EVWS Series Battery Simulator

The EVWS series battery simulator has the characteristics of battery simulation, which can simulate battery discharge characteristics and battery charging characteristics. It can be used in different test situations instead of electric vehicle batteries to save space and cost for users. It is continuously adjustable within the full range of voltage 24~800V (1000V), current 0~1000A (peak 1300A)/power 0~500KW (peak 650KW). 

The EVWS series can work in different operating modes such as CV/CC/CP, which can meet the precise testing requirements of different loads. It has a complete self-diagnosis and protection functions, which can prevent instrument damage or personal injury caused by wrong operation or environmental factors. 

It is suitable for the early research and development, type test, reliability test of EV motor and its controller, EV powertrain system and other products, as well as the ex-factory test of products on the production-line. It meets the power supply requirements of GB/ T18488.1-2015, GB/ T18488.2-2015 and GB/ T29307-2012.
