Follow the knowledge of the big university: the big university has a trick to extend the battery life
Cleaner and more environmentally friendly electric vehicles will become the future pillar of the automotive industry. This consensus has been deeply rooted in people's minds. As ICers at the forefront of technology, they must be drooling over a good electric car! But when it comes to buying a car, everyone has the same love-hate relationship with electric cars as you do!
The highlight of electric vehicles is that they are electric, but the pain point is also electric -
the batteries are expensive and not durable
. The high cost of batteries is the main source of profit for electric vehicle manufacturers. In some models, the cost of batteries even reaches half of the price of the whole vehicle, which is also the main reason why electric vehicles have not been popularized so far.
Not only are they expensive, but their service life is also not good. According to the general warranty policy in the industry, under normal use, the battery life of electric vehicles is eight years or 160,000 kilometers. This number itself has no advantage over fuel vehicles. In addition,
in reality, not everyone knows how to maintain the battery
, so this life is greatly reduced.
Life lies in maintenance. Today, I will be your teacher and introduce you to a few tips to make your battery stronger and stronger! Friends, please take out your pen and paper and write down carefully:
1
Don’t overcharge
I believe this is already a consensus. The principle is simply that the life of the battery is calculated according to the number of cycles of "full charge - full discharge". Devices such as laptops and mobile phones that are often fully charged and then used up are very prone to battery loss. The battery basically needs to be replaced after three or four years. Everyone should have a deep understanding of this.
The same is true for electric cars, so when charging your car, you might as well leave some space, which can reduce the number of charging cycles. Electric cars can charge themselves when braking or going downhill, so leaving some space is just right for use.
The Japanese are very considerate in their service. A Japanese electric car company has developed a power limit function, setting the full charge threshold at 80%. This ensures that there will be enough power while taking into account the space mentioned above. But we might as well pay attention to this.

Avoid deep discharge
After talking about charging, the corresponding point is that you should not use too much electricity. Lithium batteries do not have a memory effect, so deep discharge has no meaning for lithium batteries, but will damage the battery life. For pure electric vehicles, partial discharge is the best way to use electricity. Repeated charging and use of electricity in the appropriate power range is the best choice.
There are also special tips for plug-in hybrid vehicles: hybrid vehicle batteries will lose more power because hybrid vehicles generally switch to gasoline power mode automatically when the battery is exhausted. Deep discharge is difficult to avoid. At this time, you should be good at using the battery management system and
manually switch to engine mode before the battery is exhausted
. Sometimes, if you need to travel long distances and other high-power driving, it is best to switch to mountain mode to avoid sudden excessive power consumption.

The charging process also has its own requirements
Charging time also affects battery life. If the battery is almost empty, slow charging for 8-10 hours is fine, but if the battery still has some power, it is best
to control the charging time to less than 8 hours
. After charging, turn off the power in time, otherwise there will be a risk of overheating.
Many car owners are like you, they like to go to sleep while charging, and the battery will be fully charged when they wake up the next day. Although it saves time, it will damage the battery. So everyone should just watch the charging carefully.

Physical care of the battery
Just as people need maintenance, so do car batteries! First of all,
avoid exposing your car to the sun
. An environment with excessively high temperatures will increase the internal pressure of the battery and cause the battery to lose water, resulting in a decrease in battery activity and accelerated aging of the plates.
Then
Avoid sudden acceleration
. If an electric car accelerates suddenly, it will form a large current discharge, produce lead sulfate crystals, and thus damage the physical properties of the battery plate. Therefore, when starting, going uphill or changing lanes, try not to accelerate suddenly.
Also, do not leave the battery in a low-power state when it is not used. If the battery is stored in a low-power state, sulfate crystals will adhere to the plates, blocking the ion channels and reducing the battery capacity. The longer the battery is idle in a low-power state, the more the battery capacity will decrease. Therefore, if the electric car or
battery is not used, it is best to charge it once a month
to keep the battery healthy.
I have shared all my knowledge with you this time. Have you ICers learned anything? If you have learned something, please put it into practice and take good care of the battery. If you have not learned anything, please turn to the top and read it again carefully.
The great teacher will teach you until you learn it. If you don’t understand, you can learn again for free.
(Note: The information comes from the Internet)
There are prizes for expressing your feelings. ICers are welcome to express their feelings to you!
If you love someone, just say it out loud! You confess your love and I give you a gift
