Solution download/From battery cells to battery packs, it’s all in the ITS5300 battery charge and discharge test system

　　Scenario 1: Battery manufacturer

　　During the battery production and testing process, overcharge, over-discharge and imbalance between cells are the main factors leading to the degradation of battery life. On the other hand, with the expansion of the company's business scope, the power of battery packs is getting larger and larger. How to use existing equipment to meet high-power needs and solve the problem of high testing costs has always been a concern of battery manufacturers.

　　Scenario 2: Manufacturers of home appliances/EVs/energy storage power stations that use batteries

　　As a downstream user of batteries, when the battery is applied to actual products for testing, it may not reach the nominal lifespan. How to effectively evaluate the actual life of the battery in advance in order to select appropriate battery specifications and suppliers is the main purpose of battery user testing.

　　It can be seen that what you are concerned about during the battery test...?

　　ØHow to extend the battery life during the test?

　　ØHow to solve the high testing cost of high-power batteries?

　　ØHow to improve the utilization rate of test equipment?

　　ØHow to evaluate the actual service life based on usage conditions in the early stages of product development?

　　ØHow to quickly analyze failed batteries?

　　ØHow to obtain more intuitive data to improve battery technology?

　　ITECH battery system solves your testing difficulties and reduces electricity costs by 85%

　　#DelayBatteryLife# In order to further improve the safety and reliability of the system and avoid battery life degradation caused by misoperation, the ITECH battery testing system provides a pre-judgment function before charge and discharge tests, screening out unqualified battery packs in advance, and thus identifying internal failure orders. Body should be replaced promptly. On the other hand, for imbalances that occur during the test process, the system can cooperate with the BMS to complete the balanced charge and discharge test to avoid battery life degradation caused by overcharge and overdischarge.

　　#costandequipmentutilization#Cost has always been a matter of great concern to users, especially for high-power battery testing. According to the charging standard of 0.5 yuan per kilowatt hour of electricity, assuming an average daily consumption of 60kWh, the electricity cost will be about 30,000 yuan. ITECH provides energy-feedback solutions for testing from battery cells to battery packs. The feedback efficiency is up to 95%, which means that 57kWh of power can be fed back to the grid, greatly saving electricity costs. In addition, the system can be flexibly switched between multi-channel low power and small-channel high power.

　　#Evaluate real usage life# In real applications of batteries (such as EVbattery), as the vehicle accelerates, decelerates, idles and other working conditions, the current magnitude and direction change all the time. If the battery is installed in an actual vehicle, it is obviously inappropriate to evaluate the cruising range. Our software can truly restore real working conditions in the laboratory, simulating up to 1,000,000 current values, and the current switching time -90%~90%) is less than 2ms.

　　#batteriesperformanceandfailureanalysis# The ultimate goal of battery testing is to obtain the battery life decay rate, temperature characteristics, and rate characteristics. If the voltage-capacity curves at different temperatures are reflected in the same chart, I believe that such a display will save you time in post-processing data. In ITECH's battery solution, we help users complete analysis quickly and intuitively through the combination of statistical analysis, filtering and functions. For abnormalities during the testing process, the system can record the source of the fault and specific values in detail to facilitate traceability of the cause of the failure and subsequent improvements.
