Overvoltage and undervoltage protection | ✓ | ✓ | ✓ |
Short-circuit and temperature cut-out | ✓ | ✓ | ✓ |
Second level Protection | ✓ | ✓ | ✓ |
The cell voltages, the charging and discharging currents and the cell temperature are monitored by all BMSmart. Dangerous operating states such as overvoltage, undervoltage, short circuit or overtemperature are prevented by disconnecting the electrical connection to the cells. Second level protection (IEC62133) is also installed as standard.
More about the safety features of BMS
All models have gas gauging and balancing functionality. In addition to the state of charge (SoC), a lot of other information such as measured voltages, current and temperature can be read out via the integrated SMBus interface.
Our BMSmart products are assembled to suit the number of cells you require. Typical PCB dimensions are specified in the technical data. Customer-specific adaptations to these external dimensions are usually possible without any problems. We supply fully configured and tested BMS that can be used immediately. We are also happy to develop a BMS that is precisely tailored to your requirements.
We have been developing battery management systems for over 20 years and have incorporated this experience into the development of BMSmart products. The systems are produced on our own production line in Germany.
