1. Don’t use fast charging stations to charge
Normally, the charging time of lead-acid battery is 6 to 8 hours. Some car owners think that the charging time is too long and will choose to use fast charging stations to charge electric vehicles. In fact, this approach is wrong. Regularly using fast charging stations to charge the battery will affect the service life of the battery. The working principle of the fast charging station is to increase the charging current of the battery and charge the battery more power in a short period of time. However, we know that the lead-acid battery does not support fast charging. Excessive current will cause impact on the battery's plate, and may even break down the plate, causing irreversible damage to the battery.
Even if graphene battery and lithium batteries support fast charging function, electric vehicles must also support BMS battery protection function, and also have corresponding matching current, that is, it is best to use the fast charger that comes with the electric vehicle, so as to ensure that the battery is not damaged.
2. Don’t not charge for a long time
Some car owners believe that since lead-acid batteries have a limit on the number of charges, they can not charge the electric vehicle when they are not using electric vehicles to reduce the number of charges. In fact, this approach is also wrong. Not charging the battery for a long time will also affect the service life of the battery.
Nowadays, most electric vehicles use ordinary lead-acid batteries. Even when they are not in use, they still have self-discharge. Over time, it will cause a decrease in the battery capacity, and even the battery will have sulphide , which will cause a decrease in capacity, a decrease in range, and even shorten the battery's service life.
In addition, lithium batteries should not be charged for a long time. Although lithium batteries do not have self-discharge, lithium batteries will also be dormant if they are not charged for a long time, so the battery must be charged regularly. If the electric car is not used for a long time, the lead-acid battery is generally charged once a week, and the lithium battery can be charged once a month.
3. Don’t use inferior chargers
When charging electric vehicles, you have to use a charger every time. Therefore, the advantages and disadvantages of the charger will affect the service life of the battery. A inferior charger will not only damage the battery, but may also pose safety hazards.
charger converts alternating current into DC to charge into the battery. In order to save costs, some inferior chargers do not use temperature control devices, and even save voltage stabilization chips. This will cause current fluctuations and fluctuations, which will not only affect the normal charging of the battery, but will even cause damage to the battery plate.
In addition, inferior chargers may also have disadvantages such as low conversion efficiency and large heat generation. On the one hand, they will waste more electricity, and on the other hand, they will have safety hazards, and may cause the charger to catch fire. So when we charge electric cars, we must not choose inferior chargers.
Summary:
When using an electric car, you need to charge the battery. When charging, you must do the above three things. This can protect our battery well. The service life of the battery can be long, and it can allow your battery to use for two more years.
So, what other issues do you think should be paid attention to when charging an electric car? Everyone is welcome to leave comments.
