How Many Kilometers Can a New Energy Vehicle Travel?
1 Answers
New energy vehicles can travel up to 400 kilometers on a single charge. There are three main types of batteries commonly used in electric vehicles on the market: lead-acid batteries, nickel-metal hydride batteries, and lithium manganese oxide batteries. The core technologies of electric vehicles include the battery, motor, electronic control system, as well as traditional automotive technologies such as chassis systems. Below is an introduction to the types of batteries used in new energy electric vehicles: 1. Lead-acid batteries: Lead-acid batteries are low-cost, perform well in low temperatures, and offer high cost-effectiveness; however, they have low energy density, short lifespan, large size, and poor safety. Due to their low energy density and short lifespan, electric vehicles powered by lead-acid batteries cannot achieve high speeds or long driving ranges, and are generally used in low-speed vehicles. 2. Nickel-metal hydride batteries: Nickel-metal hydride batteries are low-cost, mature in technology, long-lasting, and durable; however, they have low energy density, large size, low voltage, and suffer from memory effect. Although their performance is better than lead-acid batteries, they contain heavy metals, which can cause environmental pollution if discarded improperly. 3. Lithium manganese oxide batteries: Lithium manganese oxide batteries are low-cost and feature cathode materials with good safety and low-temperature performance; however, the material itself is not very stable and tends to decompose, producing gas. Therefore, they are often mixed with other materials to reduce battery cell costs. However, their cycle life deteriorates quickly, they are prone to swelling, have poor high-temperature performance, and relatively short lifespans, making them mainly suitable for medium and large-sized battery cells.
