Electric vehicles in the countryside basically every household has, in the city there are also many families in use, the reason for its popularity is mainly cheap and convenient to use, therefore, it can quickly seize the transportation market, today, once the mainstream of bicycles, motorcycles, has been occupied by electric vehicles into a niche model, it has become the biggest "winner" in two-wheeled transportation.
Of course, electric vehicles are not without shortcomings, compared with bicycles, motorcycles, electric vehicles are too dependent on a certain part of the model, and this part is a very high cost of the battery, and the battery in addition to expensive, there is a feature, that is, its durability is relatively poor, slightly irregular use, will make him "very hurt."
Therefore, electric vehicles want to be more durable, strengthen the maintenance of the battery is essential, and battery maintenance is necessary to start from every detail, such as electric vehicles are not full to unplug the charger, which is what many car owners will encounter, in an emergency need to go out, choose a large capacity battery, need to charge 10 hours to full, but only 8 hours of charging time per day, will lead to unplugging the charger in advance, then, what impact will this behavior have on the battery? The little connoisseur explains it clearly at once.
Electric vehicle batteries have no memory effect and will not directly cause capacity reduction
Not full on the unplug the charger, many people have believed in a saying, that is, the battery is a "memory effect", this time is charged to 90% of the capacity, unplug the charger, the next time in the charging, the battery can only be fully charged to 90% of the capacity, directly caused by the capacity reduction, and this statement, in fact, is wrong.
At present, widely used batteries, in fact, do not have a "memory effect", the real existence of "memory effect" of the battery is mainly nickel-cadmium batteries, nickel-metal hydride batteries, of which nickel-cadmium batteries are the first generation of mobile phone batteries, therefore, when buying mobile phones before, will be told by the merchants, the first few times charging must be full, which also leaves many people such a misunderstanding, batteries have "memory effect", but in fact, these batteries have long been eliminated from the mainstream battery market, the current application of lead-acid batteries and lithium batteries, are not" Memory Effect".
What are the real effects of unplugging the charger when the electric car is not full?
But although the electric vehicle is not full and unplugged, it will not directly lead to the reduction of capacity, but such a way is still not worth advocating, it will still cause "damage" to the battery, including damage to the calendar life of the battery and the number of cycles of charge and discharge, which will bring the impact, mainly the following;
Injury 1: Waste of charge and discharge times, the number of charge and discharge is to determine the battery life, performance of the indicator, the number of battery charge and discharge is only about 300 times, can not say that it is particularly small, but if the owner of the car to charge every day, it is indeed not much, but if each time is spent a number of charges, but not full, this is a waste.
Injury 2: Leading to overheating of the battery, many car owners can not wait to fully unplug, are because of the rush to use the car, such a situation, will lead to the battery in the charging time of the heat has not yet dropped, immediately cycling and because of the battery discharge heat, resulting in battery overheating, and the battery overheating brings is water loss, bulging, active substance softening and falling off, endurance decline, battery life shortening and other issues. The small connoisseur especially reminds that no matter how urgent it is, it is necessary to give the battery a 10-minute cooling time, so as to avoid overheating the battery.
Injury 3: Increases the risk of using fast charging, if the battery is not fully unplugged, if the battery capacity is large enough, the battery is far enough, it will not have an impact, but many electric vehicles, the endurance is only 30, 40 kilometers, and only half of the riding, will lead to the risk of electric vehicles in the middle of the road no electricity, this time, the owner can only use the fast charging station on the street, but this device, in fact, has a great harm to the battery, its voltage is too high, will impact the battery, let the active substance fall off, Frequent use will make the battery unable to charge and the capacity will be reduced, which is also a potential risk.
What is the situation is full, many car owners do not judge accurately
Whether it is potential or will be directly caused, electric vehicles are fully charged, there must be some impact, as the owner, want the battery to be more durable, it is necessary to avoid, and the source of avoidance, it is necessary to judge what situation is full, what situation is not full.
Speaking of this, some car owners will refute, this is not simple, the charger "red light for charging, green light for full", this is common sense, but in fact, this is a misunderstanding, our mainstream electric vehicle chargers, are "three-stage", that is, including: constant voltage, constant current, trickle, these 3 stages of charging, only these 3 stages are all completed, the capacity of the battery will reach 100%.
Among them, trickle charging refers to the charging stage after the charger turns to a green light, therefore, to think that the charger becomes a green light means full, such a judgment method is inaccurate, then, how to accurately judge, the small connoisseur has 2 suggestions;
Suggestion 1: directly through the dashboard to view, this is the simplest way, most of the current electric vehicles are used according to the battery residual voltage conversion percentage, so that the amount of power can be seen at a glance, when the electric vehicle becomes a green light, open the dashboard to see if the power is 100%, after reaching full power, unplug the charger.
Recommendation 2: Choose the smart switch charger, if you feel that the initiative to view the amount of power, a little troublesome, now the charger has a lot of smart switch charger, it can intelligently monitor the battery power to reach how much, when the power reaches 100%, the charger will automatically power off the shutdown, which will be more worry-free, but also because to avoid excessive floating caused by battery loss, or a more recommended way.
Small connoisseur summary: In summary, the electric car is not full to unplug the charger, will certainly have an impact on the electric vehicle, of course, if there is really an emergency, this rare case as long as the battery cooling time is given, occasionally will not cause too much damage to the battery, as a car owner, should avoid is "frequent" not full on the unplugged charger, and this "frequent" is often unconscious, do not know that the electric car is not actually full, therefore, through the dashboard to view the power or choose the smart switch charger, It is a good way for you to correctly judge whether it is full, and to do this, you can try to avoid battery damage and make the battery more durable.
