onsemi Energy Storage Solutions

Battery Energy Storage Systems (BESS) are widely used in residential and commercial settings. In homes, BESS provides backup power during outages and lowers costs by shifting energy usage to periods of higher value. In commercial applications, larger BESS units store and manage solar energy, enabling low-carbon emissions. Additionally, BESS helps reduce grid pressure, particularly with the rising demand for EV charging.

Lithium-ion batteries, the major part of the electrochemical storage system, have high power/energy density, high roundtrip efficiency, a compact footprint, and flexibility for expansion. The Li-ion battery is a relatively mature technology that has benefited from more than three decades of commercial development, which makes it a reliable and low-cost solution. The continuous cost down of Li-ion batteries has strongly accelerated the development of energy storage.
