A battery pack detachable mobile power supply

Abstract

The invention discloses a battery pack detachable mobile power supply, which comprises a power supply management module and at least one battery unit, and is characterized in that the battery unit and the power supply management module are connected into an integral power supply through a connecting piece; the power supply management module is internally provided with a control circuit, the control circuit is provided with a DC buck / boost unit, a charge and discharge protection unit, a reverse connection and short circuit protection unit and a charge and discharge indicating circuit, and a shell of the power supply management module is provided with a charge interface, a master switch and a power supply output interface. The mobile power supply disclosed by the invention has the advantages that firstly, a failure unit is directly removed when the power supply breaks down, and the rest part always operates normally; secondly, the whole mobile power supply is detachable, lighter in weight and portable, and can be taken by one person to an accident spot and assembled quickly within five minutes so as to realize power supply; thirdly, if a single battery unit is damaged, only the damaged part is required to be replaced, and the maintenance cost is low; and fourthly, the mobile power supply has no carbon emission, is more environment-friendly, and does not increase the cost.

Description

technical field [0001] The invention relates to the technical field of power supply equipment, in particular to a mobile power supply. Background technique [0002] Backup power is applied in many fields, such as communication base stations. Communication base stations, including many micro 4G base stations widely distributed in buildings and other places, will immediately switch to the power supply state of backup batteries after encountering a power outage. However, when the performance of the battery deteriorates and the stored power cannot meet the continuous power supply, the base station will face the problem of stopping the station. Many base stations not only provide wireless services for the area, but also undertake signal relay functions. Therefore, once the backup battery supervisory system issues an alarm, the power generation personnel will send the generators to the vicinity of the base station to generate electricity. However, generators have the disadvanta...

AI Technical Summary

Problems solved by technology

However, generators have the disadvantages of inconvenient movement, excessive manpower investment, use of diesel / gasoline, high operation and maintenance costs, disturbing noise, and not being environmentally friendly.

Since many base stations are located in densely populated places, it is difficult for vehicles to enter or oil engines to pollute the environment are not allowed by residents or units, and lead-acid battery packs are used, but the power supply time is often short, resulting in the inability to guarantee the power supply of the base station, resulting in base station power outage communication accident

And the existing backup battery pack is designed as a whole group, the disadvantage is that when the power supply fails, the whole group cannot be used; it is not removable, heavy, and inconvenient to move; when damaged, it needs to be replaced as a whole, which is costly and uneconomical
