Description

Battery-free car emergency starting power supply

【Technical field】

The invention relates to the field of automobile starting power supplies, and in particular to a battery-less automobile emergency starting power supply.

【Background technique】

As we all know, there are many reasons why the car's power supply cannot be started, such as aging of the battery, forgetting to turn off the power and running out of power, low temperature in winter or long-term use of power, etc. The most serious situation of power supply is that the battery The battery is completely out of power, and the on-board circuit system cannot work even when the car key is turned on and off. The best situation is that the voltage and power of the battery are sufficient, but due to aging, low temperature, etc., the internal resistance is large and cannot provide the maximum peak value required to start the car. Power, almost all current cars use maintenance-free lead-acid batteries. If the car battery is out of power and the car cannot be started, a power supply that can emergency start is needed, so a large number of high-rate lithium cobalt oxide batteries appear on the market. Batteries or lithium iron phosphate batteries are emergency starting power sources developed for energy storage. Regardless of which lithium battery is used, due to the shortcomings of lithium batteries being prone to combustion and explosion when overcharged, and the fact that they always contain energy, they are always There is a risk of spontaneous combustion and explosion caused by improper operation and quality defects, bringing potential risks to users.

At present, emergency power supplies also use supercapacitor modules, because the car requires high power density at the moment of starting, but does not require much overall energy. Taking advantage of the low internal resistance and fast charge and discharge characteristics of supercapacitors, It can just achieve the instantaneous high power output required to start the car. However, in actual use, the supercapacitor module cannot be simply connected in parallel to the car battery because the internal resistance of the supercapacitor is extremely low. If it is directly connected in parallel to the car battery , high current sparks will be caused at the moment of connection, which will not only damage the connection clips, but also risk fire, thus seriously restricting the development and application of emergency power supplies in automobiles.

With reference to Figures 2 and 3, when implementing the battery-less car emergency starting power supply of the present invention, the user can adopt two modes, one is defined as the auxiliary starting mode; the other is defined as the independent starting mode. The two modes The difference is that the auxiliary mode does not require power from an external adapter. You only need to clamp the positive and negative clips to the positive and negative output interfaces of the supercapacitor module 3 to start the car, while the independent start mode requires connecting to an external DC. The car can be started only by taking power from the source input port and disconnecting the battery in the car battery pack 3.

When starting the car, the user must first select the starting mode according to the degree of power feeding of the car. For slight power feeding, the auxiliary starting mode can be selected, which is generally suitable for power feeding caused by low temperature or battery aging; and because the car has not been used for a long time or has been forgotten to turn off If the battery is seriously fed by the car circuit, the independent start mode must be used. In this mode, the battery and the car must be disconnected, otherwise the battery will form a serious load; and the digital display tube on display 2 passes through the MCU microcontroller The IC displays the voltage of the supercapacitor module in the battery pack in real time, and the LED indicator light is used to indicate the charging status of the supercapacitor module 3. Red indicates that charging is in progress, green indicates that charging has been completed, and the internal pass-through switch has been turned on. At this time, the positive and negative poles of the supercapacitor module 3 and the battery have been completely connected, and can be used to start the car.

The charging control circuit of supercapacitor module 3 uses TI's bq24640 supercapacitor dedicated charging IC, which can charge from the existing voltage of supercapacitor module 3 to the set maximum voltage. If the input voltage is lower than the set maximum voltage, then Charging stops when the voltage is 1V lower than the input voltage. The charging control circuit of the supercapacitor module 3 will output a charging status signal. This signal is sent to the controller 1. The controller 1 determines whether it has been charged by the MCU microcontroller IC. When charging is stopped or the charging current is very small, it can be approximated as charging is completed. When the completion of charging is detected, the MCU microcontroller IC outputs a signal to drive the LED indicator light. The LED indicator light informs the user that charging has been completed and the car can be started. At the same time, turn off the charging status LED indicator, and at the same time, the MCU microcontroller IC outputs a high-level signal through the DisCharg_EN port to open the load switch circuit composed of 4 N-type field effect transistors and LTC's bootstrap boost IC. This is complete. During the charging process of supercapacitor module 3, the internal pass-through switch has been turned on, and the car is already in a state where the car can be started. If the independent start mode is adopted, after the charging is completed, the external DC source cannot be disconnected until the car is completed. Starting, because the energy stored by the supercapacitor is very limited, if the external DC source is disconnected, the voltage of the supercapacitor will drop rapidly and affect the starting of the car.

Combined with Figure 4-6, since the current equipment often causes leakage due to installation reasons when installing the supercapacitor module 3, resulting in a reduction in the service life of the supercapacitor module 3, therefore, during use The supercapacitor module 3 can be fixed on the stage 108 of the inner shell first, and the supercapacitor module 3 can be fixed through the clamping block 116, and the positive output interface and negative output of the supercapacitor module 3 The interface can be connected to the transmission lines 117 at the two sliding heads 105 through both ends of the connecting pipe 111, and the gravity block 114 in the inner shell base 113 can act like a tumbler, so that the inner shell base 113 can always be used according to gravity. The supercapacitor module 3 is in a horizontal position, and the inner shell can swing back and forth in the outer shell through the sliding head 105, the sliding ball 119 and the connecting tube 111. When the car is tilted on both sides, the inner shell can pass through The sliders 105 on both sides move in the slideways 104 of the outer shell, so that the inner shell maintains a balance within the outer shell. This effectively prevents the supercapacitor module 3 from leaking. When leakage occurs, due to The upper surface of the stage 108 has a concave spherical structure, so the leakage will flow out from the leak hole 112 of the stage 108, and then flow into the liquid storage bin 115 of the inner shell base 113 through the middle hole 120. During maintenance, After taking out the inner shell, open the sealing plug at the sealing port on the inner shell base 113 to dispose of the waste liquid.
