Battery is one of the most important components of electric vehicles, and the current electric vehicle equipped with batteries, mainly divided into lead-acid batteries and lithium batteries these 2, because, lead-acid batteries market share is relatively high, and the life is relatively short, very much need to maintain the battery, before the small connoisseurs most of the dry goods knowledge shared, are for lead-acid batteries.
But with the electric vehicle lithium battery application is also more and more, many owners of electric vehicles are also using lithium batteries, often there are car owners on the inquiry, there is no lithium battery related knowledge sharing, small connoisseurs will write a special article about the maintenance of lithium batteries, hoping to give lithium batteries to electric vehicle owners, help.
Is it useful to learn how to maintain lithium batteries?
From an objective point of view, understanding the maintenance of lithium batteries is far less meaningful than lead-acid batteries, after all, compared to lead-acid batteries only 1 to 3 years of life, the difference between maintenance and non-maintenance is very large, eliminating the trouble of frequent replacement of batteries, and the life of lithium batteries is generally about 5 to 10 years, even if it is not deliberately maintained, as long as there is no special non-standard, the habit of hurting the battery, with about 5 years is not a problem.
However, if the lithium battery wants to be used for 10 years or more, maintenance is essential, coupled with the emergence of spontaneous combustion problems in lithium batteries now, maintaining the battery can not only increase durability, but also improve safety, from this level, small connoisseurs or recommend electric vehicles equipped with lithium batteries, learn to maintain methods, the following to share a few methods.
5 methods of maintenance of lithium batteries
1. Control the charging time to avoid overcharging
Lithium batteries and lead-acid batteries are different, it has the conditions of fast charging, therefore, matching different current chargers, charging time differences are also a lot, to 48V20AH batteries as an example, if equipped with 5A charger, then, its charging time generally does not exceed 5 hours, it can be fully charged, if equipped with 10AH charger, generally about 2 hours, can be full, therefore, lithium batteries do not charge is a whole night, long charging.
Maintenance tips: And many car owners can not actually do timed to unplug the power supply, this time you can choose some switch sockets with timing, according to the size of the battery capacity to set the charging time, to avoid overcharging damage to lithium batteries.
2. Avoid charging in a high temperature, closed environment
Lithium batteries are not so safe, especially ternary lithium batteries, there will be a risk of spontaneous combustion, which is what many car owners understand, and spontaneous combustion and high temperature have a certain relationship, therefore, when charging lithium battery electric vehicles, remember not to charge in a high temperature environment, or closed space will form a high temperature environment, otherwise it will not only hurt the battery, but also have safety risks.
Maintenance small suggestions: in the summer high temperature weather, try to choose the night charging, this time the temperature is relatively low, can reach the lithium battery charging the best 25 ° C or so, and, try to avoid fully enclosed space charging.
3. Avoid charging in an environment where the temperature is lower than 0 °C
Although the lithium battery is discharged, its low temperature resistance is better, but when it is charged, the damage of the low temperature to the battery is actually greater, because once the temperature is lower than 0 ° C, the lithium battery will precipitate "lithium dendrites", its appearance not only affects the battery life, once too much, it may also puncture the separator in the lithium battery, resulting in the emergence of spontaneous combustion risk.
Maintenance tips: And high temperature weather charging choice at night, in the winter such a low temperature environment charging, try to choose daytime charging, in most places on the mainland, even if the winter daytime temperature is generally not lower than 0 ° C, so that charging reduces the damage to lithium batteries.
4. Do not charge immediately after riding
Through the above several methods, it can be seen that lithium batteries are actually the same as lead-acid batteries, with both cold and heat properties, and lithium batteries in the process of charging and discharging, will release heat, in order to avoid excessive heat, when charging, to avoid just riding the electric vehicle, immediately charged.
Maintenance tips: After the lithium battery has just been discharged, the battery heat will not disappear quickly, so it is necessary to cool down for at least half an hour or so, and then charge, which can reduce the superposition of charging heat and discharge heat at this time, causing damage to lithium batteries.
5, long placement time, do not fully charge placed
Electric vehicles will inevitably encounter a period of time not to use, compared to the lead-acid battery recommended after the full charge, placed, and lithium battery practices are not the same, once the battery is fully placed, will cause the voltage instability of lithium batteries, there will be safety factors, which the owner needs to pay attention to.
Maintenance small suggestion: When the lithium battery electric vehicle needs to be placed for a long time, when the battery is charged, it can be charged to about 80% and unplugged, so that the placement for three months will not have too much damage to the lithium battery, of course, if the placement time is too long, it is still necessary to recharge the battery in the middle.
Summary: The above is the lithium battery of the electric vehicle, in the process of charging need to pay attention to the 5 maintenance methods, relatively speaking, are relatively simple, but more harmful to the battery, and this is also a lot of car owners often have non-standard charging habits, if the owner can do "charging time has a degree, not charging in a high temperature, low temperature environment, riding the car immediately charged, idle is not full", then, your electric vehicle lithium battery will be used longer than when not maintained, basically use lithium battery design 10 years of life is not a problem.
