The primary function of emergency power supplies is to respond to power outages caused by emergencies such as natural disasters or equipment failures. They are typically installed in critical locations such as hospitals, data centers, and transportation facilities to ensure uninterrupted power supply in emergencies.
Energy storage power supplies, on the other hand, offer more diverse functions. Besides serving as emergency power, they can be applied to peak-valley regulation in power systems and as energy storage solutions for renewable energy generation. Furthermore, with the increasing prevalence of electric vehicles, energy storage power supplies are playing an increasingly important role in areas such as on-board charging and mobile energy.
