Electric vehicles are very convenient and practical means of transportation, but people have been dissatisfied with the battery of electric vehicles, on the one hand, the mileage is short, there is a situation that does not run far, on the other hand, the service life is short, and it needs to be replaced in 1~2 years. If you want the electric car to be more durable, don't choose these 3 kinds of batteries, and meet the requirements of "4 don'ts" when charging, let's find out!
If you want an electric car to be more durable, don't choose these 3 types of batteries
The battery is the core component of the electric vehicle, because the battery is the energy source of the electric vehicle, all the power is stored in the battery, if the electric vehicle can be more durable, then when choosing the battery, these three types of batteries must not be selected.
Type 1: Inferior miscellaneous batteries
At present, there are many brands of electric vehicle batteries, and the quality is also uneven, especially lead-acid batteries, due to the relatively simple manufacturing process, some small workshops can be produced, these batteries may have little impact at the beginning of use, but due to insufficient materials, cutting corners and other reasons, the battery will appear after half a year of power shortage, and the battery life is not far away.
Therefore, when buying an electric vehicle battery, you must choose a big brand battery, so that you can have quality assurance, and don't choose an inferior battery for the sake of being greedy and cheap.
Type 2: Aftermarket batteries
In addition, when replacing the battery, do not choose after-sales batteries, although these after-sales batteries are also from regular manufacturers, but their quality is not guaranteed, mainly used as a replacement battery for customer after-sales service, generally can only be used for about half a year.
The distinction of after-sales batteries is also relatively simple, generally printed on the surface of the battery with the words non-sale, after-sales special, etc., or on the battery cover with a laser engraved after-sales, turnover logo, so when choosing a battery, you must carefully check whether the battery is in breach of contract compliance type, and at the same time to check the production date of the battery, do not choose a battery with too long inventory time.
The third type: lead-acid to lithium battery
When some users buy an electric vehicle, they want to replace the original lead-acid battery with a lithium battery, which can make the electric vehicle lighter and speed up the charging time of the electric vehicle, but this replacement of the battery not only has a safety risk, but also affects the service life of the battery.
Because the electric vehicle with the original lead-acid battery is not equipped with a battery management system, it is very likely that there will be overcharge, overdischarge or overheating of the battery, which will have potential safety hazards, and may even catch fire and explode.
Charging also needs to meet the "4 don't" requirements
After choosing a qualified battery of a big brand, we should also pay attention to charging, the correct charging method can extend the service life of the battery, as the saying goes, the battery is charged badly, not with a bad one, so charging is very important for the battery, and it is necessary to meet the requirements of "4 don't" when charging.
1. Do not charge in harsh environments
The best working temperature of the battery is about 25 degrees, so try to charge it in a ventilated and dry environment that keeps it at room temperature as much as possible, and does not charge it in a cold or overheated environment, which will affect the charging efficiency of the battery.
2. Don't charge for a long time and don't pull out the power supply
Under normal circumstances, the electric vehicle battery needs 6~8 hours to be fully charged, the specific charging time can be checked in the charger's manual, or after the charger jumps the green light, and then float for about 30 minutes, it is necessary to unplug the power supply in time, do not charge for a long time, so that it is very easy to overheat the battery and bulge deformation.
3. Don't make a mistake in the order of plugging and unplugging the charger
Electric vehicle charging, seemingly a simple operation, only need to connect the charger to the power supply and the electric vehicle battery, but you must pay attention to the plugging and unplugging order of the charger, if you get the wrong plugging and unplugging order, it may affect the service life of the battery.
When charging an electric vehicle, you must first plug in the battery and then plug in the power supply, after it is fully charged, when you pull out the electric vehicle charger, you must first unplug the power supply, and then pull out the battery.
4. Do not recharge when the battery is too low
At present, most electric vehicles are equipped with lead-acid batteries, in the process of use, do not wait until the power is too low to charge, under normal circumstances, the power is less than 30% to charge in time, so as not to damage the battery. Of course, if it is a lithium battery, it can be charged at any time.
Summary:
The battery is the core component of the electric vehicle, if you want the electric vehicle to be more durable, then you should pay attention to the replacement of the battery, do not choose three kinds of batteries, respectively, inferior miscellaneous batteries, after-sales batteries and lead-acid lithium batteries, even if you choose a qualified battery of a large brand, you must meet the requirements of "4 don't" when charging, so as to make the battery more durable. So, what do you think about this?
