The modular lithium ion power battery comprises a battery box and a supporting plate fixed in the battery box, a bottom opening is formed in the surface of the supporting plate, a variable-pitch adjusting assembly is arranged in the supporting plate and the battery box, a plurality of partition frames are arranged on the variable-pitch adjusting assembly, and a plurality of battery cells are arranged on the partition frames. A module battery body is arranged between the separation frames, and the variable-pitch adjusting assembly comprises two guide rods fixed between the inner walls of the battery box and a screw rod rotationally inserted between the inner walls of the battery box. According to the invention, the variable-pitch adjusting assembly is adopted, except for the rightmost separation frame, the other separation frames can be driven to move, so that the distance between the separation frames is subjected to equal-pitch adjustment, and the module battery body is arranged between the adjacent separati
