Standby battery power supply system with multi-path outputs for machine room

Abstract

The invention discloses a standby battery power supply system with multi-path outputs for a machine room. The system comprises a single-chip microcomputer, a voltage-dividing module, a change-over switch, a voltage sensor, a power supply module, an electromagnetic circuit breaker B, a surge protector, a charging module, a lithium battery, a voltage adjustment module, a voltage converter, a power supply, and an electromagnetic circuit breaker A. Therefore, charging can be carried out effectively. Since the voltage adjustment module is arranged at the output end of the lithium battery and is able to adjust the voltage and current outputted by the lithium battery, so that the voltage outputted by the lithium battery is kept to be stable and electric equipment in the machine room works stably.Meanwhile, the voltage-dividing module is used for carrying out voltage dividing on the voltages outputted by the lithium battery and the power supply and thus the power supply system provides the working voltage and current directly for various devices of the machine room, so that the standby battery power supply system can output various stable voltages.

Description

technical field [0001] The invention relates to a power supply system, in particular to a computer room standby battery power supply system with multiple outputs. Background technique [0002] As the number of electric vehicles continues to increase, the number of off-line lithium batteries used in electric vehicles is also increasing. Most of these off-line lithium batteries are not up to the standard for the use of electric vehicles because of their discharge time and discharge capacity. The discharge time and discharge capacity of some off-line lithium batteries can meet the power requirements of general electrical equipment, that is, most off-line lithium batteries can be reused, and we usually use off-line lithium batteries Used to replace the backup battery in the machine room. By using off-line lithium batteries to replace the original storage batteries in the computer room, the use cost of the computer room can be effectively reduced. However, the off-line lithium ...

AI Technical Summary

Problems solved by technology

However, the off-line lithium battery voltage system not only has the problem that the output current is prone to instability, but also has the problem that the output voltage cannot be directly used for the equipment in the computer room, and needs to be converted by other equipment, resulting in the cost of recycling the off-line lithium battery. Increased height, can not achieve the real purpose of saving the construction cost of the computer room
