Firstly, let's take a look at the types of electric vehicle batteries. Currently, there are two important types: lead-acid batteries and lithium-ion batteries. Due to the lack of memory effect in both types of batteries, many users believe that these electric vehicle batteries can be charged and discharged at any time. However, in fact, these users have overlooked one thing, which is that both lead-acid batteries and lithium-ion batteries have a certain number of charging and discharging cycles. This means that the higher the charging and discharging frequency, the shorter the battery life.
Taking lead-acid batteries as an example, their complete charge and discharge cycles are only about 360 times. Simply put, if an electric car is charged every 3 days, the battery can last for about 3 years or more. If charged every 1 to 2 days, the theoretical lifespan is less than 3 years. Therefore, if the electric vehicle battery is unplugged before it is fully charged, it is equivalent to consuming one charge and discharge cycle, and it can be seen from this that unplugging the electric vehicle battery before it is fully charged will affect the battery.
Secondly, during the charging process of electric vehicle batteries, a large amount of heat is released, which causes the battery to rapidly heat up. And when fully charged, the battery will gradually return to normal. If the plug is unplugged before being fully charged and the electric vehicle is ridden out directly, the temperature will become higher after the electric vehicle runs, which will also accelerate the rate of battery dehydration and reduce the battery life of the electric vehicle.
In short, unplugging an electric vehicle battery before it is fully charged can affect the battery's lifespan. Although the impact may not be significant in the short term, it will increase over time. Therefore, for users, unless there is anything special, try to avoid using this charging method as much as possible.
Finally, some users may ask: How should electric vehicle batteries be charged correctly? In fact, as long as the charging time is controlled at around 8 hours, and after being fully charged, it can continue to float charge for half an hour, which is more conducive to fully charging.
In addition, remember to prevent mixing chargers;
