Method of establishing visual images of models of battery status

A method of establishing visual images of models of battery status, the method comprising:

• collecting a plurality of data values of at least one characteristic parameter of one of a plurality of battery modules in one of a plurality of time periods;
• a control unit forming at least one first characteristic image and a second characteristic image according to the plurality of data values;
• the control unit forming one of a plurality of variant images by superimposing the at least one first characteristic image and the second characteristic image, wherein each of the plurality of variant images comprises at least one variant area;
• and
• the control unit forming at least one moving variant area by superimposing the plurality of variant images corresponding to the plurality of time periods, wherein the at least one moving variant area is formed by a time variation of a combination of the at least one variant area of each of the plurality of variant images;
• wherein the at least one first characteristic image, the second characteristic image and the plurality of variant images are images with a plurality of pixels, and the pixels of the at least one first characteristic image and the second characteristic image are normalized pixels converted from the plurality of data values.
