. Main performance of the equipment

1.Designed and manufactured for performance testing and cycle life testing of rechargeable battery packs, especially for R&D. It can detect lithium ion batteriesthat meet the voltage requirements.

2.Designed and manufactured in strict accordance with national testing standards, all electrical performance test items for lithium-ion batteries in the standard can be tested.

3.The device is divided into 1 set of CPU design, and there are 1 constant current source. Each channel independently controls the charging and discharging process, charging and discharging current and constant voltage value are programmed by the computer separately.

4.With a variety of test modes, it can achieve constant current and constant voltage charging, constant power charging, constant power discharging and constant resistance discharging.

5.Modular design and manufacture, long-term operation is reliable and stable, and easy to maintain.

6.The four-wire method is used to measure the wiring and contact error to the maximum extent, and the test accuracy is high.

7.Adopt automatic current feedback adjustment technology to overcome the non-linear factors of automatic current setting and ensure current setting accuracy within the full range.

8.16-bit high-precision A/D converter, each channel has independent 16-bit D/A circuit, high resolution of current and voltage sampling and adjustment.

9.The current and voltage are divided into two levels, which can guarantee the accuracy within the range.

10.With data power-down protection.

11.The host computer can set up to 64 steps and 9999 cycles to display the cycle life curve.

12.Each set of upper computer can be connected to 1-16 sets of single chip microcomputer system.

13.Supporting software features.

A.Realize the functions of centralized measurement and control, data processing and report making of equipment, and have various protection functions such as voltage abnormal protection and current abnormal protection.

B.Provide powerful processing data function, provide a variety of curve modes, such as voltage-time, current-time, internal resistance-time and its superposition curve, eigenvalue, cycle diagram, etc., provide flexible programming selection function, easy to use.

C.Data export function, which can lead the test data to Excel, Word, Access or text files;

.Main technical parameters

.Energy-saving principle block diagram of equipment:

When charging:

Charging adopts switching constant current source, which has higher energy conversion efficiency than traditional linear constant current source;

Energy flow direction: (power grid + energy generated by discharge equipment) → AC/DC two-way inverter power supply → constant current source module → battery

 

When discharging:

Energy flow direction during discharge: battery→constant current source module→AC/DC two-way inverter power supply→battery→(discharging equipment + grid)

When discharging, most of the energy will flow through the factory's AC bus to the charging equipment and other energy-consuming equipment (such as air conditioning, lighting, office equipment, etc.), and there is still excess energy that will be fed back to the grid.
