Today, with the increasingly serious environmental pollution and national policies, hybrid and pure electric vehicles are increasingly recognized by consumers and have entered consumers' homes. Compared with fuel vehicles, although hybrid electric vehicles and pure electric vehicles have been recognized by consumers, consumers are also more and more concerned about the batteries of hybrid electric vehicles and pure electric vehicles. There will be other problems, which have become a major factor that plagues consumers. Then, let's talk about the battery issues of hybrid electric vehicles and pure electric vehicles, and see how long it takes to replace them.
First of all, let's start with hybrid vehicles. The batteries of hybrid vehicles can basically be divided into ternary lithium batteries, lithium iron phosphate batteries, and nickel-metal hydride batteries. Among them, the first two kinds of ternary lithium batteries, lithium iron phosphate batteries belong to lithium batteries, and the cycle life of ternary lithium batteries is within 1000 times, while that of lithium iron phosphate is about 2000 times. It is used in hybrid electric vehicles for 10 years and 200,000 kilometers. Not much pressure. The Ni-MH battery has a service life of about 500 cycles. In addition, as far as hybrid car batteries are concerned, you can buy them with confidence without worrying about battery life.Also read:how to charge lithium ion battery without charger
Next, let’s look at the battery life of pure electric vehicles. If a long-life lead-acid battery is used, the life of the battery generally needs to be replaced in 1.5-2 years, but if it is a lithium iron phosphate power lithium battery, the theoretical life is 7-8. year. Of course, for pure electric vehicles, the service life of the battery does not have a fixed time and number of years, it mainly depends on the user's car environment and the driver's situation. Generally speaking, as far as hybrid and pure electric vehicles are concerned, battery technology has also been greatly improved. If consumers want to buy them, they are worth buying.
Car batteries, the manufacturer's warranty policy is generally 10 years. But in fact, except for Toyota's hybrid Ni-MH batteries, many lithium batteries can't last that long.
Compared with nickel-metal hydride batteries, lithium batteries have many advantages, such as high energy density and faster charging and discharging. They are indeed very suitable for new energy vehicles, especially pure electric vehicles. However, the biggest problem with lithium batteries is that the battery decays too quickly.Also read:Lithium ion Battery Pack Manufacturer
Ni-MH batteries have slow battery degradation, but low energy density, so they are not suitable for pure electric vehicles.
What will accelerate the battery decline? It is overcharge and overdischarge!
If you often fully charge the battery, or often recharge the battery after running out of power, or often charge it with a DC charging pile, the battery must decay quickly. Basically, the battery will begin to decay after charging 500 times.
