The practicality and convenience of electric vehicles have been deeply liked by the people, with the advantage of being more convenient than cars, a family with one or two electric vehicles, can solve the problem for family travel, and is cheaper, follow-up costs less, which is why more people like it. The two most commonly used charging methods for car owners are charging and recharging every day, which method will damage the battery more largely, which method will be more correct? Today, Duo Bin will explain to you at one time in response to these 2 problems.
The importance of batteries to electric vehicles, if you want to be durable, maintenance
Battery as one of the most core components of electric vehicles, the smooth travel of electric vehicles mainly depends on the use of the battery, to determine whether a good electric vehicle runs far, less problems, many people in the battery selection and charging are very concerned. As the most expensive part of the electric vehicle, the battery is used for a long time and the endurance is near and far, so it is necessary to pay attention to the method of battery use and maintenance.
In addition to the natural aging and decline of the battery, the two biggest injury points are the correctness of charging and using methods, and the normal maintenance of the battery must be done, so that your electric vehicle battery can be used longer and run farther.
Will the battery of the electric vehicle be damaged every day? Does it have an impact on battery life?
Choosing electric vehicles as a travel tool, charging is an inevitable job of every car owner, many people have been used to charging, and do not know whether this charging method will damage the battery? Daily charging is the simplest method that many car owners often use, in order to make the electric car fully charged every day, afraid of going to the halfway out of power, has been using this method.
This charging method is relatively large damage to the battery, according to industry standards, lead-acid batteries cycle charge and discharge times in 300 to 400 times. Not to charge once to calculate, but to superimpose to calculate, charging frequency is too much, the number of folding times will be more, the number of times the battery recycling will drop quickly.
Another point of lead-acid battery inside the acid as a lead plate protective liquid, there is a certain dose, if the number of charging too much, too diligent, the battery is easy to heat, this distilled water evaporation is relatively fast, the protective effect of the lead plate will be reduced, the power storage will be reduced, the endurance will be less and less, the battery will also decline in advance.
Which injury is smaller when it is used up? How to charge properly
Riding electric vehicles pay more attention to battery use and maintenance of car owners, battery use in what state to charge very carefully, in the riding will often observe how much the amount of battery to reach, master when the electric vehicle should be charged. Some car owners who do not pay much attention to observation are charging the car by feeling, generally there will be a basic use of electricity, the car is not going to be charged, but also use the way of charging every day, the battery damage is very large.
Electric vehicles are used up and recharged, the controller has a minimum voltage protection function, such as 48V20Ah electric vehicles, the controller minimum voltage protection is 42V, when the battery's power is used below 42V, the electric vehicle basically does not go, this control protection for the battery is certainly good, do not let the battery power is too short, the impact on the damage to the battery is small, this situation the owner will use the use of the recharge method more.
Most car owners use observation when riding the fuel gauge to drop to 20 to 30% to charge, after using up the recharge is smaller than the daily charging damage, it will be better, using this method, the correctness is higher.
If you want the battery to be more durable and have a longer battery life, there are 3 key points that need to be paid attention to by car owners:
The first: avoid the battery "overheating" standard to make the battery decay too fast
Lead-acid battery heat is afraid of low temperature, when the weather is cold, whether it is a new battery or an old battery, due to weather problems, the battery life will be reduced by about 30%, the hot temperature will rise on the same day, the battery storage will return to the best state, and the battery will play the best role in the temperature of 20 ~ 25 ° C.
Under normal circumstances, the battery should not be hot when running and charging, due to long-term use or charging in the high temperature state, the longer the time the higher the temperature, the temperature of the battery reaches more than 30 degrees, the battery begins to bulge outward, the lead plate will crystallize and oxidize, the acid that protects the lead plate will evaporate quickly, the double loss of the battery will decline early, the endurance will decline, the life will be shortened, and the normal can be used for two years, in this case, more than a year is broken.
Duo Bin suggested: electric vehicles in the hot period of long-term riding will generate heat, just stop do not rush to charge, rest for an hour or so to charge as well, charging time should not be too long, in the charger to become a green light floating charge for about an hour or so disconnected is best.
Second: insist that the battery is not "overcharged" requirements
Usually in the maintenance, some owners reflect that the electric vehicle can not run on the road, can not be charged, after inspection there will be a filling drum, and even the phenomenon of spitting acid, this situation is caused by overcharging.
What kind of charging tried overcharge? Refers to the battery normal charge is 8 hours fully charged, the charger becomes a green light. Some car owners use the method, a charge is a night, or even plug in the charger on the matter, more than a few hours, this is overcharging.
Some of the chargers used are ordinary without power failure protection, but the charger is full after changing the lights, and there is a power in- and continuously open. After professional testing, there is still about 0.3 volts of current entering, and even the charger that automatically loses power has a current of 0.08 to 0:1 volts.
When charging for a long time, the power supply is either battery filling drum, or the acid evaporation is completed, and the battery storage capacity is reduced, which is to make the battery decline early, and guide the importance of letting go of the power supply in time
Duo Bin suggests: the charger should be replaced with a good quality of automatic power off for several years, correctly use the charging method and master the charging time, prevent the overcharge of the power supply from being disconnected in time, so that the operation battery can be used for more than one year.
The third: avoid street fast charging and high-power fast charging
Now some electric vehicles support fast charging, that is, there are dedicated batteries and chargers, support fast charging design function, most lead-acid batteries do not support fast charging, like some emergency fast charging machines on the street, can only be used as a time for the car to ride to the halfway no power emergency use, can not be used frequently, the current pay more than double the charger, charging time is too long, too frequent will make the battery charge drum, charged bad.
Another point some families have several electric vehicles, the battery is installed with 48V20Ah, 60V2 or 60V32Ah, the battery model and the charger is matched, if you do not pay attention to the high-power charger to charge the small ampere number of batteries, the time is too long, the over-frequency battery will be charged or damaged.
Duo Bin's suggestion: the charger is broken, match the same model in time, do not take a high-power charger to charge the battery of the small ampere, if you use it can be used as an emergency for 1 to 2 hours, and then even if you match the same type of charger.
In short, every day charging and use up recharging, the latter way will be correct, want the battery more durable, long battery, use the correct way, I have instructions later, you can make a reference. Electric vehicles in use often have owners will overheat, overcharge, fast charging and other incorrect operating methods, the final result of the operation is battery charge or early recession, are not advisable, the correct method is also shared with everyone, can refer to.
