Battery Formation And Grading System Application
Battery formation and grading system (battery cell capacity grading machine) is used for lithium polymer, lithium ion, NiMH, NiCd battery chemical composition and testing, as well as cycle life testing equipment.
Hardware Features
(1) Battery test channels: each channel can be a group of finished batteries for battery performance testing, a single test channel using modular combination, each module can be individually current limit, so that users feel convenient when expanding the channel and maintenance equipment. Each channel is completely independent, do not interfere with each other, do not affect each other, even if for some reason the individual channel does not work properly, will not affect the normal work of other channels.
(2) Battery fixture: Each battery fixture is designed using the international popular four-wire system principle, which avoids superimposing the internal resistance of the tester on the internal resistance of the battery and makes the test results more accurate. The fixture has beautiful appearance, strong corrosion resistance, easy adjustment and reliable contact.
(3) Test data and state power-down protection: the test equipment has power-down protection function, through the upper computer software selected this function, when the power supply suddenly stops, it can rely on its own dry battery to save the recorded data, when the power supply resumes, it can also restore the state of power failure and continue to run.
(4) Thoughtful and flexible software and hardware safety protection: software protection: when the battery under test has low voltage, low current, over voltage and over current, the control system will close this channel and disconnect this battery from the equipment. Fixture safety protection: All battery fixtures and accessories are made of flame retardant materials.
(5) Cooling method: air cooling.
Software Introduction
(1) Programmable battery charging and discharging mode can independently control each channel charging and discharging: independent programming control of each charging and discharging channel, programming content: constant current charging, constant current discharging, constant voltage charging, constant power charging, constant power discharging, constant resistance charging, constant resistance discharging, resting, cycling and other work steps (work steps). Limiting conditions can be set for each work step, and for different charging and discharging methods, there can be different limiting conditions, such as time, voltage, capacity, negative slope, etc. There is a logical or relationship between various restriction conditions, when any one of the restriction conditions is satisfied, it can go to the next work step or stop. After the user sets the battery charging and discharging program by computer, as long as the channel is started, the test system will execute the setting process completely automatically without human intervention, and the data (voltage, current, capacity, and relative time status) can be displayed in real time, meanwhile, the test system will record all the relevant data during the whole test process according to the recording mode and recording parameters set by the user, such as: time The test system will record all relevant data during the whole test process, such as: time, current, voltage, capacity, voltage of each single cell, temperature of each single cell, etc. For each independent channel, Hongda battery compartment cabinet has its own large-capacity test data cycle memory.
(2) Powerful data processing function This software has data analysis (curve, graph, etc.), data transfer and conversion EXCEL function, curve types are: voltage ---- time, current ---- time, capacity ---- time, capacity ---- times.
(3) Advanced curve processing and comparison functions, this software provides the current and voltage curves of different channels in the same coordinate system, the user can intercept and enlarge the curve according to the need, so that the small differences between different performances can be controlled optimally, greatly improving the efficiency and shortening the cycle of experimental results.
