Device for charging, discharging and capacity testing of batteries

The device performs computer-controlled charging, discharging and capacity testing of batteries.
The modular structure of the system allows it to be adapted to your requirements.

The device performs 4 main processes:

• charging the batteries (with constant current or constant voltage, depending on the selected charging mode),
• discharging the batteries with constant current,
• capacity test (combination of discharge and charge), after which it prints a capacity test report,
• putting the batteries into operation (combination of discharge and charge).

Charging

The device is divided into separate charging circuits, in which the cells are connected in series.
The maximum values ​​of electrical quantities for 1 charging circuit are:

• Maximum voltage: 80V
• Maximum charging current: 100A
• Maximum charging power: 3kW

Discharging

The device has one discharge circuit in which the cells are connected in series.
The maximum values ​​of electrical quantities for the discharge circuit are:

• Maximum voltage: 120V
• Maximum discharge current: 90A
• Maximum discharge power: 7.3kW

Device functionality

• The device can work with different types of cells, and the settings can be saved in files.
• Only persons with an assigned password have access to the device and its settings.
• Continuous monitoring of the voltage of individual cells.
• Monitoring of the total voltage, current, and power in the charging and discharging circuit.
• Monitoring of the temperature in the main switchboard and in the charging room.
• Monitoring of the active ventilation in the charging room.
• Calibration of the measuring circuit of individual cells.
• Detection and automatic bridging of a missing cell in the circuit.
• Process status notification via SMS messages (process completed, process interrupted, etc.).
• Printing of capacity test protocols.
• Saving capacity test protocols to the database.
• Individual cells can be disconnected and connected during the process.
• Interruption and restart of the process.
• After a power failure, the process can be resumed from the point at which it was interrupted.
