The charging circuit has an input terminal that may be connected to an external power source, and an output terminal of the charging circuit is electrically connected to the battery pack. Moreover, the battery pack is electrically connected to the MCU micro controller circuit and the DC-DC voltage regulating output circuit, the MCU micro controller circuit is electrically connected to the charging circuit and the DC-DC regulator output circuit and controls the two circuits. The above technical solution has the following advantages: simple circuit schematic, smaller size, light-weight for carrying, easy for controlling, intelligence, low power consumption and versatility, rechargeability using municipal electricity, capability of charging a variety of electronic products with different output conversion terminals or being charged by these electronic products, convenience for managing, carrying and use. The prior patent application solves the problem of outputting power under various voltage levels and having a recharging function, but it can not be used as the vehicle starter because it does not have the high-current outputting capability. In addition, the output current according to the above patent application document is direct current. But in practice, many external equipments need alternating current input, thus the prior patent application failed to solve the problem of powering such equipments in emergency.

With reference to the accompanying drawings and specific embodiments, the present invention will be further described.

As shown in FIGS. 1 to 3 , an emergency power source includes a housing 50 having at its inside a battery pack 4 for storing electric energy.

Furthermore, the battery pack 4 consists of lithium-ion batteries connected in series or parallel, each having a positive electrode made of lithium iron phosphate, lithium cobalt oxide, nickel cobalt manganese ternary lithium or lithium manganate and a negative electrode made of artificial or natural graphite. The output terminals of the battery pack are further connected to a multipath DC-DC voltage regulator circuit and a LED driving circuit 12, each path of the DC-DC voltage regulator circuit is connected to a MCU controller circuit 14, and the MCU controller circuit 14 is further connected to a smart LED electric quantity display system 8 for displaying the electric quantity of the emergency power source, an output terminal of the LED driving circuit 12 is connected to a LED lighting lamp 13, and an equalization protection circuit 3 is connected in parallel with the battery pack 4 for protecting the battery pack 4. The DC-DC voltage regulator circuit includes a DC-DC 19V boost circuit 11 of an output voltage of 19V, a DC-DC 12V output circuit 10 of an output voltage of 12V, and a DC-DC 5V buck circuit 9 of an output voltage of 5V. In addition, the housing 50 of the emergency power source of the invention is made of plastic material, aluminum material or composite material. The solar panel input circuit 2 is disposed outside of the housing 50, and has a power ranging from 0.5 W to 50 W and an input voltage ranging from 5V to 25V.

The emergency power source uses lithium-ion batteries as its battery pack, which has the characteristics of light weight, small size, durability, high instantaneous discharge current and rechargeability, which is capable of supplying a high current for starting a vehicle. By connecting the external smart battery detection system between the high current outputting circuit and the battery pack, the high current can be efficiently, accurately and reliably controlled, and the electric energy can be used more efficiently. The battery pack of the emergency power source is also connected to the voltage regulator circuit for outputting a variety of voltage levels, and by connecting the output terminal of the respective path of the voltage regulator circuit to the MCU controller circuit, various outdoor power demands of mobile phones, computers, digital cameras, car playing pumps, car refrigerators, car cleaners, etc. can be satisfied. The LED lighting lamp may provide outdoor lighting. Moreover, by a smart LED electric quantity display system 8, the power usage status of the battery pack 4 in the emergency power source can be detected in real time.

An output terminal of the DC-DC 12V output circuit 10 is connected to an alerting system 15 for transmitting an alerting signal, an inverter circuit 17 for converting electric energy outputted by the battery pack 4 from direct current form to alternating current form, and a smart heating system 16 for heating the battery pack 4. A start button of the alerting system 15 can be pressed by the user when he or she is lost or some condition occurs. The alerting system 15 may notice people around for help by lighting the indicator light or transmitting sounds with the alerting system 15. The voltage of the alternating current power outputted by the inverter circuit 17 ranges from 110V to 220V, which makes the emergency power source easy to be connected to external devices requiring alternating current power, and the voltage matches with the demand and no regulation is needed. Thus, the external devices may be powered outdoors under power shortage situation, to ensure the normal working of such devices. The inverter circuit 17 may be disposed inside the housing 50, or a connector for connecting the inverter circuit 17 may be provided on the housing 50. When there is a need for alternating current power supplying, the external inverter can be directly connected to the connector to satisfy the demand for converting direct current form into alternating current form, and the operation is convenient. In addition, as illustrated in FIGS. 4A and 4B, the smart heating system 16 includes a heating wire 40A or a heating sheet 40B wrapped around the outside of the battery pack 4, a thermistor 45 attached onto an outer surface of the battery pack 4 and connected to the heating wire 40A or the heating sheet 40B, and a heating starting switch 48 for starting the smart heating system 16. The heating wire 40A or the heating sheet 40B has a resistance ranging from 0.1Ω to 10Ω. When being used, an upper limit temperature t of a surface temperature of the battery pack 4 is preset to range from 0° C. to 70° C. If the external environment temperature is low and affects the normal working of the power source, then the heating starting switch 48 is switched on. If the surface temperature of the battery pack 4 fed back by the thermistor 45 to the MCU controller circuit 14 is lower than t, then the heating starting switch 48 controlling the heating of the heating wire 40A or the heating sheet 40B is switched on so that a heating current flows through the heating wire 40A or the heating sheet 40B, the smart heating system 16 begins to heat the battery pack 4. Before heating, a heating time is preset as a fixed value d ranging from 10 s to 300 s. During the heating process, when the surface temperature of the battery pack 4 reaches the upper limit temperature t, the heating starting switch 48 controlling the heating wire 40A or the heating sheet 40B will be automatically switched off, cutting off the current flowing through the heating wire 40A or the heating sheet 40B. Alternatively, when the heating time reaches value d, the heating circuit of the smart heating system 16 will be automatically switched off to stop heating the battery pack. The smart heating system 16 accurately controls the ON state and OFF state of the heating circuit of the smart heating system 16 using the thermal sensitive property of the thermistor 48, thereby improving the heating efficiency and reducing the power consumption of the heating. With the smart heating system 16, the emergency power source may ensure the normal working of the battery pack and supplying external devices under low environmental temperature that may affect normal working of the power sources. Thus, the reliability of the entire system is improved.

