Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Fig. 1 is a schematic structural diagram of an energy storage battery device with fault detection according to an embodiment of the present invention. Specifically, referring to fig. 1, the energy storage battery device with fault detection includes an energy storage battery pack 11, a charging detection module 12, a discharging detection module 13, a first processor 14, a second processor 15, and an environmental parameter detection module 10.
A charging port of the energy storage battery pack 11 is connected with an external power supply device through a charging line 16, and a charging control switch 17 is connected on the charging line 16 in series; the charging detection module 12 includes a charging voltage detection unit 121 and a charging current detection unit 122; the charging voltage detection unit 121 and the charging current detection unit 122 are both connected with the charging line 16, and connection points between the charging voltage detection unit 121 and the charging current detection unit 122 and the charging line 16 are both located at one end of the charging control switch 17 far away from the energy storage battery pack 11; the first processor 14 is connected to the charging voltage detection unit 121, the charging current detection unit 122, the control terminal of the charging control switch 17, and the environmental parameter detection module 10, and is configured to determine the charging state of the energy storage battery pack 11 according to information provided by the charging voltage detection unit 121, the charging current detection unit 122, and the environmental parameter detection module 10, and control the energy storage battery pack 11 to disconnect from an external power supply device when the charging state of the energy storage battery pack 11 is abnormal.
The discharge port of the energy storage battery pack 11 is connected with an external electric device through a discharge line 18, and a discharge control switch 19 is connected in series on the discharge line 18; the discharge detection module 13 includes a discharge voltage detection unit 131 and a discharge current detection unit 132; the discharge voltage detection unit 131 and the discharge current detection unit 132 are both connected to the discharge line 18, and connection points between the discharge voltage detection unit 131 and the discharge current detection unit 132 and the discharge line 18 are both located at one end of the discharge control switch 19 away from the energy storage battery pack 11; the second processor 15 is connected to the discharge voltage detection unit 131, the discharge current detection unit 132, the control terminal of the discharge control switch 19, and the environmental parameter detection module 10, and is configured to determine the discharge state of the energy storage battery pack 11 according to information provided by the discharge voltage detection unit 131, the discharge current detection unit 132, and the environmental parameter detection module 10, and control the energy storage battery pack 11 to disconnect from an external electric device when the discharge state of the energy storage battery pack 11 is abnormal.
Specifically, when the energy storage battery device with fault detection provided by this embodiment is in normal charging, the charging control switch 17 is closed, and the external power supply device can charge the energy storage battery pack 11 through the charging line 16. By providing the charging detection module 12 connected to the charging line 16, the actual charging voltage and the actual charging current of the energy storage battery pack 11 during the charging process can be obtained by using the charging voltage detection unit 121 and the charging current detection unit 122 in the charging detection module 12. The first processor 14 is connected to the charging detection module 12, and can obtain the actual charging voltage information provided by the charging voltage detection unit 121 and the actual charging voltage current information provided by the charging current detection unit 122, respectively. The first processor 14 may pre-store the standard charging voltage information and the standard charging current information, and when the actual charging voltage information provided by the charging voltage detecting unit 121 exceeds the standard voltage range, the first processor 14 may control the control terminal of the charging control switch 17 to turn off the charging control switch 17, so as to stop charging the energy storage battery pack 11.
The energy storage battery device may be used to store electric energy generated by a novel power generation device such as a solar power generation device and a wind power generation device. Taking a solar power generation device as an example, the power generation amount of the solar power generation device is severely limited by the light intensity of the environment, and in the midday time period with the maximum light intensity in a day, the solar power generation device generates more electric energy, at this time, the voltage and the current generated by the solar battery power generation device may be relatively large, and the energy storage battery pack 11 is easily burnt by the excessive voltage or current. Or, in a period of time with weak light intensity in cloudy days or in the morning and evening, the actual charging voltage or actual charging current generated by the solar power generation device is too small, which may result in low charging efficiency of the energy storage battery pack 11 or even no charging. In order to avoid such phenomena, the energy storage battery device with fault detection provided in this embodiment may utilize the charging voltage detection unit 121 and the charging current detection unit 122 to detect the actual charging voltage and the actual charging current, and control the charging control switch 17 to be turned off when the actual charging voltage or the actual charging current deviates from the normal charging range, so that the energy storage battery pack 11 is temporarily charged, thereby achieving the effect of protecting the energy storage battery pack 11. In order to refine the type of fault as much as possible, the present embodiment further provides an environmental parameter detection module 10, for example, when the charging current detection unit 122 detects that the charging current is too large, it is likely that the power generation efficiency of the solar power generation device is high due to the large light intensity in the environment. However, if the intensity of the ambient light detected by the ambient parameter detection module 10 is general, the current that is caused by the high power generation efficiency of the solar power generation device can be basically excluded, and at this time, the first processor 14, in combination with the information provided by the ambient parameter detection module 10, can make other reasonable judgments about the type of the fault.
