Electric vehicles as a popular means of transportation, many people are complaining about its endurance problems, indeed, the current technology of electric vehicle batteries still need to be broken, its endurance is not high, it does make many people very headaches, especially after the endurance of the space, the battery life will appear seriously declining, even if it is a new battery, there will be such a problem, then, the newly bought battery, there will be a serious decline in endurance, it is necessary to consider 3 aspects of the factors;
The first aspect: electric vehicles are affected by the ambient temperature, the optimal temperature of the battery charge and discharge is 25 ° C, too high temperature will cause the battery to overheat, resulting in water loss, will also affect the endurance, but it is not immediately effective, generally immediate endurance will become lower, because the temperature is too low, too low temperature will affect the efficiency of battery charge and discharge, affecting the battery life, if it is because of this reason, as long as the weather temperature is normal, the battery will restore endurance.
The second aspect: the replacement battery is not selected the right battery model, if the battery model is selected wrong, it will lead to a mismatch between the battery and motor power, the situation of "small horse-drawn cart", then, its endurance will drop very seriously, such a situation, you need to change the battery, through the old battery plastic shell or the original charger parameters, to verify whether the original battery model and the battery model to be replaced are consistent.
The third aspect: This is also a point that many car owners are more worried about, afraid of replacing themselves with renovated, second-level, third-level fake batteries, in this case, the battery life decline is irreversible situation, small connoisseurs also for this problem, to share 3 quickly distinguish the original battery and refurbished battery dry goods knowledge, the key time is very useful.
Trick 1: Look at the outer packaging of the battery
The outer packaging of the battery will give an intuitive judgment, the general regular brand of batteries, the outer packaging will clarify the signal, date, level and other information of the battery, if the battery is a second-level, three-level after-sales, turnover battery, can be identified at a glance.
For the judgment of the refurbished battery, if the outer packaging is not clear, altered, wrinkled, polished, etc., and the general battery is within 3 months, normal storage can not appear such a problem, if there is this problem, it means that the outer packaging of the battery is not original or has been used, the battery inside is bound to be not the original new battery, the probability is that the after-sales battery, or even the refurbished battery of the small workshop.
Trick 2: Look at the plastic casing of the battery
Battery packaging "cheating" is very easy, after all, the merchant can not put the outer packaging directly to the owner to see, can not be judged by the outer packaging, but the battery shell, the owner is bound to see, in general, the original battery plastic shell, smoothness and brightness are very good, the appearance will not have any traces.
And if the plastic shell of the battery, there is no smoothness to the touch, because through the grinding, the impurities and bubbles of the plastic itself will be released, and it will look like the brightness will decrease, and there will be a hazy feeling, and as long as it is a polished battery, it will naturally not be the original, and when choosing, you need to pay attention.
Trick 3: Check through the security code
This is the most direct way to identify fakes, but also the method recommended by major battery brands, you can query through the anti-counterfeiting code on the battery, obtain the battery manufacturer information, production date and other related data, and judge the true and false.
The method of inquiry is also relatively simple, the first is to directly scan the code query results, the second is to call the official phone through the 16-bit anti-counterfeiting code query, and other official website inquiries, SMS inquiries and other ways, can quickly distinguish the authenticity of the battery, but this way, limited to some large brands, small brands, miscellaneous brand batteries, is not perfect at present.
Trick 4: Check the battery's interface
The battery is composed of multiple 12V batteries, 48V by 4, 60V by 5, and between each battery, are connected by a connection line, and as long as it is connected, the vehicle is riding bumps, and the interface will appear a certain wear marks.
When the battery opens the interface, if it is a brand new battery, the interface should be new, and if there have been wear marks or even rust, then the battery may be reused by repair and refurbishment, this kind of battery, it is not recommended to choose.
Trick 5: Judge by qualification certificate
Regular brand batteries, will carry a certificate of conformity, warranty card, the certificate of conformity is to represent the battery passed the inspection, is a qualified product, and the warranty card is the battery with 6 months free replacement, 12 months quality warranty or replacement of the after-sales battery commitment, which is refurbished battery does not have.
Therefore, batteries that cannot provide certificates of conformity and warranty cards are basically either refurbished batteries or counterfeit batteries, and even if these batteries are cheap, they are not recommended to choose.
Conclusion: The above is the 5 tricks can judge the method of the battery, the small connoisseur believes that it is still necessary to pay attention to it when choosing the battery, after all, choose a counterfeit, refurbished battery, its life, endurance will be particularly poor, need to replace the battery frequently, not only costly, but also very troublesome, finally, the small connoisseur also has to remind the owner, when choosing a battery, it is not recommended to choose a battery that has been shipped for more than 3 months, which is called a stock battery in the industry, and when choosing a battery, Try to choose a brand store or a regular store choice, so that it will be more secure.
I hope the above can help you, pay attention to the electric vehicle connoisseurs, and share the information and views related to electric vehicles every day.
