Hygrothermal test The wet thermal test simulates the impact of wet and high temperature environments on batteries, and is especially suitable for use in high-humidity areas such as tropical and coastal areas. Through the test, you can verify the structural stability and tightness of the battery in a high humidity environment to ensure that it will not cause performance degradation…
High and low temperature test The high and low temperature test can simulate the extreme temperature conditions that the battery may experience in practical applications, and verify whether the design and material of the battery have good thermal stability and cold resistance. Through testing, to ensure that the battery can still maintain stable performance in cold or hot environments, and…
Environmental adaptability test Environmental adaptability testing includes high and low temperature testing, wet and heat testing, vibration testing, drop testing and salt spray testing to comprehensively evaluate the performance and safety of the battery under different environmental conditions. High and low temperature tests verify the battery’s stability at extreme temperatures, wet and thermal tests assess its durability in wet environments,…
Product testing Product testing is a key link to ensure that the battery and its packaging can play a stable and safe performance in actual use. Through a series of different types of tests, the battery’s electrical performance, safety, environmental adaptability and other aspects can be comprehensively evaluated to ensure that it meets national standards and industry norms, meets customer…
Electrical performance test Electrical performance test is a key link to evaluate the electrical characteristics of battery such as energy conversion efficiency, energy storage capacity and working state during use. By measuring the different electrical properties of the battery, it is ensured that the battery can provide the required power for the equipment stably and maintain a good working state…
Capacity test Capacity testing is one of the core tests to evaluate battery performance and is used to measure the maximum amount of power a battery can provide under specified charge and discharge conditions, usually in milliampere-hours (mAh) or ampere-hours (Ah). By charging and discharging the battery, you can determine the effective energy that the battery can provide during use,…
Internal resistance test The Internal Resistance test is one of the important indicators to evaluate the performance of the battery. Internal resistance (IR) is the obstruction of the current flow inside the battery, which affects the efficiency, power output and heat generation of the battery. The greater the internal resistance, the battery will generate more heat when discharging, the discharge…
Open circuit voltage test Open circuit voltage test is one of the common and basic test methods in battery performance evaluation, mainly used to measure the voltage value of the battery in the case of no load (that is, no current flow). By measuring the open circuit voltage, you can know the health of the battery, the level of charging,…
Magnification performance test The Rate Performance Test is a key test to evaluate the performance of the battery at different discharge rates, which is used to determine the performance of the battery under high power requirements. C-rate indicates the rate at which a battery discharges, usually expressed as a multiple of the battery capacity. For example, 1C means that the…
Self-discharge test A self-discharge test evaluates a battery’s ability to naturally lose charge over a period of time when not in use. The self-discharge rate of a battery is the rate at which the energy stored in the battery is gradually lost over time without an external load. The purpose of the self-discharge test is to check the energy storage…
