Daily maintenance for storage battery pack

Check the battery regularly as follows (once every three months):
If the total voltage of the battery pack is different from the specified value, please adjust it.
Cell battery voltage;
Ambient temperature and battery surface temperature;
Tighten the connecting wires of each part of the battery pack, if they are loose, tighten them;
Whether the appearance of the battery is abnormal;
Check whether the connection wire of the battery terminal is clean.
Please replace the battery and contact our company under the following abnormal conditions:
The battery box is broken;
Battery leakage;
The charging voltage of a single battery is abnormal (too high or too low, lower than the average value or 0.15V/cell higher than the average value;
A cell battery is overheated.

Our AG series DC load bank it that machine can help us testing battery health and prolong battery life.

It has two powerful functions:

• On-line monitoring function

When the battery pack is under the state of online discharge, uniform charge or floating charge, it performs real-time online monitoring for all cells. The monitoring items include pack voltage, cell voltage, pack charge/discharge current, pack charge/discharge capacity, pack monitoring time, and etc.

It can also monitor the temperature and to better known the state of each cell. (optional function)

• Discharge function:

The battery pack is removed from system. It performs constant current discharge after setup the parameters. It shows real-time data, such as discharge current, discharge time, discharge capacity, pack voltage, cell voltage, and etc. Discharging can be stopped by the set parameters or artificially.

With reliable and durable feastures:

• Expandability:

The user can setup battery numbers. If it is 48V battery pack, it can on-line monitor or discharge four groups of paralleled battery pack simultaneously.

• Safety and reliability:

User can setup four parameters to stop discharge: pack voltage, cell voltage, discharge time, discharge capacity.

Discharging can also be stopped artificially.

• No need manually correcting voltage.

​

• Real-time data storage:

100 groups of on-line monitoring data and 100 groups of discharge data can be saved. The user can view, delete and export the data.

• It can be controlled and real-time monitored by computer via RS232, meanwhile performs pattern analysis in computer.

​

• Export data via RS232 or U disk.

​

• Undervoltage protection

It cannot be started if the voltage is inconsistent between battery pack/cell and load bank.

• Self-protection

When it is abnormal, it stops testing automatically to protecting batteries.

• 5.7-inch color touch TFT screen with high performance.

​

• Powerful analysis software

The software can generate voltage/current histogram, curve chart and test report automatically (including Excel table and Word document)
