Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electrical equipment, especially to a portable hybrid power storage power supply. BACKGROUND

[0002] Various electrical equipment not only provides convenience for people's life and work, but also improves work efficiency. With the improvement of living quality and the increase of outdoor activities, the outdoor use demand of various electrical equipment is more widespread.

[0003] Portable power supply equipment uses energy conversion and energy storage technology to provide power supply for outdoor emergency power demand, and provides protection for effective outdoor operation and rescue. The existing outdoor power supply equipment mainly includes portable battery energy storage power supply and portable oil / fuel generator. The portable battery energy storage power supply mainly uses rechargeable lithium ion battery technology and power inverter technology to convert charging and discharging energy, and provides energy for outdoor emergency power, construction operation, emergency medical rescue and leisure entertainment. The portable oil / fuel generator uses engine and generator to convert energy and provide power supply for emergency power demand.

[0004] Although the existing portable battery energy storage power supply and portable oil / fuel generator can provide power supply for outdoor power demand, there are still some problems in the use process:

[0005] Firstly, the existing portable battery energy storage power supply is limited in charging when used outdoors. The existing portable energy storage power supply charging method is generally household alternating current charging and solar charging. When charging outdoors, only solar charging can be used. If you want to shorten the charging time, you can only increase the power of the solar panel. However, the solar panel is not only expensive but also bulky, which is very inconvenient to carry.

[0006] Secondly, the existing portable battery energy storage power supply has a short endurance time. After being fully charged, the discharge can only maintain for less than one hour under the rated power condition. To obtain continuous output, the battery pack capacity must be increased. However, increasing the battery pack capacity not only increases the cost but also doubles the weight, occupies space, and is very inconvenient.

[0007] Thirdly, the existing portable energy storage power supply has high working temperature of built-in components. In order to ensure good heat dissipation effect, fan forced air cooling technology is usually used. Since fan cooling requires air convection, the circuit board, battery cell and other heat generating bodies including the inverter module and battery module cannot be sealed in a cavity, or the fan inlet and outlet are opened on the sealed cavity of the heat generating body for heat dissipation. This leads to the fact that the portable energy storage power supply is easily damaged when used in a rainy environment. The immersion of the circuit board and the battery cell not only causes product function failure, but also causes short circuit and fire safety accidents.

[0008] In addition, for portable fuel / oil generator, there are problems of large noise and limited use scene during use.

[0009] Therefore, how to improve the convenience of portable power supply equipment, provide high power long endurance output capability, and provide silent power supply under certain working conditions, especially how to solve the problems of heat dissipation, sealing and waterproof at the same time, has become a series of major challenges in the design and research of energy storage power supply.

The dual power regulation module is used for power superposition of the generator set output AC and the bidirectional inverter module output AC and outputs AC to the power equipment. The household AC is connected to the AC input end of the bidirectional inverter module. The bidirectional inverter module outputs AC and supplies power to the power equipment through the dual power regulation module.

The dual power regulation module can realize power superposition output to the power equipment, and solves the power demand of high-power power equipment in some occasions in the prior art. The existing single power supply mode cannot realize this technical effect.

[0087] As in other embodiments, when used outdoors, start the fuel / oil generator set. The generator set outputs AC power to the power equipment through the dual power regulation module. When the fuel / oil is insufficient or the fuel / oil generator set is not started, the solar panel outputs AC power through the MPPT module, the bidirectional inverter module and the dual power regulation module to provide power to the power equipment.

The specific application mode includes: ① when the household alternating current condition is met and the energy storage battery pack is full of electric quantity, the power supply electric energy is input through the power supply line connected with the alternating current input end of the bidirectional inverter module, and the alternating current output by the bidirectional inverter module is provided to the electric equipment through the dual power control module; ② when the household alternating current condition is met and the energy storage battery pack is short of electric quantity, the power supply electric energy is input through the power supply line connected with the alternating current input end of the bidirectional inverter module, and the alternating current output by the bidirectional inverter module is provided to the electric equipment through the dual power control module and simultaneously charges the energy storage battery pack; ③ when the household alternating current condition is not met, the electric energy is generated through the alternator set and is output as alternating current through the dual power control module to provide power to the electric equipment; ④ when the household alternating current condition is not met, the alternator set is not used, and the energy storage battery pack is full of electric quantity, the solar panel is used through the MPPT module, and the alternating current output by the bidirectional inverter module is provided to the electric equipment; ⑤ when the household alternating current condition is not met, the alternator set is not used, and the energy storage battery pack is short of electric quantity, the solar panel is used through the MPPT module, and the alternating current output by the bidirectional inverter module is provided to the electric equipment through the dual power control module and charges the energy storage battery pack; ⑥ when the household alternating current condition is not met, the alternator set is not used, and there is no solar energy condition, the energy storage battery pack is used, and the alternating current output by the bidirectional inverter module is provided to the electric equipment through the dual power control module. Since the dual power control module is arranged, the alternating current output by the alternator set can realize power superposition output with any form of alternating current output of the household alternating current, the solar panel or the energy storage battery pack.

[0089] It is worth noting that in the utility model, when the energy storage battery pack is charged, automatic charging is preferably adopted. For example, if the input power (household alternating current or generator power or solar panel) is 2000W and the electric equipment is 1000W, then 1000W is used to charge the energy storage battery pack. The bidirectional inverter module is simultaneously provided with an alternating current input end and a direct current input end, and the power supply line is connected with different input ends according to different electric energy forms.
