1、 Model: tg240 Product Name: (1-24 strings) battery internal resistance differential pressure tester

Function introduction

A multi string power battery internal resistance tester is suitable for rechecking the matched 1-24 strings of batteries. It can test lithium battery, nickel hydrogen battery and so on.

technical parameter

1. Test options and scope

Voltage 0.000v ------ 5.000V precision 1mV

5.00v-100.00v precision 10mV

Internal resistance 0.00 m Ω ----- 50 m Ω precision 0.01 M Ω

0.0m Ω ----- 1000m Ω precision 0.1M Ω

2. Parameter setting

Single cell voltage (upper and lower limits of single cell voltage)

Single internal resistance (upper and lower limits of internal resistance of single battery)

Total voltage (upper and lower limit of total voltage of combined battery)

Total internal resistance (upper and lower limits of total internal resistance of combined battery)

Voltage difference (range of voltage difference between each single battery)

Internal resistance difference (range of internal resistance difference between each single battery)

3. Test process

1. The connection of the probe (the connection part of the probe can be changed according to the output port of the customer's combined battery). The internal resistance test adopts the standard four wire acquisition method to test, ensuring the accuracy of the test.

2. Press the start button to test. The test process starts from the lowest battery (i.e. B-to B1).

4. The display part adopts 5-inch LCD

12   0.000V   0.00 mΩ    24    0.000V   0.00 mΩ

Total voltage: 0.00v total internal resistance: 0.00m Ω

If the test result is not within the scope of the test, it will give a counter display and alarm prompt!

The test speed takes 16 strings as an example: it takes about 5 seconds. Of course, the less strings are tested, the shorter the time

5. Overview of computer software

In the later stage, we can use the joint application scheme of test mainframe box and computer. After the test, all the tested data will be displayed on the computer screen

Computer software is divided into three parts

1. Test data display area 2. Measurement parameter setting area

3. Data saving and parameter saving area

4、 Standard accessories

One tg240 host, one power cord, one fixture box and one manual
