Technical specification for tg5000 charge discharge aging cabinet

Version V1.1

Tg5000 is a charge discharge aging tester with high automation, friendly Chinese interface and high test accuracy. It can accurately test the overcharge protection voltage, charging cut-off current, overcharge protection voltage, discharge capacity and other performance parameters of the battery pack. Customers can judge the charge and discharge performance of the battery according to the charge and discharge curve and test capacity.

1. Hardware architecture

Charge and discharge aging system mainly includes computer server, concentrator and aging instrument, the core of which is aging instrument. The 32-bit ARM chip selected in the main control chip of the aging instrument greatly improves the execution speed compared with the traditional single-chip microcomputer, and can accurately guarantee the strict functional requirements for execution time / sampling time

Performance of aging tester

2.1 charging function

With constant current and voltage charging function

2.2 discharge function

With hate current discharge function

2.3 charging and discharging interface

Fully meet the requirements of battery pack charging and discharging at the same port and charging and discharging separately, that is, 2 wires (P + P -) and 3 wires (P + P-C -)

2.4 equipped with USB interface

It is used for scanning gun to collect ID number of battery pack for data query after battery aging

2.5 safety protection:

Anti reverse connection protection function;

Voltage upper and lower limit setting protection;

Safe discharge current protection;

2.6 split line mode and online mode

In offline mode, the aging instrument is disconnected from the server and works independently. The aging instrument is equipped with a display and keyboard for setting and viewing data

Server control in online mode

2.7 control system

The communication mode of the aging instrument system is the most mature and reliable TCP / IP protocol mode currently used. Based on this communication mode, there is almost no requirement for the number of test channels. It can control thousands of aging instruments to work at the same time, and ensure the real transmission of communication data accurately

2.8 management software

The user-friendly interface and the database management system based on Linux greatly facilitate the staff to query and export data online. The query mode is based on conditions (equipment number / time period / battery number). The export format is excel. Check the aging curve of charge and discharge

Three parameter requirements

3.1 charging requirements:

Charging voltage 0-100V, continuously adjustable, accuracy ± 1mV (special for high accuracy)

Charging current 0-30a, continuously adjustable, accuracy ± 1mA (special for high accuracy)

3.2 discharge requirements:

Discharge voltage 0-100V, continuously adjustable, accuracy ± 1mV (special for high accuracy)

Discharge current 0-60a, adjustable, accuracy ± 1mA (special for high accuracy)

Discharge capacity error 1 ‰ (special for high precision)

Four different points of aging instrument with the same industry

4.1 database management data, greatly facilitate the staff to query data, input query conditions automatically pop-up data, while the traditional is a data for a file way, query is very cumbersome

4.2 the communication mode of TCP / IP network is fast, stable and safe. Unlike the traditional 485 master-slave communication, the data transmission is slow, which limits the number of test channels