The external smart battery detection system 6 includes a red power source clip and a black power source clip for connecting with an external battery, a relay switchable between an ON state and an OFF state according to a detection signal, a voltage identifying system for identifying the voltage of an external lead-acid battery or a lithium-ion starting battery, and a current identifying system for identifying a current flowing through an external starting circuit. The voltage identifying system is connected between two terminals of a coil of the relay, an input terminal of the relay is connected to the current identifying system, an output terminal of the relay is connected to the high current outputting circuit 7, the red and black power source clips are connected to the battery pack through an anti-reverse connector connected to the positive and negative electrodes of the battery pack 4 or conducting wires welded to the positive and negative electrodes of the battery pack 4. If the red and black power source clips are connected to an insertable anti-reverse connector such that the voltage identifying system is connected to the red and black power source clips. The relay of the emergency power source of the invention is a 12V or 24V relay with a rating current ranging from 20 A to 300 A and 4 to 6 pins. The external smart battery detection system 6 is disposed outside the emergency power source and connected to the emergency power source through an anti-reverse connector, or is disposed inside the emergency power source with the red and black power source clips disposed outside the emergency power. Preferably, in certain embodiments of the invention, the external battery detection system 6 is disposed inside the emergency power source with the red and black power source clips disposed outside the emergency power source. The red and black power source clips and the battery pack 4 are connected with each other by silicone wire or other wires, to connect with the external devices. Reverse connection or short-circuit condition caused by the contact of the red and black power source clip can be avoided by connecting the red and black power source clips to the external batteries.

When the red and black power source clips are respectively connected to the positive and negative electrodes of the external battery, if the connection is correct, a feedback voltage displayed by the voltage identifying system is positive, otherwise the feedback voltage is negative. The positive feedback voltage ranges from value a of 6 to 24 V to value b of 9 to 30 V, and a is smaller than b. If the connection is reverse, the relay does not work, and the high current outputting circuit 7 may be cut off. If the external smart battery detection system 6 fails, to further ensure the safety of the emergency power source, in the circuit of the emergency power source of the invention, a disposable or recoverable fuse 5 is provided and is connected between the output terminals of the battery pack 4 and the external smart battery detection system 6. The fuse 5 has a rating fusing current ranging from 50 A to 500 A. To ensure the safety of charging or discharging the battery pack 4, an equalization protection circuit 3 is connected in parallel with the battery pack 4, providing over-current, overload, overcharging or over-discharging protection for the battery pack 4.

In this invention, when the feedback voltage ranges from value a to value b and is of a positive value, the coil of the relay receives a voltage signal so that its contact is closed and its output terminal is coupled to the high current outputting circuit 7, and the emergency power source starts to power an external device with a high current. At this time, the current identifying system detects the current flowing through the high current outputting circuit 7. If the current is lower than value c, which ranges from 0.1 A to 10 A, the voltage signal across the coil of the relay disappears, the contact is then open, thus its output terminal is disconnected from the high current outputting circuit 7 to stop powering the external device with the high current. The high current outputting circuit 7 has an output voltage of 12V DC or 24V DC, and an instantaneous current ranging from 100 A to 600 A, which can be used as a starting power source for vehicles in emergency. Powering the external device with the high current can be efficiently, accurately and reliably controlled, and the electric energy can be efficiently used by connecting the external smart battery detection system 6 between the high current outputting circuit 7 and the battery pack 4. The external smart battery detection system 6 can be disposed inside the housing 50 or external to the housing 50.
