4.4 Generator Mode This mode is:
• The major working mode of BMG. • Generator Power is set in this mode by Scotty AI based on 3 variables: o Engine RPM o Inverter and Motor temperature o Battery SOC% • BMG will stop generating power when and one of these is at it’s limit. • Maximal and minimal rotation speed are also set for generator mode. • BMG will not generate any power when its speed is exceeding speed range.
4.5 Error BMG will activate this state in most failure cases and set motor as freewheeling state. BMG will not react to any system command until failure is healed and or reset. There are different self-healing conditions depending on the failure condition: • New ignition cycle 20
• Error set condition is not active • Fault memory clear is executed
4.6 Warm-up Mode Scotty AI will always control a “warm-up” mode after these conditions are met for more than 30 secs: • BMG speed above 1050rpm 25 • BMG 48V terminal voltage higher than 38V 26 4.7 Power Down • This state is the first-step in the shutdown process of the system. • When 48V system and KL15 are off, the magnetic field of the rotor is de-energized and set motor into freewheeling state. • BMG controller will start post-run. • During this state, BMG can transit back to operation state if engine conditions change.
4.8 Shut Down • BMG will get into shut down state when the post run is finished. • The controller will sleep. • Communication and internal diagnosis will stop.
