The evolution of home energy storage batteries dates back to the 1970s, when the United States began developing renewable energy technologies and began promoting the use of solar panels in homes. However, because solar energy is not available at night or on cloudy days, an energy storage device is needed to store the electricity obtained during the day. This opens the way for home energy storage batteries.
With the continuous progress of technology, the variety of home energy storage batteries is also increasing. The original home energy storage batteries were lead-acid batteries, but they are gradually being replaced by lithium-ion batteries due to problems such as pollution and short life. Lithium-ion batteries are widely used in home energy storage because of their high energy density, long life and low self-discharge rate.
In the early 21st century, with the promotion of new energy policies, home energy storage batteries have been further developed. Internationally, there are some representative home energy storage battery products, such as TESLA’s Powerwall and LG’s Chem RESU. These products are designed to optimize battery storage capacity, improve safety and improve quality.
With the increasing maturity of energy storage battery technology, its application scope in the field of household energy is also expanding, but also more and more popular. Many countries have introduced policies to support the use of home energy storage batteries to make better use of renewable energy and reduce electricity costs.
In short, the development process of home energy storage batteries carries people’s pursuit of green life and enthusiasm for using renewable energy. It has become an integral part of a sustainable ecosystem and its future in the field of energy is very promising.
