Selecting Electronic Components: How to Enhance Connection Stability in 7KW AC Charging Piles?

The rise of new energy vehicles has boosted demand for home charging piles. Among them, 7KW AC chargers are now the most popular. They have a good power level and are easy to install. But, the charging pile’s internal wiring affects its performance and safety. In particular, the design of the wiring from the air switch to the control board at the AC input end is critical. It determines the charging pile’s stability. This article examines the wiring selection strategy for a crucial connection.

About electrical performance and safety.

Electrical performance and safety considerations are the core elements in the selection. The 7KW AC charging pile works at 220V. It’s a typical low-voltage, civilian application. To ensure safety and handle voltage fluctuations, use a cable rated for at least 300V. This provides a safety margin. Also, the greatest input current may reach 32A. So, the air switch is usually rated at 40A for extra protection. The connecting cable’s current capacity must match or exceed it. Thus, we recommend 10AWG cable. It can carry enough current. It also maintains a stable current while charging. This ensures the charging pile’s safety.

About material selection and environmental adaptability

One cannot ignore the aspects of material selection and environmental adaptability. The internal connecting wire needs low wear, tear, and corrosion resistance. In the charging pile’s actual use, it may face outdoor or semi-outdoor conditions. Even indoors, it may face dust and humidity. Standard PVC insulated cables can work at -30°C to 60°C for charging piles. For more reliable applications, consider using high-temp PVC or XLPVC (cross-linked polyethylene) insulation. These materials can endure extreme temperature changes. They also have better chemical stability and strength. This improves the durability and stability of charging piles.
