<p>PURPOSE:To provide a battery deterioration alarm device for a vehicle in which prior to occurrence of system failure, the use is alarmed for deterioration of a battery so that appropriate steps, such as inspection of the battery can be taken. CONSTITUTION:Battery voltage V in a vehicle is detected at least in vehicle starting. When the vale V is out of a predetermined range (between an upper limit value Vmax and a lower limit value Vmin), a step of abnormality is indicated. Thus, a battery deterioration alarm device for a vehicle is constituted, including a main controller 12 for indicating an alarm step when the value is below a set value Vlow in the predetermined range. Accordingly, prior to occurrence of system failure, an appropriate step stop of abnormality, or step of alarm) is taken, depending on state of battery deterioration, so that the occurrence of vehicle uncontrollable state due to system failure is prevented.</p> |
