Detailed Description
The embodiments of the present invention will be further described with reference to the accompanying drawings.
In the embodiment of the charging control method and device for single battery in the centralized charging cabinet, the centralized charging cabinet comprises a plurality of battery charging spaces, each battery charging space is provided with a separate cabinet door and a charging control unit, of course, the whole centralized charging cabinet is also provided with an integral control device which controls the whole centralized charging cabinet, and the integral control device comprises the opening of the cabinet door of each battery charging space, the power supply of the control unit of each battery charging space, information interaction, the state collection and display of each battery charging space in the centralized charging cabinet and the like. And can also control some equipment specific to the centralized charging cabinet, such as air conditioning equipment, fire fighting equipment and the like. Of course, the centralized charging cabinet is also responsible for uploading the state information of the centralized charging cabinet to an upper computer (if any). In this embodiment, as shown in fig. 1, a typical charging procedure for a battery to be charged in a battery charging space disposed in the centralized charging cabinet is as follows:
step S11, judging whether the battery is put in place or not and whether the cabinet door is closed or not, if so, executing the next step; if not, the process goes to step S18. It should be noted that the above determination actually includes two determinations, one is whether a battery (here, a battery to be charged) is placed in place, and the other is whether a cabinet door is closed, and the next step is executed only when the battery to be charged is placed in place and the cabinet door is closed; if either condition is not satisfied, for example, the cabinet door is not closed or the battery to be charged is not put in place, the process goes to step S18. In this embodiment, whether the battery to be charged is placed in place is determined by whether a tact switch is triggered, where the tact switch is placed at the end of the battery charging space (i.e., the end opposite to the cabinet door), and when the battery to be charged is pushed into the battery charging space accurately, the tact switch is triggered to emit a signal indicating that the battery to be charged is placed in place; and whether the cabinet door is closed or not is indicated by a state switch installed in the electric control lock corresponding to the cabinet door, and similarly, when the cabinet door is locked, the state switch sends a cabinet door locking signal. Therefore, in this step, the control device of the centralized charging cabinet actually detects whether the two switches in the battery charging space output signals or not for the judgment of whether the battery to be charged is placed in place and whether the cabinet door is closed or not, and if so, the next step can be executed; if any of the signals is not detected, the judgment is no and the process goes to step S18.
Step S12 powers up the control unit of the battery charging space, secures the battery: in this step, the information that the battery to be charged is in place and the cabinet door is closed is obtained through the previous step, so the control device of the centralized charging cabinet switches on the commercial power for the control unit of the battery charging space, that is, the control device of the centralized charging cabinet supplies the externally input commercial power to the control unit of the battery charging space, and powers on the control unit. In this embodiment each battery charging space is provided with its own control unit which provides charging power to the batteries to be charged in the battery charging space and controls the charging process. When the battery charging space is empty or the battery therein is charged, the control unit is disconnected from the mains supply, and the mains supply is connected only when the battery to be charged therein needs to be charged. This is because it is necessary to calculate the amount of electricity for charging a battery, which is convenient for commercial operation; meanwhile, the arrangement is safe. After the battery is charged, the control unit of the battery charging space starts to work after initialization is completed, and preparation is made for charging the battery to be charged. Then, the control unit drives the positioning structure of the battery charging space to act, so that the battery is fixed in the battery charging space. In this embodiment, the positioning structure is a shifting piece driven by a motor installed at a proper position, and the control unit controls the motor to rotate such that the shifting piece rotates and protrudes out of a designated portion of the battery, such as one end of the battery, to block an access passage of the battery charging space, so as to limit the battery to be charged in the battery charging space, so that the battery cannot exit the battery charging space through the access passage, thereby achieving the effect of fixing the battery to be charged in the battery charging space.
Step S13 acquires environmental parameters and battery status parameters: in this step, the control unit collects environmental parameters of the battery charging space and state parameters of the battery; in this embodiment, collecting the environmental parameter of the battery charging space comprises collecting output signals of a temperature sensor and a smoke sensor arranged in the battery charging space. In other words, the temperature sensor and the smoke sensor are arranged in the battery charging space and connected with the control unit, and the control unit receives data output by the sensors before the battery to be charged is charged, so as to acquire environmental parameters and battery state parameters. The battery state parameters are obtained by applying an appropriate load or voltage to the battery to obtain the current voltage and current parameters.
