The CATL Tectrans Bus Edition is being put to use in 80 models, the battery maker said.

CATL is the world's largest power battery maker, with a 37.6 percent global share in January-July, according to South Korean market researcher SNE Research.

In China, CATL's share was 46.2 percent in January-August, according to China Automotive Battery Innovation Alliance (CABIA).
