POWER SUPPLY SYSTEM OF COMBAT VEHICLE Russian patent published in 2021 - IPC H02J1/00 

FIELD: electrical engineering.

SUBSTANCE: area of application: in the field of electrical engineering for power supply of combat vehicles of the weaponry complex under low temperature conditions. According to the invention, components of the power supply system are placed in a body, located whereon are external coupling units of mechanical fastening and electrical connectors to the body of the CV, electrically connected with the control panel and the switching unit. The body is divided by a partition, on one side whereof a fuel system, a static frequency converter electrically connected with the switching and control units, a direct current source electrically connected with the control unit, and a switching unit are placed with a gap from the wall of the body. The static frequency converter, the direct current source and the switching unit are located in the upper part of the body above the fuel system. A diesel engine with a liquid cooling system and a generator are placed on the other side of the partition with a gap from the partition and the body, wherein the generator and the liquid cooling system are located on opposite sides from the diesel engine. A control panel electrically connected with the generator, the frequency converter, the direct current source, the diesel engine, the switching and control units and the cooling liquid temperature sensor is located above the generator and the accumulator batteries. A pre-activation heater electrically connected with the control panel is installed between the diesel engine and the side wall of the body, interacting with the liquid cooling system. An accumulator battery is located in the gap between the generator and the walls of the body in the lower part thereof, and a control unit is located behind the partition.

EFFECT: increase in the reliability and failure-free operation of the system during operation in a wide range of ambient temperatures, as well as a reduction in activation time due to the diesel engine being maintained in a heated pre-activation state.
