Electric vehicles are vehicles that rely on electric drive, so electric vehicles need to be charged frequently, so as to ensure the normal driving of electric vehicles, when charging electric vehicles, different people have different charging methods, recently someone asked in the background, electric vehicles "charge every day" hurt the battery?
The benefits of "charging every day" for electric vehicles
Electric car charging every day means that the electric car must be charged every day, will this harm the battery? What are the benefits? There are two main benefits.
1. Avoid running out of power in the middle of the electric car
When using an electric vehicle, you should charge the electric vehicle every day after use, so that you can avoid the situation that there is no power on the second day when riding the electric vehicle, and it will not affect the normal use of the electric vehicle on the second day.
Some people may say that their electric car by the ACS charging function, when the battery is out of power, press the charging switch can also be riding a few kilometers, in fact, this function is to reduce the protection voltage of the battery, if used often, it may cause corresponding damage to the battery, reduce the service life of the battery, compared with charging every day, or charging every day, the damage to the electric vehicle is less.
2. Avoid vulcanization due to low battery voltage
Lead-acid batteries have a weakness, if they run at low voltage for a long time, then vulcanization may occur, because when using the battery, the voltage will decrease, sulfate ions will adhere to the lead plate, and if the voltage is too low for a long time, crystallization will be formed, which is the sulfidation phenomenon of the battery.
Therefore, charge the battery every day, so that the voltage will not be reduced, the crystallization of the battery plates will be avoided, the battery will not be vulcanized, and the service life of the battery can be prolonged.
The disadvantages of electric vehicles "charging every day".
Above we shared the benefits of charging electric vehicles every day, but charging electric vehicles every day, will it hurt the battery?
1. It's too troublesome to charge every day
When charging an electric vehicle, you need to connect the battery and the power supply, and after charging, you need to unplug the charger again, which is indeed very troublesome if you operate like this every day.
2. Charging every day may make the battery lack water
When the charger is used to charge the battery, there will be a chemical reaction, which will generate heat, if the heat is too high, it will evaporate the water in the electrolyte, so charging every day may cause the battery to lack water, which can affect the service life of the battery.
3. Charging every day will waste the number of charge and discharge cycles
The number of charging and discharging cycles of the battery determines the service life of the battery, although the number of charging and discharging cycles refers to the process of charging by 100% ~ 0%, which has nothing to do with the charging times of the battery, but in fact, charging the electric vehicle every day must be charged once than three or four days, which has a greater impact on the battery.
Tell you the correct charging method
Through the above analysis, we can see that charging electric vehicles every day will have benefits and disadvantages for the battery, so how to charge is the correct charging method?
1. If you use a lithium battery, instead of a lead-acid battery, then according to the user's personal Xi, you can charge it every day, or you can wait for the power to run out and then charge, which has little impact on the battery.
2. If the battery capacity used is relatively small, for example, it can only run 40 kilometers after being fully charged, and the user needs to run about 20 kilometers a day, then it needs to be charged every day, otherwise it will affect the normal use of the second day.
3. If the battery capacity is large enough to be used by the owner for 3~4 days, then wait until the power drops to 20~30% before charging, which has the least impact on the battery.
Summary:
Above we have analyzed the advantages and disadvantages of charging electric vehicles every day, it can be seen that charging every day has an impact on electric vehicles, generally speaking, it is not recommended that you charge every day, unless the power is not enough to use on the second day, which can not only extend the service life of the battery, but also do not bring trouble to life, and will not bring harm to the battery. So, what do you think about this? #文章首发挑战赛#
