What is the lifespan of new energy vehicles?
2 Answers
Similar to fuel-powered vehicles, the lifespan is around 10-15 years, subject to the specific years stipulated by government regulations. Currently, mainstream brands offer a battery warranty of 8 years or 100,000 kilometers. Generally, when the battery reaches the end of its lifespan, it can be replaced. The lifespan of new energy vehicles is no different from that of fuel-powered vehicles. Lifespan of new energy vehicles: In terms of the core components of new energy vehicles, their lifespan depends on the vehicle's battery. New energy vehicles commonly use ternary lithium batteries or lithium iron phosphate batteries. According to the lifespan of ternary lithium batteries, the cycle life is approximately 2,000 cycles. Simply put, a cycle refers to the process from a fully charged state to complete discharge and then back to full charge. Excluding other abnormal conditions, under normal driving habits, taking a 30kWh battery as an example. Battery cycle lifespan: A battery cycle equals the process of consuming 100% of the battery's charge. For example, if the battery is fully charged (100%) on the first day and used until it reaches 0% or is completely depleted, then fully charged again, and on the second day, 100% of the charge is consumed again—this constitutes one battery cycle.
The lifespan of a new energy vehicle depends on how you use and maintain it. The battery is the most crucial component. I've been driving a BYD Blade Battery for six years, and it still gives me over 400 kilometers of range without any issues. Avoid frequently charging to 100% or depleting it completely—keeping it between 20% and 80% is ideal for battery health. Opt for slow charging stations and use fast charging only in emergencies. Most mainstream batteries can endure around 2,000 charge cycles, which is more than enough for a decade or so of regular use. The electric motor is actually more durable than a combustion engine—just remember to change the gearbox oil periodically. Ultimately, the manufacturer's warranty is key; most now offer 8 years or 150,000 kilometers, which is more than sufficient.
