in this step, as regards the activation voltage, for example, the various voltage levels of the series of lithium iron phosphate batteries 15 to 20 include: 40V, 57.6V and 72V, and can be configured according to practical application scenes; as regards the activation current, it is a small activation current, which may be, for example, a current smaller than 3A.
Charging control step S30: and when the communication activation condition is met, controlling a charger to carry out charging management on the battery.
In the embodiment, after the battery is put into the bin, the connector is inserted and the door is closed, communication is activated firstly, and if the communication activation is successful, the battery can be directly charged and controlled; and if the communication activation is unsuccessful, performing charging activation, and controlling the charger to gradually increase the output activation voltage until the battery exits from the sleep low-power consumption state when the charging is activated. Therefore, the single-bin charging management method can adaptively activate and identify the undervoltage dormant batteries with different voltage grades, namely, the battery bin of the charging and replacing cabinet can support charging of various types of batteries, so that the utilization rate of the charging and replacing cabinet is improved, and the user experience is improved.
Fig. 2 is a flowchart of a second embodiment of the single-bin charging management method of the present invention, which is applied to a bin control board, and when a battery is placed in a battery bin, a connector is inserted, and a door is closed, the following steps are performed:
step S11, judging whether communication connection can be established with the battery within a first preset time period (for example, 10S), if so, determining that a communication activation condition is met, and then executing step S31; if not, go to step S12;
s12, judging whether the current activation times exceed preset times, if so, executing S35; if not, it is determined that the communication activation condition is not satisfied, and then step S21 is performed. In this step, it should be noted that the initial value of the current activation number is 0, and the activation number is increased by 1 every time the charging activation is performed. The preset number of times is, for example, 3.
S21, determining the activation voltage of the corresponding voltage grade according to the current activation times, and controlling a charger to output the activation voltage and the activation current of the corresponding voltage grade to a battery, wherein the determined voltage grade is positively correlated with the current activation times;
and S22, adding 1 to the current activation times, and then executing the step S11.

step S37, judging whether the current door state is changed into a door closing state within a second preset time period, if so, executing step S11; if not, go to step S37;
step S38, judging whether the charging recovery condition is met, if so, executing step S11; if not, step S38 is executed.
Further, between step S33 and step S34, the method further includes: in the charging process, controlling the charger to adjust the output charging voltage/current according to the charging voltage/current adjustment request information received from the battery at regular time; or, in the charging process, the charger is automatically controlled at regular time to adjust the output charging voltage/current.
In addition, the charge permission conditions include: the battery does not report faults currently; the highest voltage of the battery electric core does not exceed a first allowable value; the current soc value of the battery does not exceed the second allowable value; the charger has no operation fault;
the charge stop condition includes at least one of: the battery is fully charged; the bin state is a door opening state; the battery requests to stop charging; the charging time is overtime; reporting a fault by the battery; a charger failure;
the charge recovery condition includes: recovering the battery failure; recovering the fault of the charger; communication interruption is recovered; the current soc value of the battery is below the threshold.
In the embodiment, the battery data is inquired regularly during the operation of the bin control panel, and the communication is kept active all the time. After a connector is inserted into a battery compartment and a door is closed after a battery is placed in the battery compartment, communication activation is carried out for 10s, and if communication is established, the self-adaptive identification stage is exited; if the communication can not be established, an adaptive identification phase is entered. During the adaptive identification phase, the activation voltage is increased step by step, and the adaptive activation phase is exited prematurely as long as communication with the battery is established. For example, an activation voltage and a small activation current of 40V are output to the battery at the first activation, and then it is judged whether or not a communication connection can be established with the battery, if not, an activation voltage and a small activation current of 57.6V are output to the battery at the second activation, and then it is judged whether or not a communication connection can be established with the battery, and if not, an activation voltage and a small activation current of 72V are output to the battery at the third activation, and then it is judged whether or not a communication connection can be established with the battery. Therefore, for the battery which is in under-voltage dormancy at the voltage grade of 40V, the communication connection can be established with the battery when the battery is activated for the first time; for the battery which is in under-voltage dormancy at the voltage level of 57.6V, communication connection can be established with the battery when the battery is activated for the second time; for an under-voltage dormant battery with a 72V voltage level, a communication connection can be established with the battery when the battery is activated for the third time. Thus, undervoltage hibernated batteries of different voltage classes may be activated.
After the connection with the battery is established, firstly, whether a bin gate is closed and whether the operation state in the bin meets the charge permission condition (for example, the current failure of the battery is not reported, the highest voltage of a battery cell does not exceed a permission value, the current soc does not exceed a permission value, the operation state of a charger is good, and the like) is judged, if yes, the charging is started, and if not, the charging is stopped and a stage to be recharged is started.
And after the charging is started, sending an instruction to a charger to control the output voltage and the maximum output current of the charger. In the charging process, the charging voltage and the maximum output current are adjusted at regular time before the charging stop condition is not triggered. It should be noted that, if the battery supports the charging request function and the function is already turned on, the battery periodically sends an instruction to the bin control board to request adjustment of the charging voltage and the maximum charging current limit value. Otherwise, the warehouse control management system performs charging adjustment according to the own logic. In addition, after the maximum charging current limit is set, the charger starts to perform constant-current charging, the charging stage is automatically changed into constant-voltage charging, and the charging current is gradually reduced until the charging is stopped.
In the charging process, the satisfaction of charging stop conditions (such as full battery, door opening, battery pack stopping request, charging time overtime, battery pack reporting fault, charger fault and the like) is waited, and if the charging stop conditions exist, a shutdown instruction is sent to the charger to stop charging.
After stopping charging, waiting for the user to take the battery, wherein the bin gate is in an open state, and when the door is detected to be in the open state, waiting for the door to be in a closed state again. In the process, the user closes the door after finishing taking or putting the battery or having no operation by himself, and then the next cycle charging is carried out again.
After stopping charging, if the user does not take the battery, at this time, it is determined whether the charge recovery condition is satisfied (for example, the battery failure recovery, the charger failure recovery, the communication interruption recovery, the battery soc decreasing to the set value, etc.), and if the battery is stopped in the bin, the door is in a closed state, and the charge recovery condition is satisfied, the next cycle charging is required again.
The single-bin charging management method of the embodiment has the following beneficial effects:
1. the activation recognition of the battery pack in various types of dormant states is simply, efficiently and stably supported;
2. if the charging permission condition is not met before charging, charging can be prohibited, the charging voltage and the charging current can be adjusted regularly in the charging process, and charging can be stopped in time in a full charging or fault state or door opening state, so that stable operation of equipment and personal safety of users can be ensured;
3. the battery stops charging due to fault reasons, and charging can be automatically recovered after the fault is relieved.
The invention also constructs a warehouse control board, which comprises a processor and a memory stored with a computer program, wherein the processor realizes the single-warehouse charging management method when executing the computer program.
The invention also constitutes a readable storage medium storing a computer program which, when executed by a processor, implements the above-described single-bin charge management method.
