With the continuous improvement of people's awareness of environmental protection, new energy vehicles have become the mainstream of future travel, and the charging of electric vehicles has also become the focus of attention for car owners. Electric charging cable types have become a popular charging solution.
A portable charging cable is a kind of charging device that can be carried around, which is convenient and fast. Compared with traditional charging piles, portable charging cables do not require fixed installation and wiring and can easily charge electric vehicles in any place, making charging easier and more convenient.
The new energy portable charging gun uses DC fast charging technology, which has the characteristics of fast charging speed and high charging efficiency. With the increasing popularity of the electric vehicle industry, portable charging cables have also become an important way to cope with the demand for urban charging. For example, when the battery of an electric vehicle is low, it can be charged at an outlet at home or at a nearby charging station through a portable charging cable to meet the needs of daily travel.
There are numerous brands and models on the market for electric charging cable types, and the quality and performance of the products vary widely. When purchasing, you need to pay attention to the brand, specifications, scope of use, charging speed, safety, and other aspects of the product, and choose formal channels to purchase to ensure the quality and after-sales service of the product.
The emergence of portable charging guns provides a more convenient way to charge electric vehicles, making new energy travel more practical and convenient. It is believed that, under the impact of continuous technological updates and innovations, portable charging guns will become more and more popular and become the mainstream way of charging electric vehicles.
Analysis of common problems of slow charging of new energy vehicles
1. It cannot be charged when using a portable charging cable.
(1) The socket has no ground wire, the charging system enters leakage protection mode, and K1 and K2 are disconnected, resulting in the inability to charge. Judgment method: one is to judge by the flashing mode of the alarm light of the control box on the cable (see the car manual for details); the other is to insert the three-phase plug into the 220V socket and use a multimeter to measure whether the CP end of the charging gun head and the PE end have a voltage of about 12V (AC and DC), if there is a ground wire in the socket, and vice versa.
(2) The S3 switch is damaged and cannot be closed. Detection point 3 always detects the RC+R4 resistance value and always judges that the charging gun is not plugged in properly (half-contact state) and cannot send a charging-ready signal. Judgment method: In the power-off state, use a multimeter to detect the resistance of the CC end and the PE end of the charging gun. The resistance value before and after pressing the mechanical lock button is different; otherwise, the S3 switch is damaged.
2. Is the charging speed the same for charging the same vehicle with different charging cables?
The answer is likely to be different.
The key to determining the charging speed of the charging gun is the RC resistance, which determines how much charging current the charging gun can output to the vehicle. The output current rating is the same, but the RC resistance (CC and PE resistance when the mechanical locking button is not pressed) will be different depending on the brand/type of charging cable. If you use different charging cables to charge the same vehicle, whether the charging speed is the same depends on whether the RC resistance value is the same.
3. Is the charging speed the same for different models with the same charging cable?
Again, the answer is probably different. Because the output rated current of the charging gun is not equal to the actual maximum charging current, the actual maximum charging current is also related to the power of the on-board charger, the condition of the power battery, and other factors. For example, if the slow charging pile in Table 2 is used to charge the vehicle, although the output rated current of the slow charging pile is 32A, if the power of the vehicle's on-board charger is not large enough to withstand such a large charging current, the actual maximum charging current will be less than 32A.
