Testbench Battery Management System - Flexible test system for battery models
T-BMS (Testbench Battery Management System) is a Battery Management System (BMS) designed especially for use in test bench applications.
Why?
The T-BMS is designed to be used with lithium-ion battery cells. The T-BMS can monitor up to 72 cells. Each CMU connected to the T-BMS can monitor up to 36 cells. The CMU is designed to measure the cell voltage and cell temperature of the connected Li-Ion cells.
The CMU is furthermore designed to balance the Li-Ion cells.
Consists of
- T-BMS Main Unit : Testbench Battery Management Main Unit (“Master”)
- Up to two CMU: Cell Monitoring Units (“Slave”)
- A comprehensive Software (T-BMS Communicator | graphical user interface “GUI”) allows the user to configure the T-BMS for a wide range of applications.
T-BMS Setup:
- T-BMS Main Unit
- Up to two CMU (Cell Monitoring Unit)
- AuSy interface (CAN)
- Parameterization Software (T-BMS Communicator)
- External Contactors
- Current Shunt
T-BMS Hardware Functions:
- Monitoring up to 72 Cell voltages
- Monitoring up to 24 Cell temperatures
