With the popularity of electric vehicles, EV charging guns have become an essential tool for car owners. Among them, portable charging guns are more popular. A portable charging gun is an easy-to-carry and use tool that can charge an electric vehicle anywhere a power source is available.
The portable charging EV car consists of a charging head and a charging cable. The charging head can be easily plugged into the charging port of an electric vehicle and provides the required current and voltage while charging. The charging cable is connected between the charging head and the power supply to transfer power to the electric vehicle battery. They can be charged anywhere an outlet is installed, such as at home, an office, or a shop.
The function of the portable charging gun is to provide a convenient way to charge electric vehicles. The charging gun can help electric vehicle owners charge more easily, thus expanding the range of electric vehicle travel. Portable charging guns can also provide owners with emergency charging services. If the electric car loses power during the journey, the owner can use a portable charging gun to charge the electric car in order to safely reach the destination.
In addition, the portable car EV charger has a variety of functions. It can carry out fast charging, improve charging efficiency, and save costs and time. It can also monitor charging current and voltage to ensure the safety and effectiveness of charging. If anything goes wrong, it automatically stops charging, thus protecting the charger and the electric car.
Housing materials for portable charging guns
The development of new energy vehicles, naturally, and new energy vehicles supporting charging piles and charging guns. As an electric vehicle 
charging connector, the charging gun is a "bridge" between charging facilities such as charging piles and electric vehicles, and at the same time, it is also tied to the safety of users when charging. In the process of designing the charging gun, the material has strict requirements, and the stability and safety of its design need to be attached great importance.
Portable EV chargers are usually made of a variety of materials, including copper, plastic and high-strength steel. Copper is typically used to make electrode heads, which have excellent conductivity, and the larger the contact surface between the negative electrode and the battery, the higher the charging speed and efficiency. At the same time, the thermal conductivity of the copper material is also very exceptional, which can quickly dissipate heat and avoid overheating damage to the equipment. The plastic material is mostly used for the shell of the charging gun, which has the characteristics of lightweight, fireproof, moisture-proof, etc., which can effectively protect the equipment from the external environment. In addition, high-strength steel is used in the internal structure of the charging gun, which can improve the strength, wear resistance and durability of the charging gun.
The material advantage of portable charging guns lies not only in their physical properties, but also in their convenience for automotive use. The portable charging gun has the characteristics of compact and light, easy to carry and store, and is convenient to charge at any time. At the same time, its safety and stability have also been fully guaranteed, which can effectively prevent the occurrence of unexpected safety problems such as overload. And the scalability and compatibility are also very good, which is suitable for almost all types of new energy vehicles.
In general, its material needs to have the following characteristics.
1. Charging gun shell material not only requires good insulation performance, but also high CTI, high searing wire, flame retardant, especially fast charging pile, high voltage current has higher performance requirements for materials.
2. Excellent weather resistance, anti-oxidation and anti-UV. Since the charging pile is in the open space, and even the sun and rain, the charging gun should have exceptional weather resistance to ensure safety in long-term use.
3. Super low temperature resistance toughness, -40℃ can maintain good impact performance.
4. High flow, splendid processing performance.
5. Can meet the needs of various colours, designers need to choose the right material according to their own design needs.
Commonly used charging gun materials are PC, PC/ABS or PC/PBT. Although PC has high impact toughness and good weather resistance, its material fluidity is poor, and it is easy to produce stress residual during processing. PC/ABS material has good fluidity and high CTI, but its weather resistance is poor, and heat resistance is low. PC/PBT material has good fluidity, high hot wire temperature, exceptional solvent resistance, but its leakage resistance constant index (CTI) is low, and the shrinkage rate of the material is large.

Q: How to extend the life of EV charging gun?
A: (1) Unplug the charging gun in time after use;
(2) Avoid pulling and bending the charging gun during use;
(3) Clean the electrodes and connecting ends of the charging gun every once in a while.
Q: Can portable charging guns be used in all new energy vehicles?
A: Generally speaking, portable charging guns can be applied to all new energy vehicles. However, different car brands and models require different charging power, so you need to choose a charging gun suitable for your model when buying a charging gun.
Q: There are many kinds of charging gun interfaces, how to distinguish them?
A: At present, electric vehicle charging standards are divided into CHAdeMO, CCS, GB/T three, and different models need different interfaces. Therefore, when purchasing a vehicle and choosing a charging pile, it is necessary to choose carefully to avoid interface incompatibility.
