Whether it is on the avenue or the small road, as long as it is not a highway, viaduct, these roads that do not allow electric vehicles to travel, we can see the figure of electric vehicles, as an electric vehicle with light and affordable characteristics, it is now a means of transportation that many families have, then, this also means that many people will have such a "task" every day, that is, to charge electric vehicles.
But when charging, often encounter poor battery life in winter, summer batteries will bulge, do not know, these are largely because of the charging is not standardized to cause "damage" to the battery, then, when charging, what charging methods will hurt the battery, how to charge more correctly, small connoisseurs will come to target electric vehicles "daily charge" and "use up charge", which hurt the battery? How to charge properly? For a detailed introduction.
Irregular electric vehicle charging will hurt the battery
Many car owners think that the battery of the electric vehicle is damaged because of the riding process, just like the car, "violent" driving will hurt the engine and other parts, but according to the experience of the maintenance master, most of the electric vehicles are "not bad, but charged", therefore, irregular charging is the biggest "culprit" that hurts the battery.
This is mainly related to the structure and working principle of the battery, the structure of the battery is mainly electrolyte, positive and negative plates, separators, and the working principle is mainly through the active substances of the positive and negative plates, to continuously store electricity, the input electrical energy into chemical energy that can be saved to store, and in such work, whether it is electrolyte, positive and negative lead plates, are very easy to injure the object.
The electrolyte will be evaporated due to high temperature, and the active substance of the positive and negative lead plates will be charged irregularly, so that the active substance will fall off, and even the battery will crystallize and vulcanize, affecting the capacity of the battery, so that the battery storage capacity is weakened, and the electric vehicle is not far away.
What is the impact of charging electric vehicles every day?
So, the charging of non-standard electric vehicles will hurt the battery, and electric vehicles are charged every day, is it standardized? The answer is that there is definitely an impact, and it will affect the life and endurance of the battery.
Because no matter what type of battery, there will be a design of the number of charge and discharge, to lead-acid batteries as an example, its number of charges is only about 350 times, some poor quality batteries, even this number of times can not reach, small connoisseurs have also seen only 180 times of lead-acid batteries, such batteries, if charged every day, then, 350 times of charge and discharge, only enough for 1 year, and 180 times of only enough for half a year, then, the battery is durable.
Therefore, from the perspective of extending life, small connoisseurs are not recommended to charge electric vehicles every day, of course, there are also owners who say that if they do not charge, they are worried about the next day's insufficient power consumption of the car, for this helpless situation must be charged, I can also understand, which is why I recommend that all car owners, when choosing electric vehicles, to ensure that its endurance can be maintained for 3 to 4 days, if you use a car for 10 kilometers per day, choose 20AH batteries, you can 50 kilometers, if you use a car for 20 kilometers per day, Choose a 32AH battery and have a range of 100 kilometers, so that the battery life will not be affected by frequent charging.
Electric vehicles are charged when they are used up, and do they hurt the battery? Which will hurt the battery more
In addition to "daily charging", there are also some car owners who have the habit of "recharging when they are finished", so will such charging habits hurt the battery? My answer "will hurt".
If the electric vehicle battery, completely used up and then charged, it will lead to the battery "loss of power", do not underestimate the damage caused by the loss of power, frequent power loss, will make the positive and negative plates in the battery cause irreversible damage, premature crystallization, vulcanization and other aging phenomena, battery life will also be greatly reduced, use soon.
So, if you want to compare the two, "use up and recharge" or better than "daily charging", after all, the damage caused by power loss is slow, accelerated aging also has a certain time, the normal life of the battery is 3 years, accelerated aging can also be used for about 2 years, and in order to use enough power in the driving distance, the owner can not do the state of power loss every day.
How to charge the electric car correctly will not hurt the battery
The damage to the battery of the electric vehicle basically comes from 2 problems, the first is the evaporation of the electrolyte caused by high temperature, which causes the bulge, shortening the life, and the second is because of the damage of the active substance and the lead plate, resulting in crystallization, vulcanization and other aging problems, then, correct charging, it is necessary to avoid the possibility of causing these 2 kinds of damage.
Several charging methods to avoid battery crystallization and vulcanization
1, do not use fast charging, especially the fast charging station on the street, the input of large current will impact the lead plate, resulting in battery crystallization and aging;
2, the battery should not be used at a loss of electricity, it is recommended that every time the electric vehicle is used, the residual power is about 25% to replenish the power, and the timely replenishment of the power can reduce the formation of active substances and lead plates;
3, in the case of sufficient power, do not charge, many car owners, the battery is obviously still fifty percent, sixty, and even more power, to charge the electric vehicle, which will cause a backlog voltage, so that the battery crystallization;
4, the temperature is too low to charge, when the temperature is lower than 0 ° C, lithium batteries will produce "lithium dendrites", resulting in a reduction in battery capacity.
Several charging methods to avoid high temperatures in the battery
1, avoid charging all night, the general electric vehicle charging time is about 6 hours, the battery capacity is slightly larger, but also in about 8 hours, rarely the battery design charging more than 10 hours, because, the longer the time, the battery continues to be in a high temperature state, will damage the battery;
2, after the end of the ride immediately charged, after the end of the electric vehicle riding, the battery is a discharge working state, the temperature is higher, should be cooled for 15 minutes, and then charged;
3, after charging immediately riding, the battery in the charging state is also in a state of high heat, this time also needs to be cooled and then ridden, especially in the case of higher outdoor temperature;
4, the use of small current charger charging, to the electric vehicle charger must be matched, too small charger will reduce the charging efficiency, it is easy to let the battery in the charging process overheating.
Small connoisseur summary: the battery of electric vehicles is relatively easy to damage the parts, which is also the weakness of the current battery, and when charging electric vehicles, "daily charging" and "use up recharging" these 2 are more extreme, is to try to avoid, the car owner to develop a more standardized charging method, so that it can more effectively extend the battery life, so that the battery will not be used for 1 year on the battery life is greatly discounted.
