ev smart charging twin
Description
The toolbox ev smart charging twin has been developed at the Fraunhofer Institute for Solar Energy Systems ISE, specifically within the Digital Grid Lab in the Smart Grids Department. Its primary purpose is to test the interoperability and functionality of electric vehicle (EV) charging equipment, ensuring robust performance and compliance. The target in the various projects was to develop a digital twin of an EV to emulate the charging behavior of any car - the ev twin. It upgrades typhoon HIL libraries and examples tailored for P-HIL (Power Hardware-in-the-Loop) testing of EV charging infrastructure. These libraries are meticulously designed to facilitate seamless testing processes within the advanced environment of the Digital Grid Lab. Moreover, with the appropriate HIL-Connect solutions from Typhoon, this toolbox can be easily adapted to various testing scenarios beyond the lab. Additionally, the toolbox includes components for controlling power amplifiers from leading manufacturers such as Cinergia and Regatron, further expanding its versatility and application range.
Note: The Toolbox is designed to work with the HIL-Connect EV, enabling seamless integration of EV supply infrastructure with HIL computers. Although the full functionality of the toolbox requires this equipment, many features remain accessible without it or are even available in virtual HIL application.
Main functionality
The toolbox ev smart charging twin is primarily designed to emulate the AC or DC charging behavior of electric vehicles. Core component is the ev twin subsystem, which defines the charging behavior of various EV brands. This comprehensive model includes all essential EV components required for charging, such as the
- CCS Interface,
- Electric Vehicle Communication Controller (EVCC),
- Power Unit with battery,
- Battery Management System (BMS) and
- on-board charger (OBC) either as 3 single phase converter or the bidirectional AC-DC Converter (Generic).
These components are readily accessible through the ev smart charging twin and the library ev twin, allowing for the creation of highly customized and individualized models. In addition to its core functionalities, the toolbox provides predefined P-HIL models compatible with Cinergia and Regatron amplifiers, which are organized in the P-HIL section. Furthermore, it supports Modbus-TCP communication, preconfigured for specific Electric Vehicle Supply Equipment (EVSE) systems, ensuring smooth integration and reliable testing processes. This versatility makes the ev smart charging twin toolbox an essential solution for the development and testing of EV charging infrastructure.
HIL Compatibility
The compatibility with various HIL-Computers and its configuration is mostly defined by the usage of cores for the model. The usage of cores can be minimized by disabling the options
- asymmetric phase loading (Tab: AC)
- activate AC measurement (Tab: HIL Connect)
- activate DC measurement (Tab: HIL Connect)
The following matrix summarizes the needed cores depending on the defined settings:
AC & DC = True | AC & DC = False | |
---|---|---|
asymmetric == True | 5 | 4 |
asymmetric == False | 3 | 2 |
This leads to the suitable HIL configurations shown in the following sections.
