For convenience of understanding, some contents related to the embodiments of the present application are described below:
the battery system charging method of the embodiment of the application can be applied to any electronic equipment comprising a communication power supply system and a battery system, such as a communication base station and the like.
The electronic device may include: the communication power supply system and the battery system are electrically connected through the first switch, namely the first switch is electrically connected between the communication power supply system and the battery system. In some embodiments, the first switch may be provided independently as shown in fig. 1, and it is understood that in other embodiments, the first switch may be integrated in the communication power supply system or the battery system.
The communication power supply is provided with a power supply end for connecting an external power supply. In one specific implementation, the external power source may be a commercial power or a generator, etc.
The conducting (also referred to as closed) condition of the first switch may be: the power terminals of the communication power supply are connected with an external power supply, namely, the input of the external power supply and the output voltage of the battery system are detected. Under the condition that the input of the external power supply is detected and the voltage is output by the battery system, the first switch is conducted, and at the moment, the external power supply can charge the battery system through the communication power supply system; otherwise, the first switch performs an off (also referred to as open or closed) state. In one specific implementation, the first switch may be: a contactor, a relay, a single-pole double-throw switch or a field effect transistor, etc.
The battery system is a battery system with a power-off protection mechanism, and is characterized in that: after the battery system is discharged to the undervoltage, the voltage is not output to the outside. For the external output voltage, it can be understood that: the external output of the voltage is stopped, or the battery system is in a dormant state. In one particular implementation, the battery system may be a lithium ion battery system, a sodium ion battery system, a solid state battery system, or the like.
The following describes in detail a charging method for a battery system according to an embodiment of the present application with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart of a charging method for a battery system according to an embodiment of the present disclosure.
As shown in fig. 2, the battery system charging method may include the steps of:
step i, when the voltage of the battery system is smaller than a first threshold value, controlling the battery system to enter a dormant state, and starting a timer, wherein when the battery system is in the dormant state, the voltage is not output externally;
step ii, when the timing duration of the timer reaches a first duration, controlling the output voltage of the battery system;
step iii-1, when detecting an input of an external power source, turning on a first switch to enable the external power source to charge the battery system through the communication power source system, wherein the first switch is electrically connected between the communication power source system and the battery system;
or
And iii-2, when the external power supply input is not detected, the first switch is turned off, and the battery system is controlled to enter a dormant state.
According to the method for charging the battery system, after the battery system stops outputting voltage due to low voltage, the output voltage of the battery system can be controlled at regular time through a timer, after the output voltage of the battery system is controlled, when the input of an external power supply is detected, a first switch is conducted, so that the external power supply charges the battery system through a communication power supply system, wherein the first switch is electrically connected between the communication power supply system and the battery system; or, when the external power input is not detected, the first switch is turned off to control the battery system to enter the sleep state. The battery system can be activated at fixed time through the timer, a voltage activation interface and an activation line are not required to be arranged to activate the output voltage of the battery system, and on one hand, the increase of material cost is not involved; on the other hand, the load of the communication power supply system is not required to be occupied, and the resource utilization rate of the communication power supply system can be improved.
Specific implementations of the above steps are described below.
In step i, the battery system may include at least one battery (or referred to as a single cell). When the number of the batteries included in the battery system is greater than 2, voltages of different batteries may be different, and in this case, the voltage of the battery system being less than the first threshold may be specifically represented as: the total voltage of the battery system is smaller than a first threshold, or the lowest voltage of the battery system is smaller than the first threshold, or the voltage of any battery of the battery system is smaller than the first threshold. The first threshold may be a power-down protection voltage threshold of the battery system, or an undervoltage value of the battery system. The first threshold value is not particularly limited in the present application.
When the voltage of the battery system is smaller than the first threshold value, the battery system can be controlled to enter a dormant state to stop outputting the voltage to the outside for protecting the battery system. Additionally, a timer may be started to time activation of the battery system output voltage by the timer.
When the battery system enters the dormant state, the power-off protection mechanism can be started according to the battery system.
In step ii, when the timed duration of the timer reaches a first duration, the battery system may be activated, and the battery system is controlled to be in an activated state, wherein when the battery system is in the activated state, the voltage is output externally.
When the timing duration of the timer does not reach the first duration, the battery system can be controlled to be kept in a dormant state.
Therefore, in the embodiment of the application, after the battery system starts the power-off protection mechanism, the battery system can be activated at fixed time through the timer, and a voltage activation interface and an activation line are not required to be arranged to activate the output voltage of the battery system, so that on one hand, the increase of material cost is not involved; on the other hand, the load of the communication power supply system is not required to be occupied, and the resource utilization rate of the communication power supply system can be improved.
The first time length may be set according to actual requirements, for example, the first time length may be set to 10 seconds.
After controlling the battery system output voltage, it may be determined whether an external power input is detected, and a corresponding operation is performed based on the determination result. Step iii-1 is performed when an external power input is detected, and step iii-2 is performed when an external power input is not detected.
