SHIP BALANCER WITH ELECTRIC PROPULSION Russian patent published in 2022 - IPC H01M10/44 H02J7/10 

FIELD: electrical engineering.

SUBSTANCE: balancer for a ship with electric propulsion belongs to the field of electrical engineering and can be used to control the degree of charge and discharge of lithium-ion batteries. Controlling the charge level of the battery will allow the ship's crew to save electricity if the charger is disconnected from the network as soon as each battery cell reaches the required charge. The degree of battery discharge must be controlled so that a vessel with electric propulsion is not left without a course on the transition from one port to another. A relay, an LED, the fifth, sixth, seventh and eighth resistors, the second transistor and the second TL431 microcircuit are introduced into the balancer, and the anode of the LED, the first terminals of the second, fourth, fifth and seventh resistors, as well as the emitter of the second transistor are connected to the positive terminal of the battery. The second output of the fifth resistor is connected to the first output of the sixth resistor, their common point is connected to the first output of the second TL431 chip. The second output of the seventh resistor is connected to the second output of the second TL431 chip. Their common point is connected to the base of the second transistor, the collector of the second transistor is connected to the first output of the relay winding, the anode of the LED is connected to the first output of the eighth resistor. The second terminal of the eighth resistor is connected to the second terminal of the first resistor, their common point is connected to the emitter of the first transistor. The second output of the relay winding, the third output of the second TL431 chip and the second output of the sixth resistor are connected to the negative terminal of the battery.

EFFECT: expanding the functionality of the prototype device by organizing the possibility for the maintenance personnel of a vessel with electric propulsion to control the degree of charge, as well as the discharge of the batteries used to ensure the course of the vessel.
