As a "electricity" as the power of transportation, charging is an indispensable step in the process of using the car, although, at present, only a few brands, including Yadi, Wuling have launched a "power exchange" electric vehicle, can not be charged, can only "change the power", but such a model, has not been widely recognized, after all, "power exchange" compared to charging, will be more troublesome, the cost will be higher.
Although charging yourself is very convenient, the cost will be cheaper, but the process of charging, but it is easy to hurt the battery, why the same battery, some owners can only use 2 years, some owners can use 3, 4 years, a big reason is that charging is not standardized, an irregular charging method, because of persistent use, will make the battery life decay.
Almost every owner has to charge an electric car, so have you ever considered whether it is better to "charge every day" or "recharge when you run out"? These 2 common charging habits, what kind of differences will there be, what are their drawbacks, small connoisseurs share the answer for you below, so that you can figure it out at once.
The drawbacks of "charging every day"
For the battery capacity of electric vehicles is relatively small, "charging every day" is the norm, of course, this situation, no matter how big the "drawbacks" are, or should be charged to charge, after all, although the battery damage is serious, but if there is no power in the middle of the road, it will be more serious, but for some battery capacity is relatively large, "charging every day" is not a good choice, let's analyze the drawbacks of this charging method.
Disadvantage one: waste, if it is not necessary to charge the case of charging, it will cause 2 aspects of waste, the first is definitely a waste of time, electric vehicle charging has been relatively frequent, compared to other means of transport, belongs to the "charging" troublesome model, in the case of unnecessary, "daily charging" is actually very unnecessary.
The second is definitely the waste of cycle charge and discharge times, which is an important indicator of the length of battery life, but also the core selling point of the battery, ordinary lead-acid batteries, generally only 250 times to 350 times of cycle charging times, the number of charge and discharge times, the battery will fail, for the number of lead-acid batteries that are not much, waste once, is to shorten its service life.
Disadvantage two: accelerate the aging of the battery, the battery in each charging process, the need for lead plate active substances to react, the input current into "chemical energy" storage, and after the conversion work, will form a certain vulcanization, that is, the embodiment of crystallization, this is the symptoms of battery aging, frequent charging, will make vulcanization serious, which means that the battery aging accelerates.
Small connoisseur reminder: Therefore, in the case of non-essential, it is not recommended that electric vehicles "charge every day", this way is only harmful and no benefits, however, now more and more lithium battery electric vehicles, due to the internal materials of lithium batteries, different processes, plus its number of charge and discharge is very high, can reach 1000 times to 2000 times, in general, lithium battery electric vehicles do not need to worry about "daily charging", it can be charged with use.
"Use up and recharge" drawbacks
Although the electric vehicle power "runs out and recharges", although it can play a role in not causing waste and avoiding battery aging caused by charging, if the power is completely used up and charged, it is actually very harmful to the battery.
The battery has 3 major fears, 1 fear of overcharge, 2 fear of overheating, 3 fear of overdischarge, and if the electric vehicle is "used up and recharged", it belongs to the battery overdischarge, and over-discharge means that the battery has overdraft, that is, the actual working voltage of the battery is lower than the discharge termination voltage for a long time, and frequent overdraft of the battery will lead to irreversible damage inside the battery, seriously hurting the battery, causing performance, life, and endurance to decline.
Small connoisseur reminder: Of course, the overdischarge is based on the actual working voltage for a long time below the discharge termination voltage, but in fact, the battery will have a self-protection voltage setting, in general, the voltage displayed by the instrument, will not reach such a situation, only after listening to the ACS function or through the controller conversion voltage, there will be a low working voltage, resulting in battery overdischarge.
Comprehensive "daily charging" and "use up recharging" of the drawbacks of the comparison, small connoisseurs can conclude that in the case of normal use of electric vehicles, the habit of "running out of recharging" will be better, in general, as long as it is not a long-term low power drive, the damage caused to the battery is limited, if it is a lithium battery electric vehicle, in these 2 options, it can be more arbitrary charging, will not cause battery damage.
Finally, small connoisseurs should remind a little, no matter which charging method, whether it is lead-acid batteries or lithium batteries, we must avoid mixing chargers, using fast charging stations, these 2 charging methods will have more serious damage to the battery, and for lithium batteries, do not charge in the environment below 0 ° C, otherwise it will aggravate the formation of "lithium dendrites" and harm the battery.
So, which one do you usually choose, "recharge every day" or "recharge when you run out"? Do you feel any differentiation? Welcome to comment and exchange, pay attention to electric vehicle experts, and share electric vehicle related information and views every day.
