Abstract

The invention discloses a battery pack and a battery pack system, wherein the battery pack includes: a plurality of cascaded rechargeable batteries, the positive pole of the upper-stage rechargeable battery is connected in series to the negative pole of the current-stage rechargeable battery, and the negative pole of the first-stage rechargeable battery is It is used to connect to the negative pole interface of the load, and the positive pole of the tail-stage rechargeable battery is used to connect to the positive pole interface of the load; the charge controller is connected in parallel to the positive and negative poles of each rechargeable battery; one end of each charge controller connected to the positive pole of the rechargeable battery is connected to Positive charging bus, each charging controller is connected to the negative terminal of the rechargeable battery and connected to the negative charging bus; the charging controller is used to provide an independent charging circuit for the rechargeable battery corresponding to the charging controller; the charging controller is used to control the battery corresponding to the charging controller. The working status of the rechargeable battery. The invention solves the problem of low battery performance caused by poor consistency in the prior art.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a battery pack and a battery pack system. Background technique [0002] Lithium-ion batteries have been widely used in the fields of 3C, electric vehicles and energy storage due to their advantages of high energy density, high voltage, long life, and low self-discharge. [0003] The application of lithium-ion batteries in the field of electric vehicles and energy storage is carried out in the form of battery packs, rather than working as a single battery. Working in the form of a battery pack, a key factor involved is the consistency of the battery. The cycle life of a single battery is good, but the life of the battery pack is not necessarily high, and it may even affect the safety of the battery pack, which is caused by the consistency of the battery. The high consistency of the battery is crucial to the normal operation of the battery pack. At present, in terms of...
