Abstract
Abstract A simulator, in particular for simulating thermal batteries, the simulator delivering an output voltage U bat across output terminals thereof, said output voltage being a function of a current I out delivered, into a load connected to said terminals, and of an e.m.f. parameter. E g and of an internal resistance parameter R g that are determined from simulation profiles that give successive values taken by said parameters under real battery operating conditions during an active life cycle of a given battery. The simulator includes computer equipment delivering the simulation profiles in the form of e.m.f. references C Eg and internal resistance references C Rg to a battery simulation card which, in order to generate the output voltage U bat of the simulator at the output of said voltage programmable power supply feeds said power supply with a battery voltage reference C Ubat determined on the basis of a measurement of the current delivered by said power supply and on the basis of the e.m.f. reference and the internal resistance reference as received from the computer equipment.
