Changan New Energy E-PRO, Chery Tiggo e, Weltmeister EX6, BYD Tang EV, and NIO ES6 manufacturers promise lifetime warranty for these 5 models. Changan New Energy E-PRO, warranty policy: Lifetime warranty on power battery cells with no restriction on the first owner (non-commercial vehicles or annual mileage not exceeding 30,000 km). Chery Tiggo e, warranty policy: First owner gets lifetime warranty on the three-electric system (non-commercial vehicles). Weltmeister EX6, warranty policy: (Non-commercial vehicles) The vehicle warranty period is 4 years or 120,000 km, with a lifetime free warranty policy for the power battery. BYD Tang EV, warranty policy: (Non-commercial vehicles) The vehicle warranty period is 6 years or 150,000 km, with core components like the three-electric system covered for 8 years or 150,000 km, and lifetime warranty on power battery cells. NIO ES6, warranty policy: First owners (non-commercial vehicles) automatically enjoy three lifetime free benefits: lifetime free warranty on the vehicle and the three-electric system, lifetime free roadside assistance, and lifetime free vehicle internet services. Additionally, NIO currently offers free battery swap services for first owners. Both commercial and non-commercial vehicles are types of motor vehicles allowed on Chinese roads, but they differ in aspects like operational nature: Different nature: Commercial vehicles have "commercial" indicated in the usage section of the vehicle registration certificate; non-commercial vehicles have "non-commercial" indicated. Required documents differ: Commercial vehicles need a road transport permit from the transport management department; non-commercial vehicles do not require this permit. Driver requirements differ: Drivers of commercial vehicles need both a driving license for the vehicle type and a professional qualification certificate; non-commercial vehicle drivers only need a driving license. Fees differ: Commercial vehicles must pay regular transport management fees to the transport management department; non-commercial vehicles do not incur any transport management fees. Legality of operation differs: Commercial vehicles can engage in profit-driven road transport activities; non-commercial vehicles cannot engage in profit-driven road transport activities.

I remember there are quite a few new energy vehicle brands in the market currently offering lifetime battery warranty services. For example, BYD has this policy on many of its main models, which remains valid as long as the owner regularly maintains the vehicle at authorized 4S shops. Some early Tesla models also had similar coverage, though there might be conditional restrictions or purchase plan requirements now. NIO, through its BaaS (Battery as a Service) leasing program, effectively covers lifetime battery warranty. Additionally, XPeng and Li Auto have also included this service in certain promotions or specified models. I think choosing such vehicles is particularly cost-effective because the battery is one of the most expensive components, and long-term warranty coverage can save a lot on repair costs while also improving the vehicle's resale value. Consumers should carefully read the contract details before purchasing, paying attention to mileage limits or whether original manufacturer maintenance is required. As competition intensifies, more brands may follow this trend in the future to attract more buyers to switch to new energy vehicles.
