Detailed Description
The core of the invention is to provide a management method, a system and a device of BBU, which can ensure that the residual electric quantity of the battery as a management reference is accurate, thereby improving the reliability of the battery management work and further improving the power supply reliability of the BBU.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a BBU management method according to an embodiment of the present invention.
The management method of the BBU comprises the following steps:
step S1: and acquiring a battery residual electric quantity acquisition value of the BBU.
Step S2: judging whether the residual electric quantity acquisition value of the battery is credible according to a preset electric quantity evaluation strategy; if not, step S3 is executed.
It should be noted that the preset of the present application is set in advance, and only needs to be set once, and the reset is not needed unless the modification is needed according to the actual situation.
Specifically, considering that the battery residual capacity of the BBU collected by the metering chip is not necessarily accurate data, if the battery residual capacity collected by the metering chip is not accurate, the reliability of battery management work related to the battery residual capacity may be reduced, so the method and the device first obtain the battery residual capacity collection value of the BBU from the metering chip, and then judge whether the battery residual capacity collection value is credible according to a preset capacity evaluation strategy so as to check the accuracy of the battery residual capacity collection value when the battery residual capacity collection value is not credible.
More specifically, the power evaluation policy of the present application may include: 1) if the residual battery capacity acquisition value is far higher than the battery rated capacity of the BBU, the residual battery capacity acquisition value is not credible; 2) if the battery residual electric quantity acquisition value suddenly drops to exceed a certain value when the BBU is not discharged, the battery residual electric quantity acquisition value is not credible; 3) if the battery residual capacity collection value is not reduced after the BBU is discharged seriously, the battery residual capacity collection value is not trusted … …. Therefore, the purpose of the power evaluation strategy is to prove that the residual power of the battery collected by the metering chip can not be trusted, and particularly, the collected value of the residual power of the battery is not trusted when the condition of the power evaluation strategy is met.
Step S3: and acquiring data information of the BBU electric parameters, and calculating the actual value of the battery residual electric quantity of the BBU according to the data information.
Specifically, when the battery residual capacity acquisition value is not credible, the method and the device for acquiring the battery residual capacity acquire data information (such as voltage and current data) of the BBU electric parameter aim to calculate the actual value of the battery residual capacity of the BBU according to the data information of the BBU electric parameter, and the actual value of the battery residual capacity is used as a check value for checking whether the battery residual capacity acquisition value is accurate or not so as to judge the accuracy of the battery residual capacity acquisition value subsequently.
Step S4: judging whether the deviation between the acquired value of the residual battery capacity and the actual value of the residual battery capacity is greater than a preset deviation threshold value or not; if yes, go to step S5; if not, step S6 is executed.
Step S5: and managing the BBU according to the actual value of the residual electric quantity of the battery.
Step S6: determining that a BBU has a fault.
Specifically, it can be understood that if the difference between the battery remaining capacity acquisition value and the actual value of the battery remaining capacity is small, the battery remaining capacity acquired by the metering chip is considered to be accurate, but the BBU has a fault; if the difference between the battery residual capacity acquisition value and the actual value of the battery residual capacity is large, the battery residual capacity acquired by the metering chip is considered to be inaccurate, and the actual value of the battery residual capacity is more suitable for being used as the battery residual capacity of the BBU.
Based on this, after the actual value of the battery residual capacity of the BBU is obtained through calculation, the deviation between the acquired value of the battery residual capacity and the actual value of the battery residual capacity is obtained, if the deviation between the acquired value of the battery residual capacity and the actual value of the battery residual capacity is larger than a preset deviation threshold value, the battery residual capacity acquired by the metering chip is considered to be inaccurate, the actual value of the battery residual capacity is used as the battery residual capacity of the BBU, and the BBU is managed according to the actual value of the battery residual capacity, so that the reliability of battery management work is improved. And if the deviation between the battery residual capacity and the battery residual capacity is not greater than the preset deviation threshold value, determining that the BBU has a fault to remind a user to maintain or replace the BBU.
The invention provides a management method of BBU, which comprises the steps of obtaining a battery residual electric quantity acquisition value of the BBU, and judging whether the battery residual electric quantity acquisition value is credible according to a preset electric quantity evaluation strategy; if the BBU power parameter is not credible, acquiring data information of the BBU power parameter, and calculating an actual value of the battery residual capacity of the BBU according to the data information; judging whether the deviation between the acquired value of the residual battery capacity and the actual value of the residual battery capacity is greater than a preset deviation threshold value or not; if so, managing the BBU according to the actual value of the residual electric quantity of the battery; and if not, determining that the BBU has a fault. Therefore, when the battery residual capacity acquisition value is not credible, the accuracy of the battery residual capacity acquisition value is verified by calculating the battery residual capacity so as to ensure that the battery residual capacity serving as a management reference is accurate, so that the reliability of battery management work is improved, and further the power supply reliability of the BBU is improved.
