BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency power supply for an automobile.

[0002]

2. Description of the Related Art An emergency power supply for an automobile is a battery which is mounted in an automobile and is in a completely discharged state (for example, a lead storage battery) due to forgetting to turn off a headlamp or excessive consumption of electric power by other electric components. If the engine of a car falls into a state where it is difficult to start due to the rise of the battery), the electric power necessary to start the engine of the car is supplied instead of the battery and the cell motor is turned or the battery is charged. This is a power supply device for starting an automobile engine by using electric power stored in a battery to escape from an emergency such as described above.

Conventionally, as such an emergency power supply, a power supply using a charger, a portable power supply or the like has been put to practical use. A charger converts a household AC power supply to DC and charges the battery, and a portable power supply is composed of a lead storage battery or the like, and uses this power in an emergency while keeping it charged. Things. A primary battery using a water-filled air battery has also been put into practical use as an emergency power supply device.

[0004]

The above-mentioned emergency power supply has the following problems as an emergency power supply when the battery mounted on the vehicle goes out of power.

That is, when a charger is used, it cannot be used where there is no AC power supply. In addition, the portable power supply must always be kept in a charged state, and the handling of air batteries is extremely troublesome, such as immersing the batteries in an electrolyte or taking them out, and has not been widely used.

[0006]

Means for Solving the Problems A thermal battery is incorporated in an emergency power supply for automobiles, and a part of the battery which has been rapidly raised by the power of the thermal battery is partially charged, and the partially charged battery is used in combination with the remaining thermal battery capacity. Then, the above problem is solved by supplying electric power for starting the engine of the automobile.

[0007] A thermal battery is a battery using a molten salt as an electrolyte. Since the electrolyte is a non-conductive solid salt stored in an unused state, power cannot be supplied to the outside. By burning the heat generating element, the electrolyte is heated to be in a molten state with good conductivity, so that electric power can be supplied to the outside.

Such a thermal battery has the following advantages: (1) Almost no self-discharge and storage for 10 years or more. (2) A high-current discharge is possible because an active material having high activity such as calcium, magnesium, and lithium can be used. (3) Usable in a wide temperature range of -55 to + 75 ° C. (4) Strong against vibration and impact. It has been practically used as a power supply for flying objects or an emergency power supply.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the emergency power supply device for a vehicle according to the present invention will be described below with reference to the drawings. FIG. 1 is a diagram in which a vehicle emergency power supply device using a thermal battery according to the present invention is connected to a vehicle whose battery is dead. In FIG. 1, reference numeral 1 denotes a battery mounted on a vehicle that has run out of power and cannot be started. Reference numeral 2 denotes an automobile emergency power supply device main body.
Reference numeral 3 denotes a battery having a theoretical capacity of 3700 A · 60 mm in height and 60 mm in height as a power supply incorporated in an emergency power supply device for automobiles.
sec. thermal battery. Reference numeral 4 denotes a starting power supply for supplying a current for igniting a heating element incorporated in the battery in order to start the thermal battery. If a separate starting power source is not provided, the remaining capacity of the raised battery can be used as the starting power source for the thermal battery. Reference numeral 5 denotes a switch attached to the starting power source 4 of the thermal battery. Reference numeral 6 denotes a clip for connecting to a terminal of a battery to be charged.

Referring to FIG. 2, a circuit diagram of the vehicle emergency power supply device of the present invention will be described. The emergency battery power supply 2 for the vehicle is connected to the battery 1 mounted on the vehicle whose battery has risen, and the thermal battery start switch 5 which is in a normally open state is pressed, so that the thermal battery 3 incorporated in the emergency power supply 2 for the vehicle is built in. A starting current flows from the thermal battery starting power supply 4 to the igniter 7, and the igniter 7 ignites to start the thermal battery 3, generate electric power, and charge the vehicle-mounted battery 1.

In fact, when the battery is dead due to forgetting to turn off the headlights or small lamps, or excessive consumption of electric power by other electric components, and the engine cannot be started, the emergency power supply device for automobiles is used. By connecting the clip to the battery terminal and pressing the switch for starting the thermal battery, the thermal battery generates power and starts charging the battery instantly. After charging for 15 to 40 seconds and then turning to the driver's seat and turning on the key switch, the 2,000 cc class engine is rapidly cooled using the partially charged battery and the remaining capacity of the thermal battery together at an ambient temperature of -10 to -10.
It was possible to start at a temperature of + 10 ° C.

[0012]

[Effects of the Invention] The emergency power supply device for automobiles of the present invention can be reliably operated by a simple operation when the battery runs down in a cold place such as a ski resort and under the worst conditions of a place without AC power supply. The engine can start. In addition, the thermal battery in the electromotive section has little self-discharge and uses an active material that can take out a large current, so it can be reduced in size and weight, and it is convenient to carry without taking up space. Can be stored for more than 10 years, -55 to +7
It can be used under a wide ambient temperature of 5 ° C., and is extremely practical.
