BK-6808PK 20V5A 20V10A EV Lithium Battery Cycle Performance Testing Equipment

BK-6808PK/5/10 Rechargeable battery performance testing equipment

Ⅰ.Main performance of the device

1.Designed and manufactured for performance testing and cycle life testing of rechargeable batteries, especially for R&D. It can detect single cells or battery packs that meet the voltage requirements.

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

3.The equipment has 16 constant current sources. Each constant current source is completely independent and can be controlled independently. Each channel can detect different types and different specifications of batteries. Each charging and discharging process, charging and discharging current and constant voltage value are separated by computer. Programming settings.

4.With a variety of test modes, you can achieve constant power charging, constant power discharge and constant resistance discharge.

5.With AC internal resistance test function, it can detect the internal resistance change of the battery during the charging and discharging process in real time.

6.An optional temperature test module that detects changes in battery temperature during charging and discharging.

7.Optional external voltage test module for users to expand the pressure or thickness of the test battery.

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

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

10.The automatic current feedback adjustment technology is used to overcome the non-linear factors of the current automatic setting, and the current setting accuracy is ensured in the full-scale range.

11.A 16-bit high-precision A/D converter with independent 16-bit D/A circuitry for high current and voltage sampling and regulation.

12.The current is divided into two levels, which can guarantee the current accuracy within the current range.

13.With data power-down protection.

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

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