Embodiment Construction

[0035] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0036] Such as figure 1 As shown, in the battery pack verification method provided in this embodiment, after the verification operation is started, the battery pack can be internally discharged with the minimum current. During the discharge process, the voltage will decrease as the battery capacity decreases. Characteristics, the ratio of voltage to battery capacity is constant, when the capacity of the capacitor is 50%, the voltage is a certain constant value V, and enough power is left at the same time, so that when the system is suddenly powered off during the verification process, the battery can provide the system with normal power. run. The current monitoring module can detect the magnitude of the cu...

Abstract

The invention discloses a battery set verification method, device and system. The method comprises steps that a discharging start instruction for a battery set is emitted, and the battery set discharges; magnitude of a discharging current is monitored, and statistics of discharging capacity is carried out; a voltage of the battery set is monitored according to the discharging capacity, when the voltage of the battery set responds to a set voltage threshold, a discharging stop command is emitted, and the battery set stops discharging; the discharging capacity acquired through statistics is compared with preset battery set capacity, if conditions are satisfied, the battery set is normal; if the conditions are not satisfied, the battery set is abnormal. The verification device comprises a discharging module, a current monitoring module, a voltage monitoring module and a battery set state determination module. The verification system comprises a main board and a BBU assembly. The method isadvantaged in that intelligent verification of the lithium ion battery set in the BBU is realized, normal use of the battery set is guaranteed, and normal operation of the system after power failureis guaranteed.

Description

technical field [0001] The invention relates to the field of battery calibration, in particular to a battery pack calibration method, device and system. Background technique [0002] In order to ensure the stable operation of the server, in addition to being powered by the PSU, the main board of the server is generally equipped with a BBU (Battery Backup Unit, battery backup unit) to prevent the system from being affected by power failure. The BBU is generally powered by a lithium-ion battery pack, and once the power supply of the battery pack is insufficient or abnormal, it cannot guarantee the power supply to the server motherboard after the system is powered off. Contents of the invention [0003] In order to solve the above problems, the present invention provides a battery pack verification method, device and system to ensure that the corrected battery pack can provide enough circuits for the system to ensure the normal operation of the system after power failure, whi...
