The present invention can monitor the electricity of vehicle battery and with low pressure warning function, when there is serious deficient electricity in storage battery, stand-by power supply can be utilized to complete the startup of vehicle, the storage battery of serious deficient electricity can also be repaired, use battery to be returned to the state of full electricity; The present invention also has the features such as volume is little, lightweight, simple installation.
Accompanying drawing explanation
Fig. 1 is operation principle block diagram of the present invention;
Fig. 2 is the circuit theory diagrams of controller of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, environment division of the present invention is made up of stand-by power supply, normally closed switch K1, normal open switch K2, insulated gate bipolar transistor speed-sensitive switch IGBT.In figure, V1 is battery tension, V2 is load and generator voltage, I is battery current.
The positive pole of stand-by power supply is connected with the positive pole of load and generator, then is connected with the positive pole of vehicle battery by insulated gate bipolar transistor speed-sensitive switch IGBT, is connected again between two tie points by normally closed switch K1 again; The negative pole of stand-by power supply is connected with the negative pole of vehicle battery with load and generator by normal open switch K2.
As shown in Figure 2, controller of the present invention is made up of vehicle-mounted computer ECU and connected voltage detecting circuit, current detection circuit, switch driving circuit.The bleeder circuit that two voltage detecting circuits are made up of resistance R1, R2, R4, R5 respectively and the filter circuit serial connection be made up of resistance R3, R6, electric capacity C1, C2, C3, C4 are formed, and are respectively used to detect voltage V1 and V2; Current detection circuit is that Hall current sensor and the filter circuit that is made up of resistance R7, electric capacity C5, C6 connect and compose, for detecting battery current.Switch driving circuit comprises IGBT drive circuit and K1, K2 switch driving circuit, and IGBT drive circuit is connected in series by resistance R8, triode Q1 and IGBT and forms, and drives IGBT action by triode; K1, K2 switch driving circuit is be connected in series formed by resistance R9, R10, triode Q2, Q3 and K switch 1, K2 respectively.
The course of work of the present invention is: after car key switch open, the present invention starts working, and first detects voltage V1, if V1 is greater than certain value, illustrate that accumulator electric-quantity is sufficient, do not need stand-by power supply, then the present invention enters resting state; If V1 is less than certain value, the deficient electricity of storage battery is described, disconnects K1, closed K2, is completed the startup work of vehicle by stand-by power supply.After having started, detect voltage V2, illustrate that when V2 voltage is greater than certain value generator is started working, now drive IGBT Switch Controller storage battery to carry out low current charge with pwm signal; When detection voltage V1 is greater than certain value, illustrate that storage battery departs from deficient electricity condition, closed K1, disconnect K2, the present invention enters resting state.