Similarly, the energy storage battery device with fault detection provided by the embodiment closes the discharge control switch 19 when the energy storage battery device is normally discharged, and the external power supply device can discharge the energy storage battery pack 11 through the discharge line 18. By providing the discharge detection module 13 connected to the discharge line 18, the actual discharge voltage and the actual discharge current of the energy storage battery pack 11 during the discharge process can be obtained by using the discharge voltage detection unit 131 and the discharge current detection unit 132 in the discharge detection module 13. The second processor 15 is connected to the discharge detection module 13, and can obtain the actual discharge voltage information provided by the discharge voltage detection unit 131 and the actual discharge voltage current information provided by the discharge current detection unit 132 respectively. The second processor 15 may pre-store the standard discharging voltage information and the standard discharging current information, and when the actual discharging voltage information provided by the discharging voltage detecting unit 131 exceeds the standard voltage range, the second processor 15 may control the control terminal of the discharging control switch 19 to turn off the discharging control switch 19, so as to stop discharging the energy storage battery pack 11.
It should be noted that the energy storage battery device with fault detection provided in this embodiment may be used to supply power to external electric devices such as household appliances. In the process of supplying power to the external power supply device, the external power device may have a condition of sudden increase of current such as short circuit, and the current in the discharging line 17 can be obtained in real time by using the discharging current detecting unit 132 through the second processor 15, so as to determine whether the actual discharging current of the energy storage battery pack 11 is normal, and when the actual discharging current is abnormal, the discharging control switch 19 is controlled to be turned off, so as to prevent the energy storage battery pack 11 from being burned out due to over-discharge of current. Similarly, the discharge voltage detection unit 132 also has a similar technical effect of avoiding the energy storage battery pack 11 from being damaged when the voltage of the energy storage battery pack 11 is abnormal, and is not described again.
It should be noted that, in describing the energy storage battery device with fault detection provided in the present embodiment, the present embodiment utilizes the concepts of "external power supply device" and "external power utilization device", but this is only for better explaining the structure and function of the energy storage battery device with fault detection. In fact, the energy storage battery device with fault detection provided by the embodiment can be produced independently as a stand-alone device, or produced together with an external power supply device and the like. In addition, for the external power supply device, the solar power generation device and the wind power generation device are mainly listed in the embodiment, but readers will understand that the energy storage battery device with fault detection provided by the embodiment can also be used together with other types of power generation devices.
According to the energy storage battery device with fault detection, the charging detection module and the first processor are arranged, the charging information of the energy storage battery pack is obtained through the charging detection module, and when the first processor judges that the energy storage battery pack is abnormally charged, the charging control switch on the charging line is controlled to be turned off, so that the technical effect of charging protection is achieved; through setting up discharge detection module and second treater, utilize the discharge detection module to obtain the information of discharging of energy storage battery group to when the second treater judges that the energy storage battery group discharges unusually, the disconnection of the control switch that discharges on the control circuit, and then play the technical effect of discharge protection.

The wireless communication module 20 may transmit the failure signal generated by the first processor 14 to a control device located at a remote end, or may transmit the failure signal generated by the second processor 15 to a control device located at a remote end. Therefore, under the condition of charging abnormity or discharging abnormity, the control room can acquire the abnormal information through the wireless communication module 20 at the first time, and then send the staff to carry out timely inspection and maintenance according to the abnormal information, so that the inspection and maintenance efficiency can be improved to the ground, and the normal work of the energy storage battery device with fault detection can be ensured as much as possible.
