Battery pack into 3 phase Alternating Current.
The 3 phase AC electric motor controls on the
rpm (and the current or battery consumption),
and operate on the frequency without restrictive
torque and machine's performances.
Under the normal conditions (no errors) the
inverter supplies power to the external main
contactor (relay) to close the line. This contactor
is connected in series with the internal contactor
controlled by the BMS, located inside the battery
pack. If the contactor is not closed while the
machine is operating, the movements are not
possible as the electric motor cannot get power
supply.
