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. EESS are starting to be used for other purposes.
traction, e.g. in an electric vehicle. For further reading, and a more in-depth insight into the topics covered here, the IET’s Code of Practice for Energy Storage Systems provides a reference to practitioners on the safe, effective and competent application of electrical energy storage systems.

energy storage devices can often supply significant short-circuit currents. Even at extra-low-voltage (ELV) this can present a serious risk of overheating and could lead to burns and/or fire. means of protection against electric shock may be exacerbated when the installation is operating off grid.
With larger capacity energy storage installations, thermal management may prove cost-effective for improving performance and increasing time between maintenance replacements of batteries of certain technologies.
discrete component system: this is an EESS composed of discrete components, for example, charging system and load controller, batteries, and isolation/switching devices. The system may have a.c. and/or d.c. interfaces.
Purely electronic supplies may incorporate various forms of electronic overcurrent and/or overvoltage protection; however, these should be used in conjunction with suitably selected overcurrent protective devices such as fuses or circuit breakers in case electronic protection fails.
