SmartPro -115

SmartPro is the central component of our BMS. Together with our LiPros (cell voltage measurement, cell temperature measurement and charge equalization) and our PowerPro (fuse, secondary protection and main switch), it forms a highly accurate, powerful and multi-redundant battery management system. SmartPro combines high-precision current measurement to determine the SOC with high-performance, charge and load control. SmartPro is equipped with surge arresters that safely dissipate voltage peaks caused by line inductances. SmartPro can be flange-mounted on the side of the battery pack. The input is located at the top on the edge of the circuit board so that simple installation and wiring is possible.

Main functions:

• Charge and load control depending on the state of charge
• Precise determination of SoH and SoC
• Optional output for heating elements
• Spare part for our complete Supremo battery
• Construction of own battery systems

Application:

• Traffic control technology
• Off-grid monitoring functions (power supply for level measuring stations)
• Emergency power supply for water infrastructure
• Robot vehicles
• Boats
• Power supply for special vehicles
• and much more

Product features and advantages

• High-precision current measurement, temperature coefficient shunt less than 10 ppm
• 24-bit precision ADC
• Current measuring amplifier with < 0.1 μV/°C drift
• Hardware-based short-circuit monitoring and shutdown
• Open data bus: Modbus RTU
• Aux output, e.g. for heating control
• Highly integrated system for monitoring and protecting battery systems
• Versions available for 12, 24 and 48 V battery systems
• Self-consumption can be measured or not measured (for calibration purposes)
• Many other diagnostic data, e.g. SOH, internal resistance, battery efficiency, total charged Ah and Wh, last calibration, etc.
• Meets the requirements of EU Regulation 2023/1542, for which many additional parameters for SoH determination have been introduced.
• Extended SOC calculation methods: In addition to an Ah-based method, it is possible to switch to Wh-based and temperature-compensated methods
