Electric vehicles are also called battery cars, which shows the importance of its key components, and an electric vehicle, there are 2 situations will face the problem of new batteries, the first is the new electric vehicle just bought, the second is the electric vehicle riding for two or three years need to replace the new battery, and the small connoisseur received a question from a netizen: The first charge of the new battery of the electric vehicle to run out of electricity?
As we all know, electric vehicles want batteries to be more durable, its charging specifications play a great role, then, small connoisseurs on the netizens' problems, to introduce some of the content about battery charging, the owner of the car in accordance with the following way to charge, can minimize the non-standard charging caused damage to the battery, but also hope that the owner after seeing, do not charge wrong.
Do the new batteries of electric vehicles have to run out of electricity for the first time?
My answer is "no need", when the mobile phone just came out, it was popular to say that the mobile phone battery was charged for the first time, and it needed to be used up for a long time, which was conducive to the durability of the mobile phone battery, and this practice was because the early mobile phone was equipped with a nickel-cadmium battery, which had a "memory effect", while the electric vehicle battery was a lead-acid battery or a lithium battery, which did not have a "memory effect".
And the new battery of the electric vehicle is charged for the first time, it should not be used up and then charged, the correct is that the new battery should be filled and reused, this is mainly because whether it is a new electric vehicle or a new battery, it is difficult to do it at the factory, there will be inventory time, and the manufacturer will not fill the battery when it leaves the factory, therefore, as the owner of the car in the use of the new battery, to fill the battery and then continue to use, otherwise it is easy to use the battery for the first time to "undervoltage", which will cause irreversible damage to the battery. Affects the battery's range.
In addition to the first charge, the new battery wants to be more durable, it should start from the daily standard charging, the following small connoisseurs to inventory the 3 methods in the charging process, are relatively standardized and correct, hope to help the owners.
When is it more appropriate to charge? Remember 3 charging methods
1. The first year of charging of the battery needs to strictly comply with the charging recommended time of the manual
The capacity of the new battery will be 100%, this time charging, it is necessary to charge according to the charging time of the instructions, such as the charging time mentioned in the instructions for 6 hours, then, the charging time should not be lower than this time, of course, do not be too long, it is best not to exceed the length of the instructions for 1 hour.
The purpose of this is to charge the battery capacity to 100%, because the current electric vehicle charger, are three-stage, many car owners will mistakenly think that the charger becomes a green light is full, directly unplug the charger, and this battery capacity is not necessarily fully charged, so for the sake of insurance, the owner should do enough charging time, so as to avoid the charger is still in the "float charge" stage, unplug the charger, causing damage to the battery.
2. The battery is "deep discharge" at least once every 2 months, and then charged
When the battery is charged daily, it should be kept at about 30% of the power should be charged, such a charging method will be conducive to the prolongation of the life of the battery, however, experienced teachers will suggest that the battery in every 2 months, at least once to carry out a "deep discharge", the so-called "deep discharge" refers to the number of electric vehicles in the dashboard, has been basically 0 electricity state.
Speaking of this, there are always car owners who will question, is such a power loss not very harmful to the battery? In fact, when the power of the dashboard is 0 electricity state, the battery is not a serious "power loss", all batteries have undervoltage protection, there will be a certain residual electricity, as the bottom line of battery discharge, and the benefit of such "deep discharge" is to make the positive plate porous structure in the battery α lead oxide into β lead oxide, and the charge capacity of β lead oxide is higher than that of α lead oxide, which will increase the capacity of the battery.
However, it is worth noting that such an appropriate "deep discharge" is good for the battery, but frequent "deep discharge" will lead to easy softening of the positive plate, and even lead to the shedding of the active substance, affecting the life of the battery.
3, battery charging summer and winter duration should be distinguished
The ambient temperature for battery charging is still a relatively large impact, in general, when the temperature is relatively high, the active substance in the battery is more active, the charging efficiency is relatively high, and when the temperature is relatively low, there will be active substance inactive, electrolyte cooling, resulting in a relatively low charging efficiency.
Due to the existence of such characteristics of the battery, in the summer and winter charging time can not be completely consistent, in the summer temperature is higher, most of the battery charging time is controlled at 6 to 8 hours, and if the temperature is low in winter, most of the battery charging time can be controlled at 8 to 10 hours, so that the battery can be filled more full, but try not to exceed 12 hours.
The summary of the small connoisseur: the battery of the electric vehicle is a relatively "delicate" part, it can be used for 1 year or 3 years, largely depends on the owner's maintenance of it, the above charging suggestions, including: the new battery should be fully charged for the first time and then used, the battery in the first year charging time is not lower than the instructions recommended time, the battery needs the appropriate "deep discharge", the battery charging time is slightly shorter in summer, slightly longer in winter, these are charging methods that are conducive to extending the life of the battery, hoping to help everyone.
You also know which battery charging maintenance methods, or want to know what aspects of the knowledge, but also welcome everyone to comment together to communicate, pay attention to electric vehicle experts, every day to share electric vehicle related information and views.
