28、 for UPS, etc. applications. These systems are to be installed in accordance with the National Electric Code, ANSI/NFPA 70 or other applicable installation codes. 1.2 These requirements also cover electric energy storage systems (EESS) as dened by this standard for use in light electric rail (LER) a

29、pplications and stationary rail applications such as rail substations. These systems are intended for installation within either the rail car or within a sheltered stationary location such as a rail substation. These electric energy storage systems may utilize regenerative braking from the trains as

30、 a source of energy for recharging and are intended for direct or indirect connection to the rail power lines. These electric energy storage systems are intended for balancing loads during peak hours, serving as an energy storage device during regenerative breaking of the trains, and as a source of

31、emergency power to move trains to the nearest station during power outages. 1.3 Appendix B of this standard includes requirements specic to sodium-beta type technologies. Appendix C of this standard includes requirements specic to owing electrolyte technologies. 1.4 This standard evaluates the elect

32、ric energy storage systems ability to safely withstand simulated abuse conditions. This standard evaluates the system based upon the manufacturers specied charge and discharge parameters. 1.5 This standard does not evaluate the performance (i.e. capacity measurements under various discharge conditio

33、ns) or reliability (i.e. capacity measurements under various environmental conditions) of these devices. 1.6 Figure 1.1 is a boundary diagram example for an electric energy storage system for this application.

44、.6 CELL The basic functional electrochemical unit containing an assembly of electrodes, electrolyte, separators, container, and terminals. It is a source of electrical energy by direct conversion of chemical energy. 4.7 CELL BLOCK One or more cells connected in parallel. 4.8 CHARGING The application

45、 of electric current to battery or capacitor terminals, which results in a Faradic reaction that takes place within the battery that leads to stored electro-chemical energy or in the case of the capacitor, due to electrical charge being stored without a chemical reaction taking place. 4.9 CHARGING,

48、OCHEMICAL CAPACITOR An electric energy storage device where electrical charge is typically stored as a result of non-Faradaic reactions at the electrodes. (A subset of electrochemical capacitors referred to as an asymmetric type have non-Faradaic reactions at one electrode and Faradaic reactions at

49、the other electrode.) A highly-porous surface of the electrodes increases the surface area for holding charge resulting in much larger capacitance and energy density. Electrochemical capacitors differ from common electrolytic capacitors in that they employ a liquid rather than a solid dielectric with charge occurring at the liquid-solid interface of the electrodes when a potential is applied. Some other common names for an electrochemical capacitor are double layer capacitor , u
