What is the national standard warranty period for electric vehicles?

[DiMelanie]

The national standard warranty for electric vehicles requires new energy vehicle manufacturers to provide quality guarantees for energy storage devices such as power batteries, drive motors, and motor controllers to consumers. Passenger vehicle manufacturers should offer a warranty period of no less than 8 years or 120,000 kilometers (whichever comes first). According to the current warranty service standards announced by various automakers for vehicles and batteries, most power batteries come with a 5-year or 100,000-kilometer warranty. Extending battery life primarily depends on charging methods. New energy vehicle batteries commonly use ternary lithium batteries, which have the advantages of high energy capacity and low pollution. The normal lifespan of a qualified ternary lithium battery is 8 years, with a driving range of 150,000 to 200,000 kilometers. Maintaining a steady speed while driving is crucial, as aggressive driving can cause damage to the battery. Additionally, it is essential to develop the habit of charging the electric vehicle frequently. Prolonged battery depletion can significantly reduce its lifespan, so regular charging is key.
