ACCUMULATOR FAILURE DETECTION SYSTEM AND METHOD OF ACCUMULATOR FAILURE DETECTING FOR BATTERY UNIT Russian patent published in 2015 - IPC H02J7/00 

FIELD: electricity.

SUBSTANCE: invention claims system and method of accumulator failure detecting for battery unit used in an electric vehicle. accumulator failure detection system comprises the following: power supply unit; display unit coupled to the power supply unit; battery unit; protection unit coupled to the battery unit and power supply unit; detection unit capable to generate at least one feedback signal when there is failure in accumulator operation; as well as control unit coupled to the detection unit, power supply unit, display unit and protection unit. The control unit may receive the above at least one feedback signal with at least one preset default value and generate signal of failure level. The protection unit controls operation of the accumulator unit according to the signal of failure level while the display unit displays failure message according to the signal of failure level.

EFFECT: detected state of the battery unit and control of the battery unit when there is failure in its operation thus preventing potential injury.
