If the electric vehicle battery is not fully charged, will it affect the battery?
In life, I believe that many users have done such an operation, that is, unplug the plug or charger before the battery of the electric car is fully charged. In this regard, some users have this question: Will this affect the electric vehicle battery?
First of all, let's take a look at the types of electric vehicle batteries. Currently, there are mainly two types of lead-acid batteries and lithium batteries. Since neither of these two types of batteries have a memory effect, it seems to many users that this type of electric vehicle battery can be charged and discharged at any time. However, in fact, this part of users has overlooked one point, that is, both lead-acid batteries and lithium batteries have a certain number of charging and discharging, which means that the higher the charging and discharging frequency, the shorter the battery life.
Take the lead-acid battery as an example, the number of complete charging and discharging is about 360 times. To put it simply, if an electric car is charged every 3 days, the battery can be used for more than 3 years. If charging is performed every 1 to 2 days, the service life is theoretically less than 3 years. Therefore, if the electric vehicle battery is not fully charged, it is equivalent to one charge and discharge times. From this, it can be seen that the electric vehicle battery is not fully charged and the plug is unplugged will affect the battery.
Secondly, a large amount of heat is released during the charging of the battery of an electric vehicle, which causes the battery to heat up rapidly. When it is fully charged, the battery will gradually return to normal. And if you pull the plug when it is not fully charged and ride out directly, the temperature will become higher after the electric vehicle is running, and this time will also accelerate the speed of battery loss and reduce the battery life of the electric vehicle.
In short, if the electric vehicle battery is not fully charged, it will affect the battery life. Although the impact may not be obvious in the short term, the impact of such operation will increase for a long time. Therefore, for users, if there are no special things, try to avoid using this charging method.
Finally, some users may have to ask: How to charge the battery of an electric car correctly? In fact, you only need to control the charging time to about 8 hours, and after being fully charged, you can continue to float for half an hour, which is more conducive to full charging.
In addition, remember to avoid mixing chargers;
Also avoid using high-power charging such as fast charging.
