What is the common standard time period for a station battery to handle an outage of AC power to chargers?

The standard time period for a station battery to handle an outage of AC power to chargers is commonly recognized as 8-12 hours. This duration is typically sufficient to ensure that critical systems and equipment can remain powered during a temporary loss of external AC power, providing a reliable buffer to maintain operations until power is restored or backup systems come online.

This timeframe is based on factors such as the battery's capacity, the load it must support, and the operational requirements of the facility. It allows for both regular operations and the potential need for a controlled shutdown if the outage extends beyond this period. The 8-12 hour range is generally considered the industry standard, balancing the needs for power availability with the practical limitations of battery technology.
