TEST BENCH OF ELECTRIC ENERGY SOURCES Russian patent published in 2011 - IPC H02M9/04 G01R31/34 

FIELD: electricity.

SUBSTANCE: device includes load switching unit consisting of connection unit of electric energy sources, inlet three-pole automatic switch, DC power supply unit, the first and the second load switches, each of which includes three-pole automatic switch and m single-pole relays with normally open contacts, n (n=2m) loading circuits including the first group of m loading circuits and the second group of m loading circuits; at that, each of two groups of loading circuits includes up to twelve loading circuits, i.e. m=12. Each of m loading circuits of the first and the second group includes rectifier bridge, thermal resistor, capacitor bank, single-pole relay with normally open contacts, which is intended for remote switching from linear load to non-linear one, and load resistor. Besides, device includes load control panel consisting of start-up switch, test mode setting unit and remote load control unit, and external electric energy source is connected to connection unit of electric energy sources.

EFFECT: test of electric energy sources is conducted in various modes, with linear and non-linear load at simultaneous improvement of the bench operating reliability.
