ANEVS(F) Series Battery Simulator

    ANEVS(F) series battery simulators take bidirectional DC power supply with high precision and high dynamic response as the core, to simulate the external characteristics of battery based on the accurate modeling of various of types of batteries.

Product Introduction

ANEVS(F) series battery simulators take bidirectional DC power supply with high precision and high dynamic response as the core, to simulate the external characteristics of battery based on the accurate modeling of lithium manganese oxide, lithium cobalt oxide, lithium iron phosphate, lead acid, nickel metal hydride batteries. ANEVS series battery simulators are professional equipment specially designed and developed for new energy vehicle power test benches, high control accuracy and fast dynamic response, widely used in testing of motor controllers, motors, and new energy vehicle powertrain. The performance of the ANEVS series battery simulator is better than GB/T 18488 Drive motor system for electric vehicles - Specification and experimental conditions, and GB/T 29307-2012 The reliability test methods of drive motor system for electric vehicles.

ANEVS(F) series battery simulator adopts high-frequency PWM rectification and bidirectional DCDC conversion, FPGA digital control, seamless switching between forward and reverse, automatic bidirectional operation, energy feedback to the grid at full power; advanced digital control, ultra-high control accuracy, fast response, wide output voltage range; compared with conventional bidirectional power supply, it can achieve full range of high-precision output from 0V to full scale, up to 2000V, and the maximum power of a single machine can reach 1MW.

Abundant programming and testing functions, suitable for a variety of applications with different software; to simulate battery output characteristics and battery charge/discharge characteristics; providing 5 common types of battery models. Users can choose the type of battery, the number of battery cells in series, the number of cells in parallel and SOC parameters, so as to simulate the battery output characteristics and charge/discharge characteristics, including change to internal resistance during charging/discharging. In addition, custom battery model output is available.
