Powertrain, Motor, VCU & Transmission Working Group Charter
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
Logistics
- 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
Deliverables
- 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
