Summary


EVS Series Battery Simulator is a DC power system that simulates the output state of batteries based on types, and serial/parallel numbers. Widely applied in the R&D process and production testing of OEMs and auto-parts suppliers, it is a highly efficient tool to verify the response characteristics of the test objects under various battery conditions. The Series can simulate charge/discharge characteristics of batteries based on SOC, and types. Typical test objects include motor controller, drive motor, and vehicle assembly etc.
