Assessment Of Alternatives To Lead-Acid Substation Batteries

systems are typically drawn upon to provide power to circuit switching components and to power substation control equipment in times of AC power loss. In most cases utilities use banks of 100 to 400 AH, heavy-duty, usually flooded- electrolyte lead-acid batteries – though valve-regulated "sealed" designs are also employed – to serve critical dc loads in the 1 to 10 kW range. Nickel

Substation Battery Systems Present & Future

What Information Do We Need to Size the Battery? "Rule of Thumb" – Use 77F or 25C unless the actual ambient temperature the batteries will encounter is LESS than 77F/25C. Use 77F/25C if temperatures will be above. 77F/25C. Design Margin: A factor that adds capacity battery allowing for load additions to the DC system.

Using a Switching Power Supply for Battery Charging

Constant current charging is a way to charge common batteries. This is a charging method where batteries are charged with a constant current from beginning to end. A standard switching power supply is a constant voltage power supply, so it monitors fluctuations in output voltages, inputs the results in the control circuit, and executes constant voltage

Battery Sizing Requirements Under normal operation, the battery charger supplies dc power to recover the battery voltage after a discharge and to maintain the float voltage while supporting any self-discharge losses in the battery system. The charger also supplies the con-

Battery monitoring and maintenance guidelines

The time required to maintain the batteries in a typical small UPS battery cabinet, small telephone office, or power company substation, in accordance with IEEE standards, is at least 25 hours a year. Most of these hours can be saved by using a monitor, and the hours saved will pay for a top of the line battery monitor in two to four years. Optimizing battery life.

How to Perform a Battery Discharge Test Procedure

Are battery discharge tests key for keeping your substation batteries working well? Yes, they are. Testing your batteries regularly is vital. It helps check if they''re ready to power important equipment when needed. The battery discharge test means taking power from the battery in a safe way. We watch it until it hits a certain low voltage.
