Interpretation of the importance of ETC lithium battery UPS

The toll station power supply and distribution system is the power supply guarantee for the toll operation of the expressway, and its importance is self-evident. Currently, lithium batteries are widely used in various fields, such as backup power supplies. At present, the high-speed charging system is relatively developed. From May 1 next year, ETC's dedicated lanes will be replaced, leaving only one artificial lane for each toll station. At present, expressways are usually built far away from urban areas, and toll stations and tunnels are powered by nearby power sources, using nearby agricultural or household electricity. In order to ensure that the important equipment of the highway management system can work normally after the external power supply is interrupted, the highway power supply and distribution system adopts UPS backup power. The lithium battery UPS is important to supply uninterrupted power to the charging system to ensure the normal operation of the equipment in each channel. In order to ensure the reliability and quality of power consumption, toll stations use lithium battery UPS. When the main power supply fails, the UPS backup power supply is automatically transferred to the emergency generator power supply system to ensure uninterrupted main load power supply. The importance of installing lithium battery UPS power supply in charging systems The ETC number plate recognition system has the functions of license plate recognition and section billing of passing vehicles, and is a key node in deepening the cancellation of inter-provincial expressway toll stations. According to statistics, after the cancellation of the provincial toll station, the average time for passenger cars to pass through the provincial border was shortened from 15 seconds to 2 seconds, and the average time for trucks to pass through the provincial border was shortened from 29 seconds to 3 seconds. The indoor power supply and distribution system of toll station is mainly embodied in the power supply of uninterruptible power supply UPS, communication system and monitoring system. As the name suggests, lithium battery UPS is to ensure the safety of charging monitoring power and uninterrupted power supply. UPS power supply is important to supply uninterrupted power supply for the electromechanical equipment of the toll crossing to ensure the normal operation of the electromechanical equipment of each lane. In order to ensure the reliability and quality of power, the toll station adopts a lithium battery UPS system. UPS uninterruptible power supply system is a set of DC rectifier/charging device composed of AC power supply and a set of AC PWM inverter composed of DC power supply as the manufacturer of lithium battery UPS power supply. We have developed a system suitable for ETC door frame system The uninterrupted lithium battery UPS power supply adopts DSP control technology, with short-circuit protection, frequency conversion setting, output overload, battery charging management, monitoring and other functions. The lithium battery UPS adopts a 19-inch rack structure, which is easy to install and save space. With AC auto-start and lithium battery pre-charging functions, the expansion of three functions can be realized at the same time. It has high stability, high reliability and high practicability, and provides protection for the safe operation of equipment. All primary load facilities, including toll station operating station computer system, toll audit system, toll station charging equipment, monitoring equipment and communication equipment, are powered by UPS. Due to the high reliability of the lithium battery of the UPS, and the previous UPS will be connected to the voltage stabilizer, this design is based on the principle of economy and no longer considers the use of two UPSs, one main and one backup. When the power supply fails, the UPS power supply will automatically transfer to the emergency generator power supply system to ensure uninterrupted primary load power supply. Conclusion: The use of lithium battery-powered UPS to ensure the normal operation of ETC toll stations is an important part of ensuring smooth roads.
