BEIJING (Reuters) – CATL, China’s leading manufacturer of electric vehicle (EV) batteries, said on Wednesday it had sued small rival China Lithium Battery Technology Co (CALB) for alleged intellectual property violations.
CATL, which supplies Tesla Inc and Volkswagen AG, said in a statement the lawsuit related to batteries made by CALB using its new technologies which have been installed in tens of thousands of vehicles.
CATL filed a complaint in the southeastern city of Fuzhou, near its headquarters in Ningde.
CALB, which provides GAC, said in a statement on its Wechat account that it focuses on independent research and technological advancement.
The batteries it supplies to customers have passed assessments to make sure they don’t violate the intellectual property rights of others, he added.
Batteries are essential components of electric vehicles, and Chinese companies are expanding their production globally.
According to the China Automotive Battery Innovation Alliance sales ranking, CATL was China’s top manufacturer of electric vehicle batteries in the first half of this year, followed by BYD and LG Energy Solution. CALB was # 4, with a much lower market share than CATL.
