The connection box controller performs the following
functions:
•
monitors voltage levels, currents, temperatures
and other variables.
•
calculates power and derived values.
•
provides all values through its CAN object
dictionary.
•
ensures the correct behaviour of the connection
box in terms of charging and discharging
capacities through a state machine.
•
handles thermal budget, over-voltage, under-
voltage and fault cases.
The connection box controller is equipped with 1 CAN
interface for communication with the system master and
implements the CANopen DS301 standard.
