The Battery Simulator is aimed to simulate the behaviour and the power of an adaptable number of rechargeable or non rechargeable batteries, each of them having an adaptable and independent power (up to 150V). It is used during AIT / AIV phases of a spacecraft for representative powering of the spacecraft PCDU.
It can simulate several type of flight batteries like Ni/Cd or Li/Ion batteries, in charge and in discharge situation (discharge / charge current up to 200A).
As a baseline, it provides standard over voltage and over current protection based on COTS items.
As options, it can be fitted with:
> dynamic thermal simulation
> second level over voltage / over current protection per battery (SyCTRL Protection)
> specific sensor simulation (thermistor, cell sample, switch, …)
