LEAD-ACID BATTERY CHARGING DEVICE Russian patent published in 2024 - IPC H02J7/02 

FIELD: electricity.

SUBSTANCE: invention relates to accumulator equipment and is intended to increase availability of unmanned aerial vehicles, ground and water vehicles. Charging device of lead-acid accumulator comprises DC power supply, rheostat, ammeter, current relay connected in series and connected to terminals of charged lead-acid accumulator, voltmeter, measuring device of electrolyte solution density, thermometer, chronometer. Device additionally contains a hydraulic pump with inlet and outlet hydraulic lines connected to the chronometer; at that, the inlet hydraulic line is introduced into the near-bottom sub-electrode space of the electrolyte solution, and the outlet hydraulic line is introduced into the above-electrode space of the electrolyte solution. Sensors of density of electrolyte solution, temperature, voltage and determination of intense gas release are connected to a comparator of levels of output values, which is connected to a relay-switch of charging current.

EFFECT: reduction of lead-acid storage batteries charging time and volume of labour costs for storage batteries charging.
