High Current Battery Emulators

Do you need to emulate high current battery packs for testing xEV components? Perhaps you need simulate ultra-fast dynamics to replicate the real world behaviour of high performance batteries? Our new product family could be exactly what you’re looking for.

G5-BATSIM-HCHigh current G5-BATSIM-HC modules are available from SELV models starting at 60V/338A, ranging up to tens of thousands of amps. This is in addition to existing high voltage battery emulators, which configurations from 500V up to 3000V are possible.

The G5-BATSIM-HC features two current ranges for high accuracy when testing at low voltages. The unit's industry leading response times allow current steps between 90% sourcing to 90% sinking to be performed be as quick as 50us, perfect for supplying high speed drives.

This allows the user to programme a variety of relevant electrical characteristics in a convenient format including number of cells, energy capacity, cut off limits, chemistry type and nominal voltage.

An optional embedded function generator enables V/I and V/W relationships to be programmed against time, to accurately simulate a discharging fuel cell. The function generator can also be used to implement a programmable ripple up to 10kHz, ideal for EIS research.

Modules can be arranged in series, parallel or matrix configurations. Unusually, units can also be connected in master/slave with different nominal values. For example, a 36kW/80V/±1352A module will connect in parallel with a 54kW/80V/±2028A unit to provide 90kW/80V/±3380A. Multi-module systems based around a centre tapped earth are possible, creating a +/- voltage output.

Besides new units, our rental fleet features a number of high current battery emulators up to 72kW/160V/±2704A. High voltage emulators up to 216kW/2000V are also available for hire.
