In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
On the contrary, the present invention contain any by claim, defined in marrow of the present invention and scope, make substitute, modification, equivalent method and scheme.Further, for the public is had a better understanding to the present invention, in below details of the present invention being described, detailed some specific detail sections of having described.Do not have for a person skilled in the art the description of these detail sections can understand the present invention completely yet.
In existing electrical bike charger market, producer is chaotic, and product quality is uneven, uses for a long time the charger of low-quality or charges in the unmatched situation of charge parameter, can cause damage to lead-acid battery, even the dangerous situations such as battery explosion can occur.
For solving the problems of the technologies described above, referring to Fig. 1, the embodiment of the present invention one has proposed a kind of lead-acid battery intelligent charge control method, arranges and can carry out the battery management circuit 21 of data communication with charger 1, default identification code in charger 1 and battery management circuit 21 in lead-acid battery module 2; Before charging starts, the step of advanced line identifier code coupling.
Existing plumbic acid lead-acid battery does not generally all have special charge protector, and the embodiment of the present invention arranges battery management circuit 21 in lead-acid battery module 2, thereby can realize with charger 1, carries out data communication.
Referring to Fig. 2, be depicted as the theory diagram of a kind of charging system of realizing lead-acid battery intelligent charge control method of the present invention, wherein, lead-acid battery module 2 comprises lead-acid battery group 22 and battery management circuit 21.
Battery management circuit 21 is connected with charger 1 with lead-acid battery group 22 respectively, comprises switch module 211, battery management module 212 and communication module 213;
Switch module 211 is connected on charger 1 and lead-acid battery group 22, is controlled by battery management module 212, controls the charging to lead-acid battery group 22;
Charger 1 is connected with civil power input, comprises charging module 101, control module 102 and communication module 103;
Charging module 101 is controlled by control module 102, for exporting charging signals;
Communication module 103 and communication module 213 are for setting up the data communication between charger 1 and battery management circuit 21;
The default identification code matching in charger 1 and battery management circuit 21; I.e. preset charged device identification code in charger 1, default battery identification code in lead-acid battery module 2, only, in the situation that charger identification code and battery identification code match, charger 1 could charge to lead-acid battery module 2.
Before starting charging, advanced line identifier code coupling, battery management circuit 21 receives the charger identification code information that charger 1 sends, and whether the judgement battery identification code built-in with it matches, if identification code matches, actuating switch module 211, charger 1 starts lead-acid battery module 2 to charge; Otherwise switch module 211, in off-state, cannot charge.
In a preferred embodiment, communication module 103 and communication module 213 are power line carrier module, adopt power line carrier module just can just can realize data communication by charging wire, realize charging and data communication one, without arranging again excessive data transmission line.
In the codes match that realizes charger 1 and lead-acid battery module 2, need to set up data communication and be connected, adopt communication module (such as power line carrier module) still relatively high on cost, but also increase the complexity of circuit.Consider that codes match is only the step before charging normal, after charging normal, can not need between charger 1 and lead-acid battery module 2, carry out transfer of data, the present invention proposes the data communication method of a kind of embodiment of being different from, by the magnitude of voltage variation of controlling on charging wire, realize data communication.
Referring to Fig. 3, communication module 103 is voltage detection module 104 and switch module 105; Communication module 213 is voltage detection module 214 and switch module 211;
