What kind of battery is used in electric vehicles on the market, whether it is two-wheeled, three-wheeled or sedan?
Low-end electric vehicles or electric bicycles generally use lead-acid batteries, that is, two-wheeled, three-wheeled or old-man music
Pure electric vehicles and some hybrid vehicles use lithium iron phosphate batteries. Mid-to-high-end electric vehicles generally use ternary lithium batteries
Regardless of the type of battery, their lifespan is mainly determined by the number of cycles the battery has, not the number of charges!
The first thing to understand is that the number of cycles does not equal the number of charges. The number of cycles refers to the process of the battery completing a full flush and full discharge, that is, the battery with 100% power is used to 0% and then charged to 100%, which is called a cycle.
For example, the battery was 100% on the first day, and I used up 30% when I went to the market and charged it to 100% when I got home in the evening. The next day, I went to a friend's house and used 70% of it, and at night I charged it to 100%, a total of two charges in the past two days, but this can only be regarded as one cycle.
No matter how many times we charge it, it is only once when the battery completes a complete 100% charging and discharging process. The number of cycles can affect the service life of the battery, regardless of the number of charges.
Do different types of batteries have the same number of cycles?
Different types of batteries have different cycles, that is, different lifespans.
Lead-acid battery: The number of cycles is about 500 times.
The number of cycles of ternary lithium battery is about 1000 times.
The number of cycles of lithium iron phosphate batteries is about 2000 times.
Today's new energy vehicles can run 500,000 kilometers based on 1,000 cycles and a full battery life of 500 kilometers. Therefore, when buying a new energy vehicle, you don't have to worry about battery life, just drive it with confidence.
