Embodiment Construction

[0032] Such as figure 1 Shown is the principle frame diagram of the photovoltaic energy storage system of the present invention. It can be seen from the figure that the photovoltaic energy storage system can store energy in the lithium-ion battery energy storage device in two ways: 1. Using photovoltaic panels to convert solar energy into Electric energy is then stored in the lithium-ion battery device through the photovoltaic charging input port ⑦; 2. Use a 12V charger to store 220V AC power in the lithium-ion battery device through the 12V DC charging input port ⑧.

[0033] The energy stored in the lithium-ion battery device is also output in two ways: a. Provide energy for LED lights through the LED output socket ⑤ for lighting; b. Provide 5V2A output power for electrical appliances through the USB output socket ④, which can Charge or supply power for related devices, such as: mobile phones, MP3, mini fans, etc.

[0034] The power of photovoltaic modules in charging mode 1...

Abstract

The invention relates to a household backup type integrated energy storage system. The system can utilize a solar photovoltaic power generation device and a low-price power source of a social power supply system to store surplus power into a lithium ion battery energy storage device for use in peak hours, can be used as an emergency power supply, and is more suitable for power generation, illumination, electric appliances and the like in areas (islands) without power. Energy stored in the lithium ion battery energy storage device can be discharged through an LED port for illumination, and canalso be used for supplying power to equipment with a USB function through a USB port. The system comprises a 30W solar photovoltaic panel, an AC charger, a 300Wh energy storage lithium battery, a 3W lighting LED, a cable and other complete photovoltaic, energy storage and lighting accessories, is a portable photovoltaic energy storage system capable of independently generating, storing and using power, and has the advantages of long cycle life, small size, visual display, simple and convenient operation, safety and the like.

Description

technical field [0001] The invention relates to an energy storage system, in particular to a portable photovoltaic lithium-ion battery energy storage system. Background technique [0002] With the continuous development of the new energy industry, lead-acid batteries will gradually be replaced by new energy batteries due to their pollution and low energy density. Lithium-ion batteries have gradually been widely used due to their advantages such as high capacity, high voltage, and good safety. Solar energy is considered to be an inexhaustible source of energy, and it has the advantages of cleanliness and environmental protection. Therefore, using solar energy to generate electricity will be a major trend in the future. The existing power supply system is affected by the user's power consumption time period, and there will be peak and valley values, and in some remote mountainous areas, there will often be insufficient power supply. For this reason, it is necessary to store ...
