Description

(54) DEVICE FOR LIMITING THE DISCHARGE OF A BATTERY POWER SUPPLY

This invention relates to devices for limiting the discharge of a battery-powered power supply. There are known devices for protecting battery sources of power from a discharge below the permissible rate, which, when placed directly in the source, contain a special push-button or RELAY device to start up. However, such a device makes it difficult to operate the power sources and, moreover, increases the cost of the circuit protection 1. It is also known a device for limiting the discharge of a battery, containing two output terminals for connecting to a load a resistor connected in series with the relay coil, iodine, shunt, closing contact of the relay in the direction of the battery charge, capacitor, resistors and switch 2. However, this device is quite complex, it consumes energy from the battery when the load is disconnected, because between the battery poles, resistor. relay. The operation of the protection circuit depends on the nature of the load, since the base current of the transistor passes through the resistance of the load. In addition, before the final operation of the device, a series of repeated parasitic cycles of operation of the protection circuit occurs due to the discharge of the capacitor, which reduces the service life of the device by at least 2-3 times due to the finite number of operations of the switching contact of the relay. The purpose of the invention is to increase the service life by eliminating parasitic alarms and energy consumption from a battery power source with the load disconnected, increasing the reliability of the battery power source. The goal is achieved by connecting the base of the transistor to the emitter through a series-connected first resistor and relay coil, the connection point of which is connected to the first output contact and to the switch and connected to one of the poles of the battery power supply through it The other pole of the battery power supply and one of the terminals of the relay contact is connected to the base via a capacitor. The other terminal of the junction of the relay is connected to Toryol output contact and through the second resistor with the emitter of the transistor.

The drawing shows an electrical schematic diagram of the proposed device.

The device includes a switch 1 transistor 2, a diode 3, a capacitor 4, a relay 5, a switching contact b relay, resistors 7 and 8.

The device works as follows.

When switch 1 is turned on, transistor 2 opens, since the charging current of capacitor 4 through resistor 7 causes the base current of transistor 2 to appear. As soon as the collector current of transistor 2 reaches the value of relay 5's switching current, relay b of relay 5 closes. As the capacitor 4 is charged, the base current of the transistor 2 decreases, and after the charge of the capacitor 4 has ended, the trans1 stor 2 closes. The switching contact 6 of the relay 5 remains in the closed state due to the fact that the relay coil 5 is connected to the battery power source through a resistor 8.

After a battery power supply is discharged and, accordingly, the voltage on its adhesives is reduced to the minimum allowable level determined by the technical characteristics of the batteries, the current through the resistor 8 and the winding of relay 5 becomes less than the release current, and the switching contact 6 of relay 5 opens, disconnecting the load from the battery power source.

Since when the switch 1 is turned on, the base current of transistor 2, determined by the charging current of capacitor 4 through resistor 7, does not pass through the load due to the fact that the switching contact 6 of relay 5 in the initial state is open, the protection circuit does not depend on the nature of the load .

When the voltage of the battery source is reduced to a level and is romantically tolerated and the switch on the 6th turn of the turner 5 is not felt, the charging circuit of the capacitor 4 does not feel, and the capacitor 4 remains charged, eliminating the possibility of reopening the transistor 2, thereby eliminating the possibility of parasitic repeated cycles of the circuit.

The battery is charged through diode 3,

included in the direction opposite to the direction of the discharge current of the battery source.

The implementation of the proposed battery protection device allows the operation resources to be increased by a factor of 2 to 3 by increasing the service life of the relay, which is achieved by eliminating the parasitic switching of contact contacts, keeping battery power sources with a protection device for a long time, since the protection circuit the idle state is disconnected from one of the poles of the battery power source and, accordingly, does not consume energy from it. In addition, the device expands the range of application of the protection device due to its independence from the nature of the load, reduces the cost

0 protection devices by reducing the number of radio elements included in the protection circuit, and improves the quality of the device operation by unambiguously triggering the protection circuit.