Step S14 drives or does not drive the corresponding device to work according to the environmental parameters: in the step, the control unit controls the relevant actuating mechanism to work according to the acquired environmental parameters of the battery charging space so as to improve or adjust the state of the battery charging space; basically, in this embodiment, the step may include: converting the output signal of the temperature sensor in the obtained environmental parameters into a temperature value, and uploading the temperature value to a control device of the centralized charging cabinet; the control device of the centralized charging cabinet outputs control signals according to temperature values uploaded by one or more battery charging spaces, so that the refrigerating or heating unit of the centralized charging cabinet works, and the temperature of the battery charging spaces is ensured to be within a set range. In this embodiment, the cooling or heating unit (i.e., the air conditioning unit) may maintain a set temperature in a specific battery charging space, or may maintain a set temperature in all battery charging spaces. Whether cooling or heating is performed in a specific case is realized by comparing the current ambient temperature value with one or more set threshold values, which are set in advance; in addition, in this step, whether smoke is generated in the battery charging space can be judged according to the output signal of the smoke sensor in the obtained environment temperature parameter, if yes, the fire fighting equipment corresponding to the battery charging space is started, the battery is stopped to be charged, and an alarm signal is emitted; if not, continuing to charge the battery. In this embodiment, the smoke sensor is mounted inside the battery charging space and senses smoke emitted by smoking material disposed on top of the battery charging space due to a fire in the battery charging space; the fire fighting equipment comprises a dry powder extinguisher with a nozzle in the battery charging space. In one aspect of this embodiment, the smoking material is typically a strand of a material having a particular composition (e.g., pitch) that emits a large amount of smoke upon ignition to facilitate detection by the smoke sensor; meanwhile, because the smoking material is less, the negative influence can not be brought. In this embodiment, the smoking material is placed at the top of the battery charging space in a snake shape, and the placement mode enables the smoking material to be quickly smoked when a fire occurs anywhere in the battery charging space, so that the fire is detected, and measures are taken as soon as possible to reduce loss.
Step S15 is to charge the battery according to the battery status parameter: in the step, the control unit charges the battery to be charged according to the acquired state parameter of the battery to be charged; in this embodiment, the charging current is changed in accordance with the change in the obtained battery state parameter so that the charging of the battery is kept within a safe range. In one case, the charging characteristics of the battery to be charged can be converted into corresponding charging parameters to be stored in the control unit, so that the corresponding charging parameters can be called out only by obtaining the state parameters of the battery to be charged, and the battery to be charged is charged according to the charging parameters.
Step S16, no, if yes, go to step S17; otherwise, the charging is maintained for a period of time or the process returns to step S13 to obtain the environmental parameters and the battery status parameters again. Thus, monitoring is realized in the whole charging process, and the battery to be charged can be always charged with the best effect. In this step, whether charging is completed is judged by the charging current and the voltage of the battery to be charged.
Step S17, reporting completion of battery charging: in this step, the control device of the centralized charging cabinet is reported, the charging of the battery in the charging space is completed, and the connection between the control power supply of the battery charging space and the commercial power is cut off.
Step S18 warning: in this step, an alarm signal indicating that the cabinet door is not closed or an alarm signal indicating that the battery is not in place is issued, and after the step is executed, the process returns to step S11.
In addition, in this embodiment, before the above steps are performed, a battery replacing step may be further included, that is, replacing the battery that has been charged in one battery charging space of the centralized charging cabinet with the battery to be charged, specifically, the user carries the battery to be charged to reach the centralized charging cabinet, then directly takes out the battery that has been charged, and then puts the battery to be charged carried by the user into the battery charging space where the battery is taken away to continue charging. This is to save the waiting time of the user, and make it not wait, take the battery that finishes charging directly away to use. Fig. 2 shows the specific steps of this method:
in step S21, the user requests the charging, and the control device of the centralized charging cabinet requests the user to select whether to directly charge or replace the battery, so that the user can select the charging; in step S22, it is determined whether the selection is to replace the battery, if yes, step S23 is executed; otherwise, step S24 is executed.
In step S23, in response to the charging request from the user, the control device of the centralized charging cabinet searches whether there is a battery that has been charged, and if there is a battery that has been charged, step S25 is executed to receive the charging request and open the charging space cabinet door where the battery that has been charged is located; taking the battery which is charged, putting the battery to be charged into the battery charging space, and closing a cabinet door of the battery charging space; if not, indicating that the user requirement cannot be met currently, step S26 is executed.
In step S24, according to the user' S requirement, searching whether there is a free battery charging space in the centralized charging cabinet, if yes, executing step S27, opening the cabinet door of the free battery charging space, and placing the battery to be charged into the centralized charging cabinet; if there is no free battery charging space and the user demand is also temporarily not satisfied, step S26 is performed.
The invention also relates to a device for implementing the method, and the structure of the device is shown in figure 3.
