LESSON 1: VEHICLE OVERVIEW
•
The traction inverter module (TIM) (arrow) is located underneath
the center rear of the vehicle.
•
The TIM is a high and low voltage module that performs two
functions:
– vehicle powertrain control
– electric current conversion for the motor/transaxle
•
The TIM controls the vehicle powertrain by processing driver,
module, and sensor inputs, and calculating a motor torque
command.
•
The TIM converts high voltage DC from the traction battery into
three phase AC used by the motor/transaxle.
•
The TIM consists of:
– three high power, high-speed insulated gate bipolar transistor
modules (IGBTs).
– four large filter capacitors (used during precharging functions).
– two-phase current sensors.
– a high-performance microcontroller.
– logic circuitry and control circuits.
