In one embodiment, before S7, the control module 100 determines whether the amount of electricity of the sub-full battery 230 is less than the preset threshold through the electronic load module 400, and if so, proceeds to the next step.
In one embodiment, when the electric quantity of the under-full battery 230 is greater than the preset threshold, the electronic load module 400 discharges the under-full battery 230, the electronic load module 400 detects the electric quantity of the under-full battery 230 and sends the detected electric quantity to the control module 100, and when the electric quantity of the under-full battery 230 is less than the preset threshold, the control module 100 controls the to-be-tested charger 210 to be in conductive connection with the under-full battery 230, and the power test module 300 performs a test with the to-be-tested charger 210.

In one embodiment, the LED light information includes color information or strobe information.
The charger test module 200 further comprises an I/O card 240, an idle relay 250, a full relay 260 and a not-full relay 270, a signal output end of the control module 100 is connected with a signal input end of the I/O card 240, an input end of the idle relay 250 is connected with one end of the charger 210 to be tested, output ends of the idle relay 250 and the charger are respectively connected with input ends of the full relay 260 and the not-full relay 270, an output end of the full relay 260 is connected with the full battery 220, an output end of the not-full relay 270 is connected with the not-full battery 230, and the I/O card 240 is respectively connected with control ends of the idle relay 250, the full relay 260 and the not-full relay 270.
When the charger 210 to be tested needs to be tested, the control module 100 controls the no-load relay 250 to be disconnected through the I/O card 240, the charger 210 to be tested does not charge any battery at this time, the control module 100 controls the power test module 300 to be started, detects a first power value of the charger 210 to be tested at this time, and sends the first power value to the control module 100; after receiving the first power value information, the control module 100 controls the no-load relay 250 and the full-load relay 260 to be switched on through the I/O card 240, and the no-full-load relay 270 is switched off, at this time, the to-be-tested charger 210 charges the full-load battery 220, the control module 100 controls the power test module 300 to be started, detects a second power value of the to-be-tested charger 210 at this time, and sends the second power value to the control module 100; after receiving the second power value information, the control module 100 controls the no-load relay 250 and the not-full relay 270 to be turned on through the I/O card 240, the full relay 260 is turned off, at this time, the to-be-tested charger 210 charges the not-full battery 230, the control module 100 controls the power test module 300 to be started, detects a third power value of the to-be-tested charger 210 at this time, and sends the third power value to the control module 100; the control module 100 compares the first power value, the second power value, and the third power value, which are actually measured, with a preset threshold, so as to comprehensively determine the input performance and the corresponding power loss of the charger 210 to be tested.
Thus, the intelligent charger test system for the electric tool is characterized in that the charger test module 200 comprises at least one charger 210 to be tested, a full-charge battery 220 and a non-full-charge battery 230 through the matching arrangement of the control module 100, the charger test module 200 and the power test module 300, the control module 100 can switch the charger 210 to be tested under different battery capacities by controlling the on-off of the charger 210 to be tested, the full-charge battery 220 and the non-full-charge battery 230, meanwhile, the control module 100 controls the power test module 300 to measure the charger 210 to be tested under different battery capacities, obtains a power value and feeds the power value back to the control module 100, thereby judging the whole input performance and the corresponding power loss of the charger 210 to be tested through the preset value of the control module 100, the obtaining of the power value of the charger under different battery capacities can be completed through the system without adopting a plurality of devices to respectively measure, effectively saves the cost and improves the working efficiency.
Further, in order to ensure the smooth proceeding of the test, the testing system of the intelligent charger of the electric tool further includes an electronic load module 400, wherein the electronic load module 400 is electrically connected to the under-full battery 230 and performs interactive transmission of signals with the control module 100.
Thus, when performing multiple tests, the charger 210 to be tested can easily cause the battery to be fully charged due to charging the battery multiple times, and thus cannot obtain the power value of the under-full battery 230 or obtain the power value inaccurately, so it is required that at least one battery to be tested is in the under-full state in real time, and the general under-full state is the electric quantity of the battery <90%, so we can electrically connect with the under-full battery 230 through the electronic load module 400, when the under-full battery 230 is not in the working state, the electronic load module 400 detects whether the electric quantity of the under-full battery 230 is <90% or not, and feeds the electric quantity value back to the control module 100, if the electric quantity of the under-full battery 230 is less than <90%, the test can be normally started, and if the electric quantity of the under-full battery 230 is greater than 90%, the control module 100 controls the electronic load module 400 to consume the electric quantity of the under-full battery 230, the test is not started until the amount of electricity of the under-charged battery 230 is less than a preset threshold. Through the setting of the electronic load module 400, the smooth proceeding of the test can be ensured, and the accuracy of the test power value can be ensured.
Further, in order to make the applicability of the test system wider, the test system for the intelligent charger of the electric tool further includes an LED analyzer 500, and the LED analyzer 500 and the control module 100 perform interactive transmission of signals, so as to obtain relevant data of the LED lamp of the charger 210 to be tested and send the data to the control module 100.
When the test is performed, the operating personnel judge the working state of the charger 210 by measuring the color or the flashing frequency of the LED lamp of the charger 210, so that it is important to measure whether the color or the flashing frequency displayed by the LED lamp of the charger 210 is correct, and if the color or the flashing frequency of the LED lamp is displayed incorrectly, misdirection is likely to be caused to the operating personnel. The color or the flicker frequency displayed by the LED lamp of the charger 210 to be tested in different test states is obtained through the LED analyzer 500 and is sent to the control module 100, for example, when the charger 210 to be tested does not charge any battery, the LED lamp displays red and does not flicker, at this time, the LED analyzer 500 sends the obtained information to the control module 100 to be compared with a preset threshold, if the comparison result is the same, the LED lamp displays no problem, if the comparison result is different, the LED lamp is damaged and needs to be replaced or repaired, thereby avoiding misjudgment of operators, and enabling the application of the test system to be wider.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
