The specification discloses a monitor, a system, and a method for monitoring the electrolyte level in a cell of a multi-cell battery. The system may be powered by leads attached across any one or more cells of the battery. The system includes an electrically conductive probe, having its own wire, that may be installed in any battery cell. The probe is current sampled to provide one or more signals used to determine if the probe is in physical contact with the electrolyte (indicating acceptable electrolyte level). The probe may be sampled as a cathode and as an anode. The probe may be sampled using PWM (pulse width modulation). The probe may be sampled using current limiting.

Battery electrolyte level monitor, system, and method

A liquid level sensor for a liquid electrolyte battery is provided. The liquid level sensor includes a probe having a reference electrode and an electrode array. The electrode array includes a plurality of electrodes that are serially disposed in a lengthwise direction of the probe. The reference electrode is capacitively coupled to each electrode within the electrode array, such that the probe provides a capacitance that varies when the probe is immersed in a liquid level that varies in relation to the probe. The liquid level sensor can alert a user of the need to refill the battery or alert a user of the need to refill the battery in the near future. The liquid level sensor can include a series of LEDs that selectively illuminate to indicate each such condition to the user.

Liquid level sensor for battery monitoring systems

An improved battery monitoring system for liquid electrolyte batteries is provided. The battery monitoring system includes a network of sensors for monitoring the condition or performance of a plurality of liquid electrolyte batteries, for example lead-acid batteries. The sensors are adapted to share data regarding battery condition or battery performance to a standalone device over a wireless local area network. A server in electrical communication with the standalone device receives some or all of the data for analysis, which can result in maintenance alerts and other alerts being sent to the standalone device. The improved battery monitoring system can reduce or eliminate the manual inspection of lead-acid batteries and can improve battery operation and longevity by ensuring an appropriate level of maintenance for each lead-acid battery.
