BaSyTec RPS Battery Pack Test System

RPS Technology

A modern IGBT rectifier/inverter followed by a fast chopper is the basis of the RPS system. This technology allows energy recovery back to the power line whilst discharging, in combination with a fast response time and a low current ripple. The presence of a transformer guarantees the galvanic isolation from the power line. Given that the nominal efficiency of the energy recovery is 95%, the system offers many advantages over other comparable systems. Advantages include:

  • Lower heat dissipation
  • Lower direct energy costs
  • Smaller size
  • Lower indirect costs for air condition

Optimised for electric vehicles, large batteries and high power batteries, the BaSyTec RPS offers up to 600 A and 1000 V.  Parallel operation allows up 1.5MW of power and the energy recovery offers efficiency up to 95% during discharge. The optional CMU Datalogger with up to 4800 inputs for temperatures and voltages makes this system ideal for research battery packs with large number of individual cells.

Key features include:

  • Charge and discharge current of up to 600A
  • Voltage of up to 1000V
  • Continuous power of up to 400kW
  • Current rise time below 5ms
  • Energy recovery while discharging with high efficiency
  • Batteries connected in four wire method
  • Low current ripple of below 0.3%
  • Low line perturbation by use of power factor correction
  • Battery Safety Device for independent battery monitoring and emergency shut-off
  • Interfaces for climate chamber and other third party devices e.g. BMS systems
