METHOD FOR INCREASING SERVICE LIFE OF CAPACITORS IN SEQUENTIAL UNITS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC H02J7/02 

FIELD: control equipment.

SUBSTANCE: invention relates to device (1) for monitoring and/or balancing ultracapacitor (3) and/or unit (4) containing series-connected ultracapacitors (3). Said technical result is achieved by that an electronic circuit is proposed, which enables implementing charge end protocols with the possibility of controlling voltage at outputs of each ultracapacitor and taking into account parameters of a specific ultracapacitor, but not based on increasing and decreasing the ultracapacitors voltage load by a converter. Proposed device comprises electronic circuit (2) containing digital control means, for example, microcontroller (5), which executes a program of monitoring and balancing ultracapacitor (3) and/or unit (4). Relative capacities of the capacitors are measured and the obtained data is used to determine the moment of time suitable for controlled discharging of certain capacitors. Also used is the data on temperature for determining the moment of time suitable for controlled discharging of certain capacitors.

EFFECT: technical result is longer service life of any separate capacitor to the period, which is not shorter than the service life of the other capacitors in the unit having a longer service life.
