The battery for traffic lights is typically installed within the traffic signal control cabinet, which is commonly located at the intersection where the traffic lights are situated. The control cabinet houses various electrical components necessary for controlling the traffic lights, including the battery.
Within the control cabinet, the battery is usually mounted on a rack or shelf. Its placement within the cabinet is designed to ensure easy access for maintenance and replacement while also providing protection from environmental elements such as weather and vandalism.
The battery serves as a backup power source to ensure that the traffic lights continue to function during power outages or other electrical failures. It provides temporary power to the traffic signal control system, allowing the lights to remain operational until normal power is restored.
In some cases, particularly in areas prone to frequent power outages or where traffic lights are critical for safety and traffic management, additional backup power systems such as uninterruptible power supplies (UPS) may be installed alongside or in conjunction with the battery to provide continuous power redundancy.
