side of the electric coil) close to the magnetic field will generate current, charging the mobile phone.
5, static wireless charging Static wireless charging technology is to charge the car when the electric vehicle stops, according to its characteristics, usually suitable for shopping malls/residential parking lots and other occasions. Radio-energy transmission technology
