Abstract

A control circuit for preventing a battery group (101) from being reversely connected includes a normally-open contactor (102), a first normally-open relay (103), a first diode (104), a second diode (105), a second normally-open relay (106), a third diode (107) and a controller (111). By sending a control command, the controller (111) controls the control coil of the second normally-open relay (106) to work or not to work, thus controls the normally-open contactor (102) to turn on or off, so that the battery group (101) being protected can be connected with or disconnected from a power supplysystem for a base station. The power supply system for a base station is also provided. With the control circuit, the battery group can be automatically connected to or disconnected from the power supply system for the base station, and a battery group with medium or high capacity can be disconnected from the power supply system in time when the battery group is reversely connected, thus protecting the normal work of the system.

Description

technical field [0001] The invention relates to the technical field of power supply control, in particular to a battery pack anti-reverse connection control circuit and a base station power supply system. Background technique [0002] In a high-power base station power supply system, it is often necessary to configure one or more sets of large-capacity battery packs as backup power to supply power to base station equipment. Medium and large-capacity base station power supplies often need to provide a current of tens to hundreds of amperes, and the configured battery packs generally have hundreds of amperes. [0003] For medium and large-capacity base station power supplies, ordinary diode anti-reverse connection circuits or MOS tube-controlled anti-reverse connection circuits are no longer suitable. If the battery is accidentally reversed, it is equivalent to a short circuit, that is, a huge instantaneous current will be generated. If it is not protected, it will inevitabl...
