Assessment of possible Technologies for Small Scale Emergency Power Supplies

Abstract

Emergency power supplies are mainly used to protect critical infrastructure in case of blackouts. For ordinary population, there are hardly any investigations on usability of different technologies for emergency power supply systems. This paper provides a detailed analysis on which requirements are relevant for laymen usage of emergency power supplies. Furthermore, a method which combines these requirements is used to evaluate a variety of technologies based on the presented criteria and to compare their individual suitability. Advantages and disadvantages of all the examined technologies are provided. With this, a quick evaluation of different technologies with respect to small scale systems is possible. As all requirements are addressed, this helps the reader to get a quite but differentiated overview. Finally, a benchmarking is presented for each criterion and each technology.
