Ver. 1.0.0 for R2021a
This is an electric vehicle model for simulating electricity cost and thermal system.

The powertrain of it consists of a motor (power rating: 110[kW]), a reducer mechanism, a vehicle, a low-voltage battery, and a high-voltage battery. And the thermal system of it consists of a radiator, an HVAC system, a seat heater, and a PTC heater.
Input / output signals are connected as follows.
Control signals and environmental signals are connected to the input ports.
Sensor signals and monitor signals are connected to the output ports.
There is no external connection to the physical conserving port.

 

List of signals :

・Control signals
   Control brake opening , Control motor current,
Control voltage [ex. Water pump], Control electric power [ex. Seat heater], Control charge current
 
・Environmental signals
   Road slope, Wind speed, Outside temperature, etc.
 
・Sensor signals
   Vehicle speed, Rotation speed, Torque, Current, Voltage, Electric Power, Temperature
 
* This physical model can be connected to the control model, which is a case study model in “Plant Modeling I/F Guidelines for Vehicle Development” published by the of Japan Automotive Model-Based Engineering center.
