The difference and principle between AC charging gun and DC charging gun
With the continuous growth of new energy vehicle sales, the development of the charging gun industry has been further promoted. According to statistics, in 2023, my country's new energy sales will reach 9.495 million vehicles, with a market share of 31.6%. As an important supporting facility for electric cars, the market demand for charging guns is also growing. To meet market demand, charging gun companies are constantly investing in research and development to improve product quality and technical level.
AC charging guns AC (Alternating Current) and DC charging guns DC (direct current) are two major categories of products in the charging gun market, each with its characteristics to meet everyone's charging needs in different scenarios. AC charging guns have been widely used in homes and commercial places due to their moderate charging speed and low cost. DC charging guns have become the first choice for new energy vehicle fast charging stations due to their fast charging and high power output.
01AC charging gun
AC charging guns are also commonly known as slow charging. This is because the AC voltage is small, the charging time and speed are slow, and it usually takes 8 to 10 hours to charge the battery using an AC charging gun fully. Such characteristics often meet the power needs of the family, so many names have been derived, such as home charging, on-board charging, slow charging, portable charging, etc. These names belong to the scope of AC charging guns.
Working principle: The AC charging gun needs to go through the steps of power connection, signal transmission, power conversion, and charging control during the charging process. It first inserts the plug into the power socket, then transmits the power signal to the charging interface of the electric vehicle into the electric vehicle, and then converts the AC power into DC power through the internal power conversion device to charge the battery of the electric vehicle.
Below are the standard socket numbers and styles of DC charging guns in different regions:
02 DC charging gun
DC charging guns are commonly known as fast charging. This is because the DC charging current and voltage are large, and the charging time and speed are relatively fast. DC charging guns can usually fully charge the battery within 30 minutes. Suitable for long-distance travel or urgent charging. Because of this feature, DC charging guns are more often equipped in places such as new energy Q car fast charging stations, suitable for occasions where the mileage needs to be quickly replenished.
Working principle: When DC charging, the DC pile itself converts the three-phase electricity of the power grid into DC electricity, and then transmits it directly to the battery pack in the electric vehicle for charging through the DC gun.
