Functional and Safety Requirements for Electric Vehicle Charging Cables

Functional and Safety Requirements for Electric Vehicle Charging Cables

Electric vehicle charging is like people's three meals a day, providing energy to the body and maintaining normal life activities. How to charge electric vehicles intelligently and quickly is the top priority of research and development by many automakers. For electric vehicles, the charging device must meet the requirements of safety, convenience, economic cost, efficiency, etc. Currently, common charging methods on the market include conventional charging methods such as charging pile charging stations, battery replacement, and wireless charging. Way. So how much do you know about electric vehicle charging cables?

1. Functional requirements of electric vehicle charging cables

The electric vehicle charging cable is the carrier connecting the electric vehicle and the charging pile, and its basic function is to transmit electric energy. However, with the development of charging technology, in order to better complete the charging process, there needs to be communication between electric vehicles and charging piles, and automatic control when necessary. Therefore, the charging process puts forward higher requirements for the charging cable. The charging cable not only needs to have the function of power transmission, but also needs to transmit the status and information of the vehicle and power battery to the charging pile for real-time interaction. The action is controlled in order to complete the charging process safely and reliably.

2. Safety requirements for electric vehicle charging cables

At present, the safety of electric vehicles has become the focus of the industry. The charging and discharging process of electric vehicles, due to the long time, high current intensity, and high frequency of use of charging cables, its safety should be highly valued. On the basis of ensuring good insulation performance, electric vehicle charging cables should have high heat resistance and aging resistance. At the same time, they should have good low-smoke and flame-retardant properties when burning to ensure that losses and injuries are minimized.

3. Can the electric car charger extension cable be fully charged?

It depends on which end you use the electric car charger extension cord to extend. If you extend the 220V end, there will be no problem within 100 meters. If it is an electric vehicle charger extension cable that extends the end connected to the battery, it is very particular. This needs to be calculated according to the wire section, charging current and wire length to obtain an accurate number. And usually how to maintain electric vehicles, increase his life? The first is charging. The charging of general models is determined by how long the car has been driving. We must ensure that it is fully charged, instead of keeping the car in a charging state all the time. Charging for a long time will cause problems such as battery overheating. Those with charging protection function also need to pay attention to this. Secondly, use a professional electric vehicle charger, keep a dry and ventilated place in a cool place, avoid exposure to sunlight and humid environments, and avoid water ingress into the charger.
