4.1 Sign color and format

4.1.1 General requirements

4.1.1.1 The color and format of the signs for electric-vehicles' charging/battery-swapping facilities shall be in accordance with the color and size of the facilities, and environmental characteristics of the site.

4.1.1.2 The format of the sign shall be selected from Figure 1 ~ 6. The color shall be those from Figure 1 ~6. Among which the color code for blue shall be CMYK. C100 M52 Y0 K0, PANTONE. 2935PC; and that for black shall be C0 M0 Y0 K100, PANTONE. Pro.BlackPC. The color of the graphic symbols and text shall be in enough contrast with the background color of base-material. The base-material's background color of the sign shall not be the safety color - red or yellow as specified in GB/T 2893.1.

Note1. The CMYK color mode is a printing mode. The four letters refer to Cyan, Magenta, Yellow, Black, representing four colors of printing ink.

4.2 Size of Sign

4.2.1 General requirements

4.2.1.1 The minimum size of the electric-vehicle's Charging/Battery-swapping

Infrastructure sign shall be determined according to the observation distance (D) of the sign.

4.2.1.2 After the observation distance is determined, the corresponding size of sign (h, w) shall be selected from Table 2.

4.2.1.3 In application, signs in Figure 1 ~ 6 shall be amplified in proportion.
