Stung by the broader market weakness and deterioration in sentiment toward Chinese stocks, the EV sector closed the week ending Dec. 17 mostly in the red. Tesla, Inc. (TSLA) came under selling pressure amid further stock sales by CEO Elon Musk. Meanwhile, Rivian Automotive, Inc. (RIVN), which is touted to be a Tesla challenger, had a forgettable week.

Here are the key events that happened in the EV space during the week.

In other noteworthy Tesla news, Musk announced on Twitter that Tesla will try out Dogecoin (DOGE-X) payments for some merchandise. He also released another video tour of Tesla's Giga Shanghai.
