Sodium Ion Battery 512 Channel Formation And Grading Tester

1. Basic Composition of Equipment

The equipment is mainly composed of computer, communication interface and battery detection cabinet. The battery detection cabinet is composed of a clamp and a board body for placing the clamp, a constant current and constant voltage source, a storage control circuit, a sampling circuit, a single chip microcomputer and a control panel.

(Battery Tester can be used for cylindrical, pouch and prismatic cell.

Optional: Battery tester with tray loading and Energy feedback function.)

2. Main Performance of Equipment

1) Each device can conduct constant current and constant voltage charging and constant current discharge tests on 512 batteries that meet the voltage range.

2) The constant current constant voltage power supply with invention patent is adopted, and the switching from constant current to constant voltage has no impact. It is especially suitable for the charging requirements of lithium-ion battery.

3) The equipment adopts AVR single-chip computer as the control center and cooperates with the peripheral sampling circuit. It can be controlled by the superior computer. When the computer is connected to work, it can save the complete charge discharge curve of all channels, or it can be separated from the superior computer and operate through the control panel to complete constant current and constant voltage charging, constant current discharge test, sorting according to time, etc.

4) Each battery has an independent constant current and constant voltage source, which forms a loop and does not affect each other.

5) Detect the voltage of each battery in real time. When charging, charge with constant current first. When the battery voltage reaches the set value, it will be smoothly transferred to constant voltage charging. When the set time or current termination conditions are met, the charging ends. During constant current discharge, when the battery voltage is lower than the set value, the discharge ends and the corresponding battery indicator light is on.

6) With power down protection function, the original workflow can continue to run after an incoming call.

7) The power tube adopts 50n06, which is suitable for batteries requiring low discharge voltage, such as lithium iron phosphate battery.

8) The upper computer can set 32 step parameters and 256 cycles, and each upper computer can be connected with 1 ~ 10 sets of single chip microcomputer systems (Less than 10 sets are recommended).

9) Supporting software functions.

① The graphic operation interface is adopted to display the data such as voltage, current, time and capacity of each battery, and the corresponding working state and abnormal conditions are displayed in various colors;

② Battery capacity indication of any section (Up to 100 sections);

③ Data points can be recorded according to the change conditions of voltage, current and time to form complete charging and discharging curve data. The time interval of curve data points is ≤ 4 seconds;

④ Battery sorting function under various conditions (Capacity, time, open circuit voltage, discharge platform, etc.);

⑤ Automatically calculate constant current charging ratio, capacity loss, discharge efficiency, average voltage, median voltage and other data;

⑥ Operator authority setting and hierarchical operation;

⑦ It can display charge discharge curve and cycle diagram.

4. Main Configuration Requirements Of The System (Self Configured By The Customer)

1) Minimum configuration of computer system: Celeron dual core CPU or above, 4G or above memory, 500GB or above hard disk space, EGA / VGA color display, one CD-ROM, one mouse, above Microsoft^TM Windows XP operating system, and one available RS232 serial communication port. The computer system shall be configured by the user, and the number of computer systems shall be determined according to the actual needs.

2) The user is recommended to equip each computer with UPS power supply to prevent damage to the computer or data in case of power failure.

3) When the equipment is started, the instantaneous current is large. When the user configures the incoming power switch for the equipment, it should be considered that the action current of the power switch is not lower than the starting current of the equipment to avoid switch tripping.
