Electricity cost and Thermal system simulation model for EV (proto type)

This is a prototype version of an electric vehicle model for simulating electricity cost and thermal system.

It consists of a motor (power rating: 110 [kW]), a reduction mechanism, a vehicle, a low-voltage battery, and a high-voltage battery as a power train system.
And it consists of a Radiator, a HVAC system, a seat heater, and a PTC heater as a thermal system.

Since it is a prototype version, everything inside the physical model cannot be edited.

* The product version is scheduled to be released on on this website website in July 2022.

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
   Throttle opening, Control brake opening, Control motor current, Control voltage ex. Water pump , Control power ex. Seat heater , Control charge current

・Environmental signals
   Road surface information, Wind speed, Outside temperature, etc.

・Sensor signals
   Vehicle speed, Rotation speed, Torque, Current, Voltage, 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.