On the basis of the above-described embodiment:
as an optional embodiment, the management method further includes:
when the BBU enters charging, acquiring the actual temperature of the environment where the BBU is located;
determining a target charging current and a target charging voltage corresponding to the actual temperature according to the corresponding relation of the preset temperature electrical parameters;
and charging the BBU according to the target charging current and the target charging voltage.
Specifically, the charging process of the BBU comprises two stages of constant-current charging and constant-voltage charging, and the corresponding relation (temperature electrical parameter corresponding relation for short) between the temperature of the environment where the BBU is located and the charging current and the charging voltage of the BBU is reasonably set in advance by considering different charging rates of the BBU at different temperatures so as to charge and use the BBU for the subsequent BBU.
Based on the method, when the BBU is charged, the actual temperature of the environment where the BBU is located is firstly obtained, and then the target charging current and the target charging voltage of the BBU corresponding to the actual temperature of the environment where the BBU is located are determined according to the preset temperature electrical parameter corresponding relation, so that the constant-current charging stage of the BBU is controlled according to the target charging current, and the constant-voltage charging stage of the BBU is controlled according to the target charging voltage.

if so, the control target cell stops charging and the control target cell discharges to the second cell.
Further, the battery pack of the BBU of the present application is composed of a plurality of identical battery cells, and each battery cell needs to be charged in an equalizing manner in the BBU charging process, that is, the electric quantity of each battery cell is identical. Based on this, in the BBU charging process, the power information of each battery cell is acquired, the power information of the multiple battery cells is added to obtain the total power information of the multiple battery cells, and then the average power information of the multiple battery cells is obtained by dividing the total power information of the multiple battery cells by the total number of the multiple battery cells. After the average electric quantity information is obtained, comparing the electric quantity information of the multiple single batteries with the average electric quantity information to divide the multiple single batteries into a first single battery with an electric quantity value larger than the average electric quantity information and a second single battery with an electric quantity value smaller than the average electric quantity information, then subtracting the average electric quantity information from the electric quantity information of the first single battery to obtain an excess electric quantity value of the first single battery, and determining a target single battery with the excess electric quantity value larger than a preset excess threshold value from the first single battery. After the target single battery is determined, the target single battery is controlled to stop charging, and the target single battery is controlled to discharge to the second single battery, so that the multiple single batteries are charged in an equalizing mode.
As an optional embodiment, the management method further includes:
and when the lasting undischarged time of the BBU exceeds a preset time threshold, controlling the BBU to perform internal discharge according to a preset internal discharge strategy.
Further, considering that the battery activity of the BBU is reduced and the battery capacity of the BBU is rapidly reduced when the BBU is not discharged for a long time, the present application starts timing from the end of each BBU discharge, and when the timing time exceeds a preset time threshold, if the BBU is not discharged, the BBU is controlled to perform internal discharge according to a preset internal discharge strategy (i.e., a discharge voltage and a discharge current are set according to a cell material), thereby realizing the internal discharge of the BBU at regular time and ensuring the battery activity of the BBU.
As an optional embodiment, the management method further includes:
judging whether the battery voltage of the BBU is lower than a preset full charge voltage or whether the battery residual electric quantity of the BBU is lower than a preset primary power-down protection electric quantity;
and if the voltage is lower than the preset full charge voltage or the preset primary power-down protection electric quantity, charging the BBU.
Further, the present application sets two charging strategies in advance: 1) when the battery voltage of the BBU is lower than the preset full charge voltage, charging the BBU; 2) and charging the BBU when the residual battery power of the BBU is lower than the preset primary power-down protection power to ensure that the BBU supports at least one primary power-down protection.
Based on the method, when the BBU is on line, the battery voltage of the BBU is obtained, the battery voltage is compared with the preset full charge voltage, and if the battery voltage is lower than the preset full charge voltage, the BBU is charged; and meanwhile, acquiring the residual battery capacity of the BBU (if the residual battery capacity acquired by the metering chip is accurate, the acquired value of the residual battery capacity is used as the residual battery capacity of the BBU, if the residual battery capacity acquired by the metering chip is not accurate, the actual value of the residual battery capacity is used as the residual battery capacity of the BBU), comparing the residual battery capacity with the preset primary power-down protection capacity, and if the residual battery capacity is lower than the preset primary power-down protection capacity, charging the BBU.
As an optional embodiment, the management method further includes:
storing the core data of the BBU in a system memory;
and when the BBU has a problem, reading the core data from the system memory, and analyzing the problem of the BBU according to the core data.
Further, the present application may also store VPD (Voltage protection device) information (i.e., core data, such as battery ID (Identity) and battery full charge capacity) representing the operating condition of the BBU in the system memory. When the BBU has a problem, the VPD information can be read from the system memory so as to analyze the problem of the BBU according to the VPD information.
In addition, the system can interact with an upper computer to send prompt information to the upper computer, such as information that the service life of the battery is about to end, information that whether the BBU supports primary power-down protection, information that whether the BBU is on-line and information that whether the environment where the BBU is located meets the charging and discharging environment, so that a user can check the prompt information.
