Component parts

Component parts	Outline
PCM	•  Calculates drive force required by user and controls electric motor output. •  Monitors high voltage battery conditions (voltage, current, charging condition, and temperature). •  Controls DC-DC converter to supply power to vehicle's electrical devices. •  Controls coolant discharge amount of electric water pump. •  Controls cooling fan airflow volume. •  Determines insulation condition of high voltage circuit based on monitoring results of electrical leakage detection device in BECM.
Electric motor	•  Generates drive force using electrical power from high voltage battery during driving. •  Acts as a regenerative brake during deceleration to recover vehicle’s kinetic energy.
Inverter	•  Performs the followings by driving internal power transistors. ―  Converts direct current of high voltage battery to 3-phase alternating current to electric motor. ―  Converts alternating current generated by electric motor to direct current to charge high voltage battery.
Drive motor control module	•  Controls power transistors in inverter based on conditions of inverter and electric motor and electric motor requested torque from PCM. •  Detects conditions of electric motor and inverter, and transmits it to PCM.
DC-DC converter	•  Steps down 355 V DC of high voltage battery to 14 V DC to supply power to accessories and to charge lead-acid battery.
High voltage battery	•  Supplies power to electric motor. •  Stores electrical power regenerated by electric motor.
BECM	•  BECM monitors the following high voltage battery conditions. ―  Electric current ―  Cell voltage ―  High voltage battery module temperature ―  High voltage battery cooling refrigerant pressure ―  Battery refrigerant temperature ―  Quick charge voltage •  Detects insulation condition of high voltage circuit by electrical leakage detection device in BECM and inputs it to PCM.
Battery charge control module	•  During normal charging, converts alternating current supplied from charge port to direct current for charging high voltage battery. •  During charging, communicates with charging system and transmits communication content to PCM via CAN communication.
Charge port-electrical supply unit	•  Drives and performs illumination control of following parts installed to charge port. ―  Charge lid lock actuator ―  Charge connector lock actuator ―  Charge indicator ―  Charge port illumination •  During rapid charging, measures charge port temperature using charge inlet temperature sensor, and transmits it to PCM via CAN communication.
Electronically controlled brake unit	•  During braking, calculates regenerative braking force, and transmits regenerative braking request to PCM and controls hydraulic braking force. •  While TSC or DSC is operating, transmits request signal for braking force control to PCM.