In step iii-1, when the voltage is output by the battery system and the external power input is detected, the conduction condition of the first switch is satisfied, so that the first switch may be controlled to be turned on, that is, the first switch is turned on, so that the external power may charge the battery system through the communication power supply system.
In step iii-2, the external power input is not detected at this time, and the on condition of the first switch is not satisfied, and therefore, the first switch may be controlled to be in the off state, that is, the first switch performs the off. In addition, in order to save the electric energy of the battery system, the battery system can be controlled to enter the dormant state again from the active state.
In some embodiments, step i may be performed by both the communication power system and the battery system, such as the battery system controlling the battery system to enter a sleep state, and the communication power system starting a timer. Step ii may be performed by a battery system. Step iii-1 may be performed by a communication power supply system or a battery system. Step iii-2 may be performed by the communication power system and the battery system together, for example, the battery system is controlled by the battery system to enter a sleep state, and the first switch is controlled by the communication power system or the battery system to be turned off. However, it should be understood that the execution main bodies of the steps in the foregoing embodiments are only examples, and are not limited thereto, and may be specifically set according to actual requirements, and the embodiments of the present application do not limit this.
In some embodiments of the present application, the method may further comprise:
after step iii-2, the timer is restarted and step ii, as well as step iii-1 or step iii-2, is repeated.
In this embodiment, after the battery system enters the sleep state, the battery system may be periodically activated by periodically starting the timer, so that when the battery system outputs a voltage and an input of an external power is detected, the first switch may be controlled to be turned on, and the external power may charge the battery system through the communication power system, thereby improving the charging reliability of the battery system.
It can be understood that the output voltage of the battery system may cause a voltage drop of the battery system itself, and in order to prevent the voltage of the battery system from dropping to 0 and causing the battery system to be unusable, the timer may be restarted only when a certain condition is met.
In some embodiments, the restarting the timer may include:
restarting the timer if a first condition is met;
wherein the first condition satisfaction may include at least one of:
1) The starting times of the timer in the second time length do not reach the starting time threshold value;
2) The voltage of the battery system is not less than a second threshold value, which is less than the first threshold value.
In some embodiments, the method may further comprise:
and controlling the timer to close if the first condition is not met.
In these embodiments, the conditions for periodically starting the timer are: the first condition is satisfied. That is, the timer may be started periodically if the first condition is satisfied; otherwise, the periodic timer can be stopped, and the first switch is controlled to be turned off, so that the voltage of the battery system is prevented from being reduced to 0, the battery system cannot be used, and the use safety of the battery system can be improved.
In a specific implementation, after performing step iii-2, it may be checked whether a first condition is met. In case the first condition is met, the timer may be restarted and step ii, and step iii-1 or step iii-2 may be repeatedly performed to improve the charging reliability of the battery system. In the case that the first condition is not met, the timer can be controlled to be closed, and the periodic starting operation of the timer is stopped, so that the use safety of the battery system is improved.
Each item of the first condition is explained below.
For 1), a threshold value of the number of starts of the timer may be preset, and the threshold value of the number of starts may be understood as the maximum number of starts. In an alternative implementation manner, the threshold of the starting times may be determined according to the voltage consumed by the battery system for one activation, and the first threshold may ensure that the voltage of the battery system does not drop to 0 after the battery system is periodically activated. In another optional implementation manner, the starting time threshold may be flexibly set according to requirements.
In a specific implementation, the number of times of starting the timer in the second time period may be counted and compared with the threshold of the number of times of starting.
Under the condition that the starting times do not reach the starting time threshold, the timer can be started continuously and periodically until the first switch is conducted, or the timer is closed when the starting times reach the starting time threshold.
In the case that the number of times of starting reaches the threshold value of the number of times of starting, the timer may be aborted, that is, the periodic starting action of the timer is stopped, and the timer is controlled to be closed.
The second time length can be flexibly set according to actual requirements. In an alternative implementation, the starting time of the second time period may be a time when the voltage of the battery system is less than the first threshold, but is not limited thereto.
For 2), a second threshold may be set in advance. In an alternative implementation, the second threshold may be a minimum voltage at which the battery system supports charging from the external power source, that is, if the voltage of the battery system is less than the second threshold, the external power source cannot charge the battery system even if the first switch is turned off and the external power source is input. Of course, to further protect the battery system, the second threshold may be greater than the minimum voltage at which the battery system supports charging from the external power source. Or the second threshold value can be flexibly set according to actual requirements, but the second threshold value is smaller than the first threshold value.
In particular implementations, the voltage of the battery system may be compared to a second threshold.
In the case that the voltage of the battery system is not less than the second threshold, the timer may continue to be periodically started until the first switch is turned on, or the timer is turned off when the voltage of the battery system is less than the second threshold.
In case the voltage of the battery system is smaller than the second threshold, the timer may be aborted, i.e. the periodic starting action of the timer is stopped, and the timer is controlled to be turned off.
