The Importance of Household Energy Storage Lithium Batteries

Achieve Energy Self-sufficiency

Household energy storage lithium batteries are often combined with rooftop photovoltaic systems, storing solar-generated electricity during the day for use at night or on cloudy days, thereby reducing reliance on the power grid. For instance, in countries like Germany and Australia, many households achieve an energy self-sufficiency rate of over 80% through the "photovoltaic + energy storage" combination, cutting down electricity expenses.

Optimize Energy Usage Costs

In regions where time-of-use electricity pricing is implemented, households can use energy storage lithium batteries to charge during off-peak hours when electricity prices are low and discharge during peak hours, thus saving electricity costs. With intelligent control systems, they can also prioritize the use of solar power or off-peak electricity, further optimizing energy consumption and reducing costs.

Promote the Development of Green Energy

Take lithium iron phosphate batteries as an example: their cathode material contains no heavy metals such as cobalt or nickel, the carbon emissions during production are reduced by more than 40% compared with ternary materials, and over 95% of materials can be recovered through hydrometallurgy after scrapping. This helps build an environmental protection closed loop, which meets the needs of households for green energy development.

Effective Emergency Power Supply During Outages

Rapid Response to Power Supply

Lithium batteries can charge and discharge quickly, and can switch almost seamlessly when the grid power is cut off, ensuring uninterrupted household electricity supply. For example, the emergency start response time of some household energy storage systems can be controlled within about 10 seconds, which can supply power to household devices in a timely manner.

Ensure the Operation of Critical Equipment

In the face of power outages caused by extreme weather, equipment failures and other issues, household energy storage lithium batteries can serve as emergency power sources to provide continuous power support for critical devices such as refrigerators, lighting, and routers. For households relying on medical equipment like ventilators and oxygen concentrators, energy storage lithium batteries are an important line of defense for life safety.

Provide Power Supply for a Certain Duration

Household energy storage lithium batteries can usually provide power supply for several hours to several days, and the specific duration depends on the battery capacity and household electricity demand. Generally speaking, a 10kWh capacity product can support the continuous operation of a household's core loads for about 7–10 hours, buying users more time to respond to power outages.
