    FIELD OF THE INVENTION The invention relates to automobile electrical equipment, in particular, to traveling vehicles,. we have a main electrical system and an additional electrical system for supplying current to additional equipment. To a greater extent, the proposed invention relates to electrical equipment of this type, comprising a main battery and an electric generator driven by a car engine. A device for supplying electric energy to a car is known, which contains a traction motor powered by a main battery and a secondary battery connected to the secondary inductance in the core of an engine 1}. Also known is a power supply unit for automotive electrical equipment with two voltages, comprising a motor and two bridge rectifiers connected respectively to two batteries 2. The closest in essence to this invention is a device for supplying electrical energy to a vehicle with primary and secondary electrical load systems containing the main and additional batteries and an electric generator, kinematically connected with the engine of the car 3. However, in these devices are not provided with an optimal charge of batteries and are not sought to recharge them, which reduces their service life. The aim of the invention is to provide the vehicle with electrical equipment of the specified type, which allows the main and additional batteries to be correctly recharged while the vehicle is moving and in place, while these batteries are not used to start the engine, which increases their service life. This is achieved by the fact that the device for supplying power to vehicles having a main and auxiliary electrical equipment for supplying toksil ancillary equipment, the electrical equipment comprising a main battery, an additional battery and an electric generator, driven by the engine of the c9 derder, also the first on / off switch adapted to connect the generator optionally to the main battery or an additional battery, the power supply unit is connected via the first the second and the second circuit with the main and additional batteries, respectively, the second two-position switch in the first position is connected to the main power source, in which it connects the main electrical system of the car, to the power supply through the third circuit, in the second position it connects the main electrical system a car with a generator, the third two-position switch, which occupies the first position when the car is standing still, while it connects the additional electrical system of the automibil to the unit power through the fourth circuit, in the second position, it connects the additional electrical system of the car with the specified generator, in this case. the power unit is configured to connect the first circuit to the third circuit and the second circuit to the fourth circuit when it is disconnected from the main power source (mains supply).
    In the case of this, the second switch is a relay switch having an excitation winding which is connected to the power supply unit in such a way that & l cause the second switch to shift to the first position when the unit is connected to the supply mains.
    The third switch must also contain a relay switch, controlled by the excitation winding, which is connected to the main electrical system in such a way as to affect the third switch shift to the second position when the lubrication pressure: to its car engine oil is below a certain prog value. It is desirable that & the excitation winding of the third switch was connected to the main electrical system via a disconnecting relay switch, an excitation winding, the connection of which is controlled by a moving contact of the pressure switch which is closed when the oil pressure in the engine drops below the limit value to connect the circuit breaker: excitation and on / off switch.
    The drawing shows a functional diagram of the proposed device, where 1 and 2 are the main and additional electrical systems of the autojobil.
    & vtomo (ML has a main battery 3 and an additional battery 4. The main battery 3 is connected via circuit 5 to the fixed contact 6 of the two-position switch 7, the movable contact of which is connected to an electric generator 8 driven by an engine (not shown) Drughei fixed contact 9 on-off switch 7 is connected via a circuit 10 with an additional battery 4. The dip switch 7, therefore, allows the generator 8 to connect selectively to the main 3 and an additional 4 batteries. Both circuit 5 and circuit 10 contain an ammeter 11 for fixing the current flowing in circuits 5 and 10. The device contains a power supply unit 12, which is intended to be connected to the power source 13 and is connected via circuits 14 and
    15 with chains 10 and 5, respectively. On-Off Relay Switch
    16 is intended to connect selectively the main electrical system 1 of the automobile through a circuit 17-with a block 12 or with a chain 18 connected to an electric generator 8. The relay switch 16 has an excitation winding 19 which, when the block 12 is connected to the mains supply 13, is powered through the circuit 20 from the block 12 so as to cause the relay switch 16 to move to the position in which it connects the main electrical system
    1 with chain 17.
