DEVICE FOR CONTROL OF ELECTROLYTE LEVEL AND STATE OF ACCUMULATOR CHARGE Russian patent published in 2008 - IPC H01M10/48 G01R31/36 

FIELD: electrical engineering.

SUBSTANCE: according to invention as electrolyte level detector stainless steel metal plate is used, which is installed into accumulator tank cover, which is electrically connected to light diode that is also fixed on accumulator cover, which in its turn through resistor is connected to positive lead (terminal) of accumulator. At that rated working voltage of light diode makes 60-70% from nominal accumulator voltage, and value of resistor resistance is defined as quotient from division of difference of rated voltage of accumulator and nominal voltage of light diode by value of maximum durable current of light diode.

EFFECT: provision of permanent control.
