The utility model provides an output adjustable energy memory.
At present, a home user prepares an energy storage device to supply power to required electric equipment when the home has a power failure or goes out for camping. However, for the same power supply device, different manufacturers can finely adjust the power supply voltage according to the characteristics of the products of the manufacturers, so that the power supply voltage of the same device is different. With the development of living standard, the electric equipment used by the household users is not limited to domestic production, and the electric equipment in other countries is used, and the electric equipment produced in different countries is designed to adapt to respective direct voltage/alternating current standards. Taking an alternating current standard as an example: the domestic ac standard in japan is 100V, and in the united states 120V; european is 240V: china is 220V. The existing energy storage device outputs discharge voltages with various fixed sizes, so that domestic users in China supply power to electric equipment produced in other countries through the electric energy storage device, and often need a special power supply adapter, which is very inconvenient. And for manufacturers of energy storage devices, different hardware circuits need to be designed according to direct voltage/alternating current standards of different countries, so that the production cost is very high, and the direct voltage/alternating current standard is not favorable for cross-country sales.
In order to solve the above problem, referring to fig. 1 to 3, in an embodiment of the present invention, the energy storage device with adjustable output includes:

In this embodiment, the plurality of discharging interfaces 10 may be one or a combination of three straight holes and three pins female socket 11, three inclined holes and three pins female socket 12, two holes and two pins female socket 13, USB TYPE interface or TYPE interface. Each discharging interface 10 can be connected with an electric device through a power supply line so as to correspondingly output a discharging voltage to supply power to the connected electric device; it can be understood that, the one end that the power supply line is connected with the interface 10 that discharges can be public seat plug, can be equipped with a plurality of conducting strips on the public seat plug, and can be equipped with the metal slot of corresponding quantity in the interface 10 that discharges to when public seat plug inserts the interface that charges, make conducting strip and metal slot inconsistent, in order to realize will discharge voltage and transmit to the consumer of connection through the power supply line.
The electrical energy store 20 may be implemented as a battery pack. The electric energy storage 20 is used for converting the stored chemical energy into discharge voltage output when discharging. It can be understood that the energy storage device of the present invention can further be provided with a charging interface for accessing the charging voltage and outputting the charging voltage to the electric energy storage 20 to charge the electric energy storage. The capacity of the electrical energy storage 20 may range from 660Wh to 850 Wh; the output range of the discharge voltage can be 11V to 17V. Thus, when the plurality of discharging interfaces 10 are connected to the electric devices respectively, a sufficient discharging voltage and a sufficient power supply time are provided for each electric device, and each discharging interface 10 in this embodiment may output a corresponding discharging voltage to the electric device according to a difference in power supply voltage required by the connected electric device.
The multi-path discharging power supply processing circuit 30 may be one or a combination of multiple power supply conversion circuits such as a BOOST voltage boosting circuit, a BUCK voltage reducing circuit, an inverter circuit, and the like. It can be understood that, a person skilled in the art can control the output direct voltage by controlling the duty ratio of the switching devices in the BOOST voltage BOOST circuit and the BUCK voltage reduction circuit, so that the discharge interface 10 connected to the BOOST voltage BOOST circuit can output a direct current discharge voltage with a larger voltage value, and the discharge interface 10 connected to the BUCK voltage reduction circuit can output a direct current discharge voltage with a smaller voltage value. The voltage value of the alternating voltage output by the inverter can be controlled by controlling the turn-on/turn-off sequence of each switching device in the inverter circuit and the turn-on time of each switching device by a person skilled in the art.

Alternatively, the B and C keys are also implemented by using a knob, and a user can directly adjust the voltage value of the selected discharge interface to be 5V, 9V, 12V, 24V, or the like by rotating the knob to a corresponding angle.
The main controller 50 may be implemented by a microprocessor such as an MCU, a DSP or an FPGA, or may be a dedicated control chip. The main controller 50 may determine the triggered function characterized by each key signal by running integrated hardware circuitry and software programs or algorithms and invoking stored parameter data to analyze the various key signals output by the user trigger circuitry 40. For example: when the main controller 50 receives a key signal representing that "the discharge interface 10 requiring adjustment of the discharge voltage is selected", the discharge interface 10 requiring adjustment by the user and the discharge power supply processing circuit 30 connected to the discharge interface 10 can be determined according to the key signal. When the key signals representing 'increase discharge voltage' and 'decrease discharge voltage' are received, the voltage value amplitude needing to be increased or decreased can be determined according to the key signals, and corresponding control signals are output to the discharge power supply processing circuit 30 connected with the discharge interface 10, so that the discharge power supply processing circuit 30 can be controlled to adjust the magnitude of the accessed discharge voltage, and the magnitude of the discharge voltage output after adjustment can be matched with the key signals.
In practical use, the power supply interfaces adapted to the electric devices using the same type of power supply voltage are often the same, for example: the power supply voltage required by the equipment A is 5V direct current voltage, the power supply voltage required by the equipment B is 10V direct current voltage, the two are powered by USB, and if the USB interface of the energy storage device can only output 5V discharge voltage, the energy storage device can not drive the equipment B to normally work. In the embodiment, by combining the multi-path discharge power supply processing circuit with the user trigger circuit, the user can adjust the discharge voltage of the USB interface to 5V through the user trigger circuit when the device a is powered, and can adjust the discharge voltage of the USB interface to 10V when the device B is powered. Therefore, the user can flexibly adjust the discharge voltage output by any discharge interface 10 according to the actual situation of the electric equipment, so that the discharge voltage output by any discharge interface 10 can be matched with the electric equipment connected with the discharge voltage, a special power supply adapter is not required to be prepared, and the convenience in use of the user is improved. And for the electric equipment which needs large voltage for quick charging and then needs small voltage for fine charging, the embodiment can also meet the power supply requirement of the equipment. For manufacturers, the adjustment authority of the discharge voltage is given to users, so that different hardware circuits do not need to be designed for different countries, the production cost is reduced, and the market development of other countries is facilitated.
