How to charge the battery of new energy vehicles? It's not as simple as you think
Recently, I heard that my neighbor's newly bought electric car had a problem, saying that the battery was not working, and it was useless after less than two years of driving. This made me think about it, how should we charge it normally? Is it better to be full or not to be full? There's a doorway here!
The "little secret" in the battery, you may not know
When it comes to electric car batteries, it's a baby bump. There are two main types of batteries on the market: lithium iron phosphate batteries and ternary lithium batteries. These two batteries are like two brothers with very different personalities, each with its own characteristics.
Lithium iron phosphate battery, it is like a hard-working old scalper, with a long lifespan and can be used for 3000 to 5000 cycles. As for the ternary lithium battery, like a squeamish little princess, the life span is slightly shorter, about 1000 to 2000 cycles. However, although this little princess is squeamish, she has high energy density and strong battery life, so she is also very popular.
I've heard that some veteran drivers recommend keeping the battery between 20% and 80% charged, saying that it will make the battery live longer. That sounds reasonable, but what should be done?
Is it really good to be fully charged? Don't "break up" the battery
Speaking of which, I really thought that the fuller the battery, the better. Who knows, this charging is still exquisite!
Regularly filling the battery is like feeding yourself every day, how can you stand it in the long run? The internal pressure inside the battery will increase, the chemical reaction will be more active, and it will also be prone to heat up. Just as people are prone to sleepiness when they eat too much, they can become "lazy" if the battery is too full.
One study says that if the battery is charged to 100% frequently, the battery life may be shortened by 20 to 40 percent. In this way, the battery that could have been used for 5 years may not work for 3 years. That's a big loss!
But then again, you can't keep the battery in a state of "starvation" all the time. Keeping the battery low for a long time is also not good for the battery. Just as a person will be weak when he is hungry for a long time, the battery will also be "weak".
Give the battery a "bath" to make it last longer
Speaking of which, I am reminded of a piece of news I saw the other day. It is said that some electric car owners find that the remaining mileage displayed by the car is not the same as the actual situation, and sometimes it is quite different.
It turns out that this has something to do with our "bathing" of the battery. Especially for lithium iron phosphate batteries, it has to be given a "whole body health care" every 2 to 4 weeks, that is, fully charged. Doing so will help the battery recalibrate and make the charge level more accurate.
Think about it, too, it's like we all have to take a hot shower once in a while to relax. The same goes for the battery, once in a while to let it "stretch and stretch", it is also good for its health.
Charging is knowledgeable, don't "waste" the battery
At the end of the day, charging a battery really depends on "electricity". Different types of batteries have different charging strategies.
Take lithium iron phosphate batteries, for example, which are durable, but they also need to be calibrated regularly. As for ternary lithium batteries, you have to be more careful and try to avoid frequent deep charging and discharging.
Also, we have to formulate a charging strategy according to our own car habits. For example, if you drive to and from work every day and it's not a long distance, you don't have to fill it every day. It's good to stay between 50% and 80%. But if you're on a long business trip, there's nothing wrong with a full charge before you go.
In short, when it comes to charging, you have to pay attention to a "degree". Neither can be too "picky", always do not feed the battery; You can't be too "generous", always hold the battery. We need to find a balance so that the battery can meet our car needs and live longer.
Will the batteries of the future be "smarter"?
Speaking of which, the current electric vehicle battery is much stronger than before. However, there are still quite a few people who are worried about the battery life.
It is said that some new technologies are being developed, and the batteries of the future may be "smarter". For example, some people are working on self-healing battery materials, and others are exploring how to improve the energy density of batteries. If these technologies can be successful, then we will be more worry-free to charge in the future.
I heard that a foreign battery company claims that the new battery they have developed can support more than 10,000 charge and discharge cycles. If it's true, that's awesome! However, this technology is still some way from being applied on a large scale.
Having said that, although technology is advancing, we users also have to learn to use it correctly. It's like some people buy a good mobile phone, but because of improper use, it breaks down within two years. The same goes for electric vehicle batteries, which must be cherished.
A few heartfelt words for new energy vehicle owners
Having said so much, I actually want to tell you: we have to treat the battery of electric vehicles like our own body, and we can neither treat it badly nor get used to it too much.
Charge normally, try to keep it between 20% and 80%. Occasionally come to a deep charge and discharge to give the battery a "bath". Before going out, fill it when you should be full, and don't block yourself.
In the end, I think it's a wise move to choose a new energy vehicle. Although there are still such and such small problems, with the advancement of technology, I believe that it will get better and better in the future. We must not only be enthusiastic about new technologies, but also learn to use them scientifically. In this way, we can truly enjoy the convenience and fun brought by new energy vehicles.
