Battery factory voltage limiting method and device

Abstract

The invention discloses a battery factory voltage limiting method and device. The device comprises a voltage limit setting module, a battery interface and a control module, wherein the voltage limit setting module is used for setting a matched battery factory voltage limiting range in advance according to the characteristics of different batteries; the factory voltage limiting range comprises an upper limit voltage and a lower limit voltage; the battery interface is used for connecting an anode and a cathode of the battery and the device; and the control module is used for starting the device, carrying out discharging or charging on the battery which is connected with the device and closing the device when detecting that the battery voltage is within the factory voltage limit range. The factory battery is connected with the device disclosed by the invention, so that the factory battery voltage is controlled within the matched factory voltage limiting range by the device; the safety of the battery in a transportation process is facilitated; maintenance of the battery voltage is also facilitated; the labor cost for inspecting the battery voltage before leaving the factory can be reduced; and the inspection accuracy is also ensured.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a method and device for limiting the factory voltage of batteries. Background technique [0002] At present, rechargeable batteries have been widely used in portable devices such as mobile phones and notebook computers. For a device with a detachable battery, the battery and the device are usually placed in a packaging box separately to ensure transportation safety. Because it takes a long time for the battery to reach the customer after leaving the factory, as a chemical substance, the voltage of the battery needs to be limited within a certain range when it leaves the factory. This range is not only conducive to the safety of the battery during transportation, but also It is conducive to the maintenance of battery voltage; if the battery voltage is too high when leaving the factory, the battery is easy to bulge or even explode during transportation; if the battery voltage is...