In some embodiments of the present application, a timed activation function of the battery system may be provided. And b, after the timing activation function of the battery system is started, the battery system can be activated at regular time by starting a timer, and the step i is executed, otherwise, the timer can be always in a closed state. In these embodiments, the method may further comprise:
before step i, receiving indication information;
starting a timing activation function of the battery system in response to the indication information;
wherein the indication information is used for indicating any one of the following items:
a) Starting a timed activation function of the battery system;
b) And determining to start the timing activation function of the battery system under the condition that the anti-battery reverse connection mode of the communication power supply system is a target mode.
Further, the on condition of the first switch corresponding to the target mode may be: an external power input is detected, as well as an output voltage of the battery system.
In this embodiment, whether to start the timed activation function of the battery system may be decided based on the specific indication content of the indication information. In an optional implementation manner, the indication information may be sent by an upper computer, and the upper computer may be a notebook carried by a serviceman of the electronic device.
In this embodiment, the indication information may have at least the following two expressions:
the first expression can directly indicate whether to start the timing activation function of the battery system through the indication information. In this case, if the indication information indicates start-up, the start-up may be performed; otherwise, it may not be started.
In the second expression, the timing activation function of the battery system is determined to be started when the battery reverse connection prevention mode of the communication power supply system is indicated as the target mode through the indication information. In this case, the starting the timing activation function of the battery system in response to the indication information may include:
in response to the indication information, determining whether a battery reversal prevention mode of the communication power supply system is the target mode;
and starting a timing activation function of the battery system when the anti-battery reverse connection mode of the communication power supply system is the target mode.
It is to be understood that the timing activation function of the battery system may not be started when the battery reverse connection preventing mode of the communication power supply system is not the target mode.
When the anti-battery reverse connection mode of the communication power supply system is the target mode, the communication power supply system can be considered to be of a type for preventing the battery reverse connection in a hardware mode.
In this embodiment, the timing activation function of the battery system may be regarded as a switch, and may be flexibly turned on and off according to the specific indication content of the indication information, so that the flexibility of use of the timing activation function of the battery system may be improved.
It should be noted that, in the embodiments of the present application, various optional implementations that are described in the embodiments of the present application may be implemented in combination with each other or may be implemented separately without conflicting with each other, and the embodiments of the present application are not limited to this.
For ease of understanding, the following is illustrated in connection with FIG. 3:
in fig. 3, the battery system is represented as a lithium battery system including lithium batteries 1 to X. The lithium batteries 1-1 are connected to a communication power supply system through BAT 1-BATx, and the communication power supply system controls whether the lithium battery system is connected to the communication power supply system through a battery branch contactor (KM 1) to charge or discharge.
KM1 is aforementioned first switch promptly, and only when lithium battery system output voltage is correct, KM1 just can be closed, and lithium battery system just can insert and charge in the communication power supply system. When no commercial power is available, the lithium battery system discharges to the undervoltage state (the lithium battery system has no output voltage under the undervoltage state). After the commercial power comes, the communication power supply system is electrified, because of the undervoltage of the lithium battery system, no output voltage exists, the KM1 cannot be closed, the lithium battery system cannot be connected into the communication power supply system to be charged, and the electric function of the lithium battery system is caused to fail.
In order to solve the problem that a lithium battery system cannot be accessed to a communication power supply system for charging due to the fact that the lithium battery system is under-voltage and has no output voltage after the mains supply, the embodiment of the application provides a strategy for timing activation of the lower power supply of the battery system.
Battery Management System (BMS) software of the lithium Battery System is increased: (1) a low power consumption state (which may also be referred to as a shutdown state or a sleep state, in which a Micro Controller Unit (MCU) is powered off if there is a complete power down, the complete power down is shutdown), (2) a power-off under-voltage timing activation function switch (default off), (3) a power-off under-voltage timing activation time interval (default X hours).
Step one, after the communication power supply system is confirmed to be of a type preventing reverse connection of batteries in a hardware mode, the power-off timing activation function of the lithium battery system is turned on by the upper computer.
The communication power supply system is of a type of preventing reverse battery connection in a hardware mode, namely the communication power supply system is used for preventing the reverse battery connection as a target mode.
And step two, when no commercial power exists, the lithium battery system discharges to supply power to the load, the lithium battery system automatically enters a low power consumption state (a dormant state) after being undervoltage, and the lithium battery system does not have output voltage at the moment.
And step three, after the mains supply comes, the communication power supply system supplies power to the load branch, and the communication power supply system detects that the voltage of the lithium battery system is incorrect and cannot close the KM1. After a period of time, the lithium battery system starts immediately after the timing starting time, the lithium battery system starts to output voltage externally, the communication power supply system closes the KM1 after detecting that the output voltage of the lithium battery system is correct, and the lithium battery system is connected into the communication power supply system for charging.
Therefore, by adopting the undervoltage power-off timing activation strategy, on one hand, a voltage activation port and a circuit of the lithium battery system can be eliminated, a cable between the port and a communication power supply system is eliminated, and the cost is reduced. On the other hand, the idle resource occupying important loads of the communication power supply is avoided.
