KR970008711A - Dual-structure battery unit to enable vehicle start even when discharged - Google Patents

Abstract

The present invention is to install a protective circuit between the main battery connection cable between the main battery connection cable and a device to allow the current to flow only in a single direction such as a diode so that the vehicle can be started even if the main battery of the vehicle is discharged, the charge is normally Then, when the main battery is discharged and the driver starts with the key, it automatically supplies the power of the auxiliary battery to the starting motor.

In other words, the main battery is normally used and the spare battery is charged, but when the main battery is discharged and the vehicle does not start, it detects this and automatically supplies the spare battery power to the vehicle to start the vehicle. In the present invention, the present invention can solve the inconvenience of starting up by connecting two batteries with the help of an external vehicle or calling a vehicle inspection service vehicle during the discharge of the main battery.

Through this, the driver's discomfort due to the discharge of the battery of the vehicle and the trouble caused by the discharge after parking in a particularly remote place can be easily solved.The components are inexpensive and can be installed without additional cost. It can be more convenient than carrying batteries and expensive connecting cables in the trunk.

Description

Dual-structure battery unit to enable vehicle start even when discharged

Since this is an open matter, no full text was included.

FIG. 1 is a configuration diagram of a battery device having a dual structure such that a vehicle can be started even during discharge of the present invention. FIG. 2 is a detailed view of a battery device having a double structure so that the vehicle can be started even during discharge of the present invention.

Claims (4)

In the dual battery battery device capable of starting a vehicle even when the main battery is discharged, the negative terminals 17 and 27 between the spare battery 15 and the main battery 24 are connected by a connecting cable 28, and usually The relay 18 and the main battery + terminal are connected to the relay 18 and the main battery + terminal to control the direction of the current flow so that the current flows from the main battery 24 or the generator to the backup battery 15. The main battery 24 and the diode 23 are connected between the terminal 25 of the diode 23 and the + terminal connecting terminal 21 of the spare battery 15 by a relay contact pin 33. ), It operates only as a forward charging circuit connected to the spare battery 15, and reads the main battery 24 voltage when the pulse comes in through the photocoupler 30 and latches the inverter after starting the motor start request signal 31. The voltage value and the pulse and the output to the relay 18 control signal. Therefore, when the main battery is discharged, when the vehicle start signal is received, the relay contact pin 33 connects the diode 23 to the + connection terminal 22 and the main battery + connection terminal 25 of the spare battery 15 automatically. By discharging and connecting the spare battery 15 can be discharged, the vehicle is started using this power source, after starting the generator, the generator returns to charge the main battery 24 and the spare battery 15 automatically relays A battery device having a dual structure so that a vehicle can be started even when discharged, which is characterized by being off and returning to a charging mode. According to claim 1, which is provided in the same case by embedding a diode 23, a relay 18, and a spare battery in the main battery, but for applying to a vehicle in which an existing battery is installed, 18), the diode 23, the end circuit 29, the inverter 32, the photocoupler 30 is attached to the + terminal 16 and-terminal 17 to be connected to the main battery 24 to be used. A spare battery device having a built-in protection circuit for starting a vehicle in the event of discharge of the main battery. The main circuit 24 according to claim 1, wherein the comparator is used instead of the inverter 32 so that the voltage of the main battery 24 is lower than that of the spare battery 15, and the AND circuit 29 is operated when a start request signal is input. When the voltage of the battery is lower than the spare battery, the battery device having a dual structure so that the vehicle can be started even when the main battery voltage is low, characterized in that automatically supply the power of the spare battery (15) at start-up. The main battery 24 according to claim 1, wherein when the starter motor request signal 31 comes in, the relay 31 is turned on through the photocoupler 30 immediately instead of measuring the voltage of the main battery 24. Auto battery supply at start-up, characterized in that the spare battery (15) is used together and the spare battery is usually configured to charge only. ※ Note: The disclosure is based on the initial application.
