The popularity of electric vehicles has brought great changes to the way we travel, but while enjoying convenience, we also need to pay attention to the correct charging method. Many people have a misunderstanding when using electric vehicles, that is, they have to charge electric vehicles every day, which will actually cause certain damage to the battery and even affect the service life of the battery. So, how often is it best to charge an electric car?Next, let's take a look. At present, electric vehicles mainly use lead-acid batteries and lithium batteries.
For lithium batteries, it is okay to charge at any time, whether it is "one charge per day" or "one charge every three days", it is no problem. In the case of lead-acid batteries, we can determine the optimal charging time based on the range and remaining charge. First of all, judge according to the cruising range: for example, if your electric car has a range of 60 kilometers and you use the electric car to drive about 15 kilometers a day, then "one charge in three days" works best.
Secondly, judging according to the remaining power: it is best to charge about 20% in summer, and about 30 or 40% in winter. Charging the EV battery through the above methods can not only reduce the damage to the battery, but also will not affect daily travel. Therefore, there is no need to deliberately recharge every day. In fact, "one charge a day" will bring the following four consequences: first, not only is charging troublesome, but also wasted money. Charging an electric vehicle every day will not only increase the number of charges, but also waste electricity bills.
Charging at charging stations is charged on a time-by-time basis, and if an electric vehicle is charged every day, it may only take a short time to fully charge, which will be a waste of money every day. Secondly, overcharging for a long time causes the battery to "lose water". Prolonged overcharging will cause the decomposition of the electrolyte, which will lead to the loss of battery electrolyte, which will seriously affect the performance and service life of the battery. In addition, frequent charging will lead to crystallization inside the battery, which will affect the charging and discharging efficiency of the battery and accelerate the aging of the battery.
Finally, overcharging can cause the battery to heat up, which in turn can lead to safety hazards. Therefore, the correct charging method is very important to prolong the service life of the electric vehicle battery and ensure driving safety. We should determine the frequency of charging according to the actual situation, avoid the misunderstanding of "one charge per day", so as to better enjoy the convenience brought by electric travel. The correct posture of electric vehicle charging The charging time of electric vehicles is generally about 6 to 8 hours, and it is the best choice to charge at night and unplug the power the next morning.
However, if the battery has a lot of power left and can be fully charged in 2 to 3 hours, then keeping it charged all the time may lead to overcharging, causing the water in the electrolyte to evaporate, which in turn will cause the problem of "water loss", reduce the charge and may cause the battery to bulge and deform. In addition, daily charging may also lead to voltage backlog, which will crystallize on the battery plates in the long run, affecting the charging efficiency, reducing the amount of charge charged, causing irreversible damage to the battery, and then affecting the battery life.
Even if daily charging has little effect on the number of charging and discharging cycles of the battery, "one charge per day" will waste the number of battery cycles compared to "one charge every few days", thereby shortening the service life of the battery. To sum up, although electric vehicle charging seems simple, many car owners may have misunderstandings, especially "one charge a day" car owners, this behavior may bring a series of consequences to electric vehicles, and in serious cases, it will affect the service life of the battery. Therefore, choosing a charging method that suits you can effectively extend the life of the battery.
The specific optimal charging time can be judged according to the type of battery, for example, lithium batteries can be charged at will, while lead-acid batteries can be charged according to the remaining power or mileage of the battery. I hope that car owners can understand this and make an informed choice.
