The Role Of Electric Car Charging Gun

- Nov 06, 2018-

As a charging connector for electric vehicles, the charging gun is a "bridge" connecting charging piles and electric vehicles, and is also an important component for interconnecting charging facilities and electric vehicles.


The rise and development of the electric vehicle industry is followed by new markets and new opportunities for charging piles and charging guns. There are two kinds of charging: DC charging and AC charging. The AC charging gun is a common charging device. The AC charging socket has requirements for flame retardant, weathering and high temperature resistance in the material selection. To this end, we recommend two PET and PA66 materials that meet the above requirements, and teach you what to pay attention to in the two programs.


DC electric vehicle charging pile, commonly known as "fast charging", is a power supply device that is fixedly installed outside the electric vehicle and connected to the AC power grid to provide DC power for the non-vehicle electric vehicle power battery. The input voltage of the DC charging pile adopts three-phase four-wire AC380V±15%, the frequency is 50Hz, and the output is adjustable DC power, which directly charges the power battery of the electric vehicle. Since the DC charging pile is powered by a three-phase four-wire system, it can provide sufficient power, and the output voltage and current adjustment range is large, which can achieve the requirement of fast charging.

AC electric vehicle charging pile, commonly known as "slow charging", is fixedly installed outside the electric vehicle and connected to the AC power grid, and provides an AC power supply device for the electric vehicle vehicle charger (ie, the charger fixedly mounted on the electric vehicle). The AC charging pile only provides power output, and there is no charging function. It is necessary to connect the car charger to charge the electric car. It is equivalent to just playing a role in controlling the power supply.


The charging safety of the charging gun, the plugging and unplugging life of the product, the waterproof rating, the anti-rolling property, the environmental conditions of use, and even the comfort of use are all essential for the use of the charging post. In this era of sustainable development, green travel and green consumption are increasingly recognized by everyone, and the market for rechargeable guns should be broad in the coming years.
