BATTERY OF CHEMICAL CELLS Russian patent published in 2012 - IPC H01M10/44 

FIELD: electricity.

SUBSTANCE: battery of n chemical cells is featured by use of safety fuses as electroconductive components. Each safety fuse has the following peculiarity: in case of short-circuiting of any i-th (i=1,2,3,…n) key element that shunts circuit of series-link i-th safety fuse and i-th chemical cell i-th safety fuse is destroyed by current generated by power of i-th chemical cell. Besides in battery of chemical cells circuit of series-link key element and resistor is connected in parallel to each key element; this circuit is used for voltage grading of chemical cells. All key elements of battery can be based on transistors, in particular, on FET-transistors. Battery of chemical cells contains also battery current sensors and voltage sensors for chemical cells, device controlling key elements that is equipped with in-built programmed microcontroller measuring current of the battery and voltage of chemical cells in compliance with installed program or commands coming from external control device.

EFFECT: reliability enhancement.
