STABILISED COMBINED POWER SUPPLY SOURCE Russian patent published in 2013 - IPC H01M10/00 

FIELD: electrical engineering.

SUBSTANCE: power supply source contains terminals for connection to external charger (e.g. solar battery) to which current relay of battery charge, normally open contacts of voltage relay - accumulator (accumulator battery) and ultracondenser (block of ultracondensers) - are connected in parallel through coupling diodes. Power supply source contains also stabilised voltage converters to supply different loads, controlled switches installed at input to these voltage converters. Voltage relay of the accumulator has additional changeover contact which is introduced into power supply circuit of stabilised voltage converters.

EFFECT: high reliability of power supply circuit due to use of ultracondenser, accumulator battery as redundant power supply source, simple manufacturing of control circuit; at that high efficiency of ultracondenser-accumulator is ensured due to more complete use of stored energy in wider range of temperature values.
