Problems solved by technology

However, the voltage of a fully charged battery pack is usually higher than that of a battery pack that has been discharged to a certain extent on site, so when it is charged and connected, it will produce a strong ignition phenomenon, the impact current is very large, it is very unsafe, and the original battery will be damaged. charging, resulting in unnecessary battery charge and discharge loss

Abstract

The invention discloses a mobile emergency power supply for communication and a voltage self-adaptation method thereof. The mobile emergency power supply includes a charging module, a storage battery pack, a switch, a DC voltage regulator module, and a monitoring board; wherein a positive electrode and a negative electrode of an output end of the charging module, a positive electrode and a negative electrode of the storage battery pack, and a positive electrode and a negative electrode of an input end of the DC voltage regulator module are connected in parallel, and the switch is connected in series between the storage battery pack and the DC voltage regulator module to form a main loop; and the monitoring board is connected with the DC voltage regulator module by a communication line to form a control sub-system. According to the invention, the monitoring board can control the output voltage of the DC voltage regulator module and can allow the output voltage of the DC voltage regulator module to be approximately equal to the current work voltage of an original system when the output voltage of the DC voltage regulator module accesses the original communication power supply system, in such a way that sparking and impact during access due to a big circulating current between the two sets of batteries can be effectively avoided, and the unnecessary electric energy loss due to mutual charging can be avoided. The emergency power supply can be accessed to prolong the system power supply time without any change and operation of the original power supply, and the operation is simple and reliable.

Description

technical field [0001] The invention relates to communication power supply technology, in particular to a mobile emergency power supply for communication and a voltage adaptive method thereof. Background technique [0002] Many important precision electrical equipment such as communication equipment are directly powered by DC, and their power comes from the AC power grid and is converted into stable and clean DC power through a rectifier power supply device. In order to ensure the continuous and uninterrupted work of the main equipment, the communication power supply system is usually connected in parallel with battery packs. When the AC power grid fails, the battery pack can immediately supply power to the load equipment because of the direct parallel connection with the rectified power supply and the load equipment, thereby ensuring that the load equipment is not affected by the external power failure. [0003] However, the capacity of the battery pack is limited, and whe...
