Power of new energy charging piles.

Power of new energy charging piles.

The power of new energy charging piles includes AC piles with 7kw and 14kw, and DC piles with 30kw, 60kw, 120kw, and 240kw, which can be divided into two categories: fast charging piles (DC charging piles) and slow charging piles (AC charging piles). It has protection functions such as leakage protection, short circuit protection, overcurrent, overvoltage, and undervoltage protection. Except for short circuit and leakage protection, other protection functions are achieved by controlling the contactor through the charging controller to achieve self recovery; Short circuit and leakage protection are implemented using miniature circuit breakers with leakage protection.

Power of new energy charging piles
Communication charging stations are generally 16A@220V （3.5kW）、 32A@220V （7kW）， These two specifications are more common and are aimed at general private passenger cars; 32A@380V （20kW）， 63A@380V （40kW）， Generally used for BYD E6 taxis, light buses, or other types of plug-in hybrid buses; 30kW@500V The 60kW@500V The 120kW@500V The latter two specifications are generally used for high-speed backbone network charging stations. Charging piles with higher voltage (750V) and the same power or higher power (180kW/240kW) are generally used for urban bus hub charging stations, large charging and swapping stations, and are aimed at large and medium-sized pure electric buses (6-meter, 8-meter, 10 meter, 12 meter or 18 meter).
 
For new energy electric vehicles, charging stations have the same significance as gasoline for traditional fuel vehicles. As the core requirement of new energy vehicles, charging stations are related to the vehicle's driving experience. According to the power of charging stations on the market, they are divided into DC charging stations and AC charging stations. Different types of charging stations naturally have different charging power for vehicles.
 
Home charging stations are divided into 7kw and 3.5kw, usually selected as household AC 220V single-phase power supply; The power is usually determined by the charging current. If the current passing through is 32A, it is a charging pile with a power of 7kw. If the current is 16A, the charging pile power is extremely 3.5kw. The actual charging is determined based on the charging parameters of the electric vehicle and the matching results of the charging pile.
 
The power of a DC pile is much higher than that of an AC pile, but the charging port of the DC pile is 9-hole, and the current is relatively large. The power is available in 30kw, 60kw, 120kw, 240kw, 380kw, and other power options. Generally, 30kw and 60kw are more commonly chosen for household use, such as hybrid cars with a battery capacity of 18 degrees. If charging takes 6 hours, it is about 3 degrees per hour.
