As the battery is truly tested only during an outage, it is important to monitor battery health regularly as part of preventive maintenance so they can be relied upon when the AC power source fails. Capacity testing or discharge testing is an effective way to track battery health and thus ensure reliability.
Battery discharge testing, also known as battery load testing, is a process that test battery health statement by constant current discharging of the set value by continuously the discharge current from a fully charged state and then measuring how long the battery lasts.
Notable discharge testing methods include load bank testing, capacity testing, partial discharge, and charge/discharge cycle testing. The first one is load bank testing. It is the most comprehensive test by which someone can evaluate battery truly. It verifies that the battery can supply its specified power when it is required.
There are several methods: constant current discharge, constant power discharge, constant resistance discharge that can be used to perform a capacity test, but the most common method involves discharging the battery at a constant current until the voltage drops to a predetermined level.
Capacity testing is an effective way to measure battery health. Batteries serve as the main source of power in a substation in the event of an AC outage. They power critical loads and equipment like relays, indicator lamps, circuit-breaker controls, motor operators, SCADA equipment, event recorders, etc.
Stress Testing: Understand how stress testing at different discharge rates helps identify the limits of a battery’s power delivery, providing insights into performance under challenging conditions.
