CCS board

The sub system CCS board defines the settings for the CCS board, which is part of the HIL-connect EV provided by typhoon HIL. The subsystem defines the analog inputs and its conversion of the CP and PP pins. Additionally, the digital outputs for controlling charging are defined.

Dialogue box and parameters

The CCS board subsystem is organized in five tabs defining connection to the HIL Computer.

Tab 1 - General

Pin out settings HIL: defines the analog inputs and digital outputs. It is possible to connect to the top row or bottom row of the HIL computer. But individiual settings are also possible.

Tab 3 - CP/PP

The CP signal is evaluated on the CCS board according to peak voltage, duty cycle and frequency. The PP signal is evaluated according to its resistance. All signals are connected via analog inputs.

Especially for Power HIL solutions, a CP filter can be enabled to improve the signal quality. For peak voltage, a low pass filter showed sufficient results. For duty cycle, the rate limitation showed best results.
