The advent of electric vehicles has made people abandon the once well-known 28 bicycle, and now many families will have an electric car to facilitate travel, but with the increasing number of electric vehicles, its charging methods have also become diverse.
The charging method of electric vehicles has also become arbitrary, such as the common now, full of unplugged, or dissatisfied with the unplugged, etc., but these methods really do not damage the life of the battery?
The charging is not right, and the battery is scrapped
The electric vehicle maintenance industry has always had an unchanging truth, as long as the battery has a problem, most of them are caused by inattention to charging, and this is also a common thing to do in daily life, and it is also one of the most direct ways to cause damage to the battery.
First of all, for the situation of full charge but not pulling, it will directly affect the life and use of the electric vehicle battery, many chargers will have indicators, the indicators are generally red and green to remind whether the electric vehicle is fully charged, but few people will pay attention to the indicators.
The second is that the charger of the electric vehicle does not mean that it can be plugged in to be charged, and it is also necessary to pay attention to the current of the electric vehicle battery, and for long-term non-unplugging of the charger, it will cause damage to the battery and reduce the battery life, and at this time, if the charger is not unplugged, there will still be a weak current.
Although nothing will happen in a short period of time, but for a long time, this floating charge will form an overcharge state, which will accelerate the loss of water from the battery and cause excessive decomposition of lead sulfate.
The excessive decomposition of lead sulfate will cause sulfation, which will make many lead plate batteries vulcanized, which will directly damage the service life and endurance of the battery, which is why many electric vehicles now need to be charged frequently and have a short battery life, and even some electric vehicles will cause spontaneous combustion when the temperature rises during the charging process.
We will encounter many unexpected things in our lives, and at this time, our electric car may still be charging and not full, in this case, we will choose to ride the electric car immediately, but this method of pulling out the charger without being full will also lead to battery damage.
The second is that the way of charging electric vehicles is actually a fixed cycle, if according to the normal and correct use method, the battery life is generally about three years, and the life of the lithium battery is about five years, but it is also many incorrect ways of use that cause the battery to often appear two years or even a year to change.
The situation of unplugging without full charge will increase the circulating discharge of the battery, and the life of the battery will be directly shortened, although it will not cause direct damage to the battery, but it will cause the battery usage to become shorter, and the battery will often be replaced.
The right way to charge
The power of the electric car can generally be charged at about 20 percent, and don't be in a hurry to pull out the charger after the electric vehicle is fully charged, it is generally best to wait for about ten minutes, but not many people care about the charging of electric vehicles, so the charger has also been improved in this case.
Now many chargers will automatically stop charging after being full, but the price of this charger will be more expensive than the price of the general charger, the emergence of this smart electric vehicle charger is to increase the service life of the electric vehicle battery, and the smart charger will be powered off by itself after being fully charged.
In addition to smart chargers, there are also some technological products, such as timer plugs, which are actually very common nowadays, such as those used for some convenient fast charging on the street.
The second is that many communities are now popular with this charging method, but there will also be that kind of paid timing charging, the charging pile of the community will be charged within the time of payment after paying the fee, and the second is the mixed use of chargers, for example, the voltage and charging output of different brands of chargers are not the same.
In particular, the use of cross-brand chargers will directly cause damage to the battery, because the output and acceptance of the current is likely to be substandard or cannot be charged because of the small current, or the battery is overheated during the charging process, so the original charging equipment is selected as much as possible for charging.
These are places that we will not pay attention to in our daily life, but it is precisely these situations that will not be noticed that cause many things to be caused by battery cars, especially the spontaneous combustion of electric vehicles, many battery cars are very easy to spontaneously combust in summer, which is also because of the electric vehicle battery.
Spontaneously combusting electric vehicles
The harm caused by the spontaneous combustion of electric vehicles will be publicized every year, but there will still be spontaneous combustion of electric vehicles every year, and the spontaneous combustion of electric vehicles is also because of the battery.
The second is that the lithium battery will cause a short circuit in the positive and negative electrodes after being damaged, causing the battery heat to rise out of control and cause spontaneous combustion.
For example, the battery car in the corridor spontaneously combusts, the temperature of the corridor is too high in summer, and in order to facilitate charging, the electric car is selected to push the electric vehicle into the corridor on their own floor for charging, and the battery car will also cause battery heating during the charging process, and the temperature is too high in summer, resulting in the problem of spontaneous combustion caused by the electric vehicle, and some are the hidden dangers of the battery itself but are not found.
Electric vehicle battery overcharge, overdischarge, short circuit, high temperature and battery line aging will cause spontaneous combustion of electric vehicles, so in daily life, you also need to pay attention to whether there are hidden dangers in the electric vehicles you ride every day to and from work, and regularly check the battery and electric vehicle lines This is also an essential process.
