Regular testing of lithium batteries in electronic equipment can also eliminate safety risks at the first time and provide consumers in the market with better battery maintenance and after-sales service. . test.

3. Reduce battery production costs and save expenses

Lithium battery production contains elements such as lithium alloys ands 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 core of electronic products is the battery, and most consumers focus on the quality of battery after-sales service. Another reason is that the productivityon lithium batteries can reduce the production costs of batteries, thereby reducing the production costs of manufacturers and the costs of batteries.

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 simulation, salt spray test, etc.

Extrusion tests, acupuncture, impact, vibration, dropping, burning, high altitude and low pressure all require professional battery testing and testing machines in order 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.

What is the maximum temperature that lithium batteries can withstand?

Lithium battery testing system can test according to the values ​​that need to be tested. It depends on the lithium battery you are mainly testing, including coincluding voltage, current and capacity. Maximum current. Temperature, charge and discharge rate...etc. Generally, there are dozens of high-precision articles...

What does the cycle performance of a 1c lithium-ion battery mean?

< p >Mobile general The temperature limit of the phone's lithium battery is 40 degrees Celsius, 40-60 degrees Celsius. If the time is not too long, there will be no problem. Lithium batteries can also be specially customized to withstand high temperatures, and their high temperature performance will be much better.

Lithium battery for mobile phoneThe set temperature limit is generally 40-60 degrees, and the battery is usually marked with an explosion-proof valve, while high temperature resistant lithium batteries can withstand severe temperatures up to 800 degrees. Generally, batteriesLithium batteries are tested to withstand high temperatures of 200 degrees, 500 degrees and 800 degrees, but they are generally not exposed to such high temperatures in daily life.

For lithium batteries, there is currently no clear theory in the industry to support the inevitable relationship between internal resistance, discharge platform, life, capacity, etc. under various temperature performance. Calculation formulas and relevant mathematical models. are still under study. Generally speaking, lithium batteries are not sensitive to temperatures between 0 and 40°C. However, once the temperature exceeds this range, the lifespan and capacity will be compromised.

To ensure the lifespan, safety and reliability of lithium batteries, advanced protection management systems are used in resistive lithium battery packs.nts at high temperatures to prevent overcharge, overdischarge, high temperature operation and low temperature. temperature charging or short circuit be damaged or even cause safety problems.

Detailed information:

< p>Be sure to pay attention to the following points when purchasing.

1. Is the capacity clearly marked? Batteries without clearly marked capacity (such as 1000 mAh or 1000 mAh) are most likely using lower quality batteries or recycled batteries. Many inexpensive batteries on the market are made from recycled batteries. Although they are cheap, their lifespan is short and their unstable quality can damage the phone.

2. Is there guaranteed standby time? Standby time is the duration of continuous use since thetime the battery is installed in the phone until the next charge. Generally, batteries sold in the market cannot guarantee standby time to customers. This is because the battery quality is unstable. Many cheap batteries use poor quality battery cores, so the standby time is very short.

3. Whether to install a safety protection circuit board. Without a protective circuit board, the lithium battery may deform, leak and explode. Faced with fierce competition for lower prices, each company searches for cheaper protective circuit boards or even omits this device, leaving the market flooded with lithium batteries that are at risk of exploding. Consumers cannot determine whether there is a protective circuit board from its appearance, so it is better to choose a reputable trader to purchase it.

C reprepresents the discharge rate. How many C is the capacitance times how much. Batteries are divided into high-rate batteries. High rate batteries can be discharged above 10°C. Ordinary batteries can only be discharged in 1 hour, 2°C in 0.5 hours, and 0.5°C in 2 hours. The discharge current, the longer the discharge time. Cycle performance refers to the lifespan of lithium-ion batteries.

Lifespan, charge and discharge rate, internal resistance, capacity, etc. Cell phone lithium batteries must all be tested. The shrapnel microneedle module of the battery test module can be used to connect signals and transmit current. , which is beneficial to improve the testing stability of mobile phone batteries., can maintain stable transmission in the current range of 1-50A, with high reliability.
