How Long is the Lifespan of New Energy Vehicle Motors?

[VonDaniel]

New energy vehicle motors have a lifespan of 2-8 years, for the following reasons: Charging reasons: It is necessary to charge the battery promptly when it is about to run out of power. Generally, when the fuel gauge light comes on in a conventional car, there are still about 10L of fuel left in the tank, allowing for an immediate refill at a gas station. However, if a new energy vehicle battery is not charged in time when it is depleted, the sulfuric acid will oxidize, leading to insufficient charging. Over time, this will also reduce the battery's lifespan. Battery type reasons: Main types include ternary lithium batteries, lithium iron phosphate batteries, lithium manganese oxide batteries, and lithium titanate batteries. The latter two currently occupy a very small market share, so we will focus on ternary lithium and lithium iron phosphate batteries. According to national regulations, when an electric vehicle's power battery capacity degrades to below 80% of its new state, it can be considered the end of the power battery's service life.
