Study Notes

Gear Drive Unit Function

Transmits power from the electric motor to the wheels
Provides torque multiplication for acceleration and hill climbing

High-Voltage (HV) Battery Role

Stores energy for the electric motor
Enables driving range and performance
Can be recharged through various charging methods

DC Fast Charging Purpose

Quickly replenishes the HV battery with high power levels
Suitable for long journeys and in situations where quick charging is necessary

Common DC Fast Charging Speeds

Level 3 charging: Can charge up to 80% in 30 minutes
CCS (Combined Charging System): Standard for DC Fast Charging in many parts of the world
CHAdeMO (Charge de Move): Another standard for DC Fast Charging, primarily used in Japan

AC Charging Recommendation

Regular AC charging: Recommended for daily use and overnight charging
Reduced strain on battery: Helps prolong battery life by minimizing stress from frequent high-power charging
