Nowadays, electric cars have become the primary means of transportation for many people. Because they are practical and environmentally friendly, they drive electric cars every day. However, many people don't know three little secrets about electric car batteries. The key to whether an electric car is good or not lies in the quality of the battery of the electric car, so how to distinguish the quality of electric vehicle batteries? Just look at these points and you won't need to replace the battery for many years of driving. Come and take a look
1: Look at the outer packaging
Check if. the outer packaging of the electric vehicle battery is damaged or damaged. If there are traces of disassembly, open the package and look at the appearance of the battery. Check if there are scratches or scratches on the surfacee and if there is rust on the battery. positive and negative metal terminals of the battery
Two: Look at the anti-counterfeiting label
When the electric vehicle batteries leave the factory, an anti-counterfeiting label will be affixed to gasket. of the battery case. When purchasing, you should check whether the anti-counterfeiting label is intact. You can also scratch the password coating of the anti-counterfeiting label to verify authenticity.
Three: Check if there are any. Bulges in the case
The new electric vehicle battery case is very smooth. If you notice any irregularities in the case, you need to be careful. You can find a table or floor with a horizontal surface. side of the battery face down. If the battery can spin, it means it is not discharged and it is an old battery.

The importance of lithium battery testing, why should lithium battery testing be carried out? With the widespread use of lithium batteries in mobile communications, electronic devices and other fields, safety accidents involving lithium batteries are frequently revealed. For many electronics manufacturers, testing lithium batteries has become a daily task, and there are many reasons for this work. Therefore, testing battery performance through a standard system is the way to determine whether the battery is safe and reliable.
The importance of lithium battery testing
1. Avoid safety accidents such as explosions caused by lithium battery abuse
The emergence of lithium batteries has posed great challenges. for many electrical manufacturersonic, it brings great convenience, including the universal use of various rechargeable batteries. However, the use of these batteries has also caused many accidents, partly because detection of lithium batteries is not in place. Lithium battery testing will have specific temperature reports and appropriate environmental storage reports, from which the correct usage of the battery can be obtained.
2. Extend the life of lithium batteries
Lithium battery testing services provided by professionals in the market perform high-level simulation tests to determine the life of the battery, including including the current during charging. and storage environment, but also the extent to which the user uses the battery. Lithium battery detection can detect the battery capacity value and remind the userUser to pay attention to its saturation during charging. This can effectively extend the life of many manufacturers when manufacturing products.
3. Performance testing clarifies the direction of use
Lithium batteries are used in major production of electronic and electrical appliances, and it can be said that they can be seen everywhere in life. A company specializing in lithium battery testing will distinguish the ranges applicable to different battery types and answer any questions about usage limits. Lithium batteryFor a durable product, determining the direction of use can reduce many unnecessary costs. This is also one of the important aspects of lithium battery testing.
The importance of lithium battery testing can be summarized in the above aspects. Inspection of lithium battery safety issues can reduce the soccurrence of accidents. Lithium battery detection also includes battery flow and capacity, which can effectively extend the life of electronic products. Another important thing is that lithium batteries have a wide range of uses, and the specific usage area can be clarified after testing.
Why do we need to test lithium batteries?
1. Adhere to the recycling concept of green environmental protection
Although lithium batteries have brought many benefits to people's lives, it cannot be ignored that many elements in the battery have a negative impact. on soil and water quality, it also has a significant destructive effect on the ecological environment. Through lithium battery testing, the remaining electricity can be recycled several times, and then through a series of improvement works, electromagnetism canreborn. Lithium battery testing is a task advocated by the modern concept of green production and a necessity for the entire industrial chain.
2. Provide consumers with better after-sales protection
You should know that lithium battery testing services are aimed at many electronic manufacturers, but the actual targets of the services are mainly consumers of electronic products. . It is often thanks to the excellent lithium battery testing service that consumers achieve product recognition. Regular testing of lithium batteries in electronic equipment can also eliminate safety risks the first time and provide market consumers with better after-sales battery maintenance. with tests.
3. Reduce battery production costs and save expenses
Li-battery productionthium contains elements such as lithium alloys and lithium alloys. These items are not only complex in the production process, but also very expensive. price. Professionally provided lithium battery testing continues to reduce battery usage and production costs, paying attention to battery saturation and capacity utilization. After testing, we can clearly identify battery problems and provide quick solutions, saving most businesses money.
The reason why many electronics manufacturers carry out testing on lithium batteries is to test the concept of green environmental protection and promote the efficiency of battery recycling. It is also because the heart of electronic products is the battery and most consumers focus on the quality of service.e after-sales of the battery. Another reason is that the production of lithium batteries can reduce battery production costs, thereby reducing manufacturers' production costs and battery costs.
What are the test items for lithium batteries?
In order to ensure the safety of lithium-ion batteries, domestic and foreign institutions have formulated corresponding safety testing standards for various lithium-ion batteries. General testing standards generally divide security test items into the following four categories:
1. Electrical tests: overcharge, overdischarge, external short circuit, forced discharge, etc.
2. Mechanical testing: extrusion, acupuncture, impact, vibration, dropping, etc.
3. Thermal test: high and low temperature cycling, combustion, microwave heating, etc.
4. Environmental simulation: high altitude and low pressure simulationion, salt spray test, etc.
Extrusion, acupuncture, impact, vibration, dropping, combustion, high altitude and low pressure testing all require professional testing and battery testing machines to To ensure the safety performance of the battery, unqualified batteries are. checked to prevent battery safety accidents from occurring.
Summary: The above is the importance of lithium battery testing. Generally speaking, power lithium batteries have higher requirements for "quality and safety, product consistency and subsequent maintenance costs". , therefore the detection of lithium batteries is particularly important.
