1. The constant voltage and constant current charging is safe and smooth, and the voltage and current sampling output of the device is controlled through the four-wire system connection for soft start, so as to make a safe and smooth transition in the constant voltage and constant current charging process to avoid the occurrence of peak damage to the battery.
2. Each CH can perform constant current and constant voltage charge and constant current discharge test on the 512 Cells that meet the voltage range.
3. Using the constant current-constant voltage power supply of the invention patent, there is no impact from constant current to constant voltage switching, which is especially suitable for the requirements of lithium ion battery charging.
4. Equipment and computer interface: the Ethernet interface between the equipment and computer can ensure the stability and real-time of remote data acquisition, and the operation of the equipment can be activated by the office network and remote monitoring workshop in real time.
5. Each battery fully has its own constant current and constant voltage source, and its own loop does not affect each other.
6. Real-time detection of each cell's voltage, charging, the first constant current charging, when the battery voltage reaches the set value, will be smoothly transferred to constant voltage charging, to meet the set time or current termination conditions, the charge is over. During constant current discharge, when the battery voltage is lower than the set value, the discharge is completed and the corresponding battery indicator lights up.
7. Multiple conditions (capacity, time, open circuit voltage, discharge platform, etc.) for battery sorting.
8. Automatically calculate the constant current charge ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data.
9. This equipment is to test battery charge, discharge and related characteristics. Through software programming, the operator can charge and discharge the battery with any current or voltage within testing range.
10. Curve analysis and processing: curve analysis function. Can flexibly select the cycle that needs to be displayed, a variety of curve combinations (such as voltage, current, capacity- time; capacity-voltage; cycle times-charge-discharge end voltage and etc.); Graphics can be arbitrarily moved, horizontal/longitudinal magnified or reduced to check the voltage, current, capacity, cell voltage and other data details. Can compare one data file for different cycle data or compare several data file curves at one time.
