Regenerative High-Power, Electric-Vehicle Simulator and Tester

An outdoor rated device designed to simulate an Electric Vehicle (EV) to test dc fast chargers or ultra-fast chargers. Solution is capable of EV communications using CCS1 or CCS2 EV chargers. The solution can emulate an end-to-end EV charging process up to the rated dc capacity of the EV charger without the use of a battery-based storage system.

Operating modes:

Automatic mode:

This mode may be used for simulating the charging process of a typical EV using different battery curves available in solution’s library. This mode is mainly used for functional and interoperability testing of EV chargers.

Profiling mode:

This mode allows the operator to upload user-defined charging profiles to investigate the impact on fast chargers, as well as the impact of different charging patterns on the host distribution system.

Manual / third-party mode:

In this mode, the user can utilize the third-party interface provided by the solution for testing external EV control units (CU) or cybersecurity testing of DC fast and ultra-fast chargers.
