Description

Technical Field

[0001] The utility model relates to the field of emergency starting power supplies, in particular to an automobile emergency starting power supply which uses a super capacitor to provide electrical energy. Background Art

[0002] Supercapacitor batteries, also known as electrical double-layer capacitors, are a new type of energy storage device that has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and green environmental protection. Supercapacitor batteries are widely used and are often used as emergency starting power supplies for cars.

[0003] At present, when the car battery is aging, the battery power is low or the car is in a cold area, the car may not be able to start. In this case, an emergency starting power supply is needed. At present, when using supercapacitor batteries as emergency rescue batteries, the two electrodes of the supercapacitor are directly connected between the two electrodes of the car battery to connect with the car starting electrode (starting coil) to start the car. Figure 1 As shown, two wires are generally led out from the two poles of the emergency power supply, that is, the supercapacitor battery, and a metal clip is welded at the end of each wire, which is clamped on the two poles of the car battery respectively. The two poles of the battery are originally connected to the car starting circuit. When the clips are clamped on the two poles of the battery, the two poles of the supercapacitor battery are also connected to the car starting circuit, and the supercapacitor battery is used to power the car starting circuit.

[0004] However, the existing supercapacitor rescue power supply equipment has the following disadvantages: At present, supercapacitor rescue power supply equipment is widely used due to its advantages of large instantaneous starting current, safe use and no need for charging. However, during the rescue process, the vehicle battery is often seriously low in power, or when only the driver is operating, when the rescue power supply is connected to the battery and then goes to the cab to start the vehicle, the voltage of the rescue power supply is higher than the voltage of the battery, which will immediately charge the battery and cause the voltage of the supercapacitor rescue power supply to drop rapidly, affecting the vehicle starting effect and even causing the rescue to fail. At this time, two people are generally required to reduce the discharge time before starting the vehicle, which is inconvenient to use. Utility Model Content

[0022] In this embodiment 1, Figure 2 As shown, this embodiment is an emergency starting power supply used for emergency rescue of a car after the battery of the car loses power. When the car is emergency started, the anode of the supercapacitor module (supercapacitor battery) of the emergency starting power supply is connected to the anode of the car battery on the car to be rescued by using a wire, and the anode of the supercapacitor battery is connected to the cathode of the car battery by using a wire. In practice, the two poles of the car battery are connected to the input electrodes of the car starting module. Therefore, the two poles of the supercapacitor battery are connected to the power input of the car starting circuit. The supercapacitor battery supplies power to the starting circuit to start the car. After the car is started, the two wires on the car battery are removed, and the car engine drives the transmission mechanism of the car while driving the generator to generate electricity to charge the car battery.

[0023] Because the positive and negative poles of the emergency rescue supercapacitor battery are connected to the positive and negative poles of the car battery, they will directly charge the voltage. When a person operates it, he connects the wires between the supercapacitor battery and the car battery, enters the car's cab, and starts the car. The supercapacitor battery may charge the car battery and use all the capacity of the supercapacitor battery to charge the car battery. There is not enough power capacity for the starting circuit to start the car, causing the emergency rescue to fail.

[0024] In this embodiment, Figure 2 As shown, a switch is set on the wire connecting the cathode of the supercapacitor battery and the cathode of the car battery. The control device is used to close the switch when sitting in the car cab and doing emergency start of the car. At this time, the supercapacitor battery is connected to the car starting circuit to realize the supercapacitor battery to power the car start.

[0025] Specific circuits such as Figure 2 As shown: the switch here is a MOS tube Q, and the D and S poles of the MOS tube Q are connected to the negative pole of the car battery and the negative pole of the supercapacitor module respectively; the switch control circuit generates a control signal connected to the G pole of the MOS tube. The switch control circuit includes a resistor R1, which is arranged between the SG poles of the MOS tube, and also includes a long wire connected between the G pole of the MOS tube and the anode of the supercapacitor module, and a button switch K is arranged on the long wire, and the button switch K is taken to the car cab. A long wire is taken to the cab, and a button switch K is arranged on the wire. When the car key is rotated to start the car, the button switch K is pressed to connect the supercapacitor battery and the car starting circuit, so that the supercapacitor battery can supply power for the car start. When the button switch is not pressed, the two poles of the supercapacitor battery and the two poles of the car battery are not conductive because the MOS tube is not turned on. Therefore, the supercapacitor battery cannot charge the car battery, and the electric energy in the supercapacitor battery will not be lost, and all of it is used to start the car. In practice, it also includes a resistor R2, which is arranged on the long wire; it also includes a diode D, which is arranged on the long wire; and it also includes a voltmeter for measuring the voltage between the two poles of the car level. In fact, it is to check the remaining capacity of the car battery after it loses power. When it is determined that the car breaks down and needs emergency starting because the battery has lost power, the supercapacitor battery can be used to start the car and achieve emergency starting.

[0026] Example 2 Figure 3As shown, this embodiment is the same as embodiment 1, and a switch is also set on the wire between the cathode of the supercapacitor battery and the cathode of the car battery. The switch used here is a relay, and the two ends of the relay are respectively connected to the negative electrode of the supercapacitor module and the negative electrode of the car battery. In addition, the control circuit of the relay also adopts a remote control method, one end of the winding of the relay is short-circuited with the anode of the supercapacitor module, and also includes a transistor Q2 and a remote control device. The other end of the winding is connected to the collector of the transistor Q2, and the emitter of the transistor Q2 is short-circuited with the cathode of the supercapacitor module. After receiving the remote control signal, the remote control device generates an effective signal connected to the base of the transistor Q2. When a person performs emergency start, he presses the car start button in the cab while sending a signal to the remote control device through the remote controller. After receiving the signal, the remote control device generates an effective signal to turn on the transistor Q2, so that the relay winding is turned on, the relay is closed, and the two ends of the supercapacitor battery are connected to the car start circuit to supply power to the car start circuit, and the car is started. In practice, the switch control circuit in this embodiment can also be the same as in Example 1, using a long wire to get into the car cab, and using a button switch to control the relay winding and the two poles of the supercapacitor battery to connect with current, so that the two ends of the relay are closed. Of course, the switch control circuit in Example 1 can also adopt a remote control, and there can be other ways. At present, there are many such ways, as long as remote control is achieved.

[0027] Embodiment 3, as Figure 4 As shown, the difference between this embodiment and embodiment 1 and embodiment 2 is that the switch is set on the wire between the anode of the super capacitor module and the anode of the car battery. The switch is also a relay K3, the two ends of the relay K3 are respectively connected to the anode of the super capacitor module and the anode of the car battery, one end of the winding of the relay K3 is short-circuited with the anode of the super capacitor module, and also includes a transistor Q3 and a remote control device, the other end of the winding of the relay K3 is connected to the collector of the transistor Q3, the emitter of the transistor Q3 is short-circuited with the cathode of the super capacitor module, and the remote control device generates an effective signal after receiving the remote control signal and connects to the base of the transistor Q3.
