Abstract

MÉTODO DE AVISO DE ANORMALIDADE DE BATERIA E DISPOSITIVO DE AVISO DE ANORMALIDADE DE BATERIA. O método de aviso de anormalidade de bateria de acordo com a presente invenção envolve detectar uma anormalidade em uma bateria instalada em veículo e avisar um ocupante no veículo, o método de aviso de anormalidade de bateria sendo de tal modo que uma determinação é feita quanto a se uma anormalidade de pressão ocorreu na bateria com base em uma pressão de ar dentro de um conjunto de baterias da bateria, uma determinação é feita quanto a se ocorreu uma anormalidade de tensão na bateria com base em uma tensão de célula da bateria, uma anormalidade é determinada como tendo ocorrido na bateria quando tanto uma anormalidade de pressão na bateria como uma anormalidade de tensão na bateria são determinadas como tendo ocorrido dentro de um período de tempo prescrito, e um aviso é transmitido ao ocupante no veículo quando é determinado que ocorreu uma anormalidade na bateria.