    Another on-off relay switch 21 is adapted to be connected selectively: an additional electrical system 2 of a car with a circuit
    22 extending from chain 18 or with chain
    23 connected to a power supply unit 12. The relay switch 21 has an excitation winding 24, which is connected to the main electrical system 1 through a switch controlled by the vehicle's ignition key, and the contact of the relay switch 25 is open. Relay switch 25 has an excitation winding 26 connected to the main electrical system 1 through the movable contact 27 of the sensor pressure of a known type (not shown) that is sensitive to the oil pressure in the engine of a motor vehicle. When engine oil pressure drops below a certain level, contact
    27 closes to form a circuit for glow plugs 28 on the dashboard of a motor vehicle and connecting a winding 26 for opening the relay switch 25, thereby disconnecting the relay 24.
    When the engine oil pressure exceeds the specified threshold value, the moving contact 27 of the rammykayes turns off the winding 26 and the relay winding 24 is connected, respectively, the junction switch 21 is disconnected
    to the position of connecting the additional electric system 2 with the chain 22.
    The power supply unit 12 has a known construction, so that when it is disconnected from the mains 13, the circuit 14 is connected to the circuit 23 and the circuit 15 is connected to the circuit 17.
    The described device works as follows.
    As soon as the recharging of batteries 3 and 4 is completed, the operation of the device depends on whether the car is moving or standing. If the car is in motion, the generator 8 charges the battery connected to it via switch 7. A known type of control device can be used to control the state of charge of batteries 3 and 4. In the same way, the driver of the car can bring switch 7, to connect a more discharged battery with an electric generator, 8. The second means is preferable for the known method of connecting both batteries to the electric generator 4 8 in parallel - a method which never in practice allows exactly recharging both batteries. A battery that is more charged has a lower internal resistance and, therefore, contrary to the expected effect, it has previously charged a lower potential.
    Switch 7 can be of a known type and controlled in such a way as to connect both batteries 3 and 4 with generator B-for a short interval each time switch 7 changes its position from one to another. This is done to eliminate dangerous voltage and voltage when measuring the connection of the generator 8 to the batteries 3 and 4, when the engine is running.
    Veli Mashna stands still, you can recharge batteries 3 and 4 by connecting power supply 12 to mains 13, then Block 12 will power additional battery 4 through circuit 14, and main battery 3 through circuit 15, independently and simultaneously recharge Ms. both batteries.
    On the other hand, when the machine is in place in case of block 12 being disconnected from network 13 due to de-energizing winding 19, the position of relay switch 16 will be such that the main electrical system 1 is connected to circuit 18, If the ignition key 29 is turned off, then winding 24 it will be de-energized, if the engine of the machine is idling, the oil pressure in the engine will be below the specified threshold value and the pulse will be illuminated. The contact 27 of the pressure sensor will be closed. In this case, the relay winding 26 will be energized, opening the relay switch 25 and de-energizing the winding 24. Thus, the switch .21 in both cases will take a position in which it connects the auxiliary electrical system 2 to the circuit 23.
    When block 12 is disconnected from mains 13, it connects circuit 14 to circuit 23 and circuit 15 .- to circuit 17, Basic electrical system 1 will then be powered from any of the batteries 3 or 4, since it is connected via switch 7 to circuit 18 , and the additional electric system 2 will be powered through circuits 23 and 14 from the additional battery 4. Under such conditions, the main battery 3 will not be able to power the additional electric system 2. This will prevent the main battery 3 from discharging, which will provide the possibility of connecting the starter mash us with the main accumulator. The main battery 3 can be connected to the main electric system 1 of the machine by closing the switch 7 to a fixed contact b.
    The supply of current to electrical systems 1 and 2 depends on whether the machine is moving or standing still. If the machine is standing still, the connection of the power supply unit 12 with the power supply of the network 13 causes the connection of the relay winding 19 through the unit 12, the offset of the relay switch
    16 in position where the main electrical system 1 is connected to circuit 17, circuits 14,23 and 15 are disconnected from each other. The switch 21 remains in the position connecting the additional electrical system 2
    with chain 23,
    Under such conditions, the main electrical system 1 is powered through a circuit.
    17 of a unit 12 connected to the power supply of the network 13, and an additional electrical system 2 is powered through a circuit 23 from the same power supply unit 12. The batteries 3 and 4 are not connected to the electrical systems 1 and 2 of the machine, and unit 12 allows the batteries 3 and 4 to maintain an exact level of charging through the circuits. 14 and 15
