Has Type-C interface and PD protocol. The principle of Type-C to DC decoy is based on Type-C interface and PD protocol. Type-c interface is a new Type of USB interface, which has the characteristics of bidirectional transmission, fast charging and multi-device compatibility. It supports several protocols, including the PD protocol, for fast charging and data transfer.
pd to dc is the meaning of power port conversion. dc refers to direct current, is the size and direction of the constant direct current, the size (voltage level) and direction (positive and negative) do not change with time (relative range). pd refers to the pupil distance, which refers to the distance between the pupil centers of the two eyes, or the distance between the pupil centers when the two eyes are facing forward and the vision is parallel.
In addition, the DC protocol can also provide more security protection functions, such as overheat protection, overcurrent protection and overvoltage protection. The DC protocol supports a variety of Charging methods, including USB Type-C, USB PD (Power Delivery), and USB BC (Battery Charging). These charging methods can be selected according to different device types and needs to achieve the mostGood charging effect.

1, in order to fast charge dc wireless fast charge , first of all, the battery must be strong: High current charging dc wireless fast charging , the battery does not heat, the battery dc wireless fast charging Good heat dissipation performance dc wireless fast charging ; Chargers and charging cables can provide high current. Chargers and charging cables are relatively easy to solve. The technology and materials of the battery are difficult to solve.
2, the principle of fast charging is to store DC directly into the battery. Most of the DC charging method dc wireless fast charge , the output voltage is mostly three-phase four-wire ± The current fast charge principle on the market is to store DC directly into the battery, most of the DC charging method will be used, the output voltage is mostly three-phase four-wire ± The current market support fast charge pure electric vehiclesMost of them need to be fully charged in about two hours.
3, DC is a DC symbol, charging is the use of direct current, so DC is the meaning of charging. The national electrical symbol identification regulations: AC means alternating current, DC means direct current. On household appliances, AC is usually used to represent the AC input or connection of the appliance, and DC represents the DC output or input of the appliance. Charging is a Chinese term referring to the process of replenishing a device such as a battery.
4, generally AC will be fast, AC power capacity is large, DC will be limited by DC power capacity. AC charging mode: U is not consideredThe SB port has a current limit of 500mA, and uses the maximum current of the AC adapter for fast, such as 2A. Content: It is usually judged by detecting the Data /Data- short circuit of the USB port, and D/D-short circuit (internal implementation of the original charger) can be quickly charged.
The DC on the mobile phone represents direct current, also known as "constant current", constant current is a kind of direct current, is the size and direction of the same direct current. Constant current means that neither the magnitude (high or low voltage) nor the direction (positive or negative electrode) change with time (relative range). AC stands for alternating current.
AC stands for "alternating current", alternating current is also known as "alternating current", referred to as "AC". The current whose strength and direction change periodically with time is called alternating current, or alternating current for short. The current direction changes periodically from time to time for alternating current. China usually uses alternating current, the general frequency is 50Hz. Our common electric lights, motors, etc., use alternating current. In practice, alternating current is represented by the symbol "~".
AC stands for alternating current and DC stands for direct current. Alternating current and direct current are the two main forms of power transmission and use. In everyday electronic devices, we often encounter these two types of current conversion requirements. Especially in the application of chargers, it often involves the conversion of AC to DC.
In simple terms, ac stands for alternating current, which is the electrical energy we normally get from the grid, while dc stands for direct current, which is the stable voltage needed for batteries or electronic devices. The function of this adapter is to convert alternating current (input: 110 volts, 60 Hertz) to direct current (output: 6 volts, 450 mah) in order to provide the required power to the device.
AC is the English abbreviation of AC power supply, DC is the English abbreviation of DC power supply. AC/DC power supply is a power converter with AC input and DC output.
1, in the pursuit of high-efficiency charging methods, fast charging technology stands out. Among them, DC fast charging (DC fast charging) with high voltage and high current characteristics, can quickly fill the battery in tens of minutes, and its charging speedThe iteration of technology continues to improve. AC Fast charging (AC fast charging) technology enables a fast and convenient charging experience with the right equipment. In addition to fast charging, other strategies also help improve charging efficiency.
2, you want to ask what is the fastest way to charge new energy vehicles? It uses fast charging technology. There are two most commonly used fast charging technologies: one is DC fast charging (DC fast charging) technology, and the other is AC fast charging (AC fast charging) technology.
3, so, for the current four ways of charging new energy vehicles, how much do you know? Which is more suitableWhere's your car? NO.1 Direct current: Fast charge The preferred charging principle converts AC current into DC power through the charging pile to charge the power battery. Dc charging efficiency is high, DC charging pile power on the market ranges from 30 to 120 kilowatts, generally 0.5-1 hours can be full.
4, the use of public charging pile charging is faster, but need to go to the special charging area for charging, in the place without public charging pile is not very convenient. Charging with a home charging device: Charging with a home charging device is safer and costs less. But the charging speedSlower than laughter, a charge generally takes 8-10 hours.
5, although the way of fast charging is very fast, but in the charging process, it is easy to lead to the increase of battery heat, a strong chemical reaction inside, which has a certain impact on battery life, which will lead to an increase in later maintenance costs. The third, new energy vehicles in the daily driving process, we must ensure that the battery has enough power, the best driving range of new energy vehicles is 1/3~2/3, if every day to 20 kilometers, at this time the new energy vehicle is best for 2 to 3 days a charge.
