Battery is the main source of power for products, which can drive the operation of equipment. Detailed testing of the battery using testing tools can ensure its safety and prevent spontaneous combustion and explosion caused by excessive temperature. Cars are the main means of transportation for everyone and are used frequently. Therefore, in order to ensure the safety of drivers, battery testing is imperative. The testing method is to simulate various accident situations, Judging whether the quality of the battery is qualified, observing whether the battery will explode, and using these tests can effectively avoid risks and maintain stability.
1. Cycle life
The number of cycles of a Lithium Battery reflects how many times the battery can be repeatedly charged and discharged. According to the different environments in which Lithium Batteries are used, the cycle life can be tested to determine how much the battery can achieve at low temperature, room temperature, and high temperature. The standard for battery disposal is usually selected based on the purpose of the battery. If the battery is used for power batteries (electric vehicles, electric forklifts), etc., a discharge capacity maintenance rate of 80% is generally chosen as the standard parameter for disposal. However, if the battery is used for energy storage, energy storage, etc., it can be relaxed to 60%. If the discharge capacity/initial discharge capacity of the battery that we often come into contact with is less than 60%, it is no longer necessary to use it and cannot last for half a day.
2. Magnification
Nowadays, Lithium Batteries are not only used for 3C, but also increasingly used in power batteries. Electric Bicycles need to change the current when driving under different operating conditions.
3. Safety Q integrity testing
Security and safety are issues that battery users are very concerned about, whether it is the explosion of mobile phone batteries or the ignition of Ncm E Bikes , which are enough to make people tremble and tremble
4. Discharge at low temperature, discharge at high temperature
The impact of temperature on the discharge performance of batteries is directly reflected in the discharge capacity and discharge voltage. As the temperature decreases, the internal resistance of the battery increases, the electrochemical reaction speed slows down, and the polarization internal resistance rapidly increases. The discharge capacity and discharge platform of the battery decrease, affecting the output of battery power and energy.
