There are four charging connection modes for electric vehicle charging cable:
Charging mode 1: single head charging gun + Cable + ordinary CEE plug connected to single-phase mains power
Charging mode 2: single head charging gun + Cable + control box + plug connected to single-phase mains power
Charging mode 3: single head charging gun + Cable + control box + plug connected to single-phase mains power
Charging mode 4: it is a combination of charging gun + Cable + charging pile connected to DC
The difference is: the difference between charging mode 2 and charging mode 1 is to increase the controller. Compared with charging mode 1, charging mode 2 has complete protection measures, including overvoltage, undervoltage, overcurrent, overtemperature and leakage power-off protection, while charging mode 1 has no protection measures. Three phase charging mode for the first two modes, mode 3 increases the charging current, thus increasing the charging speed, and the demand for charging safety will be higher. Charging mode 4 is DC charging gun.
Of course, there are three connection modes. The charging cable is connected with the electric vehicle end and pluggable with the power grid end; The charging cable is connected with the power grid connection end and can be unplugged with the electric vehicle end; The charging cable can be plugged in and out with the electric vehicle end and the power grid connection end.

As a bridge connecting the pile and the vehicle, the charging cable briefly introduces the characteristics and differences between TPU and TPE.
The English name of TPU is the abbreviation of thermoplastic polyurethane. The main characteristics of TPU are: a wide range of hardness, and with the increase of hardness, its products still maintain good elasticity and wear resistance, high mechanical strength, outstanding cold resistance, good processing performance, oil, water and mold resistance, and good recovery and utilization. Under the condition of high hardness, the elastic loss of TPE is greater than that of TPU.
TPE English name is the abbreviation of thermoplastic elastomer, which means thermoplastic elastomer. It has the characteristics of environmental protection, non toxicity, safety, wide hardness range, good coloring, soft feel, weather resistance, fatigue resistance, high temperature resistance and so on. It can be recycled and reduce costs.
At present, the insulation and protection materials of automobile harness with temperature grade of 105 and below are mostly PVC materials. PVC materials for domestic automobile harness often have some disadvantages, such as rough extrusion surface and poor low-temperature performance. In view of this, combined with the special environment of automobile harness (such as narrow space, poor heat dissipation, frequent mutual friction, etc.), special requirements (thin wall, high-speed extrusion, etc.) and cost control requirements, it is necessary to study the PVC material for automobile harness to further improve its performance.
Nowadays, electric vehicles are very common in society. Especially in recent years, new energy electric vehicles have made a breakthrough in sales and even have the opportunity to surpass traditional fuel vehicles. Compared with fuel vehicles, electric vehicles are special, with the characteristics of high voltage and high current. They are usually equipped with power supply systems with more than 300V and current of more than 200A. This is completely different from the traditional car only equipped with 12 / 24V power supply system. The safety measures of high-voltage distribution box, high-voltage line and connector of electric vehicle have become the safety aspects that need to be paid attention to.
High voltage line of electric vehicle refers to the component of connecting circuit formed by punching copper contact terminal (so-called connector) and wire (cable) after crimping, wrapped with plastic compression insulator or external metal shell, etc. In terms of function, there are two kinds of power lines carrying the power of driving actuator (actuator) and signal lines transmitting sensor input commands. Power lines are divided into low-voltage harness and high-voltage harness.
The traditional connector equipment has been difficult to meet the requirements of high current and high voltage. The connector of electric vehicle must be a high-power connection product. If it does not meet the requirements, the electric vehicle fire accident is inevitable. Electric vehicle connectors must be automotive grade products, and industrial grade products do not meet the requirements. The main indicators include IP grade, insulation grade, low resistance, error proofing and locking function.
So, is electric vehicles safe? Analysis on safety technology and measures of high voltage devices is electric vehicle safe or not? Analysis of safety technology and measures for high voltage devices: high voltage harness is the cable between the connectors in the electric vehicle and is a very key connector to support the safe operation of the whole vehicle. First, it is required to be shielded, have IP grade, prevent overheating or combustion. The vehicle is used in a harsh environment. If it does not meet the requirements, it is the most prone to spontaneous combustion. Therefore, electric vehicle high-voltage line plays an important role, and the quality of electric vehicle high-voltage line is very important. #omgevcable
