Electrical and Mechanical Properties

• Electrical Properties: It shall have good electrical conductivity and low contact impedance to reduce heat generation and energy loss. For example, according to national standards, the maximum contact impedance of the charging gun pin is specified as 0.5mΩ.

• Mechanical Properties: It shall possess high mechanical strength and durability, and be able to withstand frequent plugging and unplugging operations. Generally, the number of no-load plugging and unplugging cycles is required to be more than 10,000.
