Abstract

The invention relates to an intelligent mixing apparatus and method for new and old batteries; the apparatus comprises a new battery pack connection end, an old battery pack connection end, a first collector, a second collector, a first servo unit and a second servo unit; positive and negative terminals of a new and old battery pack are used for respective connection with the positive and negative terminals of the new and old battery pack, the new and old battery pack connection ends are serially connected with the first and second servo units respectively to form a first branch and a second branch that are connected in parallel, the first servo unit and the second servo unit are used respectively for connecting or disconnecting the new and old battery pack connection ends to a charge circuit, the first collector is used for collecting state parameters of cells in anew battery pack respectively, and the second collector is used for collecting state parameters of cells in the old battery pack respectively. By using such scheme, battery overcharge problem is effectively avoided, adverse effect from new and old battery mixing is eliminated, and overall life of a battery pack is significantly extended since charging is precisely controlled.

Description

technical field [0001] The invention relates to a device and method for intelligently mixing old and new batteries, in particular to a device and method for mixing old and new batteries used in marginal base stations and node base stations in the communication industry, and belongs to the field of energy. Background technique [0002] In the field of energy, valve-regulated lead-acid batteries are generally used as backup power for mains power outages, and are widely used in important places such as communication base stations. [0003] In the scenario of a communication base station, the power supply system generally consists of a switching power supply and a battery. In most cases, the load is powered by the AC mains, and the lead-acid battery is supplied with charging power through the switching power supply, so that the battery is always in a floating charge state; when the mains power is cut off, the lead-acid battery seamlessly outputs power , supply power to the load...
