What type of battery is used in new energy vehicles?
2 Answers
New energy vehicles use the following battery types: 1. Cobalt oxide 18650 battery: Representative models: Tesla MODEL S. This type of battery has mature production technology and high specific energy, approximately twice that of lithium iron phosphate batteries. However, its stability at high temperatures is slightly inferior compared to nickel-cobalt-manganese (NCM) and lithium iron phosphate batteries. 2. Nickel-metal hydride battery: Representative models include Toyota Prius, Ford Escape, Chevrolet Malibu, and Honda Civic Hybrid. The greatest advantage of this battery type is its excellent safety performance, but compared to lithium batteries, it has lower specific capacity and larger volume.
I've recently researched quite a few new energy vehicles, and they mostly use lithium batteries as the core power source. The most common are lithium-ion batteries, which are divided into two major categories: lithium iron phosphate and ternary lithium. The former offers high safety and low cost, like BYD's Blade Battery which is widely adopted, with strong temperature adaptability but slightly lower energy density. The latter, such as Tesla's battery packs, has high energy density and long range but is more prone to issues under high temperatures. Lithium batteries store and discharge electricity through ion movement, supporting fast-charging technology, allowing a charge of just half an hour to cover hundreds of kilometers. However, battery lifespan is also affected by charging habits; frequent deep discharges can shorten it. Future optimization directions include improving charging efficiency and cycle times, making daily driving more worry-free and reliable.
