Li Auto (NASDAQ: LI) has launched its in-house developed electric powertrain technology system named Lianshan, covering batteries, electric drive units and charging network.
The company pledged two lifetime guarantees — against battery self-ignition and against fire after collisions — as it seeks to ease consumer safety concerns while expanding the use of its in-house batteries.
The Chinese automaker announced the system at its Power Day electric technology event on Tuesday. It said the Lianshan battery, Lianshan electric drive and charging network are all developed in-house, and that it will take care of "everything about electricity."
Under the Lianshan battery guarantee program, if a vehicle self-ignites due to quality problems with the original battery and meets scrapping criteria, Li Auto will compensate the owner with a new vehicle of the same configuration.
If a battery catches fire following a collision or chassis scraping and the vehicle is scrapped, the company will cover the gap between the vehicle damage insurance coverage amount and the actual insurance payout. The program is subject to eligibility conditions.
The launch comes as Li Auto accelerates the switch of its models' batteries from CATL (HKEX: 3750) to in-house developed batteries, which are produced by a 50-50 joint venture it established with Sunwoda (SZSE: 300207) in 2025.
79% stake after the deal closes, becoming its second-largest shareholder.
