Introduction. Electrical energy storage systems (EESS) for electrical installations are becoming more prevalent. EESS provide storage of electrical energy so that it can be used later. The approach is not new: EESS in the form of battery-backed uninterruptible power supplies (UPS) have been used for many years.
3 · Energy storage batteries accounted for 17.6 per cent of CATL''s total battery sales volume, up from 12.5 per cent in 2021. CATL will also supply battery cells and packs to Tesla''s export-oriented Megapack storage plant in Shanghai, which will start production in early 2025 with plans to export, according to a person familiar with the matter.
Think about the example above of the difference between a light bulb and an AC unit. If you have a 5 kW, 10 kWh battery, you can only run your AC unit for two hours (4.8 kW 2 hours = 9.6 kWh). However, that same battery would be able to keep 20 lightbulbs on for two full days (0.012 kW 20 lightbulbs * 42 hours = 10 kWh).
