As the preferred scheme, the LED lamp also comprises an output interface, the number of the wiring terminals of the output interface is matched with the number of the LEDs, and the wiring terminals of the output interface are respectively connected with the anodes of the LEDs.

Preferably, the output interface comprises at least one of a 2.0mm socket, a 2.5mm socket and a wire pressing head port.

As a preferred scheme, still include stabiliser, warning LED and diode, the stabiliser input is used for connecting device's input negative pole, the stabiliser output is connected with warning LED positive pole, warning LED negative pole connection diode negative pole, diode positive pole is used for connecting device's input positive pole.

Preferably, the voltage regulator comprises an LDO chip of type HT 7130.

Preferably, twenty LEDs and twenty second switches are respectively arranged.

The utility model discloses a many strings of battery performance debugging tool's beneficial effect is: when the ammeter needs to be accessed for testing, the first switch is opened, and when the ammeter does not need to be accessed, the first switch is closed, and other functional tests are not influenced. And the second switch matches with LED one-to-one, when inserting many strings of batteries and testing, only need with the second switch that the battery cluster number corresponds closed, can realize the capability test of many strings of batteries, when needing to switch over the battery cluster number, only need stir the second switch that the battery cluster number corresponds can, easy operation is convenient. Meanwhile, the second switch corresponding to the number of the battery strings is pushed, and the LEDs can be lightened by the corresponding number, so that the number of the battery strings is displayed.

Drawings

Fig. 1 is a schematic circuit diagram of the multi-string battery performance debugging tool of the present invention.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, the multi-string battery performance debugging tool includes a first switch, an ammeter terminal, a plurality of LEDs, a plurality of divider resistors, and a plurality of second switches, where the number of the second switches matches the number of the LEDs, the LEDs are connected in series with the first switch after being connected in series, at least one divider resistor is connected in series between the LEDs, the anode of each LED is connected to one end of one second switch, the other end of each second switch is used to connect the anode of the input terminal and the anode of the output terminal of the device, and the ammeter terminal is connected in parallel to both ends of the first switch.

When the ammeter needs to be accessed for testing, the first switch is opened, and when the ammeter does not need to be accessed, the first switch is closed, and other functional tests are not influenced. And the second switch matches with LED one-to-one, when inserting many strings of batteries and testing, only need with the second switch that the battery cluster number corresponds closed, can realize the capability test of many strings of batteries, when needing to switch over the battery cluster number, only need stir the second switch that the battery cluster number corresponds can, easy operation is convenient. Meanwhile, the second switch corresponding to the number of the battery strings is pushed, and the LEDs can be lightened by the corresponding number, so that the number of the battery strings is displayed.

The multi-string battery performance debugging tool further comprises an output interface, the number of the wiring ends of the output interface is matched with the number of the LEDs, and the wiring ends of the output interface are respectively connected with the anodes of the LEDs. The output interface comprises at least one of a 2.0mm socket, a 2.5mm socket and a wire pressing head port. The PIN is connected with the input end through the plug of the PIN and the PIN, and compared with the mode that a lead is welded manually and connected to the input end of a board, the connection mode of the input end is simplified, and the connection flexibility is improved.

The multi-string battery performance debugging tool further comprises a voltage stabilizer, an alarm LED and a diode, wherein the input end of the voltage stabilizer is used for the input cathode of the connecting device, the output end of the voltage stabilizer is connected with the alarm LED anode, the alarm LED cathode is connected with the diode cathode, and the diode anode is used for the input anode of the connecting device. When the input power supply is normal, the diode is cut off in the reverse direction, and the functions of protecting the voltage stabilizer and the alarm LED can be achieved; when the input of the input power supply is reversely connected, the input voltage is stabilized by the voltage stabilizer and then the alarm LED is lightened, so that the reverse connection alarm function is realized.
