Electric vehicles are currently "powered" means of transportation, according to my understanding is the mainstream model, the most affordable model, I have done such a calculation, buy an electric car + the cost of use, the cost of electric vehicles a year is about 120 yuan, which is equivalent to living in many cities, once the dinner is not needed.
The low cost of using electric vehicles is an objective fact, but as the owner of an electric vehicle, will encounter such a situation, an electric vehicle seems to always have to replace the battery once, indeed, according to the life of an electric vehicle, its frame, motor, controller and other major components, can be used for more than 5 years, and its battery life is generally 2-4 years, that means that to maximize the benefits of electric vehicles, replacing the battery is the most cost-effective way.
Often there will be car owners asked, when changing the battery, there is nothing to pay attention to, the small connoisseur today summed up the experience of changing the battery, of which, to remind that there are 3 types of battery durability is poor, low safety, the car owner learned to avoid.
Category 1: Refurbished, repaired batteries
What is the refurbished battery: I believe that many people have heard of the "refurbished machine", that is, the used mobile phone, after the refurbishment is sold again, the battery is the same, some used batteries, can be refurbished, so that its appearance and the new battery is the same, blinding the owner, and the refurbished battery has a new appearance, but the battery whether it is the number of cycles of charging, or the calendar life will be relatively short, durability is relatively poor.
What is the repair of the battery: compared to the refurbished battery is only to do enough surface work, repair the battery will be more "responsible", it is the battery inside the crystallization, vulcanization and other damage to repair, so that the performance of the battery, the capacity basically reached the new battery, but no matter how to repair, its cycle charge and discharge times are irreparable, durability is relatively poor, and through the disassembly repair of the battery, its safety is also difficult to guarantee.
Method of discrimination: The little connoisseur summarizes the identification technique as "one look, two touches, three queries";
A look: whether the appearance of the battery has polishing marks, once polished, the appearance of the battery will lose a new sense of light;
Second touch: after the appearance of the battery is polished, its smoothness will be reduced, and even the roughness of the "horn hand";
Three queries: whether it is refurbished or repaired batteries, are used batteries, the production date must not be recent, and the new battery will generally be about 1 month or less, query the production date, you can identify whether it is a problem battery.
Category 2: Miscellaneous, counterfeit batteries
What is a miscellaneous brand battery: this kind of battery was very common in the past, and now with the formation of a battery brand, it has been relatively rare, it mainly refers to some small workshops, small manufacturers of batteries, relatively large brands of batteries, their "quality control" ability is very poor, the durability of the product is poor, the safety is low.
What is a counterfeit battery: from the literal meaning can be understood, counterfeit large brand battery, this is the situation that products in all walks of life exist, such shoddy products, quality will generally not be guaranteed, durability, safety is not trustworthy.
How to identify: miscellaneous batteries are actually very simple, you can casually search for the top 50 brands of batteries on the Internet, if even the top 50 are not accounted for, you can define as miscellaneous brands, and counterfeit batteries, you can query the serial number through the official website, telephone, two-dimensional code, check no this number, it must be a counterfeit battery.
Class 3: Secondary and tertiary batteries
What is the secondary battery: it refers to the maintenance of the battery, generally only the brand will have such a battery, is not for sale, its warranty time is very short, generally only 2 months, but also shows that the durability of the battery is not good.
What is the three-stage battery: it refers to the after-sales battery, the manufacturer recycles or some defective battery products from the factory, when the owner buys a new battery beyond the free replacement warranty period, the battery given to the owner of the after-sales service, generally is a new battery after 8 months of the new battery, it is no warranty service, the battery performance in all aspects will also be discounted battery.
How to identify: these batteries are "non-selling products", is the manufacturer to identify, maintain, group the battery, before the manufacturer to the dealer, will be in the packaging shell, battery shell printed on the "non-sale" or directly marked maintenance, after-sales battery words, is to prompt the owner, do not buy such a battery, as long as a little attention, you can well identify this type of secondary, tertiary battery.
Now many car owners are accustomed to buying batteries online, such a situation, small connoisseurs are nagging a few reminders, hoping to help you
(1), choose the official self-operated store, the products of the e-commerce platform are "uneven", all kinds of merchants under the banner of the store, it is difficult to know the quality and authenticity of the product for a while, therefore, the small connoisseur suggests that the brand official self-operated store or flagship store is directly selected.
(2), choose a big brand battery, choose a big brand battery on the Internet, not only the quality is more secure, but also, now Tianneng, Chaowei battery, but also support online purchase, offline store installation, or after-sales personnel to install, very aspect.
(3), their own installation of the battery to put balance, under normal circumstances, can choose to install themselves, are with circuit common sense, there will be no wiring errors, to the small connoisseur to learn, some car owners, will be because of carelessness, put a line or other items under the battery, resulting in the battery is not balanced enough, so that in the riding process plus bumps, so that the battery contact is poor, because of the battery life, and even the occurrence of safety hazards, this point of the car main special attention.
Little Connoisseur Summary:
Through the above introduction, the summary of the car mainly learned to avoid the 3 types of batteries include: refurbished, repaired batteries, miscellaneous brands, counterfeit batteries, secondary, tertiary batteries, these batteries are not high in safety, durability is worse, and in the identification, you can see that the trustworthy battery, should have a battery is a big brand, the battery production date is less than 3 months, the battery is new These characteristics, which is also some of the bottom line requirements for choosing a battery.
When replacing the battery, if you choose to buy a battery online, although its price will be more transparent, there will be no routine, small connoisseurs are recommended to buy such a method, but try to understand the circuit knowledge or choose to pick up the goods in the offline store installation, otherwise, it is still recommended to go directly to the store to consult the maintenance master to replace the battery, to avoid because of the battery matching or improper installation operation, resulting in the battery is not durable, increasing the problem of safety hazards.
