TAILIEUCHUNG - Chapter 7: Batteries for Stationary Power Supply

Today the most important electrochemical storage systems for stationary applications are the lead-acid and the nickel/cadmium systems. Both of them have advantages and disadvantages which carefully have to be considered for best selection. Batteries for telecom applications are specially designed for long service life and hours of discharging time. Batteries for UPS applications are designed for discharges with high current over short times (minutes). Special battery constructions are offered for the different requirements. . | 7 Batteries for Stationary Power Supply H. FRANKE INTRODUCTION Today the most important electrochemical storage systems for stationary applications are the lead-acid and the nickel cadmium systems. Both of them have advantages and disadvantages which carefully have to be considered for best selection. Batteries for telecom applications are specially designed for long service life and hours of discharging time. Batteries for UPS applications are designed for discharges with high current over short times minutes . Special battery constructions are offered for the different requirements. In case of high safety demands stationary batteries that ensure long service life are preferred. Already today valve-regulated lead-acid batteries are in widespread use in many applications and this trend will increase in the future since the reduction of maintenance is a significant advantage. This battery system requires high quality of all parameters that influence the performance and other characteristics. Valve-regulated lead-acid batteries that are installed in cabinets require sufficient air circulation to achieve equal temperature for all cells or monoblocs. Monitoring or control systems may be used. For selection of the correct size of a stationary battery manufacturers issue data curves and tables with the performance dates and installation rules to their customers. Most tables are calculated by special computer programs and they include applications with varying current profiles during discharge. Copyright 2003 by Expert Verlag. All Rights Reserved. Monitoring of stationary batteries is especially important to ensure a safe energy supply and the desired service life of the battery For vented batteries there are many proven service methods. For valve-regulated batteries new methods of measurements and monitoring are necessary. Quite a number of automatic monitoring systems have been developed in the past their reliability must be proved in the future. STATIONARY .
