Powertrain, Motor, VCU & Transmission

The mission of Powertrain, Motor, VCU & Transmission Working Group is to

Produce deliverable technical recommendations, specifications, reference designs and sample codes etc. of powertrain, motor, VCU, MCU and transmission for selected EV market segment
Work with cross function responsibilities to develop low GHG products and components through smart control, high power density, new process, new material etc. design
Work with cross function responsibilities to introduce or develop patent of EV powertrain, motor, VCU, MCU and transmission

Scope

The scope of the Powertrain, Motor, VCU & Transmission Working Group is:

EDU with 2 speed or 3 speed gear box
- Two key value for EV Consumers are 0-100 Kmh acceleration and battery range
- EV models in the market at this moment are using one speed EDU, therefore in order to satisfy consumers now a day, you’ll have to increase motor power, which will also increase cost and weight, therefore will also need bigger battery capacity.
  - 1-2% of operation time need Max. power
  - Only need 1/3 of power for max. speed driving ?
  - Advantage to apply multi speed gear box
    - Satisfy 0-100 Kmh acceleration expectation with smaller motor, power supply
    - Reduce weight and cost of motor and MCU
    - Lower energy consumption thus extend vehicle mileage with same battery package
Autonomous Driving & Powertrain & EEA reference design & testing/certification
- Identify EEA reference system and define communication standard
- confirm standard and module design specification
- Develop testing procedure and certification standard

Meetings can be conducted online or presence(e.g. TEAMS)
- Meetings are expected to occur bi-monthly for 1 hour
- Meeting times will be determined based on WG participants time zones

Entire EDU (control + motor + gear box) by vehicle segment
- Assembly interface with vehicle
- I/O with vehicle VCU
- Control I/O with motor and gear box
- Gear box output to wheel end interface
