NAUTY 900
All-in-One Power Module for Electric Mobility and Traction Systems
How does an integrated module with Drive, BMS and AC Charger really work?
The NAUTY 900 is a compact, liquid-cooled module that combines three key systems for advanced electric traction in a single, high-efficiency unit:
- Digital inverter for PMSM motor control
- BMS Master for LiFePO₄ battery management
- Integrated AC charger for direct grid connection
Designed for OEMs and system integrators, it simplifies installation, reduces space and wiring, and accelerates development time.
Key Integrated Functions
Drive
- Controls brushless PMSM motors up to 15 kW
- Torque/speed control, regenerative braking
- Protections: short-circuit, overcurrent
- Custom firmware via browser-based interface
BMS Master
- Supervises 1–16 battery modules (with BMS Slaves)
- Active cell balancing, SOC and SOH monitoring
- CAN or RS-485 communication
- Automatic derating and heating in low temperatures
AC Charger
- Compatible with 230V Schuko or 400V wallbox
- Balances cells while charging
- Integrated with BMS for safe operation
System Architecture
The NAUTY 900 is the intelligent core of a full electric system:
- Collects real-time data from EPM battery modules
- Commands the motor Drive based on energy needs
- Manages and balances charging via the AC Charger
- All communication flows over CANbus
