Brief description of the drawings
Fig. 1 is device operating circuit principle schematic.
In accompanying drawing: 1, fender winding displacement is to jack apparatus; 2, current-limiting resistance; 3, light emitting diode (LED); 4, plug male; 5, fender winding displacement mouth; 6, plug female; 7, lithium battery.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
The present invention as shown in Figure 1, a kind of lithium battery protection board winding displacement welding sequence pick-up unit, feature is, comprise that fender winding displacement is to jack apparatus 1, described fender winding displacement is provided with n group light emitting diode 3 and the current-limiting resistance 3 of series connection separately to jack apparatus 1 inside, and described light emitting diode 3 and current-limiting resistance 2 circuit the two poles of the earth are provided with plug male 4;
Plug male is connected with plug female 6 in lithium battery 7 fender winding displacement to be detected mouth 5;
According to described lithium battery protection board winding displacement welding sequence pick-up unit, feature is, n is the lithium battery group number of series connection to be detected.
According to described lithium battery protection board winding displacement welding sequence pick-up unit, feature is that described current-limiting resistance 2 resistances are R=(V-Vf)/If, V is lithium battery voltage, and Vf is light emitting diode 3 forward conduction operating voltage, and If is working current.
Lithium battery 7 welds complete; fender winding displacement mouth 5 is connected to detection with fender winding displacement to jack apparatus 1; whether light and carry out whether check protection plate winding displacement mouth 5 welding sequences are correct fast and effectively according to light emitting diode 3 pilot lamp, cause fender to burn out or damage lithium battery because of winding displacement welding sequence mistake thereby solve.
In this example, the order that described fender winding displacement mouth 5 is welded to lithium battery 7 is to be welded to successively battery cathode from anode, and described light emitting diode 3 and current-limiting resistance 2 circuit are independent circuit, and parameter is consistent,
In this example, if described lithium battery 7 LiFePO 4 material battery normal voltages are in 3.3-3.4V left and right, if lithium ion material cell normal voltage is in 3.9-4.0V left and right; Light emitting diode 3 forward conduction operating voltage are in 3.0V left and right, in working current 20mA; Institute joins current-limiting resistance 2 and calculates R=(V-Vf according to formula)/If ≈ 100 Ω.
In this example, under normal circumstances, the explanation fender winding displacement welding that has at least one normally not light in multiple light emitting diodes 3 is wrong; Due to light emitting diode 3 both end voltage or reversal connection (according to oppositely not conducting of diode characteristic); light emitting diode 3 both end voltage are less than 3V cisco unity malfunction and light; light emitting diode 3 both end voltage > 6V current-limiting resistance protections; cause light emitting diode 3 pilot lamp not light; can judge fender winding displacement welding sequence mistake, cause fender to burn out or damage lithium battery because of winding displacement welding sequence mistake thereby solve.
The present invention designs ingenious, circuit structure rationally flexibly, convenient operation and application; Advantageous effect is effectively to test more intuitively fast, and reliability is strong, save the energy and cost; Realize lithium battery environmental protection.
Embodiment recited above is described preferred implementation of the present utility model; not design of the present utility model and protection domain are limited; do not departing under the prerequisite of the utility model design concept; various modification and improvement that in this area, common engineering technical personnel make the technical solution of the utility model, all should fall into protection domain of the present utility model.
