蓄電池の液面検出装置。The storage battery storage frame and the storage battery terminal are connected through a current limiting resistor and a switching element such as a transistor, and the switching element is opened and closed depending on the presence or absence of a sensor current of a liquid level detection electrode inserted into the electrolyte of the storage battery to be measured. The liquid level detection electrode is connected to the storage battery terminal and to the switching element so that the liquid level detection electrode is connected to the storage battery terminal, and when the sensor current of the liquid level detection electrode disappears, the switching element is frequently opened and closed to close the storage battery storage case. A blinking signal circuit is provided to send a blinking signal to the switching element to vary the earth potential of the storage battery storage case and the vehicle body, and the storage battery storage case and the vehicle body are electrically connected so that fluctuations in the earth potential of the storage battery storage metal box can be detected in the vehicle body. an electric vehicle, characterized in that an indicator circuit is connected between the vehicle body and a plug connected to a storage battery terminal, the display circuit having a configuration that opens and closes a switching element according to fluctuations in the ground potential to blink an indicator light. Liquid level detection device for storage batteries.
