Up to now, new energy electric vehicles have become a trend of contemporary automobile development. Since the advantages of electric vehicles are quite clear, the cost of use is greatly reduced compared to fuel vehicles, and driving on urban roads has the characteristics of quietness and comfort. Electric vehicles have now entered everyone's homes, but car owners will inevitably encounter various problems in daily use, such as: what kind of cable is used to install a 7kw electric vehicle charging pile? So today AG Electrical will show you how to choose a suitable charging cable, hoping it can help you.
For indoor use, use BV wire, 2.5 square meters is enough! It is recommended to use BVV if not poling, which is to add a protection to the copper wire. If 7KW is three-phase, the current is about 14A, and the switch can choose 25A. If it is single-phase, the current is about 35A, and the air switch should be 40A and above.
1. As the energy replenishment device of electric vehicles, electric vehicle charging piles are related to the service life and charging time of electric vehicle battery packs. This is also one of the aspects that consumers are most concerned about before buying an electric car.
2. Achieving fast, efficient, safe and reasonable power supply for power batteries is the basic principle of electric vehicle charger design. In addition, the application of EV car charger adapters and non-EV car charger adapters to various power batteries should be considered.
3. The solution of the charger in the ground charging station. The charger consists of a rectifier that can convert the input AC power into DC power and a power converter that can adjust the DC power of the charger in the ground charging station. The plug is inserted into the matching socket of the electric vehicle, such as the type 2 socket EV, and the DC power is input into the battery to charge it.
