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
